I have same problem too.

Touchpad not enable by pressing F11. I installed all of drivers but still not working.

I upgraded BIOS version to A11 but still not working.

So I downgraded to A10 but still not working.

Keyboard backlit is not working too but keyboard can type.

I can find my touchpad on device manager but it's not under "mice and other pointing devices"

I found it under "System Devices".
