Hardware Device Problems

DCU 220 does not recognize a newly installed device.
The device may not be correctly configured in the BIOS Setup program. Run the BIOS

Setup program to identify the new type.
Make sure if any device driver needs to be installed. (Refer to the documentation that

came with the device.)
Make sure if the device needs any jumper or switch settings. (Refer to the

documentation that came with the device.)
Check the cables or power cords for correct connections.

For an external device that has its own power switch, make sure that the power is

turned on.

Keyboard and Touchpad Problems

The keyboard does not respond.
Try connecting an external keyboard. If it works, contact an authorized dealer, as the

internal keyboard cable might be loose.
Water or liquid is spilled into the keyboard
Immediately turn off DCU 220 and unplug the AC adapter. Then turn the keyboard

upside down to drain the liquid out of the keyboard. Make sure to clean up any part of
the spill you can get to. Though the keyboard of DCU 220 is spill-proof, liquid will
remain in the keyboard enclosure if you don't remove it. Wait for the keyboard to air
dry before using DCU 220 again.
The touchpad does not work, or the pointer is difficult to control with the touchpad.
Make sure that the touchpad is clean.


LAN Problems

I cannot access the network.
Make sure that the LAN cable is properly connected to the RJ-45 connector and the

network hub.
