Created the EFI by using the Dortania guide.

HDMI has display but no sound, still not fixed, hackintool reports that I may have to spoof audio device id idk.

Battery indication works, my battery is fairly old so I get about 1 to 1.2 hrs of use on half brightness, 40 mins or less if i crank up the brightness and sound playing music.

Keyboard works, volume key is mapped properly and brightness control works, by pressing Fn + K for low and Fn + P for high.

Touchpad works properly with some of the gestures disabled on settings.
