Hello friends of the forum.
This laptop enters with the following defect:
When I connect the power supply, the power supply presence LED lights up. When I give the power on, the second led turns on, the paint turns but after 10 sec it goes off. I have no image on internal screen and on vga.
Tried to change ram, cpu, bios reprogrammed, but nothing.
I measured the voltages on the coils and they are present including the Vcore CPU:
PL5 5,18V
PL4 3,38V
PL7 0V , AFTER POWER ON GO TO 1,81V
PL6 0V AFER POWER ON GO TO 1,07V
PL11 0V, AFTER POWER ON GO TO 0,92V
