    Replace the display panel's backlight inverter board to restore correct power regulation across the upper palm rest.

Cevap

Disconnect power, carefully remove the swollen battery, and dispose of it following hazardous waste safety guidelines.
A swollen Lithium-ion battery presents an immediate fire and physical hazard. The technician must disconnect AC power, safely remove the battery, and dispose of it according to hazardous material protocols to prevent further damage to components like the touchpad.

Adım Adım Çözüm

1
Identify the root cause of the physical touchpad distortion.
The expanded battery underneath the palm rest is exerting upward mechanical pressure on the touchpad assembly.
Lithium-ion batteries accumulate gas and swell when aging, overcharging, or suffering internal damage.
2
Determine the necessary safety and remediation protocol.
Disconnect all power sources, remove the damaged battery safely, and place it in a safe container for hazardous waste recycling.
Swollen batteries pose an imminent fire hazard and must be handled and disposed of per environmental safety procedures.
