Toshiba charger light on but wont turn on

So today i went on a long trip to san diego, so i stopped at a hotel and i decided to turn on my toshiba to play some games, the toshiba was dead so i got out my charger and plugged it in but it still didnt turn on. I noticed it was exposed to the sun when i was driving and some blankets were on it. (my toshiba model is the satellite C855D-S5340). Ive tried the tutorials on my ipad to try to get it working but none of them worked. Could someone please help me?
