Attached is a BIOS backup from a third laptop that does not have a password-protected BIOS.
It also has a 5 MB BIOS backup.
I don't know why the size is so small, but it's probably fine.

For the password-protected laptop, I tried downloading the file/BIOS from this thread called HP ProBook 6470b (6050A2466401-MB-A03.bin.
I renamed it on the flash drive E:\HEWLETT-PACKARD\BIOS\New to 68ICE.BIN and deleted the original 5 MB file/BIOS.
1) I turned off the laptop.
2) I pressed and held Win + B + POWER
3) the laptop turned on and started loading from the flash drive
4) after an automatic restart, an ERROR 500 message

Can you help me?
I don't know what to try anymore...
