How to fix a computer that wont come out of Sleep Mode 94


Has your Windows 7 computer ever gone (or been put into) Sleep Mode and you’ve been unable to wake it up no matter what you did?

From all the posts I see on this subject it’s a common problem amongst Windows 7 users.

99% of the posts I read tell you how to “avoid” this problem happening but very few talked about How to Fix the problem.

Firstly, how do we know that the PC is stuck in sleep mode?

If your computer is stuck in Sleep-Mode you should be able to hear the computer fan, see the power light on or blink but your computer monitor will remain blank. If you do not hear any fan noise or see any buttons light up or your computer produces 1 or more beeps, you may have a hardware issue (something internally has broken) such as a faulty power supply, faulty memory or faulty motherboard.

So having determined that the PC is stuck in sleep mode, here are a number of things to try… plus the FIX that finally worked for us.

1) Move you mouse or hit the “spacebar”. If this does not work try each of the following in order.

2) Press the power button in for at least 30 seconds until the PC powers off. Wait 30 seconds and power up again.

3) Switch the PC off at the mains or pull the power cord out and wait at least 3 minutes before powering up.

4) Try another mouse and/or keyboard and repeat step 1.

5) When the PC starts to power up, try and get into the BIOS by holding down the “del”, “Esc” or “F1” button (the specific button for entering the BIOS differs between PC’s …. check your PC manual if you still have it.

6) Put an original Windows 7 CD/DVD into the optical drive (CD/DVD ROM) and boot up the PC (this will only work if your BIOS has been setup to try and boot on the optical disk first before trying the HDD) if you do not have a windows 7 CD/DVD, you can create a Ubuntu boot disk by following the instructions on this You Tube video.

Once you manage to start the PC using a bootable disk, there are a number of things you can do at a BIOS level (see step 5) to make sure your PC does not go into sleep mode (see the Power settings).

If all these things fail, try the following which worked for us.

IMG_1666A) Leaving the power switched on, carefully take the side or back off the PC to expose the motherboard and RAM memory chips (seen here as long blue blades) making sure you do not touch any of the internals.


B) Look for a light on the motherboard and for fan activity to make sure there is power reaching the mother board and RAM chips. If we see activity, we can assume the PC is in sleep mode.


C) Remove the power cord and wait until all activity stops



D) Remove one of the RAM memory chips (coloured blue in this example, but often just bare and uncovered). Apply pressure as shown on the white toggle on both sides of the chips and they will ease out. Do not use excessive force.



E) Carefully remove the RAM memory set from the case.


F) Re-apply the power cord and switch on the PC.



G) If the computer has woken up you should start windows or at least show the BIOS screen. If you manage to get into windows goto “control panel” from the start menu and find the “Power” settings


H) Change the power setting and choose “Never” in the sleep options.

This solution worked for us but is not guaranteed to work in every case, so only use this as a LAST option if all else fails. The only side-effect we found was that we had to reset the Date and time.

      You should not still be using Windows XP. Support expired in April 2014, you are at serious risk of viruses and virus infection if you continue to use it on the Internet. Please purchase another PC using Windows 7 or 8 immediately.

    Hello. My pc has two network adapter (on-board and internal card). When
    I remove internal card, Windows Won’t Resume or wake up from sleep.
    I removed its driver but doesn’t work. Please help me.

  • Gene Millsaps

    In addition to my earlier advisory, I have more experience to share, on my Win7/64 Pro PC.
    (Warning, Also: In addition to webpage advice, we apparently need to enter a Maximum size, greater than the Initial size, click Set. Then, click thru Oks.)
    Re install your video card driver.
    (On my PC: Using Computer .. Device manager .. Display Adapter .. Rt-click .. Update Driver software .. on web .. says we’re up to date. Hopefully, no re-install is needed.)
    Allow Restart.

    I have a problem with my laptop. whenever i start my pc, after the “Windows Start screen” my computer screen goes to black. It won’t respond to anything the fan still goes and the power is still on. yet it’s like it’s turned off. I found out the reason for the problem, and it got something to do with my graphic card Driver. i got and AMD 6200M. and every time i download the latest version of AMD catalyst the problem comes again. i have tried to download an earlier version of AMD catalyst. i’ve tried reinstalling the laptop but nothing works. hope you can help me πŸ™‚

      We have also seen this problem caused through a Virus not allowing the PC or Laptop to start properly. Try downloading a rescue disc from AVG or AVIRA and boot the computer from these. They will get rid of viruses your normal anti-virus program cannot access.

    This is the most helpful and accurate information I have found on the hibernation/blackscreen issue. It was useful to use Unbuntu to boot up because it rules out hardware problems. However, adjusting the windows settings or the windows bios, or simply launching windows from inside Unbuntu? That is a many step process apparently involving command line code… so instead of a solution I am now looking at a project and hours of hard work.

    • IT Guy Post author

      Try forcing a reset by holding down the “CTRL” key when turning it on. Do a google search on your computer model to find out how to boot into “safe” mode. Windows 8 PC’s are much more difficult to reset.

  • Kenny Taylor

    When I turn on my computer the power button lights up and the rest of the lights in my computer flash and on my screen it just says entering sleep mode then goes black, there is no start up screen or anything

    ps thank you..!!

  • PROFA25

    If anybody is using a desktop with a manual shut off switch in the back. Like a Corsair power supply or other brand, then turn on your computer with the front button, or top. then turn it off from the back, turn back on switch, then push your power button in….Should solve your problem. If not do what IT GUY says..

  • randy frickey

    hi i have this computer that is in sleep mode and i don;t know what is on it yet and i just got it like that and i need help to get it working

  • Tom

    I had the same problem, the PC would not start after someone by accident pressed the sleep button.
    I tried all of the above with no luck.
    Then finally I disconnected the PC from the mains and removed the backup battery from the mother board for 3 minutes, then after that I could restart the PC. Only thing I had to configure afterwards was date and time in the bios + my preferred boot sequence.

  • p shiva

    Help me!.i had d same prblm kept my pc in sleep mode and its not starting now..i tried removing the ram but of no use..the fans are running but the led on d front does not blink..pls help me.

    • John Kirkby Post author

      Try another monitor or if a laptop plug a monitor in and see if you get a picture. Also try booting up using a Windows CD or a Ubuntu CD such as a Rescue Disk or any of the other techniques discussed here

  • efi

    i took out the RAM card, turned it on – and it really did get out of sleep mode, however – when i put the ram card back in – it’s again in sleep mode! so now i’m with 2GB RAM instead of 4GB. please help.

  • Andrew

    I had to move to the remove all chip set and small battery that finally got somewhere but as soon as I turn the computer on it is emitting this loud constant screeching. The same noise that started this whole problem actually when the computer locked.

  • cle

    Thank you! You are the only site that gave me a solution if I couldn’t get to my control panel because… my computer was stuck in safe mode!

    The funny thing is a fix computers for other people but can’t seem to know the problem of my own computer which is driving me crazy , so here is the story , i built this computer from spare parts got the motherboard seperatly it was a gigabyte ,then bought cpu i7 3rd gen and ram kingston 16gb , i first installed windows 7 with 3 hdds , 1 is main and two were RAID mirrored incase something goes wrong and i dont have to lose my data , i kept the pc in standby mode everytime because im too laZy to turn it on and wait so it goes to sleep and when i click mouse or keyboard it wakes up , one day i try to turn it on ans ops boot manager missing , which is fine i have seen it million times and actually fixed it , i tried everything from disck repair , boot repair , build boot manager , la la la all the available fixes , nope nothing , then i thought maybe its the RAID that is causing it so i removed the raid hdds nope same thing , funny thing is i tried to get the data from the RAID HDD and couldnt even cloning data recovery softwares , nope, then i cursed the whole computer IT industry and reinstalled windows 8.1 and removed the raid and kept it normal which is 1 main hdd and 2 extra ones , after a while same thing happened again and luckly this time i didnt lose my data , so i was like i think its the main hdd that have this sleep issue , took it off and got a SSD and in my mind thought yep this is the solution no more scratched disks ans slow boot time and corrupted boot files . And upgraded my windows to 10 , i was so happy everything was super fast and amazing , so i kep the same thing turn off my computer using sleep . I come back from work today and find out my pc is not waking up by mouse or keyboard so i turn it on by power button and ops pc ran into a problem cant boot , fix startup nope , then i went to refresh pc there was no option only reset and i kept my files but lost 3 days worth of installed programs and shit . So now i curse my pc because i thing its either the motherf board or the power supply causing this shit or the ram ? Or wat the hell is going on its driving me nuts

  • Phil

    Wow it happened to me I thought my monitor was dead ,but I just went
    ( ctrl alt del ) and presto then cancelled out of task manager good to go

  • Melissa

    Thanks heaps. This saved me a trip to the Computer store and an expensive bill. I turned PC off manually and started holding down F1. Windows loaded normally and I immediately changed the sleep setting in control panel. Fingers crossed this doesn’t happen again but at least I know what to do if it does πŸ˜‰

  • Allyn R

    Turning off sleep mode in the power settings is pretty obvious but the problem with that is sleep mode should work regardless. Why have a feature of an OS if the damn thing don’t work?

  • Kirsty Walton


    I’ve just purchased a refurbished computer running windows 7. The previous computer was replaced due to the monitor no longer recognising the monitor being plugged in, the PCU was also overheating.

    When setting up my new computer, I plugged all the same components in that was used on my last computer, but all that keeps coming up on the monitor is that it cant find a computer and to check the cables. I have replaced the monitor cable just in case it was that, and the same thing is happening. I took a monitor from another computer in the house that I know is working fine, and this one goes straight into sleep mode, and no matter what I press on my keyboard or clicking/moving the mouse does not work.

    The computer sounds like it is booting up normally. All the correct lights etc are on, but it has baffled me with 2 different monitors having issues.

    Any help would be greatly appreciated!!!


  • Simon

    Problem: When ordering sleep in Windows 7 my screen would go black but my computer would not sleep (fan still running). And then it was impossible to wake it up again (pressing keyboard, mouse, power button, nothing worked). The only solution was to cut the power and restart. Very annoying!

    Solution: I had two screens, setting them to “duplicate these displays” is what caused the problem. Changed to “extend these screens” and now my computer enter and exit sleep mode without problem. (right click desktop —> personalize —> display —-> change display settings —-> select “extend these screens” in the drop down).

    Writing here because I spent hours googling without finding the solution.

  • Pete

    I found that it was chrome that was making my monitor go into sleep mode seems it is not compatible with windows 7. After removing it I have had no problems since,maybe it will work for you if you have this problem.


  • Sab Bautista

    Hi. I had also put my pc on sleep mode then when i came back, i’ve been moving the mouse and typing on the keyboard but the monitor remains blank. So i decided to switch the power off. When i turn it back on, the cpu runs but still the monitor is blank. I did the instructions here in your post but nothing happened. What should I do?

  • joe bloggs

    Are you crazy?
    I am not going to pay any money to anyone to be able to switch on my computer.
    If the wort comes to the worst, I will go back to my old computer that has old faithful, Windows xp

  • Olivier

    Oh shit! Nothing else had worked for me, tried so many websites today. Taking out the RAM memory chip finally took my PC out of sleep mode. Thank you so much!

  • temitope

  • Tara

    I followed all the steps and my computer still won’t come out of sleep mode the fan is running really hard and the screen won’t turn on

    • John Kirkby Post author

      Try connecting an external monitor. However, I feel that just powering it down fully by holding in the power button for 30 seconds may get it to boot properly. (or pull the cord out of the wall), if you still see nothing as you hear it boot, it maybe the video card that has failed and needs replacing

  • Joe Bantol Bestman

    My DELL CPU get in standby. The power button shows steady (not blinking) amber. Pressing the reset button makes the power button alternate between green and amber, and the CD drive light lights as though trying to read a CD. I’ve tried turning the computer on with a bootable CD installed, and the CD drive starts to spin, but nothing is read and eventually winds down. The monitor yellow light is on continuously, and the screen is always dark. I’ve tried booting from a startup floppy, but the computer never tries to boot from the floppy. I can shut down by holding the power button in for 5 seconds. When I turn the computer back on, it immediately goes to the amber light on the power button, and tries the CD drive as described above. The standby light on the motherboard is always on (yellow).

  • SylArt

    please I need help, my Toshiba satellite froze so I pressed my power button and my system went to sleep. since then I can’t power it or boot it because it can’t come out of hibernation mode. I tried holding the power button for 30 sec still no show. my battery is inbuilt
