    BIOS update adapter

    After HP was so kind to brick BIOS in the Elitebook/ZBook G5 series with a bad BIOS update, we were only left with one option, and that is to program the EEPROM manually.

    If no SOIC adapter is available, this method can be used, without even having to remove the EEPROM. Just remember to disconnect the laptop battery.

    Read the old EEPROM, replace the upper 16 MB with the newest image from HP, and reprogram the EEPROM.

      Your soldering job is questionable at best. Please use flux in the future, and for fuck sakes use proper jumper wires, not the shit ones you got out of your arduino experiment box.

          Dell 9010 MT BIOS Update Always Fails
          by mikeybass
          Hi, I hope some one has some advice for me. I searched the forums but didn't see anything relevant. I acquired two identical Dell 9010 Mid Tower computers from a business office upgrade (they were going to throw them out). Both of them have the same motherboard (00F82W). One of them works flawlessly. The other one had a corrupted BIOS. I tried flashing numerous main BIOS and EC files from the internet, but none of them worked. I decided to copy the main BIOS and EC from the working 9010 computer and successfully flashed the corrupted BIOS. This got the computer able to boot again and run norm...

          Fixed: Lenovo P14s Gen 1 (type 20Y1, 20Y2) Laptop (ThinkPad) bricked by a withdrawn BIOS update (r1buj82w)
          by akwky
          Hi!
          Went dumpster-diving and found a bricked Lenovo P14S in trash, few weeks earlier. Symptoms - no screen, no POST, no beep, just keyboard LEDs flashing on powerup. Mute button+LED was responding though, and the display self-test was still working (via the key combo Ctrl+Fn+Power held for some seconds, see the Service manual).

          Incidentally, Windows 11 have recently started auto-flashing computer BIOS in our region. Even more suspiciously, Lenovo has released a BIOS update just few days before the PC was trashed. About a week later, the BIOS update image has been oficially marked...

          BIOS update wont complete - Dell Latitude 7420
          by Julian Bailey
          Hi all

          Anyone come across this issue where a BIOS flash will only part complete?

          It will update the system BIOS and Primary EC BIOS fine but fails to update the Intel TBT Retimer, Intel TBT Retimer 2 and ME Firmware.

          NVMe m.2 drive isnt detected in the BIOS, but you can get into the BIOS fine and it all works in there as intended.

          The drive works fine in another laptop.

          Link to a video I made of what its doing here:

          Any ideas on how to overcome this?

          Cheers...
