My Dell desktop had been going in and out of sleep mode for the last 4 years without a problem.

But recently, it no longer is able to wake up from sleep. The keyboard, mouse or start button no longer can get a response out of it. I have changes the batteries in my wireless mouse and keyboard.

I have tried to adjust every possible configuration in the power settings but nothing has solved it.

I am now using Hibernate mode. It wakes from hibernation about 70% of the time.
I would very much like to be able to use sleep mode again.
Any suggestions?

Thanks

I have been re-imaging a Dell laptop recently and have had similar issues with both 32-Bit and 64-Bit versions of Windows 7 - I am guessing since you posted here that you are running Windows 7 ,since you don't specify your OS or laptop model.

After the initial install of Windows 7 (both versions), Sleep and Hibernate worked correctly, then became intermittent and eventually I was almost never able to get them to work.

 

From the research I did into this problem, this is likely a driver issue - the usual suspects being video or wireless drivers.

 

In my case, the problem was neither of these but was driver related.

 

Note that Windows Update has pushed out a few driver updates recently - video and Gbit Lan drivers were two I spotted in case you don't think you have updated your drivers.

 

I resolved this issue by restoring back using system restore, then systematically reapplying driver updates and testing Sleep and Hibernate and either rolling back drivers or creating new retsore points.

 

I think that the problem is that newer drivers from the chipset manufacturers aren't always 100% compatible with all PC's, and sometimes you have to stick with the older drivers provided (and possibly modified) by the PC manufacturers.
