Question about IBM ThinkPad T20 2647 Notebook

1 Answer

Power supply When starting the thinkpad with the on button the disk led flashes for a very short moment and the battry led extinguishes while lighting up shortly thereafter. The machine does not make a single sound. Is this a known problem? I tried another power brick, same result, I took out the Hard drive, same problem. I removed the internal modem, same result. I detached the battery, same result.

This is a common problem, that involves the power management system on the motherboard. There are few places that can fix the problem, and they will cost you more than replacing the motherboard. I'm going to suggest replacing the motherboard, it's much cheaper and easier than trying to repair the old board. You can find one at a decent price on Ebay. Here's a link for the hardware maintenance manual for the T20 if you would like to replace the board yourself.

Pc not starting When I press power button on cpu


If you are not getting the computer to start up but you are getting the fans to whir for a moment and the keyboard lights to flash, then that means that you probably have a bad motherboard. If you had a bad power supply, most likely none of these secondary indicators would be present. I would advise taking the computer to a local computer repair shop and having a professional investigate the problem. More than likely, he will be able to tell you the cause of your problem in short order.
