    Attached Bios .....
    Sorry for the confusion are you asking me to attach a file, or have you attached one (if you attached one, I don't see it)

    I'm not able to dump the BIOS because Windows does not load, there is a software glitch and it doesn't boot to desktop, and the boot order doesn't allow for USB (so I can't run any dump utilities).

      you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow
      Due to a lack of donations, server free space at a critical level, and possible closure of Bios Requests all donations are welcome, click:

        I don't have a way to reprogram the eeprom. I didn't see everyone else posting their dump, my assumption was that someone could inject the serial number and UUID into a known working good SMC.

        I didn't want to have to rip this apart to change the mobo if I didn't have to.

          Hello, help me. I need to unlock the BIOS on my laptop. HP Spectre x360 Convertible 14-ea0520na (2Z6W0EA)

          I have access to Windows. Is it possible to unlock it through Windows? Do I need to unsolder the chip?

                      I post a schematic at your demand in schematic forum
                      No display not mean that's a bios issue !
                      you can post all the voltages you got at this forum and ask for help

                            Thread merged..next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread

                            Read the bios password guide ,use HP Unlocker/RCUnlocker to unlock it yourself -> https://www.badcaps.net/forum/troubl...rces-and-tools
