I had an old HP elite book 2170p with bios password. One of YouTube video suggested to attempt updating the software with usb with HP bios update using win /b combination keys.
I tried it, nothing happened at all.
However, now when I press power button, the nout book does not turn on. the power button has no light, the screen is dark.

No, that’s a bad sign, often meaning that EC firmware is affected, too. That’s the controller that first stage powers up the machine when pressing the on- button.
But there are some machines which automatically load EC firmware from a defined area in the firmware, so it would be interesting to see how the corrupted bios did look.
