I installed a new hard disk, so do you think I should install Toshiba utilities in Seven?
From: William Sommerwerck on 24 Apr 2010 17:46 You said that this problem didn't occur with certain software -- only BIOS and W7. Which suggests a software problem. Toshiba notebooks have not generally have this problem. You could push and pull the AC adapter's plug all day long, and the computer didn't mind. I suspect the software interprets the tiny "glitch" when the plug is inserted (or removed) as a power loss, or a command to switch to Sleep/Standby.

Does the hard drive light come on solid when it freezes, indicating it is in some sort of loop, or does it go out, or does it flash intermittently indicating it is not locked up?

Compaq, they were nortorious for having a special partition they would fail to boot if they didn't find.
