Question about IBM ThinkPad T22 2647 Notebook
My T22 will not charge the battery or even recognize that it has a battery (power mizer says battery is unknown). Have replaced the battery and the motherboard & tried 2 power supplies. The battery indicator led flashes yellow indicating a discharged battery. Any ideas?
Put the new battery in and restart windows...this worked for me

Take it to a very good technician who will open it up and check a dry joint in the charging system. Sometimes if you donot attend to it quickly you may find your T22 refusing to power at all with the AC Adaptor. Delicate soldering may solve your problem. Power may not be getting to the charging circuit and the battery thus it is totaly discharged.
