My lenovo lap top screen stays black even if the computer is on..
hi msinon, connect another external screen to the IBM-machine to check if simply the screen is broken.
If that does not help, remove the RAM-memory module (see instructions or manual), retry booting up without it, if still not lucky, the mainboard is broken and you will have to exchange it or get another new machine.
Think of transferring the old harddisk to the new laptop or keeping it as an external back-up source(you will have to buy an USB to SATA adaptor plus harddisk case) sa you can use it like a flash drive...
good luck
