I own an IBM Thinkpad T22 and some time ago its AC-DC adapter has begun to malfunction which inherently lead to a mainboard failure (I hope). Now it is impossible to turn it on, either on AC power or on battery.
As I am an engineer in electronics, I would like to repair it myself. Can anyone give me some pieces of information about the laptop mainboard, especially its power supply?
Thank you in advance.
