msi gx710x ms-171a won`t boot sleep mode?

hy guys
i have a msi gx710x with ati2600 video card (512 mb).
the problem with this notebook its that when i press power it will start (no signal) but the only light that i will see its the blue from power and a orange one with a half moon (sllep mode?).
i swap the memory,charger remove all the stuff from the notebook (only basic on) but nothing will do.
i try everything even the "oven trick" wint the mobo and video card and the same.
any one repaired a msi?ty
