    hi guys,
    I need really your help!

    my notebook HP G62 -B35SG .
    issue: wrote wrong BIOS, now after start there is only black screen.
    after remove the battery of the BOIS for 1 hour, it shows bios error 502, and black screen again.

    i tried with key win+B, but it does not work.

    how should i do to write the original BIOS?

    I have to say that my knowledge on BIOS matters is probably less than yours. Considering this please read this which may be (OR NOT) of help to you.

    Good luck!

    Again: I really don't know much about BIOS or your notebook so I'm sorry if I cannot be of more help to you.

    what i done:
    1 download the HP Unified Extensible Firmware Interface (UEFI) Support Environment ----yes done
    2 Execute this under windows and create a HP_TOOLS UEFI boot usb stick -------yes done
    3 download the BIOS for my laptop from HP, it is a exe file, extracted it, there is a 01439.fd file,
    i copy it into Hewlett-Packard/Bios/Current, and rename it as 01439.bin, and 01439.SIG
    4 Shut down the laptop, plug the USB stick, hold win + B and power on

    nothing happend , did i do anything wrong?
