    Hi, several days ago i disabled one of the gpus in my m18x so i can use it with a 240w charger. Today, im unable to enable the second gpu again, it dosnt appear in the system specs, neither is recognized by the bios. I tried to reinstall drivers, but it didn't worked. Do you have any idea?
    (now im with the 330w charger)

    Is the 330W AC adapter correctly identified in the BIOS when connected?

    - Try doing a power drain.
    - If that does not work, try clearing the CMOS.

    Power Drain:
    • Remove system battery
    • Disconnect AC adapter
    • Hold power button down 30 seconds
    • Connect AC adapter
    • Load Windows
    • Install system battery
    Clear CMOS (Non-Haswell Systems):
    • Remove system battery
    • Disconnect AC adapter
    • Remove bottom cover
    • Hold down power button for 30 seconds
    • Ground yourself to the motherboard by touching a screw on the chassis
    • Disconnect wire from coin cell battery
    • Touch screwdriver tip lightly against pins the wire connects to for 1 or 2 seconds
    • Reconnect coin cell battery wire
    • Connect AC adapter and power up
    • Press F2 to enter BIOS
    • Set date/time and any of your customized settings
    • Press F10 to save and exit
    • Load Windows
    • Install system battery
    Note: your system may start beeping after clearing the CMOS. Don't panic. Hold down the power button to shut it off. Turn it on again, and it should restart and clear itself by resetting BIOS defaults. If your OS was installed incorrectly with the BIOS set to AHCI instead of RAID, you may need to manually set that back to AHCI in the BIOS for Windows to load. If you have a Haswell machine, see the link at the end of this post because this method won't help you.

    Clear CMOS - Alternate Method:
    • Remove system battery
    • Disconnect AC adapter
    • Hold down FN key and power button simultaneously
    • While they are still depressed, re-connect the AC adapter
      (This has never worked for me, but some folks swear it works for them.)

    That's because I was not done with it yet. Read it again. ;)

    I hope that works for you. Please post the results.
