EDM-020 motherboard, can anyone identify what the missing component is so I can order another, and perhaps what it does? It is on the liquid metal side of the board, opposite end from the ports.

Hi all, Im working on a board, that my customer brought to another shop, and smeared liquid metal all over the board.
The laptop powers on, then shuts off. I noticed traces of Liquid Metal near the edge of the CPU, but I fear some maybe underneath.
Has anyone ever tried Ultrasonic cleaning, or compressed air to remove or agitate the liquid metal?07-11-2025, 01:47 PM -
Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
hi just a few days ago i had a VERY similar thing happening which led me to this forum, ie this post!
it all began with me applying liquid metal to my probook 430 g4 7200u AND buyin a backlit keyboard on ebay.
after few hours everthing went well. plus then i ordered myself a new hdd door, some 16gb ram, etc.. a new FAN, the old was too loud, etc..
so i ended screwing on my laptop few more hours opening and closing.. in this procedere TWO things happened:
some lquid metal escaped and was teared around the bios chip , special not on it but on... -
Hi guys,
I have this UX534FT motherboard with some resistors damaged by liquid. Can't find any schematics.
Could you identify the value of selected resistors please?

Hi,
I'm fixing a GPU card for a streamer, was sent to me by mail. A shorted cap on a power rail has severely burned the PCB.
As you can see from the darkened PCB around the mosfets there are signs of liquid damage. But it's odd because the person says no water has entered the PC cabinet. If you spill something on a desktop you would know I guess...
Funny thing is that the liquid is not only on the PCB but on top of many chips which are tightly covered by thermal padding under the heatsink, even on top of some of the RAM chips
