Computer Fails to Resume After Sleep

[Goons]

I know there are far too many of these threads out there and I have attempted many times over the past various fixes to no avail so alas, here I am. Figured it would be much easier to start from scratch so here goes:


My PC fails to resume after sleeping. I tell it to sleep fine, when I try to resume it from sleep the power lights flash up and the fans start spinning but only for a second before stopping completely. Usually it takes at least one or two attempts of starting the PC normally (via the power button on the PC as opposed to mouse/keyboard) before it will actually start properly as opposed to simply powering on for a second then off. However, when it does start again, it starts as if it's resuming from hibernation - i.e. the desktop will return to its previous state when I attempted to sleep etc etc.


Any help or advice on where to begin would be fantastic

Welcome to the Seven Forums.

Make sure that your video drivers are updated - they impact the sleep/hibernate functions.

Temporarily turn off sleep and hybrid sleep per this tutorial:
http://www.sevenforums.com/tutorials/22867-windows-does-not-start-after-sleep.html

Restart the computer and set it to hibernate after a short time.
Let it go into hibernation by itself.
Did it come out of hibernation correctly?

Now try the sleep option (leave the hybrid sleep turned off).

If what UsernameIssues suggests doesn't resolve the issue.


Turn off hibernation

1. Open an elevated command prompt (Start Menu->Accessories->Command Prompt (right click, run as admin...)
2. type the following commands
   powercfg - h off
   exit
3. Reboot your machine

Set the sleep timer in power options to 2 min
Let the machine sleep and see how it behaves

Turn hibernation back on using this command in an elevated Command Prompt
powercgf -h on

Reboot
Let the machine sleep

If all is well, reset the sleep timer to your preference.

Work through the Sleep Mode Problems - Vista Forums

Update your video driver, roll back if necessary, try another driver until Sleep works. Set Power Options>Balanced Plan>Advanced Plan settings timer to 1 minute Sleep, 2 minutes Hibernate for troubleshooting purposes.

Updated BIOS,
Updated GPU Driver,


Tried all manner of combinations of having hybrid sleep on/off, hibernating, hibernation on/off etc and still no luck. Also, I doubt it's a GPU driver issue since I've always had this problem. Moreover, when restarting, after the first initial second-long power up after sleeping/hibernating; the DRAM LED lights up on my mobo before powering off. When it does finally power up properly the boot_device LED lights up....


Not sure if that's any help or not.

What is the ASCAPI Sleep state setting in BIOS setup?

 

[Goons]

Where do I find that? Unless I have missed it somehow I can't seem to find it for the life of me.. and googling it hasn't helped either :S

 

[gregrocker]

It might be called something else, but the settings are normally S1, S2 or S3. You want S3. Not all BIOS have it.

 

[Goons]

Nope can't find anything that has those options =/

 

[gregrocker]

Have you installed all Important and Optional Windows Updates after enabling Automatically deliver drivers via Windows Update (Step 3)? Do that now.

Then if prob persists try another Display driver. The correct answer to this suggestion is not "I don't think its the Display driver." This is the top tech forums on the web. Please cooperate if you want our help.

If you have the latest Display driver, then try the one previous to it, even Vista if necessary.

 

[Goons]

I install all important and optional updates for Windows (other than bing desktop crap).

As for the display driver; it's just that I've tried a lot of different drivers, even beta drivers however it never gets passed the instant lights on power on to instantly power off. Could that be caused by GPU drivers? I never get to see anything on the screen and it's always the boot device LED that lights up on my mobo....

I don't mean to be arrogant/disrespectful or even uncooperative, I just don't understand why it could still be the graphics driver ^^

 

[gregrocker]

Because it's almost always the Display driver.

Confirm you've tried everything else for Sleep Mode Problems - Vista Forums.

Let's see if we can get Hibernate to work: Hibernate - Enable or Disable - Windows 7 Forums

Then choose Balanced Power Options, Advanced Settings> Set Sleep to 1 min, Hibernate to 2 minutes, save.

Reboot to see what happens.

Tried sleeping and resuming after booting up in 'diagnostic mode' and disabling hibernate; this time, when it went to sleep... the lights didn't turn off or the fans but the screen went blank and it just stayed that way. I left it for ~15mins and nothing happened, had to do a cold reboot to get it back =/

Tried setting it to hibernate after 5 mins after disabling sleep and rebooting in diagnostic mode but the same original thing happened; lights turned on and fans spun up for a second then shut down again.

I'll try getting it to hibernate with 'balanced power options' soon (instead of the high power option ive been using)

Try to get driver updates from your pc maker and not windows, since they can be different, and that is crucial.
Also in my experience, the ASCAPI Sleep state setting in BIOS setup does not always show S3, but sleep should still work.

 

[gregrocker]

I did not suggest trying one or the other Hibernate or Sleep, but both. Try again and follow the suggested steps.

Balanced plan may help.

Use the drivers provided by Win7 first (this is not XP) and then if those don't work import the latest Display driver from the PC or display adapter's Support Downloads webpage. If that fails try an older driver working backward.

Did it ever work correctly? Find that driver.

 

[Goons]

My apologies, I meant to say that I did try the sleep then hibernate combo;

I've noticed now (or at least it does it now) that after instantly powering off after I try to resume it from sleep, the next time it boots, it boots with a black screen with a blinking underscore. As for trying the default windows 7 drivers for my GPU is there any special program I should use to remove the old drivers or is just a regular uninstall okay? I have an Nvidia GTX 560ti but I do know AMD drivers are an absolute pain in the arse to fix/update/remove etc....

 

[gregrocker]

Just uninstall the old drivers in Control Panel and device Manager, then install the latest. Run Windows UPdate first to see if they provide one under IMportant or Optional after enabling Automatically deliver drivers via Windows Update (Step 3)

Most sleep and hibernation problems can be fixed by doing the following:-

Open a command prompt as administrator.
At the command prompt, type powercfg.exe /hibernate off, and then press Enter.

Restart your system.
Now go back to command prompt (as admin).
At the command prompt, type powercfg.exe /hibernate on, and then press Enter. (that is a space between exe and /)

This should resolve the problem whereby a computer will not resume from sleep or hibernation.
