IBM thinkpad T21

\015 My IBM T21 thinkpad will not stay powered on.\302\240This started happening a couple of months ago and I noticed that if I took the battery out for a couple of days and put it back in, the machince would work again.\302\240\302\240However after a while (a couple of weeks) the problem re-occured.\302\240 I then noticed that if I kept the battery out completely and just ran off the power cord the machine worked fine.\302\240 This again worked for about a month.\302\240 Now, I can't get the laptop to stay on for more than a minute and it just shuts down and doesn't come back on.\302\240 If I unplug the power cord and wait a day, it'll fire back up but again only for a minute.\302\240 One it goes down, Ihave to keep it unplugged for about a day to be able to power it back on and get to CMOS settings or XP login screen.\302\240 This has nothing to do with the OS as I've seen it die while sitting on the CMOS screen settings.\302\240\302\240 Any idea what parts might need to be replaced?\302\240\302\240\302\240 I thought about replacing the battery\302\240but since it doesn't work even without the battery in it (when it's powered thru AC)) would that make a differnce?\302\240\302\240 Could the CMOS battery be the issue?\302\240\302\240\302\240 I'd like to be able to continue using this or at least keep it on long enough to move some more data off it.\302\240\302\240\302\240 Thanks\015

Answers :

I had a similar problem after My pc got damp in a bag in the rain. I contacted IBM and was given this fix which I am supprised worked but it did so here it is cannot hurt to try. Remove the main battery and the mains power supply press the power on button for 17 seconds. This I think is to drain all the power from the laptop altogether. Replace the mains lead and turn on. Once the laptop has openen up into windows turn it off and replace the mains battery then power on again. In my case this worked I hope this helps.
Check connection near Video invertor board and motherboard. With heat, this connector tends to come of the board. It is a 4 pin connector which joins the Mobo and video board. Also check your processor heat sinking compound, make sure there is enuf. Processor will tend to overheat and shut the sytem down. The latter fix requires you take the system apart to check.
