If you’re considering changing your BIOS version, it’s important to know that, according to the official release notes, you can only revert to version F.18. There isn’t an option to go back to earlier BIOS versions beyond that.
My advice is to hold off on any BIOS updates or downgrades until HP releases a new update that may fix issues you’re experiencing. Updating or downgrading your BIOS can be risky, and since you can’t go back to an earlier version than F.18, there’s a chance it might not improve your situation.
Looking at the update notes starting from version F.18, each new release has mainly focused on improving security features. For example, the latest update includes the 2024.2 security enhancements, which boost the security of the UEFI code. It’s important to note that once you install this BIOS update, you won’t be able to reinstall any previous versions.
HP strongly recommends updating to the latest BIOS version promptly because each update is designed to replace all previous releases and provide better security. So, if your system is running fine, it’s generally best to wait for a newer, more comprehensive update before making any changes.
