button for at least 8 to 10 seconds until the computer turns off. Press the
power button again to restart the computer.
CHECK THE KEYBOARD CABLE
• Shut down the computer (see page 22), reconnect the keyboard cable as
shown on the Start Here
setup diagram for your computer, and then restart the
computer.
• Ensure that the keyboard cable is firmly connected to the computer.
• 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.
TEST THE KEYBOARD — Connect a properly working keyboard to the
computer, and try using the keyboard. If the new keyboard works, the original
keyboard is faulty.
