Sources of Information
* The printed Startup Guide introduces the notebook computer and shows you the basics. It also contains
troubleshooting information.
* The online Reference Guide shows how to set up the operating system, install and connect accessories,
and maintain and upgrade the computer (for Windows 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.
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 the internet
IP address. See the readme file mentioned below.
If you have trouble setting up or using a wireless LAN connection, see the information about wireless LAN
in c:\hp\Drivers\Wireless\Readme.txt.
Working with Graphic-Intensive Applications
You can press Fn+F5 to switch between built-in and external displays. However, you should avoid
switching while graphic-intensive applications are running, such as multimedia or OpenGL applications. In
some situations, switching displays can cause video corruption or application shutdown.
You should also avoid pressing the blue sleep button the computer while graphic-intensive applications are
running. In some situations, this could cause the application or computer to lock up.
Working with Audio
If you are recording audio on your computer, keep the following suggestions in mind:
* To get optimum results using the built-in microphone, use the following settings. In Windows Volume
Control, mute the microphone control for playback. Then click Options, Properties and select the
recording option. Click Options, Advanced Controls to show the advanced microphone button. On the
microphone volume control, click Advanced and turn on the option to boost the microphone output.
* The audio line-in control is displayed even though there is no audio-in port on the computer. An audio-in
port is available on a dock.
Waking from LAN in a Dock
If you want your computer to be turned on from a signal arriving at the LAN port while the computer is
docked, you must attach the LAN cable directly to the computer LAN port, not to the dock LAN port. The
dock LAN port is disabled whenever the computer is off.
