Serial, Parallel, And Usb Problems - HP Notebook PC Reference Manual

Troubleshooting and Maintenance
Troubleshooting Your Computer
If the left edge of printed output is missing
• Certain applications may not work properly with 600-dpi printers. If you're using
such a printer, try selecting a compatible printer driver for a 300-dpi printer. For
example, if you were using a 600-dpi HP LaserJet printer, you might try using the
HP LaserJet IIIsi driver (300-dpi).
If an infrared printer doesn't print
• Make sure the line between the two infrared ports is not blocked, and that the ports
face each other as squarely as possible. (The computer's infrared port is located on
the front of the computer.) The ports should be no more than 1 meter apart.
• Make sure the printer is on and has paper in it.
• Check for printer errors.
• Make sure Windows is running; otherwise infrared printing is not available.
• See "Infrared Problems" on page 101.

Serial, Parallel, and USB Problems

Serial devices must be connected to the serial port on the port replicator.
If a serial mouse doesn't work
• Make sure you followed the manufacturer's installation instructions completely and
have installed the mouse properly. If not, repeat the procedure.
• Make sure the port connection is secure.
• Press the power button to suspend and resume.
• Restart the computer: click Start, Turn Off Computer (or Shut Down), Restart.
• Check mouse settings in Control Panel: click Start, Control Panel, Printers and Other
Hardware, Mouse (Windows XP), or click Start, Settings, Control Panel, and then
double-click Mouse (Windows 2000).
• Use a mouse that connects to the USB or PS/2 port. If you have a PS/2 keyboard
connected, use a PS/2 Y adapter (HP accessory F1469A).
•
Check the port settings in Control Panel. Open the hardware Device Manager, and
then double-click Ports (COM & LPT).
