Having problems with your IBM ThinkPad A31 Notebook ?

My thinkpad A31 2653 pc doesn't always properly initiate the the power-on self test (post). Sometimes I press the on but and the initial lights by the power swith come on as normal whether connected to battery or ac power and then nothing else happens. I power off the unit and try again. After a random number of attempts the "post" begins and the machine boots and act normally.


Answers :

The power switch works by causing a piece of plastic to press a button on the motherboard. Over time sometimes the mainboard has shifted or part of the plastic button has broken off or wore down. There a good connection is not made with the switch. Nothing to worry about.
Please go to bios setup. you can enable or disable your power on self test.
