TOPIC



    When I connect an external mouse to my PowerBook 540c the mouse tracks very slowly. When I open the Mouse control panel is shows it is set to Fast. Sometimes when I select Fast in the Mouse control panel and it will track fast. I usually plug my external mouse in when I'm tired of using the built in Trackpad. Why does this happen?

DISCUSSION


    It is very important that you do not plug the mouse into the ADB port when the computer is "powered on". This may damage the ADB port or mouse. However, it is safe to plug in the ADB device when the Macintosh PowerBook 540c is in the sleep mode.

    Plugging in a mouse device on any Macintosh computer while the unit is powered on can result in slow mouse (cursor) movement and possible damage to the ADB port. In addition, the Macintosh PowerBook 500 series computers have two control panels influencing the speed of movement of the cursor: the Trackpad and Mouse. Their settings are related to each other. When you make a change in the Trackpad control panel, the Mouse control Panel also changes.

    Check to make sure the Trackpad and Mouse control panels are set to the same speed. Open the Mouse control panel and click on the speed you want, even if the speed is already selected. By clicking on the speed you will be sure to save that setting. Do the same for the Trackpad control panel.
