Set video-out mode to NTSC (default), PAL,

NTSC-J, or PAL-M.*

Enable/disable all settings in the Intel
SpeedStep window. (When Disable is selected, the notebook runs in Battery Optimized mode.)
Specify how the notebook recognizes
multiple identical Port Replicators that are identically equipped. Select Disable to recognize the Port Replicators as a single Port Replicator; select Enable to recognize the Port Replicators individually, by serial number.
Enable/disable the reporting of the processor
serial number by the processor to the software. HDD Self Test Options Run a quick comprehensive self test on hard drives in the system that support the test features.
*Video modes vary even within regions. However, NTSC is common in North America; PAL, in Europe, Africa, and the Middle East; NTSC-J, in Japan; and PAL-M, in Brazil. Other South and Central American regions can use NTSC, PAL, or PAL-M.
2.2 Using Diagnostics for Windows
When you access Diagnostics for Windows, a scan of all system components is displayed on the screen before the diagnostics window opens. You can display more or less information from anywhere within Diagnostics for Windows by selecting Level on the menu bar. Diagnostics for Windows is designed to test HP components. If other components are tested, the results might be inconclusive.
