I just got my Asus ZenBook UX305FA through ebay today. I plugged in my charger and tried to turn the computer on. The Led light for the power button turned on, but there is nothing displayed on the screen. Also, I tried to take off my charger and turn it on, but the power button won't work. I can't do the thing where I take out my battery, because on the zenbook it is really hard to do so. I don't have a small enough screw driver to open it. Any tips on what to do for either one of these problems?
