Cleaning Keyboard Contacts
Some keyboards have shown the symptom of not registering a
pressed key or keys. In many cases, this problem is caused by
dust, cigarette ashes, or dirt getting under the key mechanism.
This prevents the key mechanism from making proper contact with
the Printed Circuit Board located under the keyboard.
1. Turn power switch OFF.
2. Locate the troubled key.
3. Place a small flathead screwdriver beneath each side of the
key cap.
4. Gently pry off the key cap using the two screwdrivers.
5. Locate the two clips on the key mechanism that connects the
key mechanism with the keyboard.

6. Using two screwdrivers, gently press the clips on the key
mechanism towards its center with a lifting motion. The
^ mechanism should easily come out of its mounting hole.
