responding to commands.
1. If possible, use the Windows Task Manager to isolate
and terminate the offending process.
2. Attempt the normal Windows shutdown procedure.
3. Restart the computer using the power button.
Workstation date and time
display is incorrect.
Real-time clock (RTC) battery
might need replacement.
1. Reset the date and time in the Control Panel.
2. Replace the RTC battery.
Workstation appears to
pause periodically.
Network driver is loaded
and no network connection
is established.
Establish a network connection, or use Computer Setup

to disable the network controller.
Cursor does not move using
the arrow keys on the
