I have an Dell Inspiron N5010. My wireless mouse and touch pad bar lock up on me. I cannot move my cursor/pointer only when I sign into my computer. Otherwise it's no hope. I tried everything I could possible do. Even the key to the right of F12 key. No luck. I can only tab or move the arrows L, R, U, D. That it. It will not allow me to change my setting in the mouse to enable it. Can someone help.
