(13) A disc (CD or DVD) cannot be ejected.
Possible cause
Writing to a disc is in progress, or there is an error in the DVD drive.
NOTE
• Turn off the main power of the equipment before attempting to eject a disc by using the manual emergency
ejection hole. Do not insert an eject pin at an angle or apply too much force.
• No eject pin comes with the equipment. If an eject pin is not available, use another pin that fits the ejection hole.
(14) Keyboard input is not accepted.
Possible cause
An application has frozen, there is a problem with the cable connection, or the keyboard has failed.
1. Check whether writing to a disc is in progress (the drive access lamp is on or flashing). You cannot eject a disc
when writing to it.
2. Press the eject button at least five times.
3. Insert an eject pin into the manual emergency ejection hole. (See 2.6.1 Inserting an optical disc (CD or DVD).)
When the disc tray opens slightly, hold it and pull it out by hand.
Action
1. Keyboard input might not be accepted temporarily due to a frozen application.
If the equipment responds to Alt+Tab or Ctrl+Alt+Delete, try the following procedure:
i) Switch applications by pressing Alt+Tab and identify which application has frozen.
ii) After you identify the frozen application, use Task Manager to terminate the application. To start Task
Manager, press Ctrl+Alt+Delete. The Windows Security window will open. Click Task Manager.
iii) Restart the equipment.
2. Disconnect the keyboard interface cable and securely reconnect it to ensure a stable connection.
3. Connect the keyboard interface cable to another port.
4. Replace the keyboard with another keyboard to check whether the latter works.
5. Restart the equipment.
