    Dell Latitude 5280 BIOS unlock?

    Hello great people from the most respectable forums in the world.

    Bought this laptop in defective state with BIOS password active, and after fixing some problems it had in the board wanted to ask help for removal of the password if somebody can help me ?

    I have read the BIOS chip W25Q128BV@WSON8 which is 16 MB in size, I hope this is the corect chip that I should read, and attached here that BIOS backup also a picture of what the laptop asks on screen.

    Thanks very much

      Thanks bro, it worked by original site just by exchanging the letter 'Z' on keyboard
      So the password was CpZ30ZW6Ltt2L085 but after trying also your suggestion and saw that it is not working then I did exchange the letter Z and it worked.

      I thought this Service tag can not be done via Calculation


      Thanks very much

        Must use Qwerty keyboard, US layout to enter password.

            According to hoaca388:
            Change 698333M2-6FF1 to 69833M2-BF97
            Must use Qwerty keyboard, US layout to enter password.

                    thanks in advance
                    If the BF97 suffix doesn't work, why you don't try with the 6FF1 suffix ?

                                  Try the 2 password one by one.
                                  First one: Q25y2rqmb9E91GGG
                                  Second one: FINr8768M4NJyJQ3

                                  Use external US Keyboard (QWERTY), be careful with Upper and Lowercase Letters and Hold Left Ctrl Key Then Press Enter Twice.

                                        If the BF97 suffix doesn't work, why you don't try with the 6FF1 suffix ?
                                        Working ! Thanks Friend

                                          I try plugging charger while pressing ctrl+esc, machine turns on, nothing and after 20 seconds it gives 3 amber 3 white blinks again.

                                          Dell Latitude 7420 BIOS Unlock Gone Wrong
                                          by Jeff'sTech
                                          Hello everyone.

                                          I have come here with a rather specific question. I was given a Dell Latitude 7420 laptop with a busted screen, and wanted to see if I could refurbish it into my daily driver. I wanted to experiment and see if a 2-in-1 display would work as the chassis of the laptop and 2-in-1 7420 looked identical. I threw in the display and my hypothesis was correct, however, I was greeted with a locked BIOS and since I didn't know the password, I figured I'd try to unlock it somehow. I bought one of those POGO pin probe things for my CH341A programmer so I could read and make...

                                          Dell Latitude 5400 Chromebook UEFI bios

                                          Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.

                                          so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
                                          in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, 😅😅😅...

                                          Hi

                                          i have dell latitude E7270 with following symptoms:
                                          - takes long time to restart.
                                          - sometimes powers on and then off
                                          - sometimes while working it just dies,

                                          From googling online bios clean could possible resolve this?

                                          i was able to save bios and was going to try bios clean myself but get an below error when i drop it in ME analyzer.(unsure whether this sometimes occurs or could be due to bad/corrupt bios)

                                          As ME analyzer gave me an error i just decided to write bios with a cleaned bios from E7270 bios post.
                                          I reinstall...
