| − | + | This page provides information regarding unusual known problems, or rather, hardware/software design defects that may appear on a ThinkPad. Known problems that are related to age, are not considered unusual and will not be listed here. Some examples include: | |
| + | *[[Problem with Pixel Error|Problem with dead pixels or subpixels on TFT display panels]] | ||
| + | *[[Problem with broken inverter]] | ||
| + | *[[Problem with key and trackpoint markings on the display]] | ||
| + | *[[Problem with red display shadow|Problem with slow response rate of red subpixels on TFT display panels]] | ||
| + | *[[Problem with red tinted display|Problem with failing CCFL tubes on CCFL-backlit display panels]] | ||
| + | *[[Problem with hot surfaces]] | ||
| + | |||
| + | Hardware problems are design defects related to a physical component that resides on or in a ThinkPad, which may result in premature death or reduced functionality. Fortunately, some components are modular and can be swapped for a fault-free equivalent in certain cases. Software problems on the other hand, are design defects or mistakes related to a component's firmware. Depending on the severity of the problem, some can be easily resolved with a simple modification, but some can't and may require special tools. | ||

This page provides information regarding unusual known problems, or rather, hardware/software design defects that may appear on a ThinkPad. Known problems that are related to age, are not considered unusual and will not be listed here. Some examples include:
Hardware problems are design defects related to a physical component that resides on or in a ThinkPad, which may result in premature death or reduced functionality. Fortunately, some components are modular and can be swapped for a fault-free equivalent in certain cases. Software problems on the other hand, are design defects or mistakes related to a component's firmware. Depending on the severity of the problem, some can be easily resolved with a simple modification, but some can't and may require special tools. |
