Hi,

With the U6101 in place the laptop is able to turn on and display though the USB ports wont work. The U6101 IC gets really hot when the laptop is on. When U6101 is removed from the motherboard, LED3 & LED1 on the motherboard are dimly lit and the laptop cannot turn on. Any advice to get it working would be appreciated.

Regards.

resistance on TC6102 ?



it should be can turn on, please check then pins of U6101 on the motherboard, maybe there are short circuit.

The resistance on TC6102 is 0 ohms on -ve pin & OL in the +ve pin.
