HP Book 800CT manual Resolving OmniBook Docking Problems, If network connections don’t work

Page 65

Make sure the mouse is plugged into the correct port. The mouse and keyboard ports look the same.

Turn the system off and on.

Reboot the system.

Undock the OmniBook, unplug and reconnect the ac adapter, then dock again.

If network connections don’t work

Make sure that the LAN cable is connected.

You normally lose connections when you turn off the system or undock. See if your network software has a reconnect feature.

Check your configuration files to make sure that the network drivers are properly installed.

If the green light on the docking system isn’t on, check power to the docking system, then try undocking and docking again.

Check that there is no address or interrupt conflict. Check these settings on the network board—or, if the board has configuration software, check the settings using that software— see the manual for the network board. Also check these settings in your network software.

If SCSI devices don’t work

Try rebooting and selecting a startup option that loads the SCSI drivers.

Check the device id for conflicts.

Make sure you turn on the SCSI devices before you reboot the system. They're configured at boot time.

Check your connections and SCSI termination.

Check your configuration files to make sure that the SCSI drivers are properly installed.

Try pushing the OmniBook into the docking system a bit harder.

If the green light on the docking system isn’t on, check power to the docking system, then try undocking and docking again.

Check that there is no address or interrupt conflict. The SCSI interface normally uses I/O address 3100F and interrupt 10.

If a network-enabled system locks up when rebooting

The following hints apply to Windows for Workgroups only:

Edit AUTOEXEC.BAT to disable Windows for Workgroups network support for all non- network startup options. Add the /N switch to the WIN command (win /n) for each of the non- network options.

Edit CONFIG.SYS and AUTOEXEC.BAT to load network drivers only for the “Docking system” startup option, and not for undocked startup options.

For other operating systems:

Check any available online tools—Device Wizard in Windows 95, for example—or check with your system administrator.

Resolving OmniBook Docking Problems

Below are several scenarios of problems that may occur when docking the OmniBook. Possible causes and troubleshooting tips are provided for each.

If your docking password isn’t accepted

Check whether Num Lock is off.

If you’ve forgotten your password, have your OmniBook at hand and call Hewlett-Packard support. See your OmniBook Support and Service booklet.
