CHECK THE KEYBOARD CABLE —
• Ensure that the keyboard cable is firmly connected to the computer.
• Shut down the computer (see page 13), reconnect the keyboard cable as shown on the setup

• Check the cable connector for bent or broken pins and for damaged or frayed cables. Straighten
bent pins.
• Remove keyboard extension cables and connect the keyboard directly to the computer.
