Toshiba Qosmio F15-AV201 will not turn on

Question

I have a Toshiba Qosmio F15-AV201 and for some reason it appears to be in hybernation. If I take the battery out and put it back in the system indicator light will turn green but as soon as I hit the power button the light turn yellow and begins to flash. The system will not turn on at all. Please help.

I tried all the things you suggested to another person but still does not work.
