    Hp 15-dy1731ms MB DAG71MB16D0 Rev C No Power

    I am working on this Hp 15-dy1731ms MB DAG71MB16D0 Rev C, not Powering on. I get 3.3V on the ON/OFF assuming that the IO chip is good. Attaching the Original BIOS. If someone can rectify this, I would really appreciate. BIOS is programmed to Winbond 25Q128JVSQ. Thanks in advance. NB S.No: 5CD93761V8 Model 15-dy1731ms

    I found the BIOS from the Hp site. Got the BID info from Original BIOS "086C8" which is for my model, Can anyone inform me the end offset length that has to be copied to the new BIOS... Thanks in advance.

            Sir, "hoaca388" thanks, I have got this same BIOS 086C8 from Hp site & you even send me thes same as an attachment but I think no Dmi : 480000 -> 4810ff & Win key : A9E000 -> A9E03F information are updated. Kindly inform me how to do it or pls. do it for me. I programmed the chip & now I see life in the board, the White LED on the DC-in jack blinks for 3 sec & then turns off. Thanks

                  Hi "hoaca388" I re-programmed but still the same, I press the ON/OFF switch & the white LED on the DC-in jack blinks 3 times & then shuts down. This happen when again the switch is pressed. I think problem is in the motherboard. Anyway I have opened a new thread "https://www.badcaps.net/forum/showthread.php?t=105397" , kindly if you can share some tips & experience of yours in there. Thank you very much.
