        The questions i would ask is:

        Does it appear to boot up, flashing hard drive led, or accessing a bootable usb drive?
        Has it had the bios flashed, then stopped working?
        Does it charge the battery.

        Basically does it show any activity to indicate its not fully dead.

        Has it been overheated.

        Is the memory ok and in the correct slot, some laptops are picky.

        Have a deep think about what it does do :-)
