pc won't start - power supply failure?

Q: pc won't start - power supply failure?

hp pavilion a305w. 512 ram. (i can't look up cpu specs as it won't start) win xp, sp2
OK here's the deal. I play an online game that would randomly crash and give me crc errors that would directly reference a file in that game.
thinking that was a game specific error, i left it alone for the 5 days i went visiting for xmas. got home today, powered on the pc, and........nothing.
it will not boot.
so i unplug everything except the tower and the monitor.
still won't boot up.. no PS running, nothing.
so i unhook the monitor.. then it will boot. all systems are go, but i can't do anything with it....cuz the monitor isn't hooked up. so i go to hook that up, and as soon as it touches the back of the case (and there is no static here) the box stops running.
completely. as soon as i move the cord for the monitor, its all good. it'll boot again.
so any ideas on wth is goin on with this?
no i do not have another monitor to test with it.. its xmas eve, and i doubt any of my frenz will think this an emergency to leave their familys over.
please please please please help me figure out what is wrong with this thing. i have to get it working so i can trade it in for a better one, or i'm SOL for a pc for the forseeable future!!!!! (haha)
thans bunches in advance.

Preferred Solution: pc won't start - power supply failure?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: pc won't start - power supply failure?

Okay, this could be two things: the power-supply or the monitor, both of which you'll need to find another of, at least for testing purposes. If you get the power-supply then make sure it's the same type and make (look on your computer and give us the MODEL number for your specific computer, this'll give us the specs we need to determine what kind of power-supply you need). I don't think it has anything to do with your game, but it could very well have something to do with your graphics and/or your video card as well. Is it the power, or the dv15 pluggin (that's the plug where you hook it to the comp itself, NOT power, the other one) that messes it up?

Most likely this is a power-supply matter as you pointed out and that'll require a replacement. Those things cost alot, so if you can find a used computer at the dump or something or go to a local hospital and buy one for cheap, or have a friend with one they don't use cuz it's broke or something i'd do that, but make sure it's compatible!

God Bless and In Him,

I've read a few threads here on these forums and have found a few similar situations but nothing that really matches what i'm dealing with. Here goes:

I was playing a game when my PC made a short strange muffled hissing noise and then popped. The PC completley shut down like someone has pulled the plug. Almost right away it smelled like an electrical fire. I figured this was the power supply (NZXT 550W) since it is around 4 years old and has been through a lot.

The following day I went to best buy and picked up a Thermaltake TR2 600W PSU and installed it. After plugging in the main power cord from the wall outlet I switched on the PSU itself. Inside, the SB PWR light on the MB lit up. I thought this was good news. I hit the power button for the whole system and
the CPU fan moved slightly and the front LED light quickly flashed on and off. Then nothing. I checked to make sure all connections were snug. Same result.

Ok so lately I have been getting a BSOD at very random times and it looks like a Diver Power State failure. SO all of my friends and every website I go to makes it seem like I need to get a PSU. Right now I have a Quad Core and a 8800GT and 375W PSU. So my friend told me to get a new 700W PSU.

So, if the only fix is to get a new PSU? I tried to rollback my GPU driver but it didn't help.

So any ideas?
 

A:Driver Power Failure = New Power Supply?

You're greatly risking the health of your whole computer while running with such underpowered power supply. Do yourself a favour and get a quality PSU. http://www.newegg.com/Product/Product.aspx?Item=N82E16817341010 That's the cheapest one that is enough and of good quality that I could find with a quickish search.

hi guys, my friend phoned me tonight to go round and have a look at his computer that he was having problems with.

he said the computer was working fine last night but when he switched it on today it wasnt booting up and was asking for a disk or something, i automatically assumed that he had a hardisk problem n told him to power it down and i would be round to have a look at it.

i went round earlier tonight and the computer wouldnt switch on when pressing the power button.

checked the power cable and that it was turned on at the back of the tower, do i have a power supply failure?

My desktop kept restarting itself anytime I try and do anything very intensive (games or movies) for very long (20 min to an hour). No BSOD, and infact when the computer shuts off, it turns back on and then "begins" shutting down (as though it never finished the sequence). I had this problem until I replaced the PSU. Now the problem has returned.
I just purchased a new PSU a month ago, as my old one tanked after a year(750 Watt 80 Plus Gold EVGA) and replaced it with the 1300 watt model. I could understand such a low watt model tanking after a year under the load I had, but the new one going after a month? What is the likelihood?
I'll start from the beginning: 18 months ago I built myself a new setup. My power supply failed around 3 months ago, it was an EVGA 750 watt 80 Plus Gold, and when I used my PSU tester at least half the lights never lit up.

Right....so i was surfing the web on my main PC then all of the sudden windows just goes through the shut down process and my computer turns off.I power it back on to find that the computer wont boot,so i power it back off and on again then it boots normally....

I'm in windows again (normal mode) then the computer shuts down again about 20 seconds after logging into windows.I'm thinking it's one of those shutdown viruses...so i boot up again into safe mode to attempt at virus scanning then,even in safe mode,shuts down once again.I repeat this 3 times.I know this is not a heat issue because my bios was reporting a CPU temp of only 38 degrees celsius and my video card is a rather low end one and it doesnt really produce heat.

Suspecting that it is a PSU or perhiperal issue,i start to troubleshoot by unplugging one device at a time.After unplugging the first device (hard drive),and attempting to power it on once again,the damn thing doesn't boot AT ALL (no beeps or post screen).I turn it off,try to turn it on again...now it won't power on at all.I unplug the AC cord from the PSU then plug it back in to find that it powers on by itself once the AC power cord is plugged in (with still no successful boot).I unplug everything else except the motherboard with the same effect,no boot.The power button on the tower does not respond (wont turn on,wont turn off and the LED light is off)

You always need a good power supply anyway as it prolongs your components life. I would recommend Antec, enermax or corsair for a power supply. Saying that it might be "dead RAM". If the RAM is not working properly the computer won't start. Got any friends who will borrow you a power supply for testing?

My machine has been acting rather funny within the last few weeks. I suspected it to be a virus, but that possibility has been completely ruled out. My computer specs are:

AMD Athlon 2ghz
Geforce 4 TI 4200
512 mb ram
333 mh ram
PC 2700

The problem is that she's getting increasingly slower. Start up is taking ages now. When I run music it takes up nearly 90% of my CPU. Starting up another program while I have music running will skip the music for about 3 minutes at a time.

Programs are taking longer to start up. Yesterday my CD drive wouldn't even open, I had to restart my system. The printer takes forever and my download rates are suffering dramatically from what they should be.

My husband suspects it to be a problem with my power supply, but I'm wondering if there's any other possible problems.

No, I don't have any trojans, viruses, or backdoor spyware running. I've ran at least 6 different programs to detect these things.

Thanks in advance for any advice.

My computer has been dead in the water for several weeks now and I am not sure what the problem is. I think an electrical storm may have fried my power supply, but I am not sure. Here are the specs on my "clone" system:

MB: Intel D101GGC (w/onboard audio and video)
CPU: Intel P4 511 LGA775 (04A Platform)
PSU: RaidMax ATX 12V 380W
RAM: 1GB (2-512MB) PC-3200 Single Channel
DVD: Sony 16X
CDRW: Sony 52X/32X/52X
HDD: Maxtor SATA 200 GB 7200 RPM

When I opened up the case and looked inside, with the power cord plugged in, the motherboard has a green LED light that indicates the MB is receiving power. When I tried to turn on my computer I guess it is the CPU, but it makes a funny clicking sound and the the fan over the CPU tries to turn, but stops immediately. When I turn the fan blade with my finger it turns freely, so I know it is not the bearings in that fan. I have been to Intel.com and followed all their recommended steps to troubleshoot this problem, but no solution, as of yet. I have unplugged all devices from the power supply, except the 4-pin (12V) power connector and the 20-pin main power connector and the CPU fan and nothing has changed. What else can I do? What is a definite indicator that it is a power supply problem and not a MB or CPU problem? Please Help! Thanks!
 

A:Power Supply Failure?

Have you also unplugged the HardDrive and CD/DVD drive, and floppy (from the motherboard end)?
Remember you just want it started

The fan may be thermostatically used, that is it won't start running until the system is warm.

Reseat Ram?

Ideally test with another PowerSupply
Here's a good BenchTest Guide

You should also try dispersing all internal voltage, by holding in the power button for 30secs whilst the power lead is out.

I'd also recommend removing any internal PCI card attached
I've even have faulty CPU fans cause this error

A couple weeks ago my computer all-of-the-sudden stopped turning on. When I press the power button, the lights turn on and the fans start spinning for less than a second, then everything turns off. If I press the power button again, nothing happens. I can get the computer to turn on for a split second again if I either unplug the computer, wait, and then plug it back in. The first thing that came to mind is that the PSU has died. Does this sound legitimate?

If the PSU has died, does anybody know of an inexpensive replacement that would work with my mobo and power needs? Thanks!
 

A:Power Supply Failure?

Typical of a power supply failure.

And the HP m7650n does not have enough power in the supply for that GeForce 7600 GT.

Borrow a power supply to test in yours, or get yourself a power supply tester such as the Apevia Power supply tester for about $10 - $12

Or just buy a new and quality power supply... locally or on line.

You have to be very careful to get one of the exact same size dimensions and with the same sockets... If you don't have a source, www.directron.com has a huge number from which to choose.
Good luck.

The past 2 weeks, I've had to press my "Power On" button 2 or 3 it before it comes on. This happens about every other day.
The last time this happened, I had to replace the power supply and that was only 2 years ago. Surely they last longer than that?

Any ideas what would cause this?

Also, is it ok to leave my computer on 24/7 until this gets resolved? I'm afraid that one morning I won't be able to turn it on.

Hello,

I live in Rancho Bernardo, CA and when we were evacuated, I disconnected my desktop and took the computer case with us. It was in the trunk of my car for 4 days. (not good!) After returning home,(we were one of the fortunate families) I reconnected my computer and started it. It posted like usual, went to the XP startup screen and then went to the black screen that gives the options for safe mode, etc. I tried to start it in safe mode but it would not. It only opened some of the start-up files and then stopped.

I reseated the ram, video card and disconnected all of the drives other than the HD. I tried the "normal start". Same thing happened. I changed hard drives, put in another video card and restarted. The colors then changed to something other than normal, butt still would not boot past the startup screen before the welcome screen. It goes to black and there is a flash of a blue screen with text on it but it does not stay on long enough to read. I also tried the "last working configuration" with the same results.

The cooling fans now seem to speed up and slow down in a cycle. The bios shows normal voltage to the processor and the temps look normal there. I have a Antec Sonata with a 380W Power supply. It is 4+ years old. It only has one 12V rail. Could this be my problem?

A:Power Supply Failure?

I am a little confused. does the computer run and just not boot?

typically a PSU will blow and never turn back on. on occasion (as happened with me) a faulty transistor will cause power to cut out after the computer is on for a little (this prevents damage to the board and other components).

if you disconnect the harddrive, and power up to the bios screen, does it run okay?
also, have you tried a memtest? http://www.memtest86.com/

if the computer runs for awhile with no HDD, then it is most likely a HDD or software problem

My "home-bilt" desktop running Win98SE has been hanging up on boot-up, so I decided to do an "over-the-top" reinstallation. I put my Win98SE CD in and rebooted, instead of loading the installation CD it booted up to the installed copy of Win98SE. This happened Twice ??

To check the boot sequence I went into BIOS and as I expected it was -
1) floppy
2) CD drive
3) hard drive

While I had BIOS open I noticed there was a line that read something like -
"CPU overheat protection" OR "Inoperative CPU fan protection"
followed by "Disabled" in RED letters, I changed it to "Armed"

BIG MISTAKE !!! -- If it ain't broke -- don't fix it !!!

When I rebooted, ALL THREE DRIVES [hard drive, CD-ROM & CD-RW] lite up like they were all trying to boot at once ???? After 5-6 seconds tower shut down.

After a couple of tries I moved the tower to the kitchen table and opened it up. I had a power cable BUT NO monitor. It went through the same 5 second shut-down, but I noticed the fans [CPU, AGP card & rear wall of case] were all running [for 5 seconds]

Then I looked into the power supply grille and noticed THAT FAN was running in "fits & starts". Using a pencil I noted the fan "spun freely" when the power was off.

As the title suggests, my Lenovo h50-55 may have a possible PSU/Motherboard issue. Because upon turning it on the screen is basically black but the tower will still come on and all the fans will spin still. I have tried taking the ram out and swapping it around, taking the graphics card out and using the monitor ports on the motherboard (VGA) and nothing works. It also doesn't beep or anything upon turning it on and the HDD light is very dim. I orignally thought it was a HDD problem but i managed to install windows 7 on it and it worked perfectly. The monitor works fine too, as i plugged a games console into it and it's fine. Yesterday a family member took it to a PC repair shop and i wrote everything down that i had attempted on it the tower, but he claimed the power supply was "16" and it couldn't be tested to see if it was broken. As modern machines have "20-24" regarding PSU, but i have zero clue what he is talking about and i'll have to call him today and ask lol. I really like the machine too and i don't want to replace it after only having it for two years, so any help would be great. Thank you.

Hi everyone,

First off thanks for any help in advance. I worked in tech support for 3 years and this problem is somewhat baffling to me. unfortunately, I don't have all the replacement parts I was used to working with or the test systems. So I am trying to figure out what is failing before taking 3 trips to the store buying and testing different parts.

so what happened...

First moved to new apartment, never had problems before that. within 10 minutes of turning computer (desktop), i was standing on the other side of the room, and system just turned off (didn't crash, just zap, no power). I didn't think anything at the time since i was still moving and messing with light switches and thought i randomly hit a cord or something.

a couple days later, after i had been using the computer for a while, games and all, one day i turn it one and it barely gets to the desktop and zap it turns off. First i think crash so i hit the power button to turn it on and nothing, no flicker no nothing. so i think power supply burnt up or MB fried. I curse in my head and go eat dinner. I come back after dinner and press the button for the heck of it and what do you know it works. worked all night, played games, cranked up the GPU. nothing no problems. i shut it down, check all the wiring in the back, everything looks solid. the entire 3 day weekend, worked great, lots of gaming.

My computer won't start up anymore...

The fan for the CPU comes on, but the rest of it won't (with the exception of the HDD and TURBO lights, which turn on but don't blink which reflects the sort of FROZEN mode it's in)... I dont' hear the HD boot... and it has been sporatically restarting itself all day (each time it reboots it seems to restart Sooner than before).... so it may be a short in a wire... I''m not sure.

The power supply seems to emit a hissing which after a few seconds dims or disappears.

I've checked all cables and they are in securely... no extreme things have happened to the computer, and before it went down it was SCANDISKed, DEFRAGed, and scanned for viruses (though I know for a fact it was clean)... it also has a firewall so it wasn't 'outside' interference.

A:Best Guess, Power Supply failure

Unplug everything from the power supply other than the motherboard and see if you get a picture. If so, plug in the floppy drive, then something else and so on.

If still no picture, try pulling all cards but video out.

Anything connected to the motherboard, when damaged, can cause what you are describing. Come to think of it, even a bad keyboard, mouse, or printer cable could do it.

Quick question:
On the bottom of my 3.5yr old Toshiba A70 Satellite laptop it tells me the power supply is DC19V - 6.3A

If I understand this to be 19volts -6.3 Amps.... then will an alternate/generic power supply of 19Volts -max5amps cause my computer to shut down unexpectedly and repeatedly after 4-6 wks of problem-free usage.

After I changed my power supply (prev. supply just stopped working) the computer worked fine for a while...then started shutting down unexpectedly. On one particular day it shut down repeatedly 3-4x, and now wouldn't start properly. (Safe mode start screen that despite selection would reboot back to this screen ONLY)

I brought it to Tiger Direct for repair, explaining problem.....they suggested they reload the OS and found the orig. hard drive to have bad sectors and further suggested a NEW hard drive. They also suggested so many shutdowns may have damaged the hard drive leading to the problem. It was only after they reinstalled OS and new hard drive that they found it still shut down unexpectedly. I was annoyed now....as this is when they realized the power supply "wasn't enough AMPS" and blamed problem on this. I have a personal guarantee from manager now that they will refund my repair costs if I get a new power supply with proper amps....and still have problem. (this would apparently indicate motherboard problem and not power supply and I wouldn't have needed new HD)

My computer was running smoothly. I loaded some Windows Updates and after it installed those the computer froze. I had to do a cold shut down because there was no other choice. The computer would not boot up after that. It was late in the evening when this event occurred so I did a shut down and tried to power up the system the next morning. When I turned it o it would not do anything and the light on the power supply was blinking. I had seen this before and knew it was a power supply problem. I had another power supply so I installed it and got everything back up only to find it still would not boot up. I had my operating system on a SSD. I can get Windows to load of course from the CD drive. It will let me attempt a repair but it finds my other 1T drive but does not find the SSD Drive. When I go into the Bios I can see the drive (SSD) listed there along with the other two. It is like it can not find the drive to boot up to. There is some files I need from the SSD.

I followed the Dell support recommendation to refresh the power state without any success. I have checked the Power supply connections and all seems right. The light coming off the network cable is orange. I'm connecting to hte INternet via a wireless adapter, but clearly that's not a solution.

In addiiton, a possible related problem comes when I attemtp to upgrade to Vista. In the first restart during the install, I get a blinking cursor in the upper left corner of the screne after the Dell splash screen, apparently aborting the install. I've reverted to early OS (XP) at boot.

APpreciate any ideas.

Hello there!

There's a really critical issue which has been pestering me and making things truly hard, preventing me to fully make use of the PC.

A long time ago, I was struck by a problem where, upon being started, the CPU lights and fan would be turned on, but not the mouse lights nor the monitor display. Basically, it wasn't fully 'waking up'. After attemps of restarting it manually, it'd end up like a car that dies right after ignition. A tech visit and a power supply upgrade solved it, but, since then, at least in 2 occasions, the problem took place, isolatedly.

Today, by the morning, I was browsing the PC and opened a program, but, after a few minutes, a flashing W8 BSOD appeared for a second and the PC was restarted - before it could be rebooted, though, the previously mentioned 'fake awakening' problem stated. I spent too much time trying to turn off and on the system, to no avail, while only having it 'turn on the lights and fan', but not being fully started. After much insistence, and some pressure on the PS cable, it was finally turned on. The system started as usual, except for a single, fatal issue.

The system simply -won't- recognize any kind of network connection, at all.. I do have an internet modem, as well as wifi-router, and when I first installed W8.1 I didn't need to do anything - I simply plugged the network cable and it was recognized/connected. But now, it seems that the system won't recognize it. I tried to restart the connection, tried to re-pl... Read more

A:BSOD > Power supply failure > No network recognized;

Alright, managed to find a solution!

Basically, this guide was extremely useful:

When your ethernet won't connect | PCWorld

Just had to uninstall the Intel adapter and it reinstalled the driver with a reboot, which solved the issue.

...So many hours lost until I tried it! There goes my saturday, lol..

Cheers!

 My T580 suddenly one day stopped reading my external USB-C hard drive, I tried updating the drivers and several other suggested repairs with none of them working. The power light on the drive would come on but the computer didn't read it, verified with a second drive and they both work on my other computers. Looking at the timeline, I realized that this happened while the computer was still within it's warranty period, but I was busy and just let the problem go. Then two weeks later the computer just shut down on me and after letting it sit with the lid closed for a while, it was able to restart and I got a warning message at the BIOS screen that "The Power Adapter is of lower wattage than the one supplied with the machine" or something along those lines. Once booted up I was able to see that battery nuber one was fully depleted to 2% and the 2nd battery was at 99%, it then shut down on me again. I ordered a replacement power adapter to test and got the same message and the same symptoms, the computer would basically trickle charge at a rate slower than it consumed power, at this point I finally called customer service and started a repair ticket, this is when they told me that the computer was three weeks out of warranty....I send it in and a week later recieve a repair estimate of $589 to replace the whole motherboard. I called right back and complained that this computer was having problems before the warranty was up and was simply told it was out of warran...

a few hours ago, my mom brought home a brand new Acer Travelmate 4603WLCi laptop. after connecting the AC adaptor to the laptop, I turned the thing on. it worked just fine, and the Acer ePower Management software showed 33% battery power and still charging.

I was playing Solitaire back then, only for like 20-30 minutes, when suddenly the laptop just died. plain died. without shutdown.

so I turned it back on, and it went back on. only for like a few seconds after the Windows XP splash screen showed up, it died again. this time, I can't turn the thing on again.

I checked the adaptor cable that connected to the laptop, it's plugged firmly. however, the 'battery charge' lamp did not lit. I disconnected the adaptor cable, tried to turn on the laptop, it didn't work. I tried removing the battery, re-installing it, then tried turning it on again, also didn't work.

so I re-plugged the laptop to the adaptor, and thought that it'd charge up. but after 3 long hours of (useless) waiting, it's still not showing any signs of life.

I assume that this is a power adaptor failure, because when you connect the adaptor to the laptop, the 'battery charge' light is supposed to lit and you should be able to power-on the laptop. but hey, if the adaptor fails, aren't I supposed to be able to power-on the laptop by just the battery?

well, that's all I can tell for now.
thanks in advance for any advice(s) given.

cheers!

Hi Dhaninugraha:

The situation you described back then, now looks quite familiar to me.

The same happened to me last night. My Acer Laptop just died, just as you described. I did all the things which are common things to try to make it back working again...NOTHING !

How did you back then solve the problem. Did you find out what the failure was?

I would really appreciate any help you can provide.

Good day everyone,
maybe someone can give me some 'light' on this issue.

I have identified this as being a power supply problem, however, it may be related to another component within the mother board. This is what happens:

Since a couple of weeks back, I've noticed that my machine sometimes just won't boot up. The specifics of the PC hardware I assume are unimportant at the moment but just for the sake of explanation let me tell you that we are talking about a tower PC (de-branded HP P4, which as you all know that means, it has no support from its OEM.) Anyhow, the problem is that sometimes it just did not start up by pushing the power on button. Some of you may think it could be due to a problem with a loose cable or the sort, believe, that is not the case.

Well, this has been going on and off but since yesterday, my PC has been even more stubborn to power on. Today, after even removing all external cables and trying a few things........it did not power up, no fan, no sign of life but just a green light (I assume it's an LED) just below its power connector that, while the problem existed, it was blinking green. I even removed any cable from the HDD, DVD and any other power connector and still the same behaviour.

Ok, after trying this and that, I could finally make it boot up (by the way, I'm writing this from the same machine in mention) but I'm affraid this may happen again and probably it's a sign of something worse to ... Read more

That Bestec is really a piece of crap. Go get a Fortron 350W or higher PSU, and your problems are over. Check first if the PSU to motherboard connector is a 20 or 24-pin version and get the appropriate 20-24 adapter with it if necessary.

First of all this occured when the electricity went off one day. I had my computer connected to a ups and a safety power hub but i didnt manage to shut it down before the battery of the ups went off so it forced closed on its own. After that the led of the power supply, not the one on the psu but the one which is located in the chassis in front where the hdd led is as well, started flashing and the computer wont start at all. I started turning off and on the power supply button on the psu and i could hear a noise not a loud one like the one you get with a ram or w/e problem but a silent "" vzzzz" thinky. After multiples swith off and on from the psu button the sound stoped and the pc started. However when i shut it down again the noise is there again and now i cant start it again. Now i want to buy a new psu in order to fix the issue but i am not 100% sure if it's the psu's failure. Any ideas if it's the psu or something else?
 

A:Flashing power supply LED and PC won't start

That sound like a problem with psu to be sure get yourself a psu tester you can get a good one for around a 10 on ebay also take a look at your mobo to see if there is damage there also check your ups and safety hub.

I had some intermittent shut downs before the power supply finally totally crapped out. I have an HP Pavillion. I first bought a 750 watt supply from Tiger direct, but it wouldn't fit in my case. BUT, I did hook it up and make sure that the computer started up and ran ok. It ran fine. NOW, to replace that, the only thing I could find that would fit was a 350W diablotek. My problem is this, Now, when I hit the power button, the power supply fan turns on, but nothing else. When I turn it off, a power surge spins the cooling fan and the cpu fan.
The side note would be that when I was putting in the power supply, the heat sinc was in the way. When I pulled it out, I didn't realize that the cpu came out with it. I jacked up the cpu when reinstalling the sinc. I bent some prongs. I have replaced it with the identical cpu and still have this problem. Any ideas??
 

A:No start after a power supply replacement

What was your power supply wattage that you replaced? Did you test to see if the Diablotech is functional, i.e. test it with a multimeter?

Hi there,

I've been having some power issues with my laptop for a while. For some time now, my laptop has been constantly losing power and shutting off, regardless of whether I am running off the battery or the power supply. There does seem to be inconsistency as to whether the computer is getting power from the supply (it will be plugged in and off, and sometimes the light that indicates that it's charging will be on, and other times it won't.) I've also noticed that the power supply, as well as the bottom of the computer, get extremely hot. Sound like a bad power supply, or something else? I just think it's weird that it dies regardless of whether it is running off of the battery or the power supply. Perhaps the battery isn't getting power and it thinks it is?

Thanks for your help!
 

A:Laptop will not start. Bad power supply?

You don't tell us which laptop you have, but the odds are that the power cable connection into the laptop has failed because the socket is coming off either the power controller or the motherboard. An unstable connection can arc and cause heat. You need to get this fixed before it does any more damage and becomes unrepairable. A decent laptop repair should do this for less than $200/100 or local equivalent.

I have a Packard Bell computer S610-Pentium 233mmx that had the power switch toggles on/off repeatedly by a 2 year old. Now the system will not start. The cpu fan and the power supply fan start to turn then stop when the main power switch is turned on. I figured it was the power supply, replaced it and the new one does the same thing.

Hi. Recently got a brand new PC on an auction website and have had nothing but trouble from it. Today it's PSU started making a continuous extremely loud whining noise like a jet-liner taxiing on the airport, and the whole system was going crazy; the OS kept crashing etc, and before long it crashed again and could not be restarted. This prompted some Web research on the PSU (an ISO-500PP 420 Watts) and was not surprised to see that they have got an appalling reputation with fake "technical specifications" on the label. Am not writing this for help advice, as the PSU is stuffed. Primary reason for writing is to warn people, if you are buying a PC make sure that the PSU is not an ISO!!!

Have a power supply that most of the time powers on when push-bottoned.

Sometimes doesn't however. And I have toggle the main switch on the rear, the power supply itself, to reset.

Sometimes after doing this it will start all by itself. Sometimes I have to hit the pushbutton again.

It may take a couple times...

CMOS battery I'm guessing is okay - settings seem to be holding. Think I did it maybe three years back.

Hoping to not have to do the power supply again it is so tight to work in. (Antec case ).

As I understand, the Yoga is designed so you wont be able to turn the computer on without having it connected to the charger, which I find really annoying. I understand the problem with having the on/off button on the side and you can accidentally turn the computer on if you bump into a wall. But is there anyway to deactivate this safety function so I can turn off my Yoga 720 completely and then turn it on again without using a charger? Or is the battery so powerful that i should constantly put it in sleep mode when i move places without the power supply?

Hi,

This is a problem I had since a few months, but back then it wasn't that irritating. Sometimes when I tried to start my computer it would start up mechanically, so to say; all the fans were working and so were the HDDs, but not the BIOS. Nothing would happen, and the monitor was ever idle. A simple cold reboot usually solved the problem.

Now, like I mentioned, the problem got serious. The computer won't start at all, i.e. nor the fans, nor the monitor, nor the HDDs will ever start up. It just keeps restarting itself every second without any enhancement. I also found a solution for this problem by setting the power supply to 0, and then back to 1 after a few hours(!). Restarting after just a few minutes doesn't work. What's the matter? Have you ever encountered such a problem?

So I just recently purchased a new desktop as my laptop fried. I bought this desktop with getting a new video card and power supply in mind. I purchased an ATI Radeon HD5750 which requires one of those 6 pin power cords. The new power supply had what I need.

When i switched out the old 250W for my new 500W, I received no results. The computer would turn on, all fans would run but I would get nothing on my monitor. The motherboard green light would also turn on. When i swapped back to the old power supply, everything still works great. Any troubleshooting tips? Im told that this might not be a great power supply either. Thanks in advance.

computer for a few days you would press the start button on the tower and it wouldn't start right away but then after a few sec would come on. Yester day I tried it twice I pressed the start button on the tower and you could hear the power supply try to start but would die and the computer would not come on. so about the thired time press the button and nothing, would even try to start. I figured it was the power supply. I put a tester on the power supplyh and it said it was bad, so I bought a brand new one put it in and it still would n't do anything just dead.I tested the new one and my tester sasid it was bad, I changed it for another one and the store I bought the 1st one from tested the 1st one and there tester showed it was good, so my tester must not be working. Anyway I plugged the 2nd new power supply into just the motherboard and the harddrive and the little line that goes to the cpu and then plugged it in and still nothing , the computer just acts like it is dead, Can anyone help me with what else I could check? I checked the cords and the wallplug in etc is there anything else I can do or is it the mother board? the computer is only about 3 years old, its dell, can anyone help?????

Hi everyone- This is my first time here and I need help!! I'm a newbie and not real technically advanced, but here's my problem... A few days ago I was trying to connect my scanner to a USB port and I noticed my mouse got stuck. I hit the power button on the front of the computer to turn off. I rebooted and then I couldn't enter my windows password because my keyboard didn't work either! I then turned off the computer from the reset button in the back. Then I flipped it back and tried to power on my computer and it has never turned on again! I should mention that when I try to turn on the computer there are no sounds, no fans moving. It's just silent and dead. It doesn't try to do anything. Could it be the power supply or motherboard? I tried using different outlets, and changed out the computer cord that runs to the outlet. My friend helped me build my computer about 2 years ago. I have left it running mostly 24/7, which I guess isn't good. Could I have worn out my computer faster? I don't even remember what kind of mobo I have or really anything (I have to look and my friend ordered the parts 2 yrs ago). The only repair I've ever had to do on it was replace the fan about 8 months ago. My friend instructed me to open up the computer and see if the wiring from the power button to the motherboard looked ok and it looked fine. I just wonder if the keyboard/ mouse problem first gives any hint to what could've happened. There wer... Read more
