I've gained this ASUS laptop me 4 weeks before unfortunately the left speaker and the ASUS logo backlight was broken due to which I have returned the laptop then summarily to ASUS and within a week I have then the laptop repaired get back. So I can not understand the negative experiences with the ASUS Support. The unit is super processed and also the touchpad is at least for me very well finished and everything works as it should, had probably been lucky. I can only say that I also have via the hum and crackle in the speakers but that one only perceives when all you put your ear to the cabinet and even then you have exactly so listen to me no reason the device to advertising Mieren.
