                                Dell Latitude 5530 BIOS Password Removal Attempted but I Broke the Laptop
                                by TopPop
                                Sorry for the long story. I have a Dell Latitude 5530 (i7) laptop (South Peak 15 MLK MB DDR4 203102-1 FK8VG$JA) with an admin BIOS password that I want to remove. Service Tag: HYKFPT3. Other than that the laptop worked OK.

                                I found a CH341A Black and went looking for the BIOS chip on the motherboard. After trying to read one chip that was a firmware chip but not the BIOS I think I found the BIOS chip labeled Winbond 25Q256JVEN. Altogether I think I found 4 different firmware chips in the laptop. The BIOS chip is a WSON8 6x8. I used the CH341A, NeoProgrammer, and a cheap pogo pin clip...

                                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,...

                                Hello Hello,

                                I have been browsing the site and gotten so much useful info from here, including extremely helpful boardviews and several other very useful types of information. I am very grateful to this community, as I have actually eeked out a living from buying salvage PC's & Macbooks and repairing them. So, thank you all in advance!


                                I have searched and found some useful information regarding my issue, but my case is a bit different than the info I'm finding. But if anyone here can give me any useful advice, it would be highly appreciated.

                                ...

                                Beginner Tutorial for using RCUnlocker to remove BIOS password?
                                by CanukTuk
                                Hello,
                                Kinda new to this, so hoping you will all give me a bit of a pass.
                                I came to this forum because need to remove the BIOS password on an HP EliteBook 850 G1.
                                I understand that I need to dumpt the BIOS to a dump file, process the dump file with RCUnlocker, then write the modified BIN file back to tthe BIOS chip.
                                Is there a beginner guide anywhere that describes the entire process for doing this?
                                I am reallly in the dark regarding which tool or tools are required to extract the BIOS dump file, then write the modified BIN back to the BIOS chip. The guides I have...
