Solving Infrared Problems
Possible Cause
The appropriate software is
not running on both
computers.
The other computer does
not have an IrDA-compliant
infrared port. Your Compaq
computer uses the IrDA
communications protocol.
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.
There is an interrupt request
(IRQ) conflict.
There is a baud rate conflict. Select the same baud rate for both
Solution
Wait for the system to restore the
previously saved data to its state prior
to initiating a low power state.
Run ScanDisk and Disk Defragmenter.
Turn off and unplug the computer, remove
the hard drive, and reinsert the hard drive.
Boot from the original hard drive or a
specially prepared hard drive.
Remove, then reinsert the drive.
Try using the hard drive in another bay to
verify that the problem is with the drive.
Run ScanDisk on the drive.
Shut down the computer before inserting
removing a hard drive.
Completely turn off the computer. Turn the
computer back on, then run Computer
Setup by pressing F10 when the blinking
cursor light appears upper-right on the
screen.
Solution
Install the appropriate software on the
second device, start the second device,
and start the program on both computers.
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.
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.
Check for IRQ conflicts in the Device
Manager If two devices have the same
IRQ address, reassign one of the devices.
