HP Desktop PCs - Updating the BIOS

This document includes the steps for finding, downloading, and installing updates to the BIOS (Basic Input Output System) for your HP or Compaq computer.
Updating the BIOS, also known as "flashing the BIOS," replaces the BIOS firmware. When completed successfully, a BIOS update can fix or enhance aspects of a computer's performance, or provide support for newly installed hardware. However, if an incorrect update is installed or if the update process is interrupted, the motherboard can be permanently damaged, leaving the computer unable to boot. It is recommended to update your BIOS only if one or more of the following conditions apply:
  • The update fixes a problem with your computer.
  • The update enhances your computer's performance in a desired way.
  • You are planning to change the operating system, processor, or other feature(s), and the current BIOS version will not support the new configuration.
  • An HP Support Agent, or an HP support document, recommends that you download and install a specific updated BIOS.
  caution:
Only install BIOS updates from HP. Do not install BIOS updates from the motherboard manufacturer's website. Doing so might prevent the computer from accepting an HP System Recovery.
For business computers, the BIOS settings may be managed at the IT level and may not be available to configure. To verify, please check with your company's IT department or your local IT service.
