PC coming out of sleep at 3 every morning

[adz08]

Hi

Been trying to work this out for a while, I want to put my computer into sleep mode at night rather than turning it off. But for some reason, every morning at 3 it starts up. I've had a look through and changed the time Windows checks for updates which was set at 3 but thats not helped.

Any ideas? What else runs at 3 that would force the PC to come out of sleep mode?

My PC's in my bedroom so don't want it waking me up every morning!

Thanks for any help!

Anti Virus scan?

Updates or defrag?

As above - Is the default time for Windows Update not around 03:00?

Check for entries in the task scheduler.

Thanks for the help everyone.

I dont think theres a defrag running at all, as I said windows update is now set to 4 pm for updates (it was 3AM). And I used Microsoft Security Essentials which I think updates through the Windows Update.

Wheres the task scheduler? That may hold the answer to my problem!

Windows update is scheduled to run by default at 3am

[ehhhhhhh]

click start ----> "search programs and files" -----> type in task scheduler and it will come up

Check it's not Windows Media Centre trying to go online for program updates. I had a similar, bewildering wake from sleep issue on one of my Windows 7 PCs and it turned out to be that.
Have a look here, for example.

Thanks I'll give that a look later. I didn't realise MC had automatic update either!

Sometimes there's an option in the BIOS for the PC to wake up at a particular time, I think. Maybe that's it?

change the winodows clock by 12 hours?

just to get some sleep and make sure it's a timed function and not something else, like Wake on Lan on your BIOS

change the winodows clock by 12 hours?

Might want to turn off automatic time synchronisation too then

Thanks!

I had a quick look at the Task Scheduler last night and there are a few things set for 2.30 and 3.00. Like adobe updater and things.

Why would companies set their update times for early morning? Surely thats when the majority of PC's are switched off?

I think it's because they assume your PC is going to be on 24/7 so they pick a time you not likely to be using it to do the updates. Have you managed to disable the tasks?
