I got a Toshiba Satellite C55-C5270 in December 2017. Has worked great and been well taken care of. Suddenly, I try to turn it on and nothing. I've done the whole unplug the battery, hold the power button thing, nothing. I've even tried hooking the ac power cord with no battery attached, nothing. I get no indicator that it is even charging when I plug in the ac power cord. Help meeeeeee!!!! Lol
