No touchscreen. Fn + Brightness combination does not work. Fn + Volume and media control buttons do work. Fn + Screen On/Off works. Fn + Airplane mode does not work. On hibernation touchpad becomes unresponsive. Some say boot some parameters fix it. It did not in my laptop.

### Graphics

One can Install Nvidia binary drivers to use the Nvidia card. Tested with nvidia-367. Works as intended. One can use the binary driver's PRIME function to use either Nvidia (High drain, high performance, no hardware video (h264) acceleration meaning vdpau is not accesible? [1] ) or Intel (low drain, hardware video acceleration(h264).

### Webcam

Works out of the box.
