4.6 SYSTEM MANAGEMENT
This section describes functions having to do with security, power management, temperature, and
overall status. These functions are handled by hardware and firmware (BIOS) and generally
configured through the Setup utility.
4.6.1 SECURITY FUNCTIONS
These systems include various features that provide different levels of security. Note that this
subsection describes
only the hardware functionality (including that supported by Setup) and
does not describe security features that may be provided by the operating system and application
software.
4.6.1.1 Passwords
CAUTION: Both iPAQ 1.x and 2.0 systems support the use of Setup and Power-On
passwords and implement them in the same way. An iPAQ 2.0 system with enabled but
forgotten passwords may be restarted after clearing CMOS with the CMOS clear button
(section 4.5.1).
However , the iPAQ 1.0/1.2 does not include a CMOS clear button and
enabling and then forgetting both the Setup and Power-On passwords on an iPAQ 1.0/1.2
system will require invoking a special utility with a service password based on the unit
serial number and date.
The utility can be invoked only as a network application
through Compaq Customer Support .
Setup Password
The Setup utility may be configured to be always changeable or changeable only by entering a
password. The password is held on CMOS and if enabled and forgotten, will inhibit any changes
offered by the Setup utility. Refer to the previous Caution for dealing with forgotten passwords.
Power-On Password
These systems support the use of a power-on password, which may be enabled or disabled through
the Setup utility. The password is stored in configuration memory (CMOS). If enabled and then
forgotten on iPAQ 1.0/1.2 systems refer to the previous Caution statement. Forgotten Power-On
passwords for iPAQ 2.0 systems can be cleared using the procedure described below or the entire
CMOS be cleared (refer to section 4.5.1).
To clear only the Power-On password, use the following procedure:
1. Turn off the system and disconnect the AC power cord from the outlet and/or system unit.
2. Remove the cover (hood). Insure that all system board LEDs are off (not illuminated).
3. Locate the password header/jumper (labeled E49 on these systems) and remove the jumper
from pins 1 and 2 and place on (just) pin 2 (for safekeeping).
4. Replace the cover.
5. Re-connect the AC power cord to the AC outlet and/or system unit.
6. Turn on the system. The POST routine will clear and disable the password.
7. To re-enable the password feature, repeat steps 1-6, replacing the jumper on pins 1 and 2 of
header E49.
