Hi everyone, Please help with a bios dump for this board: Asus GL503VM-FY014T DA0BKLMBAD0 Rev D the laptop starts and initialize properly (I can hear sounds from windows), but nothing displayed on internal screen or from hdmi all the voltages on the CPU & GPU rises, tried another screen, cable checked, a closer inspection shows the lack of "EDP_VDD_EN" signal on U14 (using DABKLMB1AA0 boardview as reference).. no short-circuit found and all resistances on CN3 are in normal range.. Where to dig ? I'm suspecting the bios, please help with the correct dump for this board (DA0BKLMBAD0 Rev D) |

BIOS on asus is searched for by a sticker on the motherboard. |

This board doesn't have integrated graphics power for the processor, that's why I was suspecting the bios because some BKL boards has. all the lines resistances at CN3 and eDP channels are in normal range.. +VIN_BLIGHT = 19.27v +3VLCD_CON = 0v (EDP_VDD_EN = 0v) PCH_BRIGHT = 0v EC_DISP_ON = 0v PCH_EDP_HPD = 0v PANEL_ID1 = 3.25v PANEL_ID2 = 3.25v eDP lines measured at capacitors from source side: CPU_EDP_AUXN = 455mv CPU_EDP_AUXP = 455mv CPU_EDP_TXP0 = 240mv~260mv CPU_EDP_TXN0 = 240mv~260mv CPU_EDP_TXP1 = 240mv~260mv CPU_EDP_TXN1 = 240mv~260mv CPU_EDP_TXP2 = 240mv~260mv CPU_EDP_TXN2 = 240mv~260mv CPU_EDP_TXP3 = 240mv~260mv CPU_EDP_TXN3 = 240mv~260mv Where to dig ? |
