    Brightness adjustment is always working on my M6700, I have a regular eDP panel, which the GPU can communicate with no issues, while the PremierColor lcd is not a regular eDP panel, it is a 50pins display working with only 40pins effective out of the motherboard I think this is why you have issues with brightness adjustment, you should get a cheap 17.3" eDP 40pins display and a "3D cable" to check this out.
    Brightness adjustment is working on the 86.04.2B.00.02 vbios, on the 86.04.67.00.03 it's not working, might not work for the other too, I did not checked if it was working on all vbios/desktop vbios
    So far this is the result from the tested bios, keep in mind that any legacy oprom are disabled and only UEFI is enabled

    The 214674 might work if I update my M6700 bios, I'm still on the A19 which is older than 214674 vbios, just saying.

    If someone got an another P4000 vbios (86.04.A7.00.04 or 86.04.2E.00.0C), please share it :)

    You are tempting me for getting a P4000 mxm, seriously!

    But I think you will still get brightness adjustment issues if you keep the Premiercolor LCD and the performance is around an overclocked GTX980M

    Problem is, the GTX 980m is such a power hungry card. And I have had 3 failed 980m already (maybe I've damaged the capacitors when soldering on the extra mosfet). with 1792 CUDA cores even locked at 1257Mhz 980m will be no match to it regardless of how much more it's overclocked. :/

    And, if it's not the Premiercolor LCD, I might well just get a thinkpad P53 with RTX 5000 and 6 core processor and 128GB RAM capability

    Yes for sure, the P4000 consumme about 65~70w.
    Do someone know how to trick nvidia driver to install "desktop" drivers for a laptop card ? I know they are the same package but I believe it could be the only way to get the boost frequency working with thoses desktop vbios :/

    All cards supported in the package get the same driver (exact same nvlddmkm.sys file), just with some different settings set at install time. I rather doubt that a different driver will kick the speed up if there is a limit set in the vBIOS.

    I tried P5000 vbios which GPU-Z says should boost up to 1500+MHz but I was stuck at 1252MHz, I even modified the P5000 vbios to match P4000 PCI ID but it change nothing.
    Maybe nvidia drivers initialise the P4000 with a vbios that isn't on the card ? like windows using newer intel cpu microcode without requiring a bios update ?

    If that were the case, wouldn't all P4000's not boost?
    What does GPU-Z "PerfCap Reason" say when you are getting stuck at 1252? Could it be hitting the card's power limit?

    The card isn't near it's power limit, look at the screenshot
