Hardware troubleshooting

Problem

Cause and action

When you are using the
port replicator, resuming
normal operation from
hibernation or standby
mode takes a long time.

If the Ethernet port is enabled, but the port replicator is not connected to a
network, resuming operation can take a long time. The computer queries
the Ethernet until the timeout timer stops the query. If you want to access
the Ethernet, connect the network cable. If you are not using the network,
disable the Ethernet connector as follows:

For Windows 98:

1. Double-click the System icon in the Control Panel.
2. Click the Device Manager tab.
3. Double-click Network Adapter.
4. Double-click Intel EtherExpress PRO PCI Adapter.
5. Mark the check box for Disable in this hardware profile.

  6. Click OK.

7. Close all windows.
8. Restart the computer.

For Windows NT:

1. Double-click the System icon in the Control Panel.
2. Select Intel EtherExpress PRO Adapter, and click Startup....

  3. Select Disabled.
  4. Click OK.
  5. Click Close.

6. Close all windows.
7. Restart the computer by turning it off and on again.

Your computer does not
enter standby or
hibernation mode.

Check whether any option has been selected to disable your computer
from entering standby or hibernation mode.
