Salvaging a dead laptop PC

Your good old laptop PC went back to meet its maker and you can’t accept the idea of dumping it into the next waste basket (not even considering recycling, would you really want to part in such a harsh way?). Let’s not forget some of the few uses that you can still have from the old mate:

What broke down: You still can…
The screen is all dead and went black …attach a desktop display and convert it to a small desktop PC.
The screen is all dead and went black …install Linux, an SSH_server or PC_Anywhere and recycle it into a autonomous file server with low power consumption.
The motherboard is resting …scrap the 2.5″ disk drive and put it into a nice little USB box to have a new external backup solution.
The battery is out of juice …plug the power cord and convert it to a small desktop PC.
The keyboard is broken …install Linux and recycle it into a autonomous file server with low power consumption.
