This page provides information regarding known problems with certain ThinkPad models.

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]]
  
A complete fix or a work-around for a problem, may not be possible in some circumstances.

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.
