hello
the customer brought this lap with charge ok but cannot switch it on.
i found the switch connector on board not good , so i tried with the 2 pins of switch, the laptop goes ok , i decided to change this connector, after that the laptop powers on for 2-3 sec with no screen and shuts off. i found U11 hot and found the pins 1-2-3 of the bios 1.1v

pu6: at pin 8= 3.3v before and after the same at pin 17= 5. v before and after
u22 bios: pin3=1.11 pin7=0.27v and pin 8=1.1v also the same before and after.
pl4=3.34 and pl5=5.1 v also the same before and after pressing power
the only thing that i get when i press the power button is a lighting led for 2or 3 seconds then goes off again, no fans no display at all
