Hi,

I have been trying to resolve a problem with my computer going in to sleep mode but unfortunately, all the steps that I have followed (from page 1 of this thread) have not resolved my problem. The issue is that I can get my laptop to go into sleep mode by pressing either the power button once, closing the lid or selecting 'sleep' from the menus but it will not go in to sleep mode automatically. It will activate the screen saver and then turn of the screen OK but just refuses to go to sleep mode. Any further help as to how I may resolve this would be most appreciated.

Many Thanks

Andy.

In addition, disconnect any external device (ex: USB, printer, etc...) from the computer to see if it may be a cause as well.

Hope this helps,

Hi Shawn,

Many Thanks for your reply. I don't have any external devices connected to my computer right now so don't think it is that causing the problem. I did just check my scheduled tasks again and noticed that there are 4 tasks which appear to be running permanently. Could this be what is causing the problem? I've attached a screenshot of what they are so not sure what they are and if they should be running permanently.

Regards,

Andy.

No Luck I'm afraid. I stopped the running tasks/closed all programs but still sleep would not work. Interestingly, when I re-boot my computer and do not touch anything, just leave it in the User Selection screen, it will go into sleep automatically as expected. However, as soon as it is brought out of sleep with the press of a key/movement on touchpad, it will no longer go back into sleep mode. Could this give a clue as to what it may be?

Thanks for the link. Unfortunately, this did not fix the problem. However, I think I may have identified the issue. I have a device entitled 'NVIDIA nForce 10/100/100 Mbps Ethernet' which when disabled, causes the sleep operation to work correctly. The issue now becomes how to fix this. The driver version is 73.3.5.0 so I guess the first thing is to check it is up to date. The 'Allow computer to turn of the device' option is checked so that is not the issue. Must be a problem with the driver.

The Allow this device to wake the computer option is unchecked. In the advanced settings, the only apparent option related to Wake is a WakeOnLAN from PowerOff option which is set to enabled. There are no errors in the general tab.
