Checklist for Solving Problems
If you encounter a minor problem with the computer or software applications, go
through the following checklist for possible solutions:

 Is the computer connected to an external power source, or does it have a fully
charged battery pack installed?

 Are all cables connected properly and securely?

 Did the diskette drive contain a nonbootable diskette when you turned on the
computer?

 Have you installed all the needed device drivers? For example, if you are using a
mouse, you may need to install a mouse device driver.

 Are printer drivers installed for each application?
Eliminating the typical problems described in this Troubleshooting section may save
you time and money. If the problem appears related to a software application, check
the documentation provided with the software. You may discover something you can
resolve easily by yourself.
If the condition persists, contact your Compaq authorized dealer or service provider.

The other computer does
not have an IrDA-compliant
infrared port. Your Compaq
computer uses the IrDA
communications protocol.Communication between infrared devices
must use the same communications
protocol. Check the manufacturer’s
instructions for connecting with infrared
devices or try connecting with a device you
know to be IrDA-compliant.
The pathway between the
infrared ports is obstructed,
one port is more than 30
degrees (plus or minus 15
degrees off the center line)
from the other, or the ports
are more than one meter
apart.Remove the obstruction, align the infrared
ports to within 30 degrees, and position
computers within 1.5 feet (about 0.5 meter)
of each other.
