                              [REQUEST] Fujitsu Lifebook E5513 – Full BIOS Dump Needed (.bin)
                              by TacticalFahrrad
                              Hi everyone,

                              I'm trying to recover a Fujitsu Lifebook E5513 (most likely 2023 model) that was bricked during a BIOS update. The update was interrupted (probably due to power loss), and now the laptop is stuck in a boot loop showing "PBB rollback" / "SBB rollback" messages.
                              BIOS access (F2) and Boot Menu (F12) are no longer possible – the system instantly reboots after the rollback messages.

                              I extracted the official BIOS update package from Fujitsu (contains FJNB2FD.CAP, ~18.7 MB) and tried tools like UEFIExtract, but it seems to only contain...

                              [REQUEST] 2MB BIOS Dump for Lenovo NM-E471 Rev 2.0 (Winbond 25Q16JWSIQ Chip)
                              by hyperwood
                              Hi everyone,

                              I’m looking for a 2 MB BIOS dump for a Lenovo IdeaPad 5 16ARH7H / Legion 5 with mainboard NM-E471 Rev. 2.0.

                              The BIOS chip is a Winbond W25Q16FW (1.8V, 2MB) and it's completely unresponsive / bricked. I tried recovery via USB but no success. Now I want to reflash it externally using a CH341A programmer.

                              I already found 32MB dumps (e.g. from Vinafix and Badcaps), but they are too large for the chip – and the last 2MB in those files are just FF FF FF....

                              ✅ What I need:
                              • A working 2MB BIOS dump
                              • Matching NM-E471 Rev. 2.0, e.g. JY575
                              ...

                              I need a BIOS dump for the Samsung S49CG934SU monitor
                              by Habble7
                              The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

                              Suspected Cause:
                              I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

                              Troubleshooting Attempts:
                              ...

                              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...

                              by hotcrossedbuns999
                              My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.
                              1. I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
                              2. I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
                              3. I could only locate two chips that look like bios chips. Could someone verify this
