    Dell G15 5525 BIOS fix

    I have a Dell G15 5525 that charges, responds to the power button, and pulls ~12 W with the battery disconnected. Fans spin, but there’s no internal or external video, and the caps lock LED stays on. I’ve checked power rails — all look good, no shorts found.

    The laptop shows a blink code of 2 orange, 3 white. I suspect a corrupt BIOS or EC issue. I tried BIOS recovery via USB (battery disconnected, original adapter, etc.), but it didn’t work. I have the full 25Q256JWEQ SPI dump. I need help creating a hybrid BIOS image that updates the main BIOS while preserving the board-specific info (ME/NVRAM/DMI) for flashing.

    Thank you in advance

          unfortunately the laptop is still doing the same thing, powers on, with only caps lock light. Maybe the EC?

              Any possible why that you could extract the EC image from the Dell BIOS file for me?

                  [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,...

                  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...

                  Help with BIOS update on Dell G15 5515 after chip replacement
                  by capoplays
                  Hey everyone,

                  I recently bought a Dell G15 5515 with an AMD Ryzen 7 5800H and 3060 RTX. The BIOS chip on it was dead, and my hardware guy replaced the chip. After that, everything was working fine.

                  The BIOS is currently at version 1.22.1, and I wanted to update it. I downloaded the latest BIOS version from Dell Support using my ST: FQZMYJ3, but when I tried to run it, it says "unsupported system." I asked my tech guy what he did, and he said he took the chip from another board and flashed it onto mine.

                  When I check the BIOS using the F12 menu Flash...

                  Dell Pro 13 Plus PB13250 Bios Unlock
                  by Akhlz001
                  Hi,

                  Could someone help trying to unlock this BIOS, seems that Dell have changed the layout of new Dell Pro 8FC8 bioses from checking HXD - 4000 bits do not need changing, only 2000. However after FF the section starting from '01000' upto 2000 bits and then soldering the chip back it seems that the microchip on the motherboard is recovering the bios back to original settings after first boot. Has anyone found a way to crack this extra layer of security Dell have implemented? Seems both HP and Dell have upped bios security to match Lenovo by implementing extra measures on a separate...

                  Dell Latitude 5431 issues with dumping bios
                  by Sathsul
                  So, i kinda spend significant ammount of the last couple of days trying to flash a new bios, and or unlocking the current bios password with little to no results.
                  The whole thing started with it being the 8fc8 bios, i found the tools to unlock that but i needed a bios dump. So i pursued that, im at a point where i dessoudered the chip, and succesfully soudered it to the ch341, dumped whatever was on it.
                  However, the tools supposed to unlock the 8fc8 say that there is no 8fc8 hex inside. And when i followed diffrent tutorials to just flash a new bios onto the chip i got stuck on the...
