Windows 7: PC does not wakeup

PC does not wakeup

I generally leave my PC on during the day but lately after an hour or so it will not wake up.
I have tried varying the sleep time but it makes no difference.
I end up re-booting.

Can be a number of things.

Try switching between S1 and S3 in your bios.

PSU getting old - not supplying enough current to wake up pc.

On older motherboards you have to move a jumper or two to get the mouse/keyboard (plus bios settings) to enable pc wake-up. (It's in the manual).

Usual one is a problem with graphic card badly written drivers (interfere).

Have you had a good look thru your Win7 'power' settings in control panel?

Are you attempting 'sleep' suspend to ram, 'hibernate'?

Are mouse/keyboard/hid drivers enabled (in computer management) to wake pc??

Thanks for the reply:

The PC is a 1 year old Packard Bell
I have looked at the Power settings and they are the same as before.
Sleep mode.
According to Device Manager the items you refer to are working properly.

so when did you install Win7?
Have you updated any hardware recently memory/vid card/new wireless card etc?

Go to
>right click "Command prompt" run as admin
> on black screen copy this and paste or type in
> powercfg -devicequery wake_armed

tell us the results

(careful which mouse button you press when 'armed' - you might set off a ballistic somewhere )
