Hi everyone, I need your help guys, how can I fix may Asus 5XXXI laptop, it's a brand new laptop then, I never use it everyday since I bought that laptop, may last use on that one week ago, then now I open it but it's no screen appearing, but I tried to plug in the cord and the battery and the bulb light are functioning, what I can I do fix it?
 


Yes possible it's the LCD. Unplug the power cord and then remove the battery. Then reconnect the battery and power cord and power on again.
