I guess it's only here now. But you need 5 quality posts.

Hi. I have found some links to mobo schematics for gt683, ge70, ge62 and Haswell gt70.

May be useful for all GT models.

They're weird as hell compared to clevo's but still helped me.

No idea who uploaded them and how they got them.

Hi.
Here's what I do when I deal with a mobo that doesn't feel so good
Step 1) all the normall stuff: swap CPU (!), GPU, RAM (check all slots), HDD (!), battery, power supply, disconnect CMOS bat
Step 2) visual inspection of  mobo
Step 3) thermal imager (check microcontrollers for heating) when the mobo is off  but power is supplied. I use SEEK thermal. You won't be able to fix that yourself but you'll save time by not doing step 4 if this is the case.
Step 4) If step 3 shows no funny business, flash bios directly to chip using unbricker tool

you'll have to flash it normally afterwards if was the case
Step 5) if nothing helped find a repair service.

If you brick the mobo feel free to use the unbricker.

It's really cheap. But you need to test the clamp and programmer first. Mine had bad soldering. I fixed that.
Backing up your bios is highly recommended.
 

Hi. I guess you may need a specific vbios for the GPU that is compatible with your laptop. That's the only way to put a v.1.2 7970m from p150em into that laptop. 560m from p150hm doesn't seem to work with standard vbios as well.

Hi.
Many of us are discontent that we can't freely swap dell and clevo AMD cards (7970m  and new rx480 included) but it seems that I may have found some clue to this problem.
Few years ago I bought a broken p170em with some ugly black 6990m. It looked like it was baked in the oven with some cookies.
I put it in my p150em and it was working normally with all sensors, data, etc. No beeping, no turning off.
What I noticed was that the other soic8 chip "2" (apl-something) was swapped as well as the main bios chip "1".
No other components were swapped and, as you know, if you just flash the main chip it won't save you from beeping.
Unfortunately I sold this card as it wasn't powerful enough for me, but now I've ordered a rx480 that I can currently use only in my gt70 and  I think it gives me some clues how to put this thing into a clevo laptop.
Does anyone have any Idea what that APL-somehing chip is and does it have its own firmware?
