In short. I have 2 samsung laptops, both broken. Both have been opened before. One is stripped of everything besides the essentials (mobo, cpu, ram, etc.) and the other is fully reassembled.

MODEL: NP350V5C

The fans turn on for a brief second then off and then just stay at full speed forever.

Things I've tried:

repasting,
waiting for it to turn on
the stripped one got the oven treatment (still nothing).

Please help

Oh the oven one still beheaves similarly, it was all covered in aluminum foil except the gpu die (which I thought is the issue)

There is no caps lock light but the dvd drive starts reading if I put something inside. The screen doesn't light up at all, the charging and the power lights are on, no blinking.

Ok, Im not 100% sure whats causing it but im going to list some things you could check

Check the connecters, are any connectors damaged? This also includes cables.
Are there any scratches on the motherboard or missing chips (may look like a silver metalic spot on the mobo)?
Are there any spots on the motherboard that get really hot in the first gew seconds?
Try switching out parts (like the power switch/button).
I notice you said you had two of the same laptops, are they a company laptop?

Overall I think this comes down to a motherboard failure caused by wear and tear on the systems, sometimes it may be cheaper to buy a new laptop than keep fixing a problematic laptop.

Nah they're not company laptops just the first one broke we bought another one.

There are missing components but its the same ones on both and they were missing when it was still working.

The one that is not disassambled into oblivion actually broke like that once and it fixed itself after sitting untouched for like idk 2 years?

Also the other one was able to turn on if you waited long enough but that was months ago and there has to be a better solution than waiting hours for it to start booting.

I'll check the heat thing later and update

"Sitting untouched and it fixed itself" have you tried disconnecting the both the normal battery and CMOS battery? Once both are unpluged hold down the power button for 40 seconds. That could work.

YO THAT'S ACTUALLY A GOOD IDEA! Ill try that. Wouldve done it earlier but the way the cmos battery is mounted is a pain.

Ok this is bullsh*t I tell you I removed the cmos but it still did the usual..And later I got the stripped one to boot on me when the fan was unplugged. I am trying to replicate that now.
