I have TP410UA 2.0 that will not respond at all on battery. with power attached, power and caps lock light up but no charge light or fan and no heat build up even after half an hour. nothing on the display or hdmi. the only response at all is the two lights that are on while the charger is in will turn off after a 10 second hold and stay off until they are released then they go back on and stay on. I am hoping for an explanation and if possible a way to resolve if im lucky. Thank you in advance for any assistance!
