Using battery power
WARNING!To reduce potential safety issues, use only the battery provided with the computer, a
replacement battery provided by HP, or a compatible battery purchased from HP.
The computer runs on battery power whenever it is not plugged into external AC power. Computer battery
life varies, depending on power management settings, running programs, display brightness, external
devices connected to the computer, and other factors. Keeping the battery in the computer whenever the
computer is plugged into AC power charges the battery and also protects your work in case of a power
outage. If the computer contains a charged battery and is running on external AC power, the computer
automatically switches to battery power if the AC adapter is disconnected on the computer or an AC power
loss occurs.
NOTE:When you disconnect AC power, the display brightness is automatically decreased to save battery
life. Select computer products can switch between graphic modes to increase battery life.

							7Security
Protecting the computer
Standard security features provided by the Windows operating system and the non-Windows Computer
Setup utility (BIOS) can protect your personal settings and data from a variety of risks.
NOTE:Security solutions are designed to act as deterrents. These deterrents may not prevent a product
from being mishandled or stolen.
NOTE:Before you send your computer for service, back up and delete confidential files, and remove all
password settings.
NOTE:Some features listed in this chapter may not be available on your computer.
NOTE:Your computer supports Computrace, which is an online security-based tracking and recovery
service available in select regions. If the computer is stolen, Computrace can track the computer if the
unauthorized user accesses the Internet. You must purchase the software and subscribe to the service in
order to use Computrace. For information about ordering the Computrace software, go to

							Using passwords
A password is a group of characters that you choose to secure your computer information. Several types of
passwords can be set, depending on how you want to control access to your information. Passwords can be
set in Windows or in Computer Setup, which is preinstalled on the computer.
●
BIOS administrator and DriveLock passwords are set in Computer Setup and are managed by the system
BIOS.
●
Windows passwords are set only in the Windows operating system.
●
If you forget both the DriveLock user password and the DriveLock master password set in Computer
Setup, the hard drive that is protected by the passwords is permanently locked and can no longer be
used.
You can use the same password for a Computer Setup feature and for a Windows security feature. You can
also use the same password for more than one Computer Setup feature.
Use the following tips for creating and saving passwords:
●
When creating passwords, follow requirements set by the program.
●
Do not use the same password for multiple applications or websites, and do not reuse your Windows
password for any other application or website.
●
Use the Password Manager feature of HP Client Security to store your user names and passwords for
your websites and applications. You can securely read them in the future if they cannot be remembered.
●
Do not store passwords in a file on the computer.
The following tables list commonly used Windows and BIOS administrator passwords and describe their
functions.
Setting passwords in Windows
Password Function
Administrator password* Protects access to a Windows administrator-level account.
