    Connect an external monitor to test the display

    Turn off the unit remove CMOS battery and if possible RAM and place it back after 30 min and check.

    Still if the issue happens than reply.

    Thanks for the reply.
    External monitor: no image
    Remove batteries: no results

    I hope you can give me some other solution, thanks.

  • How did you downgrade? What file name in bios was placed? For example: xxxx.fd

    Edit the platform.ini file line: "VersionFormat=XN.NN" to "VersionFormat=XN.DD"
    Save and run H2OFFT-W.exe

    That is all :(

    I went to a store where they have the same laptop, turn off and press FN + ESC and start in recovery mode, so I reached the conclusion that after the downgrade also died the recovery mode, any ideas?

    I think if I could reboot the CMOS with the jumper pins, it would work, but I do not know what those pins are on my board.
