A user called the help desk to report an issue with a laptop.

The most likely cause of the issue is that the laptop has a swollen battery, which is a condition where the battery expands due to gas buildup inside the cells. A swollen battery can cause physical damage to the laptop, such as pushing against the track pad or keyboard and preventing them from functioning properly. The technician should inspect the battery and replace it if it is swollen. A damaged digitizer is not the cause of the issue, as the digitizer is a component that converts touch input into digital signals, and it does not affect the track pad or keyboard. Distended capacitors are not the cause either, as capacitors are electronic components that store electric charge, and they do not affect the track pad or keyboard. A failed accelerometer is not the cause as well, as an accelerometer is a sensor that measures acceleration, and it does not affect the track pad or keyboard.
