    Hp probook 440 G5 - black screen after windows bios flash

    Hi. I need some help. I got a HP probook 440 G5 notebook for repair. The windows made a bios update, the it didn't start, just black screen. 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

          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.

              If i write this image, then the led at the dc jack blinks short whites and a long amber. Still not working, please help. I can't understand why the factory image won't work.

                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???

                                        Hi all. HP 440 G5.
                                        Laptop without memory - beeps that there is no memory. Inserted memory. Black screen and nothing. Then the cooler starts making noise. I'm guessing the BIOS is damaged. Can you help? Thank you.
