IBM T21 shuting down

My T21 laptop boots ok but after running for a while shuts down. I am not sure what is causing this, I removed battery and ran without with same results. I was able to run a diagnostic on the computer and all systems passed. Fan is running as air is comming out of the fan holes on the side of unit. Any suggestions. Thanks

IBM -t21 does not boot (all the time)

I am wondering about the environment in which you normally use this unit, which is heat sensitive, and
which, after it cools off a bit will work as you say after it is allowed to dissipate heat after use.

Make sure the space in which it used is not overheated and preferably air-conditioned. Try to maintain
room temperature of 68 degrees Fahrenheit or lower down to a minimum of 40 degrees.

Thinkpad T21 Boot Problems Problems

This is caused by a system board failure. Take the laptop apart again and check all of your connections. Also make sure the ram and processor are seated correctly. You can also try hooking up an external monitor to see if any errors display. This may be an indication that the video cable connected to the system board is not fully connected.

IBM thinkpad T21 overheating?

Does the battery get very hot? If so try running the laptop with it removed! This problem might also caused by a faulty heat sensor on the motherboard. Given the current cost of new laptops I wouldn't spend a lot of money on any repair options, but you could invest in a "laptop cooler" or chill mat see this link

Nothing appear on the screen

Remove any devices connected and power it on by itslef, either on battery or power source, if it doesnt work, it may have bad processor, When they go bad most laptops wont boot period.

Travelmate 2310 keyboard and touchpad problem

Boot up the system (without the battery).
When the system runs normaly then place the battery on its normal bay.
Shut down bij removing the power from the system.
* Make sure you have not installed any Windows power saving tools, meaning let it run on the battery till it dies *
Wait till the systems shuts down by itself.
Boot your system again (with the battery in its bay and everything will work out fine.
Shuting down by removing the power support (AC) booting up AND your keyboard with touchpad will work again.
So intill you have a new battery, you need to shut-down by removing the AC power and leave the battery in its bay.
You can not shut-down on the normal way any more untill you have replaced the battery.
