My Hibook pro won't turn on and the light won't signal when I'm charging after trying combinations of volume knob and power button

Hello. I have a problem with my hibook pro.
Since yesterday I try to turn on it is only the keyboard that turns on and off so early.
When I charge it, the light that signaled no longer signals, but it is always the light on the keyboard that lights up once and goes out.
Before that. I had tried combinations of the volume knob and the power button that I remember more.

I would really like you to help me solve this problem. Thank you for answering me
