Device was water damaged. Corossion at the trackpad and lcd connector and at U7270.
PPBUS at 12.6V
Thermal scanning showing U7270 heating up.
Replaced it. Still a very very very low heat signature on U7270.

Still the same. no mouse click. intial fan spin for about 2-3 seconds then after sometime normal fan spin - without battery connected.
with battery no fan spin and lower amp draw.

Will not detect in DFU.

Forced into DFU. IT was succesful and gave a padlock sign. But still the same symtoms
