Does it turn on with charger alone?
Post PPBUS_G3H voltage in this case.
If still no good, check diode mode to ground.

Does it turn on..

still cant on with charger alone.
no chime, no fan spin.
got green light on charger then few seconds becomes orange.

PPBUS_G3H diode:0.155 1.1v stable

Be sure F7140 is good.
Post U7100 basic voltages; pins 1, 2, 3, 9, 12, 13, 14, 15, 17, 19, 20, 27.
