Computer turns itself back on after being set to sleep

[Samiam]

For some reason, sometimes when I set my computer to sleep, it will turn itself back on after 10 or 15 minutes. Usually when I log back in and set it to sleep again it won't do this, but last night twice in one night.

I have absolutely no idea what's causing this, and I'm often still awake when it happens, all I see is my computer suddenly turn itself on (so no one is sneaking up and turning it on or anything). Is this is a problem with my hardware or something, should I be worried?

I used to (and still) have this problem. What usually happened was that my router was waking my computer up for some reason. Do this command in cmdprompt and see what you get:

powercfg -lastwake

You should also check your power options and make sure that wake timers are disabled as well.

when I try that I get a 0.

And speaking of my router, I connect to my router with an ethernet cable, would unplugging that solve anything?

Ah, yes, same problem I had.

Usually it happens when I'm having internet problems, and after it comes on once it doesn't do it again. I don't think it's a hardware issue but you shouldn't worry too much about it.

I've never tried the unplugging thing but it might work
