No touchscreen. Fn + Brightness combination doesn't work. Fn + Volume and media control buttons do work. Fn + Screen On/Off works. Fn + Airplane mode doesn't work. On hibernation touchpad becomes unresponsive. Some say boot some parameters fix it. It didn't 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.

It has got one free ram slot that is easily accessible using the RAM bay.

BIOS

User can disable Secure Boot. User can't disable Intel HT There is a choice of compatibility mode, it was accessible at first boot. I set it do enabled some time and disabled later. Now it is grayed out(?). User can disable AES-NI User can disable Intel Virtualization.

Battery

Design ~37Wh, Usable ~35Wh ASUS Battery

Thermal

There is a fan that can turn itself off. Sample sensors output while on batter doing light web surfing.
