Sources of Information

* The printed Startup Guide introduces the notebook computer and shows you the basics. It also contains

troubleshooting information.

and maintain and upgrade the computer (for Windows 98 or 2000, click Start, Programs, HP Library, or
for Windows XP, click Start, Help and Support, HP Library).

* The Microsoft Windows manual, shipped with your computer, contains information about using the

standard features of your Windows operating system.

Precautions

This section describes certain situations that could cause serious loss of data.

Do not remove a data storage PC Card while it is actively reading or writing. This could cause its data to
become corrupted.

Certain applications, such as Intuit's Quicken, keep their working files open, and they update the files as you
make changes. For such applications, you should open only files that reside on the hard drive, not on a
removable disk. An open file on a removable disk (such as a floppy disk or PC Card) is susceptible to
corruption in certain situations.

Before suspending, docking, or undocking your computer, always save your data and close any applications
you have open, especially applications that are not power aware, audio and video applications, and
applications using PC Cards and I/O devices such as a CD-ROM drive.

Changing Display Settings

To change display settings such as resolution (screen area) or extended desktop setup, you should use the
advanced Intel settings instead of the normal Windows settings. Open Display properties in Control Panel,
on the Settings tab click Advanced, Intel Graphics Technology, Graphics Properties, then change the
settings you want. Or you can click the Intel Graphics Technology icon in the taskbar.

Setting the Display after Docking (Windows 2000 or XP)

For Windows 2000 or XP, the first time you dock the computer in an expansion base, the display may
change to 640 × 480 resolution and look small on your screen. If this happens, change the screen area to
1024 × 768 as described in the previous topic.

Fixing Display Settings when Docking

When you dock or undock the computer to an expansion base, Windows automatically recognizes the new
devices connected to the system. However, the display settings may not change automatically to your
docked or undocked configuration. You may notice this if you have an external monitor with different
resolution than the built-in display. To switch to your docked or undocked display settings, press the blue
sleep button to suspend, then again to resume. Or shut down and restart the computer.

Using Wireless LAN

Here are some suggestions about setting the wireless LAN configuration:

* When you connect to a wireless network via an access point, your computer should be able to use

network resources. If, when you log on, your computer cannot connect to network resources, your
computer may not have been assigned an IP address. For Windows 98, to check your IP address, click
Start, Programs, MS-DOS Prompt and type winipcfg. For Windows 2000, to check your IP address, click
Start, Programs, Accessories, Command Prompt and type ipconfig. If the subnet mask for your wireless
connection is 255.255.000.000, the network server did not assign an IP address to your computer, and
you may have to release and renew your network IP address--see the readme file mentioned below. If this
does not fix the problem, the access point may need to be rebooted.

* If you want to change the SSID to a different value to connect to a different access point, or if you want

to change from Infrastructure mode to AdHoc mode, you may first have to release and renew your
network IP address--see the readme file mentioned below.
