computer wakes up at any time through the night

  Migwell 07:42 06 Nov 2010

If I tel my computer to go to sleep when I am finished with it for the day, sometimes about 01:00 in the morning. When I get up, or even wake through the nightI can see that it hase come back on even while in another room as the screen will be lighting up the room. The screen / monitor would just be left to go on stand-by which I prefer rather than actually switching it Off

What has caused this and how can I stop it?

My laptop which uses Win7 also, is OK an will not do this.

HP Computer, Intel i5, using Win7.

Probably a program updating itself , or Windows checking for updates , something like that would be enough to wake a sleeping PC .

Why leave it on over night. Are you so desperate for time that you cannot wait for it to start up? I have the absolute minimum of programs set to start running on boot up, and it is up and running in a little over one minute.

If I put my PC on standby during the day, sometimes it stays that way sometimes I come back to it and find it back on.
If you must leave the PC on you could just switch off the monitor, but personally I just shut everything all down at the end of the day. Apart from anything else it saves on electricity. Even on sleep or standby,or even if you shut it down, if you don't switch off at the mains the PSU is probably still alive and drawing power and costing you money!

Wake up options are normally in the BIOS I think.

You could have a look there.

"Disable wake on LAN" and "Wake on Ring" in the BIOS

Tanks Fruit Bat/\0/\ that sounds like a propper and sensable sugestion.

It is suprising how much power a computer uses in the fullness of time when left on. Why not switch it off?
