        Bios is not open source. The laptop has been repaired so the original bios may be lost. Thank you for your enthusiasm, looking forward to further help to definitely rule out bios when repairing

        Markus1741 The machine from China has arrived, and I suspect the motherboard is a 7420 2-in-1 because the model numbers are the same, and the 7420 2-in-1 has a BIOS version of 1.37.0. Condition: The machine has a BIOS update error and won't power on.

                    Please, help me with the above laptop's BIOS unlock. the board number is LA-K371P.

                    I've tried other firmware dump on it but it displays red, green, white colors at random. I tried the dump that was made from the laptop, but same solid colors appeared.

                    please, help. attached was the dump that i got from the BIOS chip.

                      i have tried it sadly, it remains the same.

                      random off and on, fan runs at top speed. the caps lock light stays on.
                      after some time it will display red, white, blue, red, green, black colors.

                                  hello everyone, please i still need help with the BIOS problem.
                                  i tested random firmware i can find, the only best result thus far was the dell logo flashed once. There was nothing thereafter.
                                  Please, i'm literally in huge problem. the PC came to me for BIOS password, now i can't even bring the laptop to startup.

                                    post S/N, full name and model, motherboard model, product number,post the original contents of the bios chip..etc.

                                    write with the keyboard..

                                    you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

                                      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...

                                      I need help removing/unlocking the BIOS Service Tag password on my Dell Latitude 5520 laptop.

                                      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...

                                      3 amber 3 white blinks. Dell website sais it's problem "bios recovery" and suggested solution "recovery image not found"
                                      (from here https://www.dell.com/support/manuals...e7a&lang=en-us)

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

                                      Since ssd is replaced and had clean install windows, i've...
