    I got a similar notebook and save the bios image. I wrote to the original notebook and still the same problem. I can read back the image from the eprom, it works fine but the notebook still won't power up. The another notebook done the same update to the version 1.14.. I just catch a glimpse of the flash and it made a type c controller ic frimware update... Maybe it could be the case with the original one, that it fked up the usb controller update???

    I tried it but no success... The capslock lights up for 2 sec, the charging port led blinks 3 white short, 1 long amber, 3 white short. I tried to reseat the memory, and other modules. I think its a bios issue, it charges the battery, and i got 3.3 on the power button, and 5v is ok too.

    The board number is DA0X8BMB6G0 rev. G.

I tried to reflash the bios with an external eeprom writer, but no success. I tried the factory provided Q85 bios, all the bios i found on this site, i also tried to flash the 430 g5 bios too. Please help what else should i try.
    Thanks
    Post your original bios backup or the corrupt one if you have it.

    HP 14s-fq1010nm Black screen after BIOS update - cannot downgrade
    by mitchw
    Just had a customer bring in a HP 14s-fq1010nm to do some maintenance.
    After updating the BIOS to the latest (F.35) I get black screen (no backlight turning on). However the backlight turns on if I connect an external display to HDMI, but when booting to Windows, both displays remain black.
    After disconnecting internal LCD, and plugging in external display via HDMI, it works on external.

    I tried downgrading it using official method - using an USB drive with older BIOS version, but it fails, saying that the BIOS files are corrupted. I used about 5 different older BIOS versions...
