I have a 2-years old 1st Generation Lenovo Thinkpad 13, running Ubuntu.
Its battery does not charge anymore; when I plug the AC, I can use the laptop perfectly, and it shows "charging", but the percentage does not move (6% at the moment). Replacing the battery and the power supply did not solve the problem.
How may I solve this?
Rk: the model number is 20GJ-CT01WW
