Bricked P50?

[MoonDrive]

Hi there! Im new to the forum, so sorry if ive posted in the wrong topic or whatever lol.

Ill try and explain it with as much detail as I can;

Yesterday, I opened up my P50 to look at the screen model number. Everything was fine, I didnt break anything, and i got what I needed so i put it back together. Tried turning it on, and i got the RAM error beep code thing. No problem, I thought, ill just reseat the ram sticks! .....nope. Turns out unplugging the trackpad and fingerprint cable fixed it which I thought was strange. So, it was up and running fine, I turned it off and plugged it into my external monitors, and the whole thing is now completely unresponsive. The power LED comes on, fans spin up for 2/3 seconds, but nothing displayed on the screen at all. No matter what. Ive tried reseating the RAM, taking out the CMOS, ive even swapped out the NVME and SSD. The RAM does work by the way, I put it into my Legion and its all good. What else can i possibly try? Has it somehow bricked itself from me simply plugging it into my monitors / charger? I dont physically see or smell anything if it is the charger but I doubt that as, again, it works with my Legion. Did the BIOS somehow mess up? Will I needed to reflash it somehow? Im not very good at soldering and dont trust myself with not breaking it more. Hopefully someone can help me with this haha

Have you tried leaving it so sit in the comatose state for several minutes?

These laptops go through a long, disconcerting self-test. If it remains comatose after several minutes, more diagnostics is required.
