I have a HP zBook 15 that simply will not boot up. I keep on getting a message that says "A System BIOS Recovery has occurred. BIOS Recovery (500). " The system will run a System BIOS recovery but when it finishes, it goes right back to the error.

Have you tried flashing the BIOS? You would need to lookup a current BIOS then load it to a flash drive (there is a process to this) then during boot you can select to run it and flash the BIOS. I can provide a link if you need one.

I have not tried flashing the BIOS. I may not have to as the laptop has booted to the Windows log in screen. With that being said, what is the best option going forward. Would a system restore work or maybe updating the BIOS altogether?

I'd definitely update the BIOS, as it sounds like your current BIOS isn't very stable.

also verify the bios battery, it may be getting low
usually it is a CR2032 and should read 3 V

Hello all,  I was able to recover my laptop from the BIOS recovery (500). All I had to do was power off the machine and unplug the power. I then plugged the power back in and I held down the Windows key + B. I used process one in the link below:
