Hello everyone I have an ACER Laptop NITRO AN515-57 51k6 there is no indicator light when the mains is present (240v in France) the 19v is present at the charger output I changed the battery still the same problem! After opening the Laptop on the motherboard we can see a burnt component (probably on the power supply line) 5mm on the side 4* 5 pins! On the top we can read "BABEFM"(just above connector JRTC1) !! any idea of this circuit! Does anyone have the schematic of this LAPTOP !? Thanks in advance to all !!...
