Hi yes you can adjust.
Click the Start Orb then in the search programs and files type Mouse
Click Mouse above that was found then when the mouse Properties box opens click on the last tab saying Device Settings
Click to highlight the device and then click on Settings.
This will open up the touch pad settings.
This setting controls actual touch pad sensitivity. If the user has a light touch just move the slider to the left, having a heavy touch would require a move to the right. Light touch will increase the sensitivity; heavy touch will decrease the sensitivity.
The next setting will be the Palm Check. This option sets the touch pad for heavy typing or light typing. This control will help keep the cursor from jumping around while typing.
The palm check setting helps keep accidental contact to the touch pad from interfering with the typing. The palm check minimizes unwanted pointer or cursor movement. Increase settings to help prevent the problems, decrease if the problem does not interfere with the typing procedures.
Hope this helps
