60 Appendix A Troubleshooting and Support
Ports and connectors
The C5 is in the docking station, but the system does not recognize any accessory
devices, such as the external disk drive or monitor
• The C5 may not be fully seated in the docking station. Remove the unit from the
docking station and then replace it.
Network
The wireless adapter keeps connecting even when I do not want it to
• The wireless adapter is enabled. You can use Motion Dashboard to disable the wireless
adapter. See “Enabling or disabling Wi-Fi” on page 43.
Audio
No sound is coming from the speakers
• The volume may be set too low or muted. You can use Motion Dashboard to increase
the volume or turn mute off.
• The integrated audio components may have been overwritten. If you install a third-
party audio device (such as a USB or Bluetooth device), the integrated audio may stop
working. If this happens, reinstall the SigmaTel and Knowles Acoustics audio drivers. If
you still have problems after reinstalling the drivers, contact Motion Technical Support.
System
I forgot my BIOS password and cannot access my computer
• You can enter several incorrect passwords before the BIOS temporarily locks the system.
You can try again by restarting the system. If you still cannot log on, contact Motion
Computing Technical Support at www.motioncomputing.com/support.
An application has stopped responding, but I can still move the pointer and use other
applications
• Use Task Manager to manually stop the application. (Press the Windows Security button
and tap Task Manager.) See Windows Help and Support for more information.
The computer seems to be operating more slowly than usual
• The hard disk drive may be full or nearly full. You can use Disk Cleanup to free up space
on the hard drive. For more information, open Windows Help and Support and search
for “disk cleanup”.
• The hard disk may need to be defragmented. You can use Disk Defragmenter to
consolidate files and folders on the hard drive. For more information, open Windows
Help and Support and search for “disk defragmenter”.
