Thinkpad 2373: boot and freeze problems.


raodonald

If you are having trouble with your fan running it is possible that the notebook is over heating.

Think about when it ran good and when it did not. Was the fan running and/or was it cooler at that time. Also if you are in a place where it is cool outside you might take the system outside in the cool to see if this makes a difference.

If is does work more when it is colder then most likely the fan is not cooling the system properly.

Let me know if you have any more problems or questions

T40 hangs after boot up. Sometimes does not show anything on boot


it may be because of the cpu cooler is so full of dust that the fan cant go around and the cpu gets hot and the whole system freezes or something else is totaly screwed up

IBM T40 Laptop screen goes black, will not come back


First of all, you have to check whether you can see video signal with surrounding light tilting the screen.
If you can see dim image, all you have to do is replace back-light inverter or fix it. Usually, the fuse is open and you can connect it by simple soldering.
If you can't see dim image, it is another problems.
Give it a try.

IBM Thinkpad T40 Problem Booting Up


I have a T41 doing this, and pressing on the big ATI video chip (under the wireless card, under the touchpad) would change the machine's mood from bad to good (or vice versa). There are sites saying motherboard flex is the problem, and the solder balls of the video chip (GPU) are the weak link. There is a service on ebay the repairs the solder balls of ATI GPUs for $50, which I will be trying out. Or check Youtube for how to reflow the solder yourself with a 1500 watt heater and an infrared thermometer.

T40 2373 ibm fan error


One of three things; 1- when the fan codes on some IBM's, the code locks in the bios, there is a download the has to be ran in order to clear the code and the machine to run properly. Check IBM's support site to see if this is the case for your machine 2- If the machine overheated in the process of the fan going out, then the processor may have been damaged, causing the problem and 3- if there was a malfunction with the motherboard which initially caused the fan to stop working, a new fan won't work either. Test the old fan by hooking power up to it, it is power direct and has two leads positive and negative, when power is applied it will run or not. If it does run then the problem is with the motherboard. Try these and get back to me.
