Maybe, but you should test it first under a dos boot up + mouse.com, then
go into dos edit.
If you have a mouse cursor this way, its not a hardware problem.

                  1.Remove the LED Indicator Panel from just above the
keyboard by prying at the lower
                     corners with a flat-head screwdriver.
                  2.Move the keyboard out of the way by removing the two
screws just exposed by step 1,
                     pulling the release tab (located just above the LPT
printer port on the back of the laptop)
                     out, and lifiting the keyboard out starting at the end
near the LCD.

You should try reseatring the mouse ribbon cable.
