Should I install the BIOS update from this page?

Only if your laptop matches this exact model and configuration. The BIOS and System Firmware (X72) update here is specific to the HP ProBook 4 G1i 16 D78E9UA — never install a BIOS file meant for another model, and keep the laptop plugged in while it runs.
