I used the upgrade process in Windows 7 to go to Windows 7 from Vista. Everything works well except when I try to sleep (close the lid on laptop) or logoff. The system freezes sometimes and I have to force the system down with a power off.
It appears that the first attempt usually works. The next logoff/sleep is when the problem appears.
I have removed all third party software and the problem still occurs.
I updated to latest bios from Compaq for CQ70-134CA Laptop. No luck.
I changed the Power Plan to disable the sleep mode when the lid is closed. The system still freezes when the system goes into sleep mode after the set timeout.
I changed the Power Plan so that the hard drive does not go in power saving mode. Finally the system is stable but never goes into sleep mode.
Does anyone out there think that the hard disk going into Power Saving mode is the cause of this problem?
Any ideas out there?
