    G62-B15SV northbridge problems

    Hello everybody,

    Need your help on this one please. A friend of mine brought with problem no picture. Saw that it had the notorious 216-0752001 (amd cpu + external vga), so I have changed the NB with a new one. I am pretty sure that it is soldered very well. When you connect the ac adaptor it powers on by itself and fan turns at high speed then slows down. No picture on LCD / VGA output. Have tried other CPU. The original one was manufactured on 2010 but the new one 2014. Is it possible that it might need a bios update or do you have any suggestion?

    Thanks

      I have seen this before. Sometimes when the NB goes bad the BIOS gets corrupted as well. Try a BIOS reflash before anything else.

              Thanks for the link. Got lazy to search. My programmer can't recognize the chip so I guess it is off. I will order one and get back to you with the results.

                Hello,

                I have received the bios chip but the bios file wasn't correct.
                My mother board is PM_A_HPC_S MV_MB_V1 - 610160-001.
                Ι have found this http://1bios.ru/bios/notebook/hp/g-series/hp-g62-b14er after re-programmaning it the laptop powers on immediately with fan turning full speed, afterwards turns normally, with no picture on panel / external monitor.

                Any ideas please?
