Troubleshooting

Solving Problems

∙Insert the PC Card in a different slot.

∙Press the blue power button to suspend the OmniBook, then press it again to resume.

∙If the card requires an IRQ, check that there is one available. If necessary, set the IRQ to an unused value manually.

If you’re using Windows 95 or Windows 98, look in Device Manager under Properties, Interrupt Request (IRQ).

If you’re using Windows NT, click Start, Programs, Administrative Tools, Windows NT Diagnostics.

∙Check the HP Customer Care website (http://www.hp.com/cposupport/eschome.html) for information about installing certain PC Cards.

∙Reboot the OmniBook.

∙Zoomed Video is supported in the lower card slot only.

∙Windows NT does not support Zoomed Video.

∙Try the card in another computer.

∙Not all 3rd party PC cards have been tested with the OmniBook. Please check the OmniBook website (http://www.hp.com/omnibook) for a list of approved and tested PC Cards.

∙For a Xircom CE2 (IIps) LAN card, certain of these cards conflict with the game port device in Windows 2000. Contact Xircom to see if your card is one of these.

∙When using a PC card in a docking system, insert or remove the card while the system is turned on.

If an I/O card stops communicating properly

∙It may have been reset if the OmniBook suspended or turned off. Exit and restart the application.

∙Check settings in Control Panel (and in Windows NT Diagnostics).
