need dump for hp ProBook 450 g8 password

[hoaca388]

Hi everyone, I am repairing an HP Probook 450G8 laptop with a Bios password, it boots into Windows normally, however after turning off the computer, the screen does not appear, the next day when I start it up it comes back up, then after turning off the computer it does not start up, it keeps repeating like that. Can anyone help me remove the Bios password and fix it?

Unlocked

thank you for your help, however after I finished recording, the machine could not boot, the fan did not spin, everything was silent. I looked carefully again and discovered that this laptop EC ROM and SPI ROM are separate, the file I uploaded before was EC ROM, now I will upload both EC and SPI files, hope you can help

Hello!
I wanted to post on the forum with a question about unlocking the BIOS, but during soldering, one of the EC ROM pins was torn off. The original EC ROM dump is permanently lost. I only have the original SPI ROM dump.

I replaced the original EC ROM GD25B256DYIG with a Winbond 25Q256JVEQ and flashed the dump from this thread. However, the laptop blinks 7 times and does not turn on.
I kindly ask for help in restoring the laptop’s functionality.

@Keg85 : Your version is T70, please find the correct version.

Maybe someone has a suitable version for EC (bid T70)? I've tried many files from this thread, so far without success.
