I had 2 identical laptops. The video died on one and I swapped hard drives. Since putting different drive in laptop it won't load bios frequently. If I remove battery and unplug power computer will boot normally. After shut down or restart bios will again not load. LCD backlight will come on. Tried removing hard drive, removing one stick of ram at a time, putting old hard drive back in. Symtom continues. I think if it were the mobo it would not start and run. Once started it runs normally for hours so I don't think it is a heat issue. Installed newest bios from Toshiba with no change. Hope someone has an idea or two. Downloaded and ran hd diagnostic from WD and hard drive checks out good. Occasionally system will not shut down but that is a software issue based on turning off start programs and system shuts down normally.

Sounds like you have a hard ware issue with the second laptop..
I am assuming that you bought both PC from an Auction...

Pull the working LCD Monitor and attached components out of one and replace the one that is not working... as the one that your currently trying to use should be used for spare parts.

Thanks, I actually bought both from Wal Mart about 6 weeks apart. One for my son who has now graduated and one for my daughter who graduates in December. The unit that had a video failure seems to have been caused by a mb failure as well. I am also having shutdown issues with the 2nd computer and now it will only boot if I remove the battery, unplug the ps, and hold the power button on for a few seconds. Sometimes it will reboot after removing and replacing the hard drive or ram. I am tempted to try a full system reload from the original disc but hate to lose all my daughters stuff. I have worked on desktops for years and this type of problem could be fixed by a bios reset but I have no idea how to do this on a laptop without removing the battery and have not taken the case apart far enough to find it.
