    Awesome! It works great on my laptop too.

            Hi. I have a problem with my Dell Latitude 5430.
            After disconnecting the battery, it stopped booting. It seems like the BIOS has reset to factory settings and fails to initialize — the keyboard lights up, the laptop restarts, and this cycle repeats endlessly.
            I’ve tried flashing several BIOS versions I found on forums, but it didn’t help.
            Please help me fix my backup.

                      I am having a hard time getting a good dump of the W25R128JV in this Latitude 4550. I have tried Neo Programmer and CH341 Programmer with a CH341a Black and the alligator clip, I am not using the 1.8v board. None of the dumps can be read by UEFITools.

                      System still boots. I have attached the attempts I have made at reading.

                      Thank you for your help with this, I truly appreciate your time.

                                      I have a Dell Latitude 5530 with a damaged RJ45 network connector. See the attached pictures.

                                      Have already searched on Farnell / Aliexpress / Ebay and had contact with several suppliers on Aliexpress and Ebay, but they cannot deliver this connector.
                                      Is there someone inside the EU, who has these connector(s) or perhaps defective motherboard(s) for these laptop models I have mentioned in the topic title.

                                      Pictures of these boards:

                                      BIOS password locked Dell Latitude 3440 (Service tag B4HNJX3)
                                      Have extracted the BIN and want to know how to rebuild a clean BIOS

                                      I have come across the 8F8C patcher but not sure if that would work in my case as the service tag ends in 0001.
                                      I tried it and although the log states it patched several mentions of 8F8C in the BIN, I haven't flashed it yet in case such a patch wouldn't work.

                                      Have also tried to extract a clean BIN file from Dell's .exe BIOS updates using 'Dell PFS Extractor', but not confidently; Ended up with a 25MB file instead of the same 32MB...
