I have just figured out how to set my Media Center PC so that I can turn it off to standby (to RAM) and back on again by the remote, but the problem is it keeps turning itself back on overnight

I have disabled all the wake-up on LAN etc in the bios, and can't find any scheduled tasks that might be waking it up? It doesn't have a mouse or keyboard plugged in (except the Media Center Infa red remote and keyboard) so it can't be that...

I have also left it on in the day for 4 hours or so and it hasn't come back on.

I'm stumped!

 

it could be waking up to download automatic updates, Ive seen Adobe applications on SIS chipset motherboards do this when updating, disable the net connection if it has one when you put it on standby and see if this resolves the issue... if it does or does not post back and we can attempt to resolve this permantly

Thanks for the reply. I did recently install some updated SIS chipset drivers, although I have no Adobe programs installed on it. It is a fresh install with all Windows updates and only NVidia PureVideo and DivX installed, neither of which check for updates as far as I am aware.

Automatic Windows updates are turned off as well. The LAN is via a USB wireless dongle, however I shall disable that tonight and see if it makes a difference. I have just set the Windows clock to 11:55pm and put it in S3 standby, but it hasn't turned itself on at midnight which is when I thought it might be happening!

I have enabled bootlog, but it doesn't seem to log the time of standby/resumes so I can't pinpoint exactly when it is happening.

 

I'm getting somewhere now, the application log showed me things starting at 1:01am for two days in a row, so I just set it to 1am and hey presto, it booted up.

I then reset it to 1am and left it in Windows to find that the Windows Media Program Guide started to download at that time (odd as it is set to download whenever connected to the net!) I set it to manual download only and did some more testing and it looks like it has done the job!
