While you are typing, the on-screen pointer may seem to move or 
jump around “by itself” to random locations on the screen. The 
on-screen pointer may also seem to automatically select text, click 
buttons, and activate other user interface elements. For help with 
these problems, try one or more of the following:

❖

Try adjusting your typing technique to avoid accidental contact 
with the touch pad. You may be inadvertently brushing the 
touch pad with the heel of your hand as you type. Also, 
accidental light touches or taps on the touch pad may select an 
item or text on the screen, and potentially the item or text may 
be replaced by the next character you type. 

❖

Temporarily disable the touch pad, so that it does not respond 
to touch or button presses while you type. See 

.

❖

Disable the tapping feature. If you disable tapping only, you 
can still use the touch pad’s control buttons and move the 
pointer by sliding your finger on the touch pad.

❖

Adjust the sensitivity of the touch pad, so that it is less 
responsive to accidental light taps and lighter finger pressure.

touch pad setting options vary by computer model. The touch pad 
settings are accessible through the Mouse Properties option of the 
Windows Control Panel. For more information, please visit 

, and enter the phrase “Mouse pointer jumps 

around as you type” into the Search field.

The touch pad is enabled by default. To enable/disable the touch 
pad, do one of the following:

❖

Press the touch pad ON/OFF (

) button. 

(Available on certain models.)

❖

Press 

Fn + F9
