[Ipart]

Hi,
Motherboard start only when reset BIOS by take off battery and then working normally. But if i turn off laptop then try again turn on only black screen. I replaced and reprogram KBC. I replaced and reprogram BIOS. CMOS battery is 3,1V. And still the same. What could be the problem?

ok , if one component like gpu have problem , that error save in bios and in next restart , bios prevent boot completely . so you must check all component like : dvd , hdd , wifi , vga , ram . ex: try convert dis to uma and test .
Of course, if you are sure of the BIOS file that you are programming . so i sugest you to sure bios file , send s/n of laptop to me and i create new bios file and you reprogram it and test .
