HP CQ42
Board No- DAOAX1MB6H1
Found liquid on charger and vcore section.
Work done:
1.Clean the motherboard.
2.Check for shorting. (Found upper charging FET is short so replace this)
3.Powering the MBD. Laptop is on but no display
4. Check power rail found no vcore.( VIN is not present on pin 16 of ADP3212...........get PR46 open therefore I replace the 1K resistor)
Now laptop is working fine.
