ANX1121 near LVDS -cold joints .. It is weird, but it was the problem :-) Resolder and works perfect.

New info:
The issue is 100% mechanical.
When I press the board underneath the RAM slot, the laptop works fine.
As soon as I remove my hand, it shuts down.

It looks like there’s a cold joint or cracked trace in that area.
Any advice on what component might typically cause this on an Asus X553MA?

Thanks in advance for any help!...

Hello,
I have a problem with an Asus X553MA motherboard. Sometimes the system works fine, but other times the CPU voltage drops to 0V. In most cases, the laptop reboots after a few seconds due to the voltage drop.
Occasionally, it shows the ASUS logo or boots into the BIOS. Sometimes it can stay in the BIOS for hours without issue.
I checked the board with a thermal camera, but I couldn't find any overheating or leaking capacitors.
Unfortunately, I don’t have access to the schematic.
It seems to me that when I bend the board, something changes.
Could this...
