[Thinkpad] Thinkpad 600 Battery Pack problem

[David Gemmell - VK4GL]

Hi,

After reading many of the postings on TP600 battery pack 
problems, I would like to have a go at repairing mine.

And - please - I do understand all the warnings about this - 
(the sky will fall in  - etc etc,)
but I do have the required knowledge and equipment.

Does anyone have a SCHEMATIC of the charge control 
circuitry which is built into the battery pack?

Thanks

David
