General problems
The computer does not have an available USB port.
Check if there is an available
USB port on a USB hub. If not,
you will need to add a USB hub
or USB card.
A tablet status LED does not illuminate.
Verify that the tablet USB
cable is properly connected
to the tablet and to an
active USB port.
If you are connecting to a
USB hub device, make sure
the hub is connected to an
active USB port and that
the hub is active.
Try using another USB port
or USB cable.
The computer does not go to sleep.
When you are not using your
tool(s), such as a pen or mouse,
remove them from the tablet
surface or the tablet will continue
to send data, keeping the computer
awake. Other metallic or other
conducting objects can also cause
the tablet to send data. Keep the
tablet surface clear of all objects
when not in use.
The screen cursor is very erratic or jumps to unexpected locations.
On rare occasions the tablet may
receive interfering radio
frequencies from a computer
monitor or nearby AM radio station.
If you notice interference from a
monitor, move the tablet at least six
inches away from the monitor, or
change the monitor refresh rate or
monitor resolution.
