Troubleshooting

This section contains solutions for problems Toshiba had found when this document was written. If you have a problem that isn't covered here, refer to your computer's User's Guide for general troubleshooting procedures.

If your problem is with a PC Card or expansion card, contact the manufacturer of the card or Microsoft. Microsoft's Web site contains a great deal of information about hardware devices.

If your problem continues and it is with a Toshiba feature or utility, refer to your computer's User's Guide for information about contacting Toshiba.

Crystal audio and SoundBlaster Pro

For the Crystal sound drivers to work properly, the WSS address must be set to 534H and the SoundBlasterPro address must be 220H.

Refer to your Windows NT 4.0 online Help for information about changing settings for Multimedia devices.

Using APM with a PC Card network adapter

If your are using APM and a PC Card network adapter under Windows NT 4.0, install the network driver first and then the APM driver in that order. This ensures that the computer maintains the network connection in Suspend/Resume mode.

US Robotics Sportster 28.8 Modem

Some users have reported a problem with the US Robotics Sportster 28.8 modem under Windows NT 4.0 Workstation when using Hyperterminal.

After dialing a number, exiting and re-entering Hyperterminal, the program may not re-dial the previous number and may report that you are already connected.

To work around this problem, Try the following.

1. Remove the name.ht file for the session during which the problem occurred.
2. Add a new connection, re-enter the problem telephone number, and save the entry.
   Hyperterminal creates an icon for newname.ht.
3. Dial the newly created number.
4. Open the session that caused trouble and select Properties from the File menu.
5. Change the Port setting to the default or another selection.
6. Exit Hyperterminal.
7. Double-click the newly created newname.ht icon and redial the problem number.

If the connection still is not normal, try switching back and forth several times between the problem and new entries, as explained in steps 3 and 4.

If you continue to have this problem, check periodically on the Microsoft and US Robotics web sites for a fix or patch for Hyperterminal.

Uninstalling APM

You can remove APM, by double-clicking the Add/Remove Programs icon in Settings, Control Panel and following the instructions.
