Hello, I installed the new bios (216) for this laptop and after that I installed ubuntu 14.04 (with nouveau.modeset=0 ) and nothing has changed. Touchpad is not working, wifi card is not detected (this can be fixed easily), sound card is not working(this is a new error!!) Regards, 2016-02-10 22:50 GMT-05:00 Hendy Irawan
