To restore the original factory image from the restore partition on an HP commercial computer, which key should be pressed during power-up?

Pressing the F11 key during power-up is the correct method to initiate a recovery process on HP commercial computers. This key is specifically designated for accessing the HP Recovery Manager, allowing users to restore their system to its original factory image stored on the restore partition. This process is critical when dealing with software issues or when preparing the computer for new ownership, as it ensures that the original operating system and included software are fully restored.

While other keys serve various functions during the startup process, F11 is uniquely designated for recovery tasks, making it the appropriate choice in this context. For instance, pressing F10 typically accesses the BIOS settings rather than any recovery options, while holding the Ctrl key does not initiate recovery but is often used in other contexts, like safe mode. The Esc key, meanwhile, opens a startup menu that provides access to different boot options but does not directly lead to the recovery image. Thus, F11 stands out as the correct choice for restoring the system.
