Re: hp elitebook 840 g4 need password unlock
Soldering back the chip can be hard sometimes. In fact got some trouble at the beginning to solder it correctly as there were too many tin on the central attachment of the chip on the motherboard. So first remove as much tin as you can from the center, and add more tin to the leads place, then with hot air, solder it back and it should work.
