Re: ASUS X550CL - Works only with battery ?
See attached.
Interested in the voltage reading at the yellow arrow & with black meter probe to ground.
Then check again at the PU8802 IC to be sure the voltage is the same.
When the external power adapter is connected, a safe voltage should be present at the yellow arrows to inform the charger IC that the adapter is connected.
Only then will the MOSFETS turn on through the gate voltages of each.
