I haven't found exactly the same situation here, so will start a new thread.
A few nights ago, I was using my T60 to view some PDF files. I shut it down, unplugged the AC, closed the lid, and set it aside. The next morning, it was simply dead. Won't start on the battery, which must have been fully charged when I shut down, won't start on AC adapter. It doesn't even light any LEDs when the adapter is plugged-in. I've tested the power output of the adapter, and it is 20.5 volts, which looks normal. Took it to a shop, where they used a new AC adapter - nothing, again, not even an LED.
The shop kept it overnight, did whatever tests they do without opening the laptop, and nothing. Wouldn't work when docked, they said.
So, what's going on? No battery power, no AC power, no LED indicators, nuthin. It was bought used a few months ago, and the 1-year warranty is over (that figures!) ... Shop wants to stick in a new motherboard, but as they don't even know WHY or WHAT has happened, I don't want that expense. Help, if anyone can !
I think (hope) is something minor... something have to happend when you turn the laptop on... a led, the fan, the hdd...
Check the case sensor. It may still be blocked when you open the cover .I’m talking about the sensor that turns the computer off or standby when you close the cover.
Let's try this: remove the battery, hard and media drives and unplug the AC adapter. Press the "power" button ten times in the row, holding it down for 10 seconds each time and 30 seconds the last time.
Plug the AC adapter back in and try to power the machine on.
Please DO NOT PM me with requests for individual support, but post your questions and concerns in the appropriate section of the forum where other users can benefit from them as well. Thank you.
I was going to say the same thing but if this don't work take out the CMOS battery and hold the power button for 10 seconds 10 times this will totaly discharge the systemboard. If this don't work you might have a bad systemboard.
I had already tried the push-power-button routine, and it didn't help. What bugs me is that whatever happened seems to have happened when the machine wasn't even running, although I didn't see the final seconds of 'life' (I was falling asleep, and closed the lid while it was still shutting down)
The repair shop gave me the usual "replace the motherboard" line, but without knowing what happened, I'd rather just buy a used T42 or T43 and save the dead T60 carcass for parts or a doorstop. Only reason I stick with Thinkpads is the stupid TrackPoint, which I insist upon. My loss, I'm afraid.
I wouldn't replace the MB till I was sure there was power being fed into it.
If your battery is dead (could be if you actually fell asleep and left it on) and your A/C adapter female plug is not connected or broken, no power, no lights, no boot.
Check your power line from the A/C adapter to the mother board.
Do I remember someone saying there was an inline fuse there?
Here's an update on my problem: I unplugged the memory and the CMOS battery (why is that plug so delicate?) and let it sit for an hour, then replaced both. Nothing. So, I gave up and set the laptop aside. About a week later, I pushed the Power button for the heck of it - and the puter started! It seems to run fine, but with this problem: the Power button works ONLY if on battery,and does nothing if the laptop is plugged-in ; however, if it is Off and then the AC adapter is connected, it automatically starts!
Strange.
So, it works now, but I don't trust it for anything important.
