    Eeek! My Pc keeps falling asleep!?! 7th Nov 18 at 1:07 AM
    Hi all

    I have a pretty old Acer aspire m7200 pc. Today my step dad switched off the electric to sort some sockets out in the house and my pc was on (in sleep mode). This evening I've powered it back on, but now it's randomly going into sleep mode, sometimes I can even get it out of sleep and it will instantly go back into sleep again. And just now I've rebooted it and it was going into sleep mode whilst booting!

    Any ideas? I might try see if I can get to go back to a restore point.

    Edit: Its doing system restore right now, so far it's staying awake. Fingers crossed.

    Edit2: Its still in system restore (started it around 1am, it's now almost 3..), been on "system restore is restoring the registry" for aaages. I'm gonna just go bad and leave it and see what it's doing in the morning. Main thing us its still awake haha.

    bex88, the easiest way (if you are a techie) us to boot off usb that has a live version of linux mint or Manjaro on it, and if it still happens running this then you know it is the laptop, rather than windows.

    if it is windows, the often power & sleep (win 10) is the main culprit

    It would be very helpful if you could check the event log (Event Viewer) to see what initiates the sleep mode.

    If it was a laptop, and it went into sleep mode while you were using it (for example), it was possible that the magnet that senses when the lid is closed got damaged or misplaced, but since it's a desktop computer, there are no sensors.

    So it could either be: A) a program that initiates the sleep mode (and you should be able to find the culprit in the event log); B) a faulty/stuck power button or a stuck function key on the keyboard.

    Hi again all, well the system restore didn't work, just got stuck at the same bit for near 3 hours so just turned it off and back on. It loaded up and said system restore had failed but nothing was effected. The pc then worked fine all yesterday. Today I've gone back on it (woke it up from sleep just now) and it was doing it again. Couldn't even get to log in, as soon as i woke it up again and I saw the login screen it would sleep again.

    I held power button to turn it off. It started back up, did it again in middle of booting up and now I've managed to log on and it's ok at the min. I'll have a look at how to do the event log thing.

    Oh and yep it's a desktop, used to be Vista but updated it to 10 last year as many programs were not being supported on vista anymore and some wouldn't update.

    Edit: Ok well I have the event viewer up but I have no idea what I'm looking at on it XD

    Edit2: So I've looked it up and found I'm looking for Event ID 42. Kernel - Power. I've had a look and the most say:

    "The system is entering sleep.
    Sleep Reason: Button or Lid"

    and the odd couple say:

    "The system is entering sleep.
    Sleep Reason: Application API"

    Does windows still have a safe mode ? I'd probably try booting into that to see if the same symptom appears. If it stops, that might point to misbehaviour of some loaded code. If it persists, might be something more fundamental.

    Though clearly since it's an intermittent problem, it would hard to be sure.

    Safe mode :- https://support.microsoft.com/en-gb/help/12376/windows-10-start-your-pc-in-safe-mode
    I'd probably not mess around and do an inplace repair/upgrade with 1803 from media (keeeping data AND apps). Could be a dodgy desktop power supply (although if it was ok before the accidental switch off should be ok now).

    Just got back from work. Trying to get on to PC again and it's turning on and off (sleep) constantly. Struggling to even log in. If I can I will try get to do the power-cfg thing. Will try boot into safe mode also.

    Edit: Still Really struggling to stay logged on. Just keeps turning off (sleeping) I don't know what to do. I've tried unplugged power lead for 30 secs and putting it back in. Unplugged graphics card cable, back in. Sometimes it's even turning itself on without me even moving the mouse or pressing the button or keyboard. It's just gone crazy.

    Not even bring up the login pin bit now. When i click the background just make a bbbblling sound then turns off again.

    I can make it go into the setup on boot and it's absolutely fine in that but as soon as it goes to load up windows it plays up.

    Well I'm assuming it's sleep, as it does the exact same thing as when I click to put it into sleep. Fan speeds up a sec then it all stops and screen goes off. Then any mouse movement or keyboard touch or press of power button brings it back on again.

    Yep it's the M7200.
    It has AMD Phenom II X4 Quad processor.
    ATI Radeon HD4850
    4GB DDR2
    The Power supply was replaced roughly 6-7 years ago when the original one stopped working. It has a Power X3 Pro edition in it now.

    Strangely, perhaps a coincidence, ive unplugged the the external hdd that's connect via usb and this time I'm logged in and stayed on at the mo... hmm

    Here's what it says in the cmd for powercfg -a

    "The following sleep states are available on this system:
    Standby (S3)
    Hibernate
    Hybrid Sleep
    Fast Startup

    The following sleep states are not available on this system:
    Standby (S1)
    The system firmware does not support this standby state.

    Standby (S2)
    The system firmware does not support this standby state.

    Standby (S0 Low Power Idle)
    The system firmware does not support this standby state."

    Windows 10?

    type Start > type Power & sleep settings, make everything under the settings to Never

    also go to and adminstrative dos prompt, in there type
    powercfg /ENERGY
    Wait and it will probably tell you it created the file in C:\WINDOWS\system-thirty-two\energy-report.html and you need to move this to somewhere accessible like desktop, and open the file with your browser
    ... and what do you get?

    It's Windows 10 now but originally it was Vista. Bought it gotta be at least 10 years ago now as an A1 condition (box opened) from Acer direct.

    I've not plugged the external hdd back in as of yet but will try another USB port and see what it does and report back. So far it's not done the sleep issue since keeping that usb unplugged so maybe it might be something to do with it, but I shall see.

    I turned everything to 'never' now. There was only 'screen' and 'sleep' settings in there.

    The powercfg /ENERGY has given me:

    Energy efficiency problems were found.

    So it's randomly been working fine then tonight it's started doing it again. I literally can not log into it for more than a minute before it goes off, sometimes only after a few seconds. Comes on, then screen goes black 'no signal' fan or something sounds like it's spinning faster then stops and power light goes off. Move mouse or press on button, cones back on, then does same again.

    My display and computer sleep are both set to Never.

    I've unplugged everything from usb sockets and card reader, apart from my mouse receiver - which I've moved to different usbs.

    Edit: now it's just popped up with " we have an update for you..." I'm just restarting it now so will see what it does.

    Edit2: ok now it's working again... now I'm wondering of its some sort of update issue..

    I wonder if this could be 'hibernation' playing up? ... corrupt file maybe?

    The Hiberfil.sys hidden system file is located in the root folder of the drive where the operating system is installed. The Windows Kernel Power Manager reserves this file when you install Windows. The size of this file is approximately equal to how much random access memory (RAM) is installed on the computer.

    The computer uses the Hiberfil.sys file to store a copy of the system memory on the hard disk when the hybrid sleep setting is turned on. If this file is not present, the computer cannot hibernate.
    You can easily turn hibernation off ... (and back on again! ...) with these commands in a cmd window (with admin privileges)

    type powercfg.exe /hibernate off, and then press Enter ... that will destroy the current (maybe corrupt) hiberfil.sys file ...
    type powercfg.exe /hibernate on , and then press Enter ... that will rebuild a fresh hiberfil.sys file!

    more here .... https://support.microsoft.com/en-us/help/920730/how-to-disable-and-re-enable-hibernation-on-a-computer-that-is-running

    Worth trying anyway!

    OK so now we're getting somewhere.

    I think its actually shutting down because it is overheating, not because of any issue with Windows. Eventually they get to the point where they'll just fire up and instantly shut down. If the PC is a few years old chances are the heatsink is blocked up with fluff, if you smoke it could take less time to do that. You will need to take the lid off and find the CPU fan. That'll be on top of the heatsink which is likely to be full of fluff and dust. If you've a vacuum cleaner with a nozzle you can use a paintbrush to dislodge the fluff whilst sucking it away with the vacuum cleaner nozzle.

    It's driving me crazy. It's doing it again. I've tried to get to the cmd to try the hibernate thing but at the mo it goes off as soon as I log on.

    I've opened the case, I don't smoke and do usually give it a dust once or twice a year inside. I've taken the fan off the cpu bit and the fins don't look too bad at all but then I did only give that all a dust a few weeks ago when it first started doing it, thinking maybe it was dust causing a problem.

    https://www.dropbox.com/s/5ey7v36u60u81jt/20181214_015346.jpg?dl=0


    Just trying to figure out how that part comes off now, it's the black lever but not sure which way to manoeuvre it, feels stuff and don't want to break.it...

    Edit: ok so I've take the cooler off, was some dust under it but not too much. Cleaned that. Then took the graphics card out. Dusted that. Took the psu out. Dusted that. Pcs had chance to cool down all the while. Started it back up. Still doing it :'(

    Somethings going on because it's actually waking itself up after it goes off without me even moving the mouse. I noticed it had been doing this previously when I put it in sleep mode before bed, then randomly in the night it would wake itself up.

    The powercfg.exe /hibernate off did not work, it says unable to perform operation, unexpected error etc..

    Something I've seen before is the power button sticking and causing random shutdowns. Try turning the PC on then disconnecting the power button lead on the motherboard. If it stays on without the power button connected, then you may have found your problem.

    If is the power button sticking, you might be able to pop it out, clean the sticky edges and put it back in again. You could also try just a small squirt of WD40 to lubricate the power button.
