  IBM PC Convertible 5140 Laptop by Bill Degnan - 12/07/2008 22:55

What make these IBM laptops tick, anyway?

Recently I have been learning more about what you can and can't do with an IBM 5140 laptop. It's a non-PS/2 from 1986 that was popular until the PS/2 laptops started appearing a few years later. Surprisingly, a lot of the units I have come across still have working batteries!

I need more power supplies.
