Having problems with your IBM ThinkPad T40 2373 Notebook ?

T40 keeps losing video randomly

\015 The computer starts up (sometimes) and it can get as far as the desktop, then, randomly, the screen shuts off. the computer is still on though, cause its still lit up and makes noise. ive tried an external monitor, and even that will shut off randomly. when you try to turn it off then back on again after the video has dissapeared, the monitor doesnt turn back on at all and it beeps 3 times. if you give it a few minutes however, it turns back on (sometimes). whats the problem?\015\012could it be the video processor failed due to overheating, maybe a bus connector failure? if so how do i fix it?\015

Answers :

It's broken solder point or points on the GPU chip. It's very common with the thinkpad T40. This can only be repair permanently by replacing the motherboard or reflowing the solder on the GPU with a heat gun. There is a utube video demonstrating the reflow process.

\015\012You can confirm this is your issue by applying strong downward pressure on your laptop just above the left corner of your touchpad and turning the laptop on. If the laptop boots completely while holding this pressure, you can be sure your laptop has this issue.

I have the same problem. I am not convinced that it is a microsoft issue. Try leaving it On for a while without booting windows. eg use a linux boot disc ( it will take ages before it gets to the point where it would actually install anything and then it asks you). When I tried this mine shut off. You could also try switching off all the power save auto switch off stuff, eg when you press the power button, close the lid etc, as maybe it is a bad connection.

Machine freeze up randomly. Must do a hard shutdown. Seems like a motherboard failure Does anyone know how I can get support for my M465-E laptop? MPC is not responding to any of my emails and their phone is always busy. Gateway customer support only responds with a canned answer which is "Contact MPC for support". My laptop is considered a business division support issue and nobody is helping. It is still under warranty and I need a new MB, since mine keeps rebooting itself over and over.
