    So I'm a bit shocked right now. I'm not sure if anyone is aware of this.

    I've been using cowboy's bios patch + latest nvidia 330m driver for a while now on windows 10, but I just found something really interesting.

    As usual, every feature update breaks my nvidia driver, requiring me to reinstall every update. This time, I just wanted to try and see what would happen if I tried to install the original hybrid graphics driver it came with for Windows 7. I have set the bios settings from dynamic to auto with test mode disabled...

    ... and the switch is working... including the auto brightness. The auto brightness and the brightness key on both stamina and speed are working! I can switch from speed to stamina, but the screen goes black, requiring me to simply put the laptop to sleep and wake it back up (no need to reboot!) I can switch with no problem.

    Did Microsoft fix the driver compatibility after all these years?? I find this hard to believe, but it's working, right in front of me. This means bios hack is no longer needed to use the nvidia chip anymore on Windows 10 for this laptop. Huh.

    Does restarting the graphics driver with ctrl+win+shift+b avoid having to standby cycle?

    Or using the Windows Power settings (old Control Panel) to reprogram the power button (or standby shortcut, if present) to turn off the display, would that work, too?

    I just tested it and I can confirm that method works. I don't need to put the display to sleep in order to switch.

    But I've noticed that once it's switched from speed to stamina and I use the shortcut to reset the graphics display driver, for some reason it sometimes won't go to speed mode. The popup shows, but nothing happens. It's similar to the bug that also occurred occasionally on windows 7 where the button would be unresponsive but the switching warning would popup. Speed>Stamina>sleep>wake>switch works with no problems, however.

    On the side note, brightness change doesn't work right off the bat, but it starts working as soon as I open the notification panel by using Windows key+A, which is no biggie.

    Despite all these bugs, it's refreshing to see the autobrightness and hybrid graphics working again on the latest windows.

    I am just finished clean win10 installation (without bios hack). Could you tell me which "original hybrid graphics driver it came with for Windows 7" I must install for STAMINA/SPEED/AUTO switching working

    thnx, Zoran
