Another HP 840 G2 Motherboard Repair with a Unique RAM Chip Fault, From a YouTube Viewer

In this Video I diagnosed and fixed a fault HP EliteBook 840 G2 motherboard that could turn on fan spin but show no picture on the screen, the problem was a fault RAM power supply chip that got damaged by water. The RAM chip was giving out 0.6V which is abnormal, I checked other power input pins that should have 5V and discovered 1.2V. This prompted me to replace the RAM chip which then solved the problem.

The laptop was brought by someone who watched another 840 G1 video I uploaded here 2 years ago. The link to that video is below.
