T20 wont turn on


make sure the battery is unplugged from the laptop and only hook up the ac adapter. If you can't get it to turn on then try anotherr knowng good working adapter and if it still can't turn on then the motherboard is bad and will need to be replaced.

Ibm thinkpad turn on no work


If you're not getting any external display action then that means it's probably a motherboard issue / hardware issue.

First thing you're gonna want to try is reseating the memory and trying to boot the computer with the battery out.

Second, if that doesn't work next thing you can try is removing the cmos battery (with the battery and power adapter out) and letting it sit for 5 minutes with the cmos battery out.

Also, do you get any led lights or any kind of action from the laptop (fans, beeps, etc.)?
