No, I'm not having problems sleeping.... my computer is. When I try to put my computer into Hibernation mode, I get the following message: "The device driver for the 'Microsoft PS/2 Keyboard (IntelliType Pro)' device is preventing the machine from entering hibernation. Please close all programs and try again. If the problem persists, you may need to update this driver." It's been doing this ever since I built the system last year, but I have never been able to determine an exact cause or solution. From the best I can tell, all the drivers are up to date. Has anybody else had this problem - if so, have you resolved it, and if yes, how? Thanks a lot! P.S. System Info is in my profile.
