    I am having this problem with my Pavilion dv7: CAPS & NUM Lock flash twice.

    My laptop has no battery, no hdd, is powered solely by being plugged in. I have unplugged it, forced shut down (by holding the power button) waited 30 seconds, 60 seconds, 2 minutes, etc. and the screen remains black. I have also removed the BIOS battery (1 day).

    Since the screen is black, I am not able to run any of the Fx suggestions, or any other type of startup.

    I tried several times Windows+B combination with two usb sticks, the last one... an old USB stick with 128MB formatted as FAT16 and with HP_TOOLS installed. The BIOS file to flash is 3635F12, extracted from sp46804. I tried also with the oldest sp45171 and his 3635F03.FD bios file renamed as 3635.BIN, 3635.WPH, F03.BIN

    After read those 31 pages of posts, I did a lot things with PhoenixTool219, but I did not get any sig file.

    I tried with 3639.BIN after read about numbers under battery too.

    HDD still has originals partitions (4): Windows, Recovery, HP_TOOLS and System.

    Can you HELP ME?

    Product: VT360EA#ABE
    Model: dv7-3020es
    Under battery: REV: 3639-200

    Thanks!

    Thanks for responding.

    I have to admit I'm afraid of putting the motherboard in the oven despite two blinks, which HP claims to be from the bios. I think I have to put the oven at 190 degrees Celsius for 10 minutes.

    Do you think that will work out?

    Thanks.

    it works. only issue with this board is its very thin so it warps and chip comes loose on some pins.
