[QUOTE="Jonzjob, post: 1674987, member: 149248"] Well tyical university student. She starts back next week after 3 months off! and told me that the jumping cursor hasn't gone away. So I have had another look at the battery and I even removed it, still connected and whilst supporting the MBP powered it up with the battery underneath but not touching the unit. The cursor still bounced, but I noticed that it only bounced vertically now! If you move it across the screen it just goes up and down in the new place. So there was definitley no pressure from the battery. The battery also looks OK and I can't see any swelling at all. I tried the 'ignore trackpad when mouse connected' in Accessibility and the mouse was perfectly stable with the mouse on. So was the trackpad sometimes, but not all the time when the mouse was switched off. I then booted in Safe mode and nearly went boss eyed trying to keep up with it with the mouse disconnected. So, I am now wondering if it could be the tracpad itself? I thought that they would be an arm and a leg to buy, but they seem a reasonable price? Nearly forgot!! I also cleaned around the very edge of the pad with a cotton bud damp with Isopropyl Alcohol, just damp. [/QUOTE]
