    If it was good before flashing the BIOS, chances are it's the wrong image or it's corrupt.

    "HP 820 G3", and only that, doesn't really tell us anything. Theres an i3, i5, i7 or even an AMD board, each with different BIOS. And different revisions for each that could have yet a different BIOS. Need to be more specific. For example:

    I have the board 831762-001 from an HP 820 G3, i5-6200U, and flashed this file with MD5 cb229e609f1ebd3d56e4da05cc2f6645.

    With the provided information we can't even know which are the schematics you need

        Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
        by Tynan Dill
        I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

        Upon bringing it home and plugging it up, it showed a standby light.

        I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

        The screen seems to blackout and stay black, but with a flashlight I can see the display.

        With my Playstation 4 connected via HDMI, and running a game I can hear sound.

        Assuming...

        Intel Arc A380 videocard power limit remove - BIOS needed
        by iulik17d
        Hello everyone!
        The Asrock A380 low profile card (ID 8086 56A5 - 1849 6006) have an power limit of 45W. Intel removed the possibility to increase power using the software utility, anyway the card is in an proxmox machine that doesn't run windows.
        The same hardware is in another form by the name Asrock A380 Challenger that have the same VRMs and the power limit is at 60W. I searched online and found on another website an .bin bios file from the Challenger variant, that I flashed using an CH341a. Flashng worked well, I put the card in PC and booted. GPUz shows that new device ID is 8086...

        After flashing bios, no power, nothing comes on ASUS K56CB
        by cyrgh
        Hi
        LAPTOP model: ASUS K56CB (i7-3537u cpu)

        BIOS POST took a long time, more than 30 seconds, it was never like this before. I decided to flash the bios using AFUDOS.exe.
        I downloaded the original BIOS file from Asus site ver205. I used RUFUS to create a boot-able USB flash having this command in AUTOEXEC.BAT:
        AFUDOS.exe BIOS.ROM /GAN

        It read the bios then gave the warning about writing to bios may ruin it. I confirmed and as soon as I pressed the enter key the power went out and it doesn't power on anymore. Even the battery power light does not turn...

        Microsoft Surface Pro (5th gen) model 1796 - no power
        by PantherDave
        Hi all!

        I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

        I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

        HP Omen 15-dh0052nf power-on & bios password
        by Nopslide
        Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.

        My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).

        Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set....
