machine will not ENTER sleep.
eMachines e4525 - clean installed some time ago with Windows 7 Pro.
machine appears to bhave perfectly, except when emerging from sleep or hibernation (hibernation currently disabled until I can get sleep working).
Had AVG and MSE installed prior to installing Norton 360 a couple of months ago. AVG was properly removed before MSE was installed, but Norton was overlaid on top of MSE, and some time later (when I was called in) MSE was removed at the owner's request (they'd paid for Norton, they were going to use it...).
Recently the machine exhibited the following behaviour....
All is well until it goes to sleep.
at some point in the sleep process, somthing appears to happen - if the machine is woken up fairly quickly, it's OK, but if it is allowed to sit for more than a minute or two in sleep, when awoken, it simply switches off.
A normal reboot fails just after the Win7 flag comes together and the machine switches off - Startup repair exhibits the same behaviour.
Safe Mode boot is OK (usually) - and fixes the boot problem even if the machine is restarted from the login screen.
The only significant error messages in Event Viewer appear to be referencing NTFS problems in a VolumeShadowCopy??
When I first got the machine, there was a fair amount of corruption in a CHKDSK /R - that was fixed, and there were no bad sectors.
SFC was clear.
There are a couple of HAL eventID 12 errors in the log.
Just ran CHKDSK /F (again) and there's only a couple of bad Index entries found, after around 10 failed wake-ups.
No other clues in Event Viewer.
I've also tried changing the Sleep option in BIOS from S1/S3 to S3 with no effect.
Next step is to uninstall (ane remove) Norton, I suspect - unless someone can come up with a better idea??
