      Notebook Keyboard Key Has Come Off

      It is possible for the keycap on the internal keyboard to get stuck or come off in the course of using a notebook computer. To put the keycap back on the notebook:

      Dell has created an online tutorial on how to put the keycap back on the notebook.
      Click here to view the tutorial! - NOTE: English Only

      1. Determine how the keycap connects to the notebook system.

        • Underneath the keycap is a rubber plunger and a plastic scissor spring (see Figure 1 and Figure 2).

         

        Figure 1: Bottom of Keycap, Scissor, and Plunger on a Notebook Internal Keyboard


        Figure 2: Notebook Internal Keyboard with the Scissor in the Raised Position

        • One style of notebook keyboard also includes a scissor support bar (see Figure 3).


          Figure 3: Optional Support on Notebook Keyboard

      2. Carefully line up the keycap on top of the plastic scissor and press down (see Figure 4).

      3.  
        Figure 4: Lining up a Keycap and Pressing Down

        Note:  
          You might need to wiggle your finger back and forth for the keycap to snap down on the scissor spring. There are two "snaps," one at the top and one at the bottom of the key.  

      4. If there is a scissor support bar and it has come loose, clip the lower part of the bar on first under the bottom scissor rail, then snap the upper part over the top scissor rail before lining up the keycap to reattach it (Figure 5).

          That Do Not Have Wires  


        Troubleshooting Wireless Mouse Issues
        1. Reinsert the batteries or install fresh batteries, (look for a red light on the bottom of the mouse).




        2. Make sure the port where the red light comes out is clean..




        3. Make sure the mouse is within 10 feet (3 meters) of the computer.




        4. Make sure the surface you are using has enough of a pattern in it so that the mouse can see it, a mouse pad is best, (the mouse judges movement by reflections, a uniform surface is harder for the mouse to tell when it has moved).




        5. Reseat the receiver in the USB port.




        6. Restart the computer.




        7. Press the Connect button on the receiver and on the bottom of the mouse.




        8. Try the receiver in another USB port on the computer, (make sure to press the Connect button on the receiver and on the bottom of the mouse again).




        9. Try the receiver in another computer if available, (make sure to press the Connect button on the receiver and on the bottom of the mouse again).
