I have had this H50-55 for sometime, several years and suddenly it ask for a bios password when I try to enter the bios to change the boot order.  I have no clue what it is. I hate passwords and NEVER use one unless forced...What can I do?

A:Lenovo H 50-55 Bios password suddenly appears when trying to enter bios. I don't know it.

my guess is that your cmos battery died and it wants you to set day/time.  There is no backdoor password.  The choices are remember the PW or replace the motherboard.

Hey everyone, I was just wondering... My power supply has 2 fans in it, and both are auto speed. One of the fans is decently quiet at full speed, but the other is REALLY loud. Is there any way to disable the auto fan speed? Can I cut the wires to it and hook it up to an external fan controller somehow? Its the only fan thats making my computer loud... and I would really like to fix that. Thanks to all who can help -Dennis

Hello. I believe my computer suffered some sort of power surge due to a lightening storm. When I left in the morning, my computer was on but when I returned home, it was off. I tried to turn it on, but got nothing. After several times of pressing the on button, it sounded like it wanted to start up...the fan came on for maybe 2 seconds and then evertyhing turned off. I tried connecting another power source from another computer and this time the computer sounded like it was going to start up...the fan came on for about 5-7 seconds and then everything shut down again. I tried the original power source in another computer and it worked fine so I know it isn't the power source. Now when I try either of the power sources in my computer, I get nothing at all.

Any suggestions??? Thanks!
 

A:Power Supply ok, but won't turn on

Hello and welcome to Techspot.

Mmm doesn`t sound good.

Open up your computer and disconnect everything that`s not required to boot.

I.E just leave the hdd cpu psu and ram. If your computer starts to boot normally, then start adding the other components one at a time, untill you find the culprit.

If none of the above works then I`m afraid that your mobo maybe dead.

Regards and good luck Howard :wave: :wave:

Hi: I am tired of the ?soft shutdown? gimmick on all modern PCs. [If I wanted a Mac I?d buy a Mac!]. I'm now building a new PC and I?d like to get back to a single switch on an AC line outlet box where PC, Printer, VDU, etc. all come-on or go-off together without a need to push more buttons (like the old ATs). Can I accomplish this by simply shorting P/S plug pins 14 and 15 together permanently and ignoring the motherboard connected pushbutton or is there a downside to this seemingly simple solution?
 

A:Power Supply turn-on

Shorting those pins together long term can result in damage to the psu. I wouldnt recommend it.

I just built a new old computer using leftover parts and a motherboard & CPU I bought for $30. The thing is, if I use one stick of ram, the thing is pretty stable, but it crashes sometimes in games and stuff. If I use two sticks of ram however, it won't even load into windows, it just crashes while in the XP's loading screen, sometimes it just auto restarts, and sometimes it blue screens really fast and then auto-restarts. I remeber seen a error like "page fault in non-page area" or something.
The old case I have has a 200W power supply, and in the computer I have a DVD rom, a CDRW rom, 2 harddrives, a NIC, and a soundblaster live! and a rage128. I was wondering, what are the chances of the crashes are due to the lack of power? I know 200W is pretty low, but I thought that if I didn't have enough the thing won't power on at all. could all these crashes/restarts be due to the 200W power supply?

Hey everyone, my friend called me up last night and told me that he couldnt get his computer to turn on at all. When I tried to turn it on, nothing happens. No fans spin (not even for a split second) as if the PC isn't plugged in at all. I tried re-seating his memory, his video card, etc and still nothing.

His PSU has a green LED on the back of it that blinks when its plugged in to his PC. As a test, I installed it in another PC and it works perfectly and the green LED stays on (not blinking).

After figuring out that the PSU does work, I'm assuming that his mobo is dead but I dont want him spending money if thats not the problem. Any ideas on what I should do?

Something wierd going on, I can shut my windows XP down like normal, and I get all the way thru the shut down screens, the LCD screen goes blank, the keyboard lights go off, but the power supply in the computer remains on, powering the fans and lighting up my front panel fan control Assy. In order to turn off the power supply, I need to switch the switch on the back of the computer (power supply switch). Then, to turn if back on, I need to turn on my Power Supply switch, and open the case, and lightly touch/push the area near the CMOS battery, and without even touching the front panel power switch, the computer comes to life and I am able to load Windows XP and go about my bidness as normal! I SUSPECT this was caused from a lightning storm a few nights ago, it wasn't near me, but it caused the power to go out and come back on rapidly like three times. What gives?

Hey guys.

A few months ago i upgraded my PC by getting another HD7970 (had 1 R9 280x) and running crossfire. I also had to upgrade my power supply to support both the cards and i managed to find a really good deal on a PSU, a Seasonic X-series SS-1250XM Active PFC F3. I can't quite remember, but it was around that time that (i thought) my power button on my case had stopped working when the computer is off, although it will still shutdown the computer if it is on. I assumed it was because of my motherboard being so small, and the second graphics card pushing on where the case power button is plugged in.

Since then i have just been leaving my computer on 24/7. But when i do have to turn it on, i have to slowly flick the power switch on the PSU on and off, which after a few (or many) tries would turn on the computer. Today i finally went to troubleshoot what was wrong so i could buy a bigger motherboard or whatever and found it wasn't the power button on the case. Removing the second GPU so the power button can be plugged in properly didn't change anything, and the power/reset buttons on the actual motherboard also do not work.

I'm assuming now that it is the power supply, but i'm not too sure as i know the motherboard is still getting power when the computer is off (the Ethernet port lights up), and when the computer is on, there are no problems are all. I can play very demanding games for 6 hours straight, and leave the PC on for over a week without it ever turnin... Read more

Have an issue with my computer not turning on. A couple of days ago it shut down on me in the middle of web browsing. It would not turn back on. I noticed my power button LED light stayed lit. I completely unplugged the computer, and then plugged back in. The LED light was now off. I then pressed power and it turned on. After 10 minutes, the computer shut off again. LED light came back on. I waited til the next day to try again but was unsuccesful. I thought that I had blown my power supply. I replaced the power supply with a new one and the computer would still not turn on. At this point, I am puzzled by what it would be. I just so happened to have another MOBO, and I swapped the two MOBOs and still nothing. There is a small square light on the MOBOs themselves that come on when the power supply is connected. Not sure what it means.
Since swapping the MOBOs didnt do anything, I bought another CPU. After installing it, I get nothing.

I really need to get this fixed fast. Any suggestions? Why would the power LED light stay on. This is happening with both mobos.

When I turn off the computer, be it by pressing the power button or by the turn off option in the start menu, windows closes normally, the screen goes no signal, even the hard disk and power leds turn off but the fan in the power supply keeps spinning.

All I can do then is keep the power button pressed for a few seconds and finally the power supply stops, or press the reset button to start the computer again or click the power switch of the power supply in the back of the computer tower off and on (when clicked on again, the computer keeps turned off)

I had Windows XP in the same computer and it turned off normally. In fact, if I boot in Windows XP (it still is in another hard disk inside the computer), the turn off sequence works normally so it looks like a software problem, not hardware.

Hi,

Today I switched on my computer and it wouldn't turn on. I had a feeling that it could be something wrong with the power supply, so I took it out and connected it to another computer and it did not work on this other computer either! However, the motherboard light turns on when the power cable is connected to the power supply.

Would this mean that it is or is not the power supply that has broken?

I was thinking that it could be my front panel connectors that could be causing the problem but I'm not sure after I tested the power supply on the other computer and it wasn't working either.

Many thanks for your help.

Sorry this is so long. There's a condensed version in bold on the bottom with only the pertinent information.

I had posted this quite some time ago, before setting about trying to fix the problem on my own.

I turned my computer on today, and everything was running normally; I went about my business for a couple minutes until it just shut itself off. All the peripherals stayed on and acted like I had just performed a hard shutdown, so I'm pretty sure it's an issue with the computer itself.

If I leave it alone for a while, I can turn it back on, and it works fine until eventually shutting itself off again; the longer I leave it off, the longer it runs when I turn it on again.

I'm hoping this is enough information to provide some sort of diagnosis, as I don't really want to take it in for repairs on what seems like a rather simple problem. Thanks for any help.

edit: Update: Forget what I said above about being able to turn it on; it's completely shot now. I'm guessing the power supply's given out on me. Whenever I plug it in, what I'm guessing is the power supply starts emitting a somewhat faint yet very high-pitched, constant whine; not sure if this is new, or if I just started noticing it because I was taking a closer look at it. Anyway, if anyone disagrees with my conclusion, please let me know. Otherwise, I'll be replacing it pretty soon and hoping.Click to expand...

A:Computer won't turn on at all; Curious power supply behavior.

A lot of computers do that first burst of power, I can name 4 that I have had recently, and they are all happy and running (one in now my server), so this is not an issue. Does the computer not turn on at all? If it does not then I ran into one mahcine about a week ago that would not turn on at all, power supply was good, giving out 5 and 12, tested RAM, vid card, HDD's, CD ROM, mobo by itself, and reseated CPU. Nothing, this made me mad. So anyway I pulled the CMOS battery and boom, it worked, long story short it was a CPU recognition issue, dumb I know how it would not even turn on.

Tried pulling the CMOS battery on the new mobo? It is possible to get bad CPU's, I know a guy who went through 3 AMD's before he got one that worked, I do not think the issue is your power supply, it could be something is grounding out against the case or a bad CPU.

Hello! I have a common problem, but I can't seem to find the right answers! I am fairly experienced with PC hardware.

About 5 days ago,I noticed that a TON of dust was caked on my heat sink fan and dust had formed a nice layer on my motherboard and graphics card. I gently cleaned it out with canned air, and cleaned out the dust from my heat sink with a q tip, pretty much just collecting dust slowly. My PC was abnormally cool as it was, so after the clean up it was doing great.

You really have to completely disassemble the heat sink from the CPU in order to properly clean it. Q-Tips cannot reach where the dust lies next to the CPU, the most important area to clean. You were most likely too late, in doing this much needed cleaning and the CPU or the motherboard itself has fried

My computer will not turn on after an outlet cable that the computer power cord was connected to, seems to have broke and is giving partial electricity every now & then. I have been running tests and trying to figure out why it does not turn on for a full day now and here are the things I discovered:

- I opened up the power supply, and watched it while turning on the computer. I hear a spark-click and another, while the fan goes to spin but immidiatly is stopped, all in under a second. And that is the power on status, it is all it does. It seems as if it starts but then is being backfired.

- On the bottom board of the power supply, on GT3 and GT4 tiny cylinder-like fuses/things (that have a red line on one end and a black line on the other), spark when I very slowly connect the computer to the outlet. Is that normal or is that an electrical leak over a fried part of the board?

- The LAN and interior light both light up when the computer is connected to the outlet, meaning the power supply is not dead? The light up green.


I do not know what to try or how to test for what. And surely do not know what is going on. My guess would be a broken fuse in the power supply if there is one?

There were other electronics connected to this damaged cable, all work perfectly fine, including the computer monitor, peakers, and subwoofer.

Oh and the computer is a Sony VAIO VGC-RA820G that I have had ever since it came out, 2-4 years?

Hello Forum,

Summary: Weird burning smell for 2 or 3 boots --> Doesn't turn on, no sounds or lights from comp --> replaced power supply --> worked for a few boots --> back to completely nonresponsive state 15 mins later (details follow....)

I do not know the system specs and I can't find them out without posting this issue at this time. It may not be that necessary to know the details but I can find out soon if necessary. Let's just say it is NOT a new computer - the motherboard is large - I could tell you the model in a later post - the processor is 1.x GHz, something like 512 MB RAM, I have 2 HDs. I am running Win XP.

Old Power supply: Was pretty old, up to 10 years old but maybe a few years younger (300 or 350 W). I haven't seen the computer much for 3 years since I started using and it was upgraded in the meantime.

One day I turned on my computer and shortly afterwards the room started smelling like burning metal/rubber or something acridly foul. Opened the case and nothing seemed to be boiling or noticeably hot, though I didn't really touch around. The only thing that was reasonably warm was the P/S. I thought I noticed the smell coming from it but it was only slightly smellier in that area, at most. Didn't add anything special or change anything in comp recently beforehand. Played loud music on in the night before but the speakers have their own power supply.

So I decided to replace the P/S - I purchased an hec HP485D 485W ... Read more

I have a Compaq Presario, Windows Vista Basic, around 3 gigs of RAM.

I recently rearranged my room, and when I went to go plug everything back in for my computer, the power supply light started to flicker when it was fine the day before.
I don't remember this ever happening before; it's still green, it just flickers rapidly and I can hear it.
I thought it was a temporary thing, but my power button is completely unresponsive and it will not turn on.

I have had my power supply replaced twice prior, and I fear I may have accidentally surged my power supply when I plugged it back in.
I would like to know if this is the only cause, I have tried different outlets, and even checked to make sure that I didn't mix up my power supply cable with my monitor or printer, but the results are the same.
Even when I unplug any power source, the light flickers and gradually dies, as compared to going out immediately.

The last time I replaced my power supply was around October of 2009, due a faulty fan.
The time before, was October 2007, when the power supply just shorted out.

This time I am completely confused since it was working the day prior, and wonder if my moving it would have caused something. It seems so unlikely, but due to my bad history with power supplies, I am prone to assume it is the same problem.
But if anyone has any other suggestions, please help.

Thank you for your time.

My sister-in-law has an eMachine that she turned off and unplugged before leaving for vacation. A week later she returned and plugged it back in only to find it won't turn on. I don't know much about this pc other than it's a tower and about 3 or so years old. I figured it was probably the PSU (power supply) but wanted to verify as many things as possible. Basically, there is a green light on the back of the pc (on the PSU) that will flashes on and off when you try to turn on the computer. The PSU fan doesn't spin and nothing else makes any attempt to turn...just dead.

I pulled all the power connectors and jumpered the power switch pins (15-16), this gave me a solid green light on the PSU and the fan spun normally. I tested with a voltmeter and got the proper voltage on all the pins. I am thinking that this probably rules out the PSU but not 100% as something could be 'pulling it down'???

Any ideas on what else to look at? I hate to buy a PSU when it appears this one is ok. That pretty much leaves the MoBo and/or CPU. I've pulled all the cards and memory trying to get it to do anything and nothing affects it. I suspect there is something wrong with the MoBo but don't know how to verify that.

Any help or advice is appreciated. Thanks!

If you turn it off and try to boot it up it will turn off after the windows logo. note: I just put a new motherboard in this computer about a week and half ago.

We got a Compaq Presario S6500NX from a friend who had upgraded to another computer and we can't get it to work. It ran fine before he brought it to us, however, once we got it here and tried to power it up it wouldn't start at all.

On the power supply in the back the green light blinks and clicks rapidly when the cord is plugged in, and pressing the power button does nothing at all.

Interestingly, a few minutes ago I took it out of storage, (we got the computer months ago and gave up when we couldn't get it running) plugged it in by itself and it powered up just fine, the fan turned on and everything! So I opened it up and cleaned out some of the dust (I didn't have it plugged into a monitor or anything, I just wanted to see if it was still doing the same thing it had months ago) and, lo and behold, when I tried to turn it on again with everything plugged in, I got the blinking/clicking green light and no power up.

What could be the problem here? I know the whole thing isn't totally shot because it DID power up just fine a few minutes ago. But now we're back to the blinking clicking light (instead of the steady green glow that usually happens when the power supply cord is plugged in). It leads me to believe that something's loose, but I don't dare mess with the power supply box unless I know what I'm doing...

Another question is, if the power supply isn't fixable, would it be possible to replace it with the power supply ... Read more

I have a Dell 8600 about two years old. When I plug in the AC adapter, it intermittently fades to the battery as though the plug was pulled out (its not) and of course the screen fades in an out when every time it swithces--it does it every 30 to 60 seconds or so. I switched to a different AC adapter (I have a Dell 600M with the same AC adapter)-same thing so I know it is something internally. Any ideas?

This is my first post on the community and im having trouble upgrading my power supply. I recently purchased an EVGA 400w psu with a standard 20+4 pin atx connector. The lenovo board only supports a 14 pin connection with a 4 pin cpu so i also purchased a 20 to 14 pin adapter for it but have not had any luck getting the computer to boot with the new power supply. i know the problem lies with the connection to the motherboard because it booted properly with the original psu. So my question is: what adjustments need to be made in order to get the proper connection from the power supply, to the adapter, to the board?

Hi everyone, I need some suggestion with my problem. I am facing this problem from nearly a month. The problem is that sometime my laptop does not charge the battery even if it is pluged in. During those time i can only use my laptop untill my battery charge lasts. Which is normally 2 to 4 hour depending on the nature of the work. The only solution to fix this problem is to remove the battery and replacing it and hope for the best. Sometimes just one time doing this solves the problem and battery starts to charge again. However, sometime the process (bettery removal and reattachment) have to be done 5 to 6 time to do the trick. Please also note that if i remove the battery and directly connect the charger there is no problem and i can work. But here we face very frequent power cut so this process is not very benificial.  I believe something is loose in the battery compartment and thats why the bettery does not charge sometime and does sometime. Please let me know what i can do to fix the problem. The laptop is under warrenty but i am not sure if this kind of problem is covered under warrenty.  With regardsGKS

A:Power supply problem in lenovo B40-70

This may be due to a loose connection on the battery, or on the socket it locks into.  Either way - if under warranty I would suggest calling the support line and getting it fixed ASAP... That is the only way to be sure.
 
Good luck.

After finding out this pc has a low end graphics card i wanted to upgrade it, but as soon as i found out it had a 250 watt power supply, i started asking around on the internet to see if i could use a standard power supply, but i turns out i can't do that since this desktop requires a proprietary power supply. Could i just order a 500w proprietary power supply from lenovo?

Hello: Just received a beautiful W530 Laptop - love the T and W versions of this machines. However, with such a large power requirement, want to make sure that I will be able to run and charge the W530 on United Airlines, American Airlines, etc., using the supplied 170 W Power supply...  Please confirm your experience that this will work. Otherwise, using this laptop on long haul flights will not work.

I've recently inherited a lovely Y70-70 touch from my father, and have restored it to factory settings recently. However I'm having issues at the moment where it shuts down instantly at random times when not plugged in. Checking the system logs in the event viewer I see the following Critical message: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. Generally online help seems to suggest this is a power supply issue. Have I got a duff battery in here? Are there further diagnostics I can run? Unfortunately I'm out of warranty so keen to solve this myself!

My kids related a problem on the "kids computer", eMachine T2040 running XP. They related the computer CPU seemed to get very hot and got a funny, burning smell. Oh well, let's keep using it and see what happens. The power abruptly shut off and then they brought this to my attention.

I pulled out the power supply and found a fragged cooling fan and glue like substance oozing from one of the components. I bought a new powersupply and everything appeared to come back to life. Except the built in sound card and CD Rom now longer work. I rechecked the cord connections for data and power and they seem fine. The device manager shows yellow exclamation points next to sound card and CD rom drivers. Uninstalling them and re-installing them kills some time but has no resolution.

Question: could the high temp and sudden shutdown adversely affected and damaged the BIOS chip (where I presume the driver info is stored?)

A:Dead power supply and BIOS

The driver info is stored on the hard drive though.
You could check on the BIOS to make sure there is nothing disabling the devices, as the power supply failure could have caused problems.

You have to consider that the power supply failure could have actually damaged the devices or the motherboard though, as a prime cause.

At home, I am using a Docking station (ThinkPad Mini Dock Series 3) which has a different power demand than the W520. The docking station works properly but does NOT charge the laptop. So, I plugged in a spare charger-plug directly into the laptop but it will not charge. My logical guess is that the docking power plug is over-riding the laptop plug. Is there a way around this so that I won't lose power while working from home using the docking station?

A:Lenovo W520 Docking Power Supply

I was recommended to purchase 135Watt charger for the dock station. I received it last night and when I went to dock my laptop, I started smelling something burning. THe laptop won't boot up. The fingerprint reader, microphone and CapLok keys are lit but it will not boot.

Anyone?

Hello everyone, I just wanted to ask if this PSU: http://www.amazon.co.uk/Corsair-CP-9020015-UK-CX750-Builder-Bronze/dp/B008RJZR40/ref=sr_1_1?s=comput... Would work out with my Lenovo H530s (I know due to the size that It'll need to be stored outside the case, and I know that I'll need to buy a 24 to 14 pin adapater to be able to use the main power cable from the PSU to the motherboard). I'd just like to ask that taking all of the above into account, will the new PSU work? Is there anything else I should know?  - Thanks!

A:Power supply change (Lenovo H530s)

Hi Daniel778 
 
Greetings. 
 
I was waiting for other members that my have used the Corsair ATX that you are planning. 
As it is still an ATX and the bulk would still not fit your chassis if you are not considering atx chassis. 
Seen your previous post and maybe this article can also provide you additional information on your plan of upgrade considering both size and pin. 
 
 
Update us what would work best for you. 
 
Regards

I bought this product in the beginning of the year and have been loving it since, but I feel it needs a bit more "umph". Are these desktops upgradeable? If so, would it be possible to replace the current power supply it has, with a stronger one? Also, would installing a new graphics card be possible with this desktop? 90BG003JUS this is the model number of my desktop, http://www.bestbuy.com/site/lenovo-desktop-amd-a10-series-12gb-memory-2tb-hard-drive-black/4362103.p... The link above is also the same desktop.  I've been searching for a good few days, but can't seem to find a straight answer  Any help would be GREATLY appreiciated!

Basically as long you have the square shaped plug head and it fits in the power port then it is okay. I use 45 watts, 65 watts, and 90 watts adapter on the Helix.
