Hi everyone,
No idea about the backstory here.
Doesn't look like water damage as all the indicators are white and I see no marks at all on the motherboard. The motherboard has most likely never been removed from the case, but the cpu cooler has been before (Noticeable because the little rubber on the fan was not sticking on anymore). There was not a lot of paste on there so I replaced this for good measure but it did not solve the issue. I don't think this could've caused any issue because even though there was not a lot of paste, it did have enough paste not to destroy the cpu.
The battery in this system is not original, but from a different company called LMP. The battery works fine
The system boots into the OS but after a while (sometimes 10 seconds, sometimes a couple of minutes) it just powers down all of the sudden. No warning, it just goes back to S5. The charging light stays consistent (no SMC reboot). In some rare cases the system does not respond to the power button anymore after this happened and the charger needs to be reconnected to get it to respond again. This is with the battery holding enough change and keeping the S5 and G3H power lines up so the system does not reset or anything.
On battery the system pretty much always works but powers down randomly, but with the charger plugged in there is a random 20% chance of getting 3 beeps before the system powers down again.
Where to look in this case? To me it sounds like the 3 beeps are just happening because something is going wrong with the CPU and that happens to be while the memory is being initialized. PPDDR_S3 is stable at 1.34V
EDIT: The hotter the system is the bigger the chance of it passing POST but powering off right after or sometimes even while the "dong" sound is still being played. Not sure what this might mean though. Cracked solder joint? After the system crashed off it can not be powered on again (the SMC does not respond to SMC_ONOFF_L)
EDIT2: Seems to be the PCH thats overheating
