Good evening friends of the forum. The customer told me that his laptop fell on the floor and cannot be powered afterwards. Looking at the motherboard, I find no obvious signs of pcb breakdown. Doing some measurements, I find 3.3V and 5V on two coils. Absorption is so low that the bench power supply does not read them. I tried to reprogram the bios, tried a reflow on the kbc bga but nothing. If I connect the battery, no charging LED lights up. Connecting the battery and the power supply I find a very low voltage on the pins that recharge the battery (0.84v)
On the battery connector I find two pins with 3.3V.
