Owner manual

If a CD isn’t automatically detected when inserted in a drive

• Use Device Manager to view the CD-ROM drive properties. Select the auto-

detect setting. WARNING: This setting prevents the OmniBook from

automatically suspending after a period of inactivity if the CD-ROM drive is

present.

If the hard drive turns off prematurely (not matching your setting for hard-

drive turn-off)

• There are two separate settings that affect hard-drive turn-off, and the shorter

one will prevail.

• Check and set these two values to be the same:

• HP User Tools, OmniBook Power Management, Idle Time Before Turn-Off,

Hard Disk; and

• Control Panel, Power, Disk Drives, When Powered by Batteries.

If a backup-tape drive does not work correctly

• Its bus speed might be too slow for the OmniBook. You can decrease the

OmniBook’s bus speed by pressing FN+MINUS. (To restore the normal speed,

press FN+PLUS.)

Communications Problems

If you have problems with serial communications

• If a modem doesn’t work properly, in Windows Help use the modem

troubleshooter.

• If you cannot make a serial connection at high speed (115K baud), try changing

the Power Management setting in the System Configuration Utility to “Moderate”

(from “Maximum”).

If you have problems with infrared communications

• Move the devices to within about 1/2 meter (1.5 feet).

• Check that only one application is using the infrared port.

• Check that both devices are using the same protocol, such as IrDA.

• Make sure you’re using the COM4 port. (For printing, use the LPT3 port instead.)

• Start Infrared Monitor before you connect. In Control Panel, double-click

Infrared.

• For an MS-DOS program using an infrared connection, run the program in an

MS-DOS Prompt window instead of in MS-DOS mode.

• Try restarting Windows.

If an application can’t access a serial port

• Check that the COM name you’re using is actually assigned to the port you’re

using.
