I'm having trouble with the battery on the IBM thinkpad t22. For some reason it's not charging,eventhough the battery light is green and shows that it is fully charged. As a result as soon as the A/C adapter is disconnected it turns off. So it has to stay connected the whole time if not it shuts off.
I bought a second battery, charged it overnight, but I'm still having the same problem. The battery light is green, which means a fully charged battery, but it's not holding the charge. When i check the power source for the battery it reads that it is only 29%total battery power remaining. That's with the new battery and it connected to the A?C adapter.
Basically the batteries aren't charging. Could it be that both batteries are dead, even the new one? Or something else?
I have seen a similar issue with a Dell Inspirion 600m, the problem with that computer was the AC adaptor for what ever reason would only power the laptop but not charge the battery. I resolved the issue by replacing the AC adaptor, with a new adaptor from Dell and not a cheap after market one the problem went away and the batteries were charging.
Both batteries could be dead. But if you bought a new battery, it's unlikely. I don't know what green light you see, but if it's on the power adapter, it just means it's turned on--not that it is charging.
Two possibilities: Your power adapter is bad or the motherboard is bad. Because you say the computer works if plugged in, then you have ruled out the adapter.
You should be checking/cleaning the battery contacts and if all else fails, going for a new motherboard.
