ok battery working with dsdt patch and kext, but i have problems with HDMI, monitor works nice (nvidia web driver), if i plug in hdmi cable, the screen jumps to the connected TV (everything fine). BUT: my laptop screen gets black, even if i unplug HDMI cable the laptop screen is black, only way to get back screen is plug in hdmi again so the screen is on my TV, restart laptop and unplug hdmi, then i have screen on laptop again. (also in settings -- monitors) i have no option to use 2 screens, extend, mirror etc
