    CONFIRMED: Works on Alienware m17, downgraded from 2.5.0 to 2.0.4 which allows undervolting and now i can undervolt without issues (apart from that the undervolt does not help much).

    I've downgraded many times, make sure you unblock any file you download first! Right click on the file, go to properties, then hit unblock from the bottom if it was blocked. To stop this stupid auto blocking of files for good, see: "Are you sure you want to run this file?" [Yes or No]

    Here is what I recommend:


    a) Uninstall Alienware Update AKA Dell Update and Dell SupportAssist otherwise they will keep nagging you to update your BIOS.


    b) Flash the BIOS using the Recovery USB which you created using the guide I showed you earlier.


    c) Immediately head into BIOS and make sure you disable Firmware Capsule Updates in the Security tab otherwise Windows will immediately upgrade your BIOS!


    d) Once you're back in Windows, reflash the same 1.5.0 BIOS again but in Windows, I had to do that last time as I was getting weird behavior (I can't remember what exactly but once you have flashed 1.5.0 in recovery mode, you will be able to flash 1.5.0 again through Windows since you're not technically downgrading anymore you are just reinstalling the same BIOS) so do that to ensure the BIOS is 100% flashed correctly.


    e) The moment the BIOS is flashed, go back into BIOS and load setup defaults then save and exit (from the last tab in the BIOS)


    f) Now enter BIOS again, set your battery from Adaptive to Custom and tell it to start charge at 50% and stop charge at 90%. This will ensure the battery is never over charged and will thus prolong its life.


    g) In the 2nd tab in the BIOS, I recommend turning OFF Power Share as that will drain your battery if your laptop had a USB device that needs power overnight (such as an external HDD or Game Pad)


    h) While you're in the BIOS, ensure that Firmware Capsule updates are OFF

    Is there anyone who is able to edit a newer bios and stop the thermal throttling? so one can keep the security updates and new features like the better compatibility with new graphics cards in graphics amplifier? As if I do travel I dont want this problem of the graphics card throttling so easily.

    So I might be forgetting but does the earlier BIOS let you go above 87*C on the GPU?

    1.5.0 will let you go above the new thermal limit of 75c, which has been set in pretty much every BIOS post 1.5.0.
