The power button on my ASUS TP500LA-AB53T laptop won't work properly. I have to press the power button on anywhere from 6 to 12 times and holding the power button down anywhere from 1 to 10 seconds and finally after trying several times the laptop will finally power on and this happens even after placing the laptop in sleep mode and I try to wake it up. Is this a hardware problem or a software problem? Any suggestions are greatly welcome. Thank you.
