Yes.

after restoring my original bios ( your unlocked bios didn't work ), the laptop won't turn on. power light blinks 6 times and caps lock light keeps blinking. pressing the power on button doesn't seem to do anything.

Hello, I am attaching two BIOS dumps from two HP EliteBook 840 G5 laptops - I was unable to reset the BIOS password using these tools:
https://www.badcaps.net/forum/troubl...os-unlock-tool
https://www.badcaps.net/forum/troubl...349-rcunlocker
https://gist.github.com/schorschii/7...7b65ff22c27337

RC unlocker fails, while the two others generate a file, but upon flashing it, the laptops are still locked.

@hoaca388 knows what he`s doing, there should be nothing wrong. Program both files again, and verify what is written to the chips. Check around them and make sure you havn`t dislodged any resistors

Hello everyone,

Please I need help resetting my HP EliteBook 840 G5 BIOS administrator and post power-on passwords. All I did was restart my laptop and the same password that I always enter during boot suddenly don't work again. It's strange and I'm confused.

I think you are confusing the Windows password with the Bios password, they are not the same. Look for a solution to recover or remove your Windows password, but check that you don't have caps on or that your keyboard maybe sending the wrong letters. Try plugging in a USB keyboard and try it with that.

I have no idea how you came to this conclusion. I didn't even say I was running a Windows OS. I'm using Linux Mint.

I have seen the video, and it doesn't seem like something I may be able to do for now. Don't have access to the right tools. However, the post-power-on BIOS password that didn't work before has worked again. Though I'm not sure if it's going to work again after another reboot. In the BIOS, I was able to change the administrator password but not the post-power-on password, as it was telling me "incorrect password" when I knew it was the right password.
