I cant turn on my toshiba ultrabook

My ultrabook wont start or wont turn on and i dont know why, Ive been charging it for two days and still nothing happened.Because it is a ultrabook i can charge both at the same time or individualy because i can make the laptop a tablet if i wanted to, the keyboard part (when im charging) seems to have a white light but the tablet part (even when im not charging) it keeps blinking an orange light... please help
