HP elitebook 840 G3 pass

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

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?

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
