Updating the BIOS

Updated versions of the BIOS may be available on the HP Web site.

NOTE:

You can also determine the BIOS version by turning on or restarting the computer, pressing

the

esc

key while the “Press the ESC key for Startup Menu” message is displayed at the bottom of the

screen, and then pressing the

key. Follow the on-screen instructions to exit this screen.
