Updating the BIOS
Download and install updates to the computer Basic Input Output System (BIOS). This process is also known as 'flashing the BIOS'. Updating the BIOS is recommended as standard maintenance of the computer. It can also help to improve computer performance, provide support for hardware components or Windows upgrades, or install specific BIOS updates.
Only install BIOS updates from HP. Installing the BIOS incorrectly can prevent the computer from starting or being recovered. If your computer is managed by an IT service, contact them for the correct update process.
For business computers such as ProBook, EliteBook, and ZBook models, your company IT department or local IT service might manage BIOS settings. Confirm that the updated BIOS version is compatible with your company's deployment environment.
