A friend said she’s having problems with her IBM ThinkPad battery. It was not holding a charge, so she replaced it with an aftermarket one. The new battery will not charge at all. She asked a techie at school and he said something about IMB ThinkPads having a ‘block’ in them to prevent surging, and that it needs an actual IBM battery.
This isn’t my bailiwick. Is there a way around this ‘block’? Is there some ‘trick’ to making a new battery work in a ThinkPad?
