Windows 7 Sleep problems.

[Joe 90]

Not too sure whats up but basically last night I put my PC to sleep and after about half an hour the fans started up and the machine had woken itself up. I set it to sleep again and it stayed like that for the night.

Then this morning whilst I was watching the various saturday morning cooking programs it started up again. With a blinking power light and constant HDD light. The display wasn't being output and it wasn't responding to keyboard/mouse input.
I forced a shutdown by holding the power button in, powered back up and it started as though it'd just come out of sleep. Everything is still stored in memory but it did actually shutdown :/

Any ideas wtfs goin wrong?

This morning, it was probably hibernating. You can turn that off if you don't want it to do that.

Last night, dunno. Check scheduled tasks for something that might want to wake your computer up.

Have a look in the logs, see if there's any events there for the time it woke up.

well hibernation is dissabled, i don't have any scheduled jobs and the logs look mostly okay.
there is a problem with an error from some ATi stuff though; atikmdag :/

oh, and last night it would appear that another PC on the LAN tried to tell my PC it was master browser and they held an election.
I don't understand that, but it does amuse me.

Well that accounts for the wakeup last night then. I thought it was only domains that did that stuff, but obviously workgroups do it too.

recently i've shutdown the system and its kept the fans spinning. power and HDD LEDs go off, but my bright blue case fans stay on :/
any ideas?

Does your PSU have a fan channel? Did you connect the fans to it? If it does, and you did, they'll stay on for a few minutes.

My laptop has a sleep problem too (Vista). It refuses to stay asleep. Set it to go to sleep and it doesn't, tell it to go to sleep and it wakes back up a few minutes later. No idea what's going on there. :(

[Joe 90]

All the fans just plug into the PSUs molex connectors I think.

I bought new fans recently and they were all big 4 pin molex ones :/

[Mark]

Switch off and leave for five minutes. If that doesn't help then there's a problem - most likely PSU.

Still, that'll teach you for buying bright blue fans. :p

lol. they were fairly cheap and highly rated :/

Sounds weird - maybe enable hibernation and see how that goes? I have to say since putting it on my netbook the power management has been flawless, shut the lid and it goes into standby then after 5 minutes or so hibernates - boots instantly from standby and in about 10 seconds from hibernation which is brilliant really :)

i'll have to give it a go when i get back to uni tomorrow night.

hopefully its as good on a PC :)
