The full story can be found on my post here
To sum up:
The built in keyboard and touch pad does not function. I can only use external device(USB keyboard and mouse).
Soon after successfully logged into Windows, I got WORKER_INVALID error message and windows forced me to restart. The message disappeared once I uninstalled ASUS Smart Gesture driver.
The newest driver for ASUS (ASUS Smart Gesture and ASUS ATK Package driver) does not solve this. I could even adjust settings for touchpad in ASUS Smart Gesture panel, yet my touchpad did not response.
Even stranger, when I opened the computer, I can use my keyboard and even type in the Linux grub shell. But once system got loaded, both in Windows and LinuxMint, the keyboard and touchpad stop functioning.
Now I suspect my BIOS went wrong, but I am not sure and dare not update the BIOS so rashly. May anyone suggest anything?
Update: At last I went to the repair center and got the notebook repaired. It was a hardware failure but the people there did not explain much to me.
