    Can anyone please help?
    My Toshiba Satellite L855-149 will not boot up Windows or even boot a disc to install a new copy of windows 7. It keeps doing a hard shut down when trying to load windows 7 screen. It will only boot up in safe mode.

    Its kinda strange .it has my head wrecked.
    Has anyone had this same problem?
    Please help

    As I can see you have tested it on battery power supply. Does the same happen on AC power supply?

    Anyway, this issue is for service so I strongly recommend you to contact nearest Toshiba service provider and ask for help. In my opinion with such issues there is no much you can do about that.

    Sounds like the GPU would overheat.
    Usually the unexpected shut down protects the hardware from damage.
    Did you change something in the past? Some drivers, etc…?
    Its strongly recommended to use the graphic drivers from Toshiba page since such drivers are modified and designed for mobile usage.
