Overvoltage from a faulty power adapter or charging circuit can damage the chip's internal logic.

Sometimes the chip runs hot because a peripheral device it controls (such as a USB port controller, a LAN chip, or the touchpad assembly) is shorted, causing the KBC's internal General Purpose Input/Output (GPIO) protection diodes to sink excessive current. Disconnect all peripheral ribbon cables to isolate the IC. 🔄 Replacement and Firmware Programming Notes
