pop-up window opens.
7. Select Master HDP.
8. Type the current master HDP in the Enter Current Password field. then leave
the Enter New Password field blank, and press Enter twice.

To reduce power consumption, the computer has three power management modes:
screen blank, sleep (standby), and hibernation.

addition to what occurs in screen blank mode:
v The LCD is powered off.

operation with the keyboard, the hard disk, the parallel connector, or the
diskette drive within that time.
