Explanation

A swollen (bloated) battery physically expands inside the laptop chassis and can exert upward pressure on the keyboard and trackpad, causing keys and trackpad buttons to become unresponsive or stuck. This explains why there is no visible user-caused physical damage. A damaged digitizer (A) affects touchscreen input on tablets, not a trackpad. Distended capacitors (C) are a motherboard component failure and would cause broader system instability. A failed accelerometer (D) affects screen rotation or motion sensing, not keyboard/trackpad input.
