Thinkpad T61 no power

kurtismonger · 06-08-2009, 10:36 AM

I have a Lenovo T61 Thinkpad that is about 18 months old. Yesterday it was working fine and I left it on to go do some things. when I came back it was off and now it will not boot. No power light, no battery light, nothing. I've removed and reseated the battery, held the power button, and checked that I'm getting good power from the AC adapter. I pulled the hard drive and my data is fine. Seems like it may be the jack as if it was getting any power at all the battery charge light would be on, even if the mboard or something was dead?

UPDATE

It doesn't appear to be the jack. I'm getting 20V to the system board.

Test output voltage of AC adapter or test it in another (similar laptop).
Test battery in another (similar laptop).

Also Try to:

Startup on battery only
Startup on AC only

If symptoms persist or if this has been done...

Try the steps below:

Power OFF the computer
Remove the battery
Unplug AC
Press and hold Power ON button for 30 secs. at least
Put back the battery
Plug back AC
Power ON as normal

If the same thing happens...

Take it apart/Disassemble the laptop
Remove the rest, except RAM, mobo, LCD and power ON switch
Power ON using adapter
