I have installed a 2nd hard drive into my laptop and now Windows 7 refuses to shutdown all or sleep all the way.
The screen goes black and the computer's fan just stays spinning and it never enters sleep or hibernate mode.
I have checked the sleep settings and they appear to be just fine. Additionally everything works just fine as long as leave the cdrom in instead of the hard drive.
I own an elitebook 8460p and I am replacing the cdrom with a 3.5 in sata hard drive.
