Hi
I just got a HP EliteBook 820 G4 HSN-I01C 6050A2854201-MB-A01 i5-7200U with liquid damage. At the first check, the motherboard was short with no led light! After checking the motherboard I found a fired chip indicated in Area#1. After cleaning it, the short from the motherboard disappeared and the led light was presented, but not power on!
After second checking with 19,5V presented on the board I found a chip very hot indicated in Area#2 as needing to be replaced.
Can someone help me with a schematic for this HP? Or maybe some one help to find out what kind of chips I have to order for Area#1 (I have no info about it) and Area#2 (on this chip is noted as 1U=B1M but I can not find any info about it)
Please find attached all 3 pictures!
Thanks
