Wireless
If your tablet PC is equipped with an integrated wireless device
such as 802.11 or Bluetooth wireless devices, you have a wireless
tablet PC.
■An 802.11 wireless tablet PC can connect to wireless
networks in corporate offices, your home, and public places.
Wireless networks include wireless local area networks
(WLANs) or “hotspots.” Hotspots are wireless access points
available in public places, such as airports, restaurants, coffee
shops, hotels, and universities.
■A Bluetooth wireless tablet PC can connect to other
Bluetooth wireless-enabled devices using a wireless personal
area network (PAN).

Wireless Local Area Network (Select
Models Only)
With the 802.11 wireless device, you can access a wireless local
area network (WLAN), which is composed of other computers
and accessories linked by a wireless router or a wireless access
point.
■A large scale WLAN, such as a corporate WLAN or public
WLAN hotspot, typically use wireless access points, that can
handle a large number of computers and accessories and can
separate critical network functions.
■A home or small office WLAN typically uses a wireless
router, which enables several wireless and wired computers to
share an Internet connection, a printer, and files without
additional pieces of hardware or software. Wireless access
point and wireless router are often used interchangeably.
Tablet PCs with 802.11 WLAN devices may support one or more
of three IEEE physical layer standards:
■802.11a
■802.11b
■802.11g
There are three popular implementations of WLAN adapters:
■802.11b only
■802.11b/g
■802.11a/b/g
802.11b, the first popular WLAN standard, supports data rates of
up to 11 Mbps and operates at a frequency of 2.4 GHz. 802.11g,
which came later, also operates at 2.4 GHz but supports data rates
of up to 54 Mbps. An 802.11g WLAN device is backward
compatible with 802.11b devices, so they can operate on the same
network. 802.11a supports data rates of up to 54 Mbps but
operates at a frequency of 5 GHz. 802.11a is not compatible with

Using Wireless Security Features
When you set up your own WLAN or access an existing WLAN,
always ensure that security features are protecting the WLAN. If
you do not enable security on your WLAN, an unauthorized
wireless user can access your tablet PC data and use your Internet
connection without your knowledge.
The most common security levels are Wi-Fi Protected Access
(WPA)-Personal and Wired Equivalent Privacy (WEP). In
addition to enabling WPA-Personal or WEP security encryption
on the router, you may want to use one or more of the following
security measures:
■Change the default network name (SSID) and password.
■Use a firewall.
■Set security on your Web browser.
■Enable MAC address filtering on the router.
For more information about WLAN security, refer to the HP Web
site at http://www.hp.com/go/wireless for details.
Installing Wireless Software (Optional)
Microsoft Windows XP supports WLAN configuration with the
Zero Client Configuration feature. HP provides a separate WLAN
configuration utility that must be installed if you plan to use

HP and Windows Password Guidelines
HP and Windows passwords are not interchangeable. You must
use an HP password at an HP password prompt and a Windows
password at a Windows password prompt. For example:
■If a power-on password is set, the power-on password (not
a Windows password) must be entered when the tablet PC
starts up or restores from Hibernation.
■If you set Windows to prompt for a password before
resuming from Standby, a Windows password (not a
power-on password) must be entered to resume from
Standby.
The same word or series of letters or numbers used for an HP
password can be used for another HP password or for a Windows
password, with these considerations:
■HP passwords can be any combination of up to 32 letters and
numbers and are not case sensitive.
■An HP password must be set and entered with the same type
of keys. For example, an HP password set with keyboard
number keys will not be recognized if it is entered with
embedded numeric keypad number keys. For information
about the embedded numeric keypad, refer to the “Keypads”
section in Chapter 3, “Pointing Devices and Keyboard.”
Windows Passwords
Administrator password Used to log on to the tablet as the
Windows administrator after Windows
has been configured to prompt for a
password at startup.
User password Used to log on to the tablet PC as
a user after Windows has been
configured to prompt for a password
at startup.

Using Power-On Passwords
A power-on password prevents unauthorized use of the tablet PC.
After it is set, a power-on password must be entered each time the
tablet PC is turned on or restarted. A power-on password:
■Does not display as it is set, entered, changed, or deleted.
■Must be set and entered with the same keys. For example, a
power-on password set with keyboard number keys will not
be recognized if you enter it with keypad number keys.
■Can include any combination of up to 32 letters and numbers

DriveLock involves a user password and a master password:
■A hard drive protected by DriveLock can be accessed with
either the user password or the master password.
■You can delete a user password or master password only by
removing DriveLock protection from the drive. DriveLock
protection can be removed from the drive only with the
master password.
■The owner of the user password should be the day-to-day
user of the protected hard drive. The owner of the master
password may be a system administrator or the day-to-day
user.
■A user password and a master password can be the same
word.
✎When you start the tablet PC from a hard drive protected with
DriveLock, and your power-on and DriveLock passwords are
identical, you will be prompted to enter only a power-on
password instead of both a power-on and a DriveLock password.

MultiBoot
A bootable medium or network interface card (NIC) contains files
that the tablet PC needs to start and operate properly. The
MultiBoot utility, disabled by default, enables you to identify the
devices and control the sequence in which the system attempts to
boot from those devices as it starts up your tablet PC.
Bootable devices include optical drive discs, such as CDs or
DVDs, bootable diskettes, or NICs.
✎Some devices, including USB devices and NICs, must be enabled
in Computer Setup before they can be included in the boot
sequence. For more information, refer to “Enabling Bootable
Devices in Computer Setup” in this chapter.
Understanding the Default Boot
Sequence
By default, when more than one bootable device is in the system,
the tablet PC chooses the startup device by searching enabled
devices and locations in a predetermined sequence.
On every boot, the system looks for bootable drive A devices
first. If it fails to find a bootable drive A device, it searches for
bootable drive C devices. Drive A devices include optical drives
and diskette drives. Drive C devices include optical drives and
primary hard drives.
The primary hard drive can only boot as drive C. The NIC does
not have a drive letter assigned to it.

✎An optical drive device (such as a CD-ROM drive) can boot either
as drive A or drive C, depending on the format of the CD. Most
bootable CDs boot as drive A. If you have a CD that boots as the
C drive, the system will boot the diskette drive before it boots the
CD.
By default, the tablet PC selects the startup device by searching
enabled devices and locations in a predetermined sequence.
You can change the sequence in which the tablet PC searches for
a startup device by enabling MultiBoot and entering a new startup
sequence, also called a boot order. Or, you can use MultiBoot
Express to set the tablet PC to prompt you for a startup location
each time the tablet PC is started or restarted.
The list below describes the default sequence in which drive
numbers are assigned. (The actual startup sequence varies by
configuration.)
■Default sequence for devices that boot as drive A:
a. Optical drive in an optional docking device MultiBay or in
an external MultiBay that contains a disc that boots as
drive A.
b. Diskette drive in an optional docking device or in an
external MultiBay.
■Default sequence for devices that boot as drive C:
a. An optical drive in an optional docking device MultiBay
or in an external MultiBay that contains a disc that boots
as drive C.
b. Hard drive in the tablet PC primary hard drive bay.
c. Hard drive in an optional docking device MultiBay or in
an external MultiBay.
✎Since no drive letter is associated with the NIC, changing the boot
order of a NIC does not affect drive letters of the other devices.

Understanding MultiBoot Results
Before changing the startup sequence, consider the following:
■When the tablet PC restarts after the boot order has been
changed, it considers only the first device of each drive type
when searching for a startup device (except for optical
devices).
For example, the tablet PC is connected to an optional
docking device containing an optical drive and a diskette
drive. In the default boot sequence, the optical drive comes
before the diskette drive. If the system fails to boot to the
optical drive (either because it does not contain a disc or
because the disc is not bootable) it does not try to boot to the
diskette drive. Instead, it tries to boot to he first hard drive
device present in the system. However, if there are two
optical devices, and the first optical device does not boot, the
system tries to boot to other optical devices in the system.
■Changing the boot sequence also changes the logical drive
designations. For example, if you start up from a CD-ROM
drive with a disc that boots as drive C, that CD-ROM drive
becomes drive C and the hard drive in the hard drive bay
becomes drive D.
■Starting up from a NIC does not affect logical drive
designations because no drive letter is associated with the
NIC.
■Drives in an optional docking device are treated like external
USB devices in the boot sequence and must be enabled in
Computer Setup.

Setting MultiBoot Preferences
There are two ways to set MultiBoot sequences:
■Set a new default boot sequence that the tablet PC uses each
time it starts up.
■Use variable boot sequences using MultiBoot Express. This
feature prompts you for a startup device each time the tablet
PC is started or restarted.
Setting a New Default Boot Sequence
