    Need bios HP G42-458TX

    Hi, does anyone have the bios hp G42-458tx.
    Code: DAAX1IMB6A0 REV A
    Ci5 480m, vga ati radeon

    I accept the notebook can be turned on, but only a black screen. I've checked the voltage at the coils, all the good measured. I touch on HM55 cold, as not to react. cpu and ati touched feels quite warm

    I've done several things, among others:
    replace the RAM is still good, does not solve the problem.

    try to flash the bios main, with bios downloaded from a forum then HM55 gets warm. does not solve the problem

    so I conclude this might seem a mismatch bios or corrupt, and hopefully not the chipset or vga

    I attach the backup bios and bios downloads

        thanks for all your response

        before reading your response, I have several times tried to put the bios of which I found on the web. and did not change anything. in desperation I returned the original bios to be returned to the user, I try to turn it on once again ... it can appear on the screen.

        so the case has been resolved, although the record cpu and vga experiencing excessive heat, as weakness HP in general we know.

        little notes that I made,

        - Bios backup still good, for database badcaps
        - HP laptop does not directly display the boot
        screen, before pressing the power button, we have to press F9 or F10 to force the HP boot via an external monitor.
        - We also need to install the hard disk even if bad sectors, or which can be bootable usb

        thank you for your attention

        I love this forum

          🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
          by macabook
          Hello everyone,

          I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
          🧩 Initial Issue
          • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
          • External display (HDMI) shows
          ...

          ASUS TP500LA BIOS request/repair/merge?
          by jbonavita
          Hi, my laptop wont boot at all
          With original bios no POST, only LED lights
          With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
          Some issues
          A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
          B- If updated from 500LN version 203 to 300, the battery stops being recognized

          Things I tried

          1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

          [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
          by zenius
          Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

          Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

          HP Pavilion Gaming Laptop 15-ec2523nd - Dimm2 slot disabled after corrupt bios repair? Advice requested.
          by Bloodhoundje
          Hi everyone,

          I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.

          I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.

          After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.

          I have desoldered the bios chip (GigaDevice...
