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.

SXGA+ Resolution on 15-Inch Displays

Some models with 15-inch displays have SXGA+ resolution (1400x1050) instead of XGA resolution
(1024x768).

If items on the screen seem too small for viewing comfortably, you can adjust certain display settings while
maintaining the SXGA+ resolution. In Control Panel, open Display and try the following suggested settings
on the Appearance tab.

Active Title Bar - Size 21 18
Active Title Bar - Font Size 12 8
Active Window Border - Size 2 1

Booting from a Floppy Disk or CD

Some new models have the hard disk drive as the first boot device to minimize startup time. If you want to
boot from a floppy disk or CD, reboot the computer and press ESC when you see the HP logo and prompt,
then select the floppy drive or CD-ROM/DVD drive as the temporary boot device.

Serial Mouse Problems

If you have problems with a serial mouse that you can't resolve using the suggestions in the HP notebook
manuals, you should consider using a PS/2 mouse instead. The PS/2 bus provides better support for
pointing devices than the serial bus does, especially when docking and undocking under power
management.

Using an Older Microsoft Mouse Model

The computer cannot use Standby mode with two of Microsoft's older mouse models (parts #28898 and
#07685). The suspend and resume activity causes the computer to lock up with these mice. If you are using
one of these mice, do the following to prevent this problem:

1. Open the BIOS Setup utility (reboot, then press F2).

2. In the Power menu, disable the setting for Resume on Serial Ring.

3. Save and exit the Setup utility.

Changing Smart CPU Mode

Smart CPU Mode is initially enabled in BIOS Setup. This setting allows the computer to conserve power
when it's running on battery power. This doesn't significantly affect performance in most situations.
However, if you notice slower performance for certain applications while running on battery power, try
disabling Smart CPU Mode in BIOS Setup (press F2 during boot).

Caution: Choosing a Modem Cable

To reduce the risk of fire, use only No. 26 AWG or larger telecommunications line cord to connect the
modem to the telephone wall jack.

Trying to Make a Modem Connection

Many countries impose a blackout period after a modem repeatedly fails to connect to a service provider.
The number of failed attempts and the period of time you must wait before trying again differ from country
to country. Check with your telephone company.

Using AOL 5.0 Software

AOL software version 5.0 automatically detects your modem and changes settings accordingly. However, if
your computer is a modem-only model (Ambit), the ESS generic modem settings may prevent the modem
from connecting at higher speeds. To change the settings, use the AOL software to open the Sign On screen,
then click Setup, Expert Setup. On the Devices tab, select the ESS modem and click Edit, then change the
modem to Hayes Compatible.

Using a CD-RW Module with a Docking System

If you use a CD-RW drive module in your notebook computer and in a docking system, you should
recalibrate the drive each time you move it, especially if you will be writing CDs. Use the CD-RW software
and a clean commercial CD for the calibration.

Windows Millennium

Signing Up on the Internet (Windows ME and 98)

If you use the Easy Internet Signup option for connecting to the Internet, but have trouble making selections
using the keyboard, try using the pointing stick or touch pad instead.

Windows 95/98

Energy Star Feature for Display Timeout

The Energy Star feature is implemented on the notebook computer. This feature automatically turns off the
display after a period of inactivity. This reduces power consumption and extends the life of the display. If
your computer is on and the display is dark, press any key or move the pointing device to turn the display
back on.
