Power Turns Off Then On Again

Q: Power Turns Off Then On Again

Hello, and thank you to anyone who is reading this for your consideration. I have had a problem with my computer powering down and then restarting again. It did this 3 times before I swapped the power supply, thinking that was the culprit. However, it just did that again with the new power supply. My computer is, of course, not one with an 'off' switch, so it basically goes into standby when you turn it off. Could this be a faulty power button? Here are the specifications:

Hello everybody!
I have a Dell Inspiron 3847 with an i5 4440, 8 gb of ram, and 1 tb of hard drive. I purchased an evga 500 watt PSU and successfully installed it. My pc worked normally and everything was fine. I then purchased an evga 1060 sc and attempted at installing it into my pc. After installing it I started up my pc and it turned on. The fan for the gpu didn?t spin so I turned off my computer, opened the case, unplugged the 6 pin then plugged it back in. I turned on my pc again but it made an odd sound before the power button flashing orange then completely shutting off. Now every time I turn it on the light turns orange and the fans spin for a split second then they stop. Any assistance will be much appreciated...

When I attempt to turn on my computer the power light comes on and I hear the fans running but after a second or 2 the light goes off and the fans stop running, after a count of 2 the light comes on the fans start up again and the same thing happens again, on off on off I don?t have to touch the button the only way I get it to stop is pull the plug from the wall. I thought maybe it was a power supply issue so I replaced this with a new one but I got the same results. Does anyone have an ideas????   

A:Computer power issues ! turns on then off turns on then off ...

Dear Customer, Welcome to the HP Consumer Support forum. In order to isolate the issue, please try and perform few basic steps as follows: 1. Open the hood and ensure the 4 or 6-wire power supply cable is seated into the connector on the system board2. Check if a device is causing the problem by removing ALL attached devices (such as hard, diskette, or optical drives, and expansion cards).3. Power on the system.4. If the system enters the POST, then power off and replace one device at a time and repeat this procedure until failure occurs.5. Replace the device that is causing the failure.6. Continue adding devices one at a time to ensure all devices are functioning properly.7. Locate the header and jumper labeled CLR_CMOS8. Remove the jumper from pins 2 and 3.9. Place the jumper on pins 1 or 2.10. Put the jumper back on pins 2 or 311. Replace the access panel12. Reconnect all the disconnected devices one by one and then power on the unit and check if the issue persists. In case issue persists please get back to us and we would be glad to assist you. Hope this helps, for any further queries reply to the post and feel free to join us again. **Click the KUDOS star on left to say Thanks** Make it easier for other people to find solutions by marking a Reply 'Accept as Solution' if it solves your problem. Thank You,GR1Although I am an HP employee, I am speaking for myself and not for HP

Hi RanaHasssan
Thanks for writing to us. 
The power LED shouldn't turn on when battery is inserted. 
Please update the BIOS from our support.euro.dell.com --enter the tag#--submit--select drivers and downloads--choose the operating system and install the BIOS from the list.
Does it happen the same when you plug in the charger (without the battery)??
When did the issue start?

picked up this Packard Bell that the people said used to turn on by itself repeatedly. It now will not turn on at all. I plugged in a atx supply to it and punched the on switch and nothing. What else can I try??
 

A:turns on by self then no power

Well, first of all, are you sure it is a standard ATX? Some PBells didn't use standard wiring.

When you push power, you don't get lights, or fans spinning?

My computer regularly turns off all by itself. It could be anywhere from 3 miniutes to 3-4 hours for it to turn off by itself. When I unplug the computer power cord and plug it in again then the power turns on again but usually turns off again after a while. Why does my computer turn off by itself and how can I resolve this problem?
 

A:Power on computer turns off by itself very often

This could be caused by a component of your computer heating up and telling the computer to shut down to prevent over heating. Make sure the computer is clean on the inside first and foremost! I suggest finding a temperature monitoring program like MBM5 or speed fan so you can tell just how hot things are getting. Hope that helps! Give it a shot and tell us the results.

Hi,
Wondering if someone could shine a little light my way. My boyfriend has an emachine desktop W4682 and just tonight it has started giving me two problems.
First when turning on the pc the power light turns on and stays on, you can hear the fan humming but nothing else happens... no signal to the monitor. Something that I noticed was that the light for the dvd+-rw drive stayed on too. Thinking that maybe the dvd drive might be the problem, I opened the tower and disconnected the dvd drive. So far so good. The pc turned on and booted completely. After a couple of minutes of using the pc I started getting an error that said "power surge on hub port" and all I could do (after reading a few posts here and there) is turn off the usb alert on the advanced options.
For now I am able to use the pc but I'm worried that I might be causing it some permanent damage by leaving it as is. Best idea yet is to buy a better power supply? Anybody got a better one?

*Not expecting miracles here. I know of the little potential the emachines have*
 

A:Power light turns on but nothing else happens

G'day Myzteryh, these kinds of problems present difficult answers, quite obviously there is a malfunction of some type but what is the best course of action.
It is possible that some kind of malfunction has happened within the DVD combo or some other problem has affected the DVD combo but not knowing becomes difficult. The usb indication also is a consideration.
You could take it to a shop but they probably would not do more than what I am about to suggest.
It would probably be pertinent to obtain "Everest Home" off the net, (google it, Lavalys) this is an analysis program that can be helpful, remove any unneccessary USB stuff, load the Everest program, if you are able to, open it, then open the computer icon in it, then open the sensors section. This will show voltages and temperatures within the machine. If you could somehow copy and paste that page here would be nice, reallly what we are most interested in is the voltage readings, you can expect the table to show suggested readings on the left and actual readings on the right. I do feel you may find some way to achieve this without much problem and we may be able to work out what may be happening.
Do not leave the machine running for any period longer than neccessary at this time. (give it some thought)
If any of the twelve volt readings are above 14 Volts just switch it off and replace the power unit without any further testing.
There may be other ideas on how to address this problem.

Cheers, qldit.

Hello, my E5-511 screen crashes every time i power on the first time. The acer logo appears, then the screen goes black but the computer is still going. I have to hold the power button to turn it off and then turn it back on again to get it to work. I did a power drain (removed the battery and held the power button for 15 seconds to remove all stored power) and then it worked properly for about 36 hours and then right back to this same problem. As well, it never sleeps, it just shuts down all the time and then i have to go through this nonsense to get it powered on again.has anyone ever experienced anything like this before? thanks!!

My computer has been running amazingly untill about a week ago it started shutting off right in the middle of operation. When I would boot it back up Microsoft would do the "Send error report" thing and it would send me to a web page saying that it was a hardware problem but it didn't know what hardwear was failing. It gave me a list of possible:
If overclocking turn off (Which I was and did disable)
Check Prossesor (My AMD 64 X2 +4200 is brand new and appears to be working fine)
Over packed power strip (Not a problem)
And Power supply. ( I think this is the most likly but have no way of proving it. I'm running 4 Hard drives. 1 Floppy. 2 CD drives. PCIe graphics card. 2 180mm fans and 1 80mm. all on a 450w power supply. Is that too much for it to handle? and Yes it's all nessisary.)
 

A:Computer turns off as if power went out.

It also can depend on the quality of the power supply. A cheap PSU will say 450 W but this is a peak value, and is an unrealistic dream. If it is a name brand or one of high quality it will put out a constant 450w. Check the label on the PSU to see if it is 450 Peak power, or 450 Constant. If it is peak, I would be looking into getting a more powerful PSU. I personally like to buy quality PSUs. I have a Cooler Master True 550w and it has never given me a problem.

I just built a new i3 SB machine with a gigabit board. It was working fine for 3 dys put win 7 on it, but now all of a sudden it just shuts off as soon as i press the power button.

I took the board out and looked at it and i powered it on outside the case but it still does it. Everything looks kosher to me.

Could be a few issues, maybe the power button is getting stuck in and just powering down the machine.
Mobo or PSU might be defective.
What I would do is unplug all hardware and just use the bare minimum and see if it still powers down.

Why does my computer turn off by itself and how can I resolve this problem?
 

A:Power on computer turns off by itself

A few initial thoughts.

- How old is the PC? If it isn't that new have you ever cleaned it out inside?

It could be a heat related issue although I would of thought you would get a warning before shutdown (although not always). If the temperature reaches or exceeds the temperature set in the BIOS the system will shutdown to protect itself.

- If it runs for a while, then shuts off. When you turn it back on does it normally shutdown again after a very short time? Or can it run for ages again before turning off?

Well I'm sure you guys have read the whole "last night I turned off my computer, and the next morning my computer won't boot on." I have the same situation and found out that my power supply is the problem when I try powering on my pc with my old pc. Although when my psu is plugged in, a dim green light is on. I researched and found the paperclip test. I tried it and saw that the green light is bright and the fan turns on. So I'm guessing my psu is not fully dead (if that makes sense). What is wrong? Why will it not boot my computer althought an old psu does?

Hi! Yesterday, I turned my PC on from 1:00PM to 12:00AM. After that, I turned it on at 7:30AM, and after 4-5 hours of working, it turned itself off (directly, but the green LED on the case was still lighting until I kept my finger pressing on the Power button. Then the light was gone). After that, I opened it again, but after about 3 hours of continuous working, it stopped in the same way as before - with the green LED lighting. I left it for a couple of hours. Then turned it on again, but this time, after an hour of working, it stopped!
For knowledge, I faced this problem months ago, when I used to turn it on for 10 hours daily (for about a month)!

A:My PC Turns Itself off With the Green Power LED Lighting!!!!

An intermittent power issue? I would be inclined to suspect the power supply or motherboard being at fault, but it really could be a multitude of different things. First of all I would check to make sure all of the cables are properly secured. Also make sure your computer and display are plugged into a surge protector, this is important. If you know what your looking for open up the case and make sure that the ATX power plugs are secured properly and that there isn't too much dust in there, especially inside the heatsinks.

Do you get any kind of errors or slowdown in Windows before the computer crashes?

Hello,

I'm new here and have a problem with my laptop. It's a fairly old vaio about 2-3 years. It recently started to turn off randomly, no warnings, not even a BSOD. I have searched and non of the other computer shutting down problems have the same symptoms.

Let me explain. When plugged into the wall via the AC power adapter, when idling or waiting for games to load etc. it may choose to shut down unexpectedly. Now I've been having this problem for a couple of weeks now and when it's running on the battery, it's fine, it can run till the battery is empty without shutting down, this is bout 1 hour and 30 mins. If it was connected to the power adapter, it would certainly shut down much earlier than this.

Heres the weird bit. When connected to the wall via the AC power adapter, it will NOT shut down if a 3D application is running, this includes playing games. When there is nothing 3D to render, such as when games are loading or it is idling on the desktop, it will certainly shut down, randomly. Another thing is that it will also NOT shut down if running in safe mode. I have left it on safe mode for about 5 hours for a test and no shut downs. Only when in normal mode it will. I have also left a game running for around that long in normal mode and no shut downs. Now to prevent my computer from random shut downs when I am using it, I continuously run a 3D modeling program in the background. This defineately works as I have left my computer running for days like this and n... Read more

Hi,

I have a Dell Inspiron 530 (desktop) with Vista Home Premium. Until the other day, when I pushed the power button to start the PC, it turned blue and the PC went through the boot-up process. Now, it turns yellow and nothing happens unless I do more. So I push and hold the power button until it turns off. Then, I push the button a bit more strongly and it turns blue and boots.

My first thought was that the power switch for this 2008 PC is getting old and that I may become unable to boot at all. So I have decided to just let it go into sleep mode for now rather than turning it off for the day.

Any ideas on solving the yellow light issue?

I also tried creating a usb bios recovery as mentioned by HP and tried the windows logo + B button combination but still nothing has happened.I hold the windows logo + B, then turn on the computer. Nothing happens. I have tried holding them for different lengths of time, there's no beeps, no text on the screen, nothing.  Please help me out,What am I missing?

My roommate tried to "fix" his PC but god knows he doesn't know crap. The PC acts like it is going to turn on, but the light on the front of the tower does not light up, nor does the display. The light on the motherboard is solid green, and he is still able to charge a phone through the PC, so I'm guessing the power supply is good if it can do all of this. At this point I am at a loss because I'm normally very good with this stuff, any suggestions? and I don't believe it's the video card.

Ok so here is the problem. I really don't know when this started happening but it suddenly just did. Just a heads up, my laptop has not been through a heavy fall or anything like that. Sometimes the charging indicator light does not light up but the battery still shows as charging in windows. Its at 89% since the last 2 hours. As soon as i unplug the charger, the laptop just turns off and does not start without it. I can't even contact acer support since my laptop is not in warranty anymore ;/. I just did not notice it before because my laptop is usually plugged in on my desk. Please need help asap. Thx in advance

Hi

I reformatted my PC a few days ago and since then the monitor keeps shutting down randomly. The screen goes black and message 'no signal detected' appears then screen turns off, although power remains on (monitor power light turns to amber). The pc itself remains on and running - it doesn't shut down. I then have to shut down and turn pc back on manually.

Last night when watching a video file, screen blacked out and shut down. The audio of the video file also crashed so I assume it caused a problem to the pc? I'm not sure. If it didn't, surely the audio would continue.

The monitor is running of the onboard graphics card (motherboard) and bios setting is set as 'onboard VGA enabled' - my graphics card doesn't work and haven't had time to replace yet. My monitor has been running off the onboard VGA for a while now without any problems until I did the reformat.

I have checked cables and heating and can't find the problem. Please help!

Thanks

My IdeaPad just suddenly turned off while I was playing a game. AC adapter was plugged in is so I guess battery is fully charded.  When I press power button, the power led lights up. It doesn't blink or anything. It lights constantly. But nothing else happens. No sound or anything.  When I press and hold the power button the led turns off after a few seconds.  When I connect ac adaptor the ac led turns on (white). It doesn't blink or anything. I guess it means that the battery is full.  I've tried to hold the power button for a few seconds (as a lot of people suggest here) but it doesn't change a thing.  Please help me. This laptop is 8 months old. The battery is non removable.

I have an XPS13 that I wanted to get a spare power adapter for.  I purchased a used genuine Dell JT9DM on eBay.  Same model number as the original adapter.  If I plug the new adapter into the laptop and into the wall it charges the laptop.  If I remove the power connector from the laptop the green light on the power adapter goes out and will not turn back on unless you unplug it from the wall and then plug it back in.  The power adapter that came with the laptop does not do this, the green light stays on regardless of being connected to the laptop.
I figured the adapter I got on eBay was defective and purchased another.  It does the exact same thing.  So while I can charge the laptop battery with the two adapters, I have to unplug them from the wall every time I connect the adapter back into the laptop.  Is there some way to re-program the adapter to stay on all the time?

A:Power adapter turns itself off when unplugged from the laptop

Hi DAVEXS,
What is the exact system model? Have you purchased the adapter as designed for your region? 
There are certain adapters that are designed specifically based on the region / country.
Kindly advise the exact system model and country you reside in and a picture of the adapter pins, so we could review them.
Also, please click my DELL-username and write me a private conversation with the service tag and your contact details(Name and Email) for case records.
Let us know if you have any other queries.

When i try and connect the 4 prong power source to the motherboard, the fans and lights quickly flash and stop spinning after about 1/4 of a turn.
When i disconnect the 4prong power cable, and only leave the larger power cable in, the pc turns on like normal and stays on, but displays no picture on the monitor and also the mouse doesnt light up?
Am i right in thinking that the processor has broken? and that the pc needs the 4prong power source to function properly?
please help,
thanks
 

A:My pc only turns on when the main power is connected to the mobo.

You should have to have all of them plugged in. Did you miss another power connection on your mobo that gives power to the CPU?

Hi, My battery seems to hold a charge very well. However, the problem is when I try to move my laptop on battery power; it suddnely turns off. It also shuts down when jostled or bumped. The battery is great when the laptop is stationary. I noticed this problem when I move from one class to another: The Aspire V works great during class, but the moment I shut it and put it in my backpack it shurts down and I need to reboot it for the next class. The laptop is great when it is plugged in. This seems like a hardware issue but I don't know what to do. Thanks for your help!

Hello, I just finished re-assembling my computer after cleaning it up. When I try to boot it, the power LED turns on but the Wi-Fi & num lock LEDs don't. Pressing caps lock doesn't do anything, a hard reset didn't help either. I already tried booting with just the battery, just the AC adapter and both. Have I fried my motherboard?

A:HP Pavilion G7 Black Screen, only Power LED turns on

I re-assembled the computer and for some reason it works now? Not gonna complain.  TC

Basically what the title says. I have my power options for my monitor timeout set to never turn off. It's a desktop, and I think I can trace the problem to a certain program. I have Arcsoft Totalmedia Theatre installed for playing BluRay movies and when I run it, it changes the display options back to Windows Vista Basic. It would seem that the power option changes itself back after I close this program and Vista goes back to Aero mode.

Any ideas what I could do to fix this? I use the program a lot and I absolutely hate turning my monitors back on.
 

A:Vista turns off monitor even though power options are set to never

I would remove Arcsoft Total media Theatre, then reset Vista, defragment, and reboot, then reinstall ArcSoft TotalMedia Theatre, and see if it will behave next time.

A:Power turns on but no beeps or screen signal?

Hi broken_biker69,

I'm just wondering if this is something quite basic. Please try the following:

Remove the Power Adaptor
Remove the Battery
Remove any other external devices (ie USB devices)
Hold down the ON button for 30 seconds
Then put the Power Adaptor in ONLY
Turn on the Power at the wall (just in case!)
Turn on the computer

If that works please reply (to this thread)

I have an Averatec 3200 series laptop that has XP home edition,512MB DDR, 80GB HDD,AMD Athlon 2200+, when I turn the power on the blue power light comes on and i can hear the fan run but there is a series of three beeps and then silence and then keeps repeating the sequence of beeps until i just turn it off but the screen never lights up or comes on.
The last time that the laptop was on and working, while i was in the middle of an application, the screen had lines running across the screen (up & down) and the whole thing froze up and when i turned it off and then back on this is the problem i was having. Is there anything i can do to salvage this laptop or is gone? Thanks to anyone who can help me!!!

A:laptop power turns on but screen doesnt

Sounds like the laptop is not able to do the POST successfully. Try removing everything non-essential from the laptop (hard drive, optical drive, graphics card if it is not soldered onto the motherboard, etc.) and try powering it on. If that succeeds, add the additional components to the computer one by one until you isolate the one causing the POST to fail.

Hi,     As you mentioned latop turns on but nothing else happens, please turn off your laptop and turn the laptop on and keep tapping f11 key on keyboard now you must see recovery manager screen,select system restore on the list and select earlier date when your laptop was working fine and click finish at bottom once the laptop restarts you should be able to use without any problem, If not then check lights on caps and num lock whether it is blinking if yes then check how many times caps lock blink and reply back to this message, and if their no light blinking then you might have to reseat RAM and HDD even after reseat if still their is no display try connecting it to external monitor and check if their is no display then it should be problem with motherboard.  Thanks.ChetanI work on behalf of HPPlease click ?Accept as Solution ? on the post that solves your issue to help others find the solution.Click the KUDOS STAR on the left to say ?Thanks? for helping!
