hello, i have an Acer A715-75G FH5VF LA-J861P laptop that won't start, 19V ok 5V ok but no 3V, enable2 (ENLDO_3V5V) 4V5, enable1 0V, can you help me please , I am not an expert, I looked at all the resistors and short-circuit nothing seems abnormal to me.
I changed the 3V chip (SY8288BRAC) three times but no result, it is well supplied with 19V5 but does not trigger the 3v
I attach the diagram for those who need it
Thank you for your help
(my english is basic sorry)
