    @anbu, Good day,

    It sound like you are trying to move the mouse from your external display to your laptop, please check that they are on the correct side of each other. 

    1. Open System Preferences from the Apple menu 
    2. Click on the Display icon
    3. Choose the ‘Arrangement’ tab
    4. Click and hold on the white bar at the top of the current primary display, this white bar signifies the menu bar
    5. Drag the white bar across to the other monitor you want to set as the new primary display for your Mac
    6. Notice the red border that forms around the new primary screen as you drag the white bar into the arrangement, this helps you determine which screen to use as the primary screen
    7. After you release the white bar onto the other blue screen representation, the screens of both displays will flicker on and off briefly and the video output will adjust to accomodate the new settings
    8. When satisfied with the new primary display setting, close out of System Preferences to keep the preferences set
