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.

The easy way is to take the charger to a shop and have it checked. This requires a voltmeter. If it is bad then replace it. If it is good then the connector where the charger plugs in is probably bad. Unless you are mechanically inclined take it to a shop. I charge $30 to $50 for this type of repair.

Does not power up.


Remove the battery and try to turn on the laptop without the cord plugged in to allow the device to completely discharge. Put the battery back in and hold the power button in for 45 seconds, the lights should flash and then turn the laptop on normally.

This always works for my laptop.
