If the chip continues to get hot instantly with all peripherals removed, use a thermal imaging camera or drop a few drops of directly onto the top of the KBC1126-NU. Turn on the power for 2–3 seconds. If the alcohol evaporates instantly on the chip, the internal short is confirmed. Repairing the Motherboard
Laptops exposed to liquid spills, faulty universal chargers, or static electricity often suffer damage to the protection diodes. This allows high voltage to hit the KBC1126-NU directly, permanently damaging its thermal threshold. Step-by-Step Motherboard Troubleshooting Protocol kbc1126nu datasheet hot

The KBC1126-NU is a highly integrated Keyboard Controller (KBC) and Embedded Controller (EC) developed by SMSC (Standard Microsystems Corporation). Since being acquired, it is now part of Microchip Technology's portfolio. The "NU" suffix specifies its package type: an LQFP-128 (Low-profile Quad Flat Package), a 128-pin surface-mount package commonly found on laptop motherboards.
