PC won't "sleep" first time

Put my PC to sleep and it dutifully goes into sleep mode after a minute or so then promptly restarts.

Have to do it 3 or 4 times before it finally sleeps.

I suspect a programme may be slow in closing, but any idea which one please?

IE, Office, etc. are all closed.

Many thanks

without indepth knowledge of your system, or even basic as we dont have a clue what windows/cpu/motherboard configuration you have, I would hazard a guess that it could be a USB device, mouse / kb etc that is enabled to wake the computer up.

Go to device manage and check the power options for each usb device and see if any are enabled for waking up the PC

You need to sing it a lullaby

did you look at that?

I think I had something similar on my PC when it ran Fister around 6 years ago.

I had to change the power settings to disable what was causing it (which I forget now but could have been a USB one as Mark suggested).

Nothing I can see that is set to wake up.

 

[moonloops]

Type cmd in search box or in start run menu.

In command prompt box type:
powercfg -lastwake

That should give an idea on what woke it up.

here you go!

What is plugged in to your USB ports on the back of the PC?

 

[moonloops]

here you go!

Yep it is a USB device. You need to fire up device manager, go through the USB devices and turn of the ability for it to wake the PC

 

[Palfrem]

AHA! Bingo.

It's the USB mouse - I have disabled the "wake up"

Thanks all - your help is much appreciated.

Makes sense as you can get "mouse creep"
