I bought a used Thinkpad A22M for cheap, the advertisement 
was clear saying that machine didn't work.
This night I tried to repair it but without success, its a 
shame because this model is a beast, the high resolution 
screen and the onboard graphics make a perfect machine for 
games from Win9x era.
I have two Thinkpads 600x both working but without the 
screens, I can plug these on a monitor and play with it, 
the flat notebook without the screen looks nice, the chassis 
remember me a typewriter. The 600x Thinkpad is good for 
production and office tasks, but for games it sucks. 
The Neomagic onboard video chip is a nightmare, don't have 
any 3D support and the Sound Blaster emulation in DOS is 
terrible too.
