Facts on IBM T40
The ThinkPad is a laptop computer that was once manufactured by IBM. IBM sold that PC group to Lenovo. IBM is however still involved in the marketing and support of the laptop.
Problems
The IBM T40 motherboard has a GPU problem and a FlewView display problem. To overcome the flex problem, which also caused the problem with the GPU video chip, the manufacturer had to reduce the motherboard flex and the physical location of the GPU to the edge of motherboard.
Considerations
Those that own a IBM ThinkPad T40 laptop and encounter the GPU problem should consider the GPU solder re-balling technique or reflow their laptop's motherboard, which simply means to re-solder the SMD chip to ensure there are no loose connections from the motherboard. If problems continue, the computer user may want to consider a motherboard replacement or contact Lenovo or IBM customer support for assistance.
