Ensure is sitting at 3.3V. If you have an oscilloscope, verify that the crystal oscillator is outputting a clean clock signal. Step 4: Reprogram the BIOS/EC ROM

Hardware reset pin for the EC. Must be high (3.3V) for the controller to operate.

Must measure 3.3V . This is the main standby power coming from the 3V/5V system regulator.
