Ensure the chip is receiving the correct 3.3V supply. If the voltage regulator (usually the 3.3V/5V "Always-On" standby IC) is failing, it may be sending excessive voltage to the KBC. Peripheral Shorts:

: Handles the keyboard scan matrix (up to 18x8) and touchpad. Why it might feel "hot" or fail:

, a "hot" KBC chip is a classic symptom of a hardware failure. If the chip is burning to the touch immediately after connecting power, it usually indicates one of the following: ctlabbd.com Internal Short Circuit
