Chapter 4 Troubleshooting
If the pen does not turn on when you remove the cap, if it does not charge or is not detected by the PC
when you dock, use the following checks to determine the cause of the problem.
Checking the Pen
To check that the pen is functioning correctly, do the following:
Check that the pen is on: both the power and memory LEDs should be lit.
1.
Put on the pen cap. The LEDs should go out.
2.
Remove the cap from the pen and the LEDs should flash briefly then show the appropriate color for
3.
the battery charge level (see "Power LED" on page 7) and memory usage (see "Memory LED" on
page 8). The pen will also vibrate briefly to indicate that it is ready for writing.
If the LEDs do not light as described above, ensure that the pen battery is charged by placing
•
the pen in its cradle for 20 minutes.
If the LEDs do not light after 20 minutes, ensure that the cradle is correctly connected (see
•
"Checking the Cradle" on page 36) and try charging the pen from another PC with a cradle
that is known to function correctly.
If after checking the pen, cradle and software the pen is still not functioning, try performing a
•
pen reset (see "Resetting the Digital Pen" on page 37).
Note:
If the pen cap is left off, and the pen has been configured to automatically power-off (see
"Configuring the Pen Power-Off" on page 19), the pen will switch itself off automatically
after the specified time. To power on the pen, put the cap on the pen and remove it again.
Checking the Cradle
When the cradle is correctly connected and powered, the pen LEDs will remain on when the pen is
placed in the cradle. If the LEDs go out when the pen is in its cradle, check that the cradle is firmly
connected to the PC's USB port. For more information, see "Connecting the Digital Pen" on page 13.
If the cradle is connected to the PC using a USB hub, then be sure to use a powered USB hub. Your pen
will not charge if connected to a non-powered USB hub.
Note:
If the pen battery is completely discharged, the LEDs will not light immediately even if the
cradle is correctly connected. Allow the pen to charge by placing the pen in the cradle for at
least 20 minutes.
Checking the Pen Download Software
If the Pen Download Software is correctly installed, there is a pen icon in the Windows taskbar. If this
icon is not present, you need to install or reinstall the software. You can also check that the Pen
Download Software is installed by clicking Control Panel > Add/Remove Programs.
When the pen is docked, the dot on the icon turns from red to green. If the pen icon does not turn
green, check the pen and the cradle are correctly connected and that the pen is charged.
Note:
If the pen is configured in silent download mode or in download later mode, it can appear
that nothing happens when you dock the pen.
