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.

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?

I hope my computer does not randomly reboot while typing this. My main system is the AsRock 970A-G/3.1 motherboard with the AMD 8150 chip. I am experiencing FREQUENT and RANDOM reboots once the system is used for a couple of hours (sometimes it reboots before I even get to the Win7/Linux Mint dual-boot screen). The problem MIGHT be the DRAM controller chip (I recently upgraded to the maximum 64 GB RAM). It also might be the VRM chips. I am using a typical aftermarket CPU cooler, which does NOT blow air DOWN onto the VRM heat sink.
(After previous generation hardware [Gigabyte] didn't...
