          You have to buy a programmer, Ch341A for example.

                  Hello, help with bios for Dell Latitude 5421 with password, I attach images of the chip and motherboard, I read the bios with Ch341 black Edition and it did not read correctly and damaged the programming and I cannot go back. I programmed the chip with ezp2023+ with several binaries from the forum and the internet that claim to work for this model but the laptop turns on, but does not pass the test, and turns off. I need help to solve it. thank you

                    Type and post the service tag, then we can find the laptop configuration and look for a matching bios

                            S/T: J9LT0J3

                            I suspect I have a corrupted BIOS.
                            Laptop turns on. Keyboard light turns on. No POST. CPU gets hot which turns fans on. No display, not even backlight.
                            Built-in screen test runs.
                            Tried pulling BIOS battery and all the button pushing combinations online to no avail.

                            Attached is the BIOS dump.
                            I'd appreciate the help of the forum to get a repaired .bin to try.

                            Thank you thank you

                                Unfortunately it doesn't seem like a frozen BIOS issue.
                                Flashed it but still same behavior. I'll keep digging.
