test voltage on TPS51125 voltage in all pins , test voltage on Q6206 drain pin 5 6 7 8 for +19V VBAT ,test Q6207 Q6206 for any short D S G

Just a suggestion. Check that usb ports are no broken/shorted.

Hi!

USB ok, Q6206,07 ok, vbat ok, TPS replaced. Entrip2 0V, Entrip1 1.3V i think that's the problem.
