So I’m typing away on my MacBook Pro and suddenly the cursor starts jumping around the screen at random. Try as I might, I couldn’t control it with the trackpad. I have an external mouse for emergencies, so I plugged that in, and things seemed to calm down for a minute or two, but then the cursor started skipping around again. It even jumped around when I wasn’t touching the computer, which I found a little spooky. It would open up files all on its own, and when I was online it would open and close pages seemingly at will, as I looked on helplessly.
But it also had short times when it worked just fine. During one of those, I did some quick Googling and discovered that many, many computer users were having exactly the same problem, and not just on Macs — on PCs, too. Furthermore, none of these people, including technicians, had found a solution. One or two said they had the trackpad changed and that solved it, but that didn’t explain why I was having the same problem using a mouse. Obviously I didn’t even consider calling a techie to try to solve a problem that apparently had no solution.
I finally figured out that if I closed the lid to the laptop every time the cursor started getting the jitters and waited for a few seconds, when I opened it, it would work again, at least for a minute or two. Then sometimes it would work just fine for an hour or more. I was baffled.
This went on for days and days. Some days it was really bad, others not so bad. After a while I started to notice that it was matching my moods. When I felt edgy or restless, it jumped; when I was cool and collected, it behaved. What was up with that? I decided to troubleshoot the situation by trying my best to maintain my calm every day. Guess what? After a day or two, the jumping stopped. Now what am I supposed to make of that, if anything? Just a coincidence? OK, if you say so . . .
