dell e1505 cursor problem help

Hello, my sister's e1505 has cursor problem, sometimes when she typing an email or report in word the cursor will jump randomly and mess up the typing.

She isnt accidently tapping the touchpad, any idea what would cause such behavior?

I really appreciate the help, thanks!

 

Sometimes you can accidentally graze the touchpad with your wrists or the meaty part of your hand where the thumb connects while you are typing. I know you said she wasn't 'tapping' the pad, but they are really quite sensitive to any skin contact whatsoever.

Cover the pad with something like or at least shaped like a post-it note (but dont get any of the sticky crap on the pad!) and have her type as normal. If the cursor stops hopping around, then she's just inadvertenly touching the trackpad.

That can be remedied by changing the way she types or having a piece of index card the right size she can lay on it. On some laptops (I don't believe the 1505 is one of them tho) there is a dedicated key that turns the pad on and off.

 

Also, if you use an external mouse, set the touchpad to be deactivated when an USB pointing device is connected.
