Desktop reboots itself on sleep or hibernate

All we need is an easy explanation of the problem, so here it is.

I have been using an ASUS M2NPV-VM motherboard for main home desktop workstation, operating Windows Vista x64. This computer has right from day one not been able to enter hibernate or standby; after Windows performs its final actions and brings the machine down, it would automatically revive itself for a reboot.

Updating to the second latest BIOS (1201)has not helped (the latest BIOS revision would induce video refresh problems rendering it unusable). I have been reading related discussions on incidents similar to mine to no avail of a true workable solution. They appear to be more speculative guesses rather than actual knowledge on the inner workings of motherboard hardware.

Does anybody have any electronic engineering experience on PC energy-saving standards to provide a more informed opinion how to go about getting this to work?

More stories: this motherboard could not even reboot properly the first thing i used it. It was due to refresh rate of the onboard GPU, which had no influence on the sleep/hibernate issue here. But right now, i have been using an add-on PCI-E video card and disabled the onboard chipset. That has not changed the situation.

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

The problem is that your mouse or your keyboard automatically wakes up your computer when you want to put it in sleep. To disable this behaviour go to Device Manager, choose your mouse / keyboard and disable something like “This device can wake the computer up.” This worked for me. 🙂

Method 2

For me, it usually ends up being network devices and WOL, even when that feature is disabled in the BIOS.

In your device manager, make sure you uncheck “This device can wake the computer up” as KovBal said, for your network cards.

Method 3

  1. After updating BIOS load set up defaults from the BIOS menu
  2. Install the latest power management drivers from ASUS
  3. Make sure ACPI is set up correctly in the BIOS
  4. Check event viewer to see if there are any events that can be correlated to this problem
  5. Check under “System properties” -> “Startup and Recovery” that it does not automatically restart. In case you have something that brakes during hibernation/standby that causes an automatic reboot.

I hope you manage to fix it!

Method 4

I have had similar problems on machines myself. It may be worth checking in the BIOS that all the ‘Wake On’ settings are turned off. My machines would wake up when I did not want them to because either a mouse would wiggle a fraction, or some packet on the LAN got intercepted.

You may have another problem, but until you are sure I’d disable all ‘Wake On’ options you can find.

Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
