A shorted USB port, keyboard, or touchpad can pull excessive current through the KBC pins.
Measure resistance to ground on the 3.3V VCC pins.
A failure within the silicon often causes immediate overheating upon applying power.
If the 3.3V standby rail is pushing higher voltage, the KBC will overheat.
It is a high-density QFP package; use plenty of flux.
Do you have a handy to check the resistance on the VCC pins ? AI responses may include mistakes. Learn more
Disconnect the keyboard and touchpad to see if the temperature drops.
Some versions require external SPI Flash programming, while others are "blank" and pull code from the main BIOS.
Corrosion between high-voltage pins and signal pins is a frequent culprit. 🔍 Troubleshooting Steps
Handles ACPI power states (S0-S5) and battery charging logic. 🌡️ Why is your KBC1126NU running hot?
