erm, be frankly,asus warranty for notebook no that bad lo... got one unit ux301ln got hdd noise and send it to warranty, including courier time (they pay for courier fee), one month, help you to do stress test, change hdd, change fan and heat sink (since they though noise came for fan?) quite reasonable lo... (really personal experience, and i am not doing advertisement for asus, it doesn't pay me anything, just want to make something clear)
