I've been noticing that my computer is randomly snapping out of sleep mode after a few hours.

I'm positive that I'm not bumping into the mouse or anything to accidentally wake it as I make sure to turn my wireless mouse off once I've finished a session on the computer. and often times the computer will wake in the middle of the night. I will select sleep mode before going to bed and when I wake up it will be running like normal, I'm really not sure what is causing this problem so if anyone has any suggestions that would be great.

Click the start orb and type device manager. When it shows up in the search results, press Enter.

Locate your network adapters and double-click on the first one. Go to the Advanced tab. Scroll through the list and look for any "Wake on..." or "WOL" entries. Make sure they are disabled.

Do this for each network adapter.

Let us know if anything changes.

If it looks like I know what I'm doing, there's a pretty good chance the only reason for that is because
I once asked someone to run chkdsk /r and a BC Advisor smacked me in the back of the head.

I am guessing that what you mean you turn off a switch on the mouse and not turn off the wireless mouse receiver.

I suspect that one possibility is there is some RF interference being picked up by the mouse receiver and triggering the computer.

To test that, if you use a USB receiver try taking it out and see what happens.

You might also look into the BIOS settings and make sure there are no settings there to Wake On Lan (WOL) for example.

I Avoid these problems by shutting down the computer at the end of the day.

Even My laptops.

Good Luck

I see LucheLibre posted as I was writing my post. Try his too.

Find out what wakes up your Windows 7 from its sleep

To find out what event/device woke up your Windows from its sleep state, go to command prompt (type cmd on the Run/Search box and press ENTER), then type this:
powercfg –lastwake

To get the most detailed info (and probably easiest) on the device that wakes your Windows up during the sleep, type:
powercfg –devicequery wake_armed

If it still doesn’t work:
Check out your Power Management Options on your Control Panel (Start, Control Panel, Power Settings, Change plan settings, Change advanced power settings).
-> “Multimedia settings” option, “When sharing media.” ->”Allow the computer to sleep.
-> Check other options one by one while you’re at it.

Hope this helps!
