The problem with 600 series batteries

ThinkPad 600 power management causes batteries to die before they should. Read more about this on the associated problem page.

Reviving Batteries

Some people experience sudden drops in their batteries capacity.

A way to get these batteries back to full capacity is to run the "Battery Rundown" function of IBMs "PC Doctor for DOS". The program is downloadable from IBMs support site as three floppy disk images. For those who do not have a floppy, David Smith prepared a bootable CD image from the T22 floppy images.
