What is the procedure for factory resetting the HP EliteBook 9470m Notebook PC?

To perform a factory reset, press and hold the Power button for at least 5 seconds to turn off the computer if it is unresponsive. Then start Computer Setup from BIOS by pressing F10 during boot-up, navigate through options to find 'Restore Factory Default Settings', follow prompts to confirm the action, and wait for the process to complete before rebooting the system (Page 78).
