Hello.
The laptop was working well on battery but not charging. Died as the battery drained. Adapter attached no reaction to power button.
PQ101 18.5 v on S,G and D
PQ102 S,G= 18.5 D=1v
PU101 (ISL6251)
VDD=5v
DCIN= 18.5v
ACSETIN=1.4v
ACPRN=0v
EN=0v
VREF=2.39v
PQ107
Pin 1,4=0v
Pin2,5=3.3v
pin3,6=0v ( PR109 and PR116 = 18.5 v on Vin and fet side but 0v at PQ107 side )
Changing the resistors still same voltage???
Shorting the S and D of PQ102 the plate works normally.
Are the resistors to change again or somewhere else to look?
Best regards.
