system date and system time.

Establishing a Supervisor Password Using Computer Setup

If the system is equipped with an embedded security device, refer to the HP ProtectTools Security
Manager Guide at http://www.hp.com. Establishing a Supervisor password through Computer Setup

the ROM, and make changes to certain plug and play settings under Windows.

●
Asset tag (10 characters), a property identification number assigned by the company to the

● Reset to Factory Settings (some models) (Do not reset/Reset) - Resetting to factory defaults
will erase all security keys. Changing this setting requires turning the computer off and then
back on.
CAUTION: The embedded security device is a critical component of many security schemes.
Erasing the security keys will prevent access to data protected by the Embedded Security
Device. Choosing Reset to Factory Settings may result in significant data loss.
●
Reset authentication credentials (some models) (Do not reset/Reset) - Selecting Reset disables
the power-on authentication support and clears the authentication information from the
Embedded Security Device. Changing this setting requires turning the computer off and then
back on
PAVP (Some models) (disabled/min/max) - PAVP enables the Protected Audio Video Path in the
Chipset. This may allow viewing of some protected high definition content that would otherwise be
prohibited from playback. Selecting Max will assign 96 Megabytes of system memory exclusively to
PAVP.
