Hmm ... The jumping cursor problem has been driving me mad. I have been putting it down to the combination of XenForo and Opera, but then it started happening today when I was composing a Hotmail email in the Chrome browser!
Ok, that seemed much more likely to be a hardware problem. I found a video on YouTube showing me how to get the keyboard out of my laptop so I decided to check that the connectors were pushed in correctly. I only went and slipped with a screwdriver and tore one tiny track in the keyboard ribbon cable!
So, now I have a keyboard with a jumping cursor, and the broken track seems to have affected only one key - the right arrow key. You don't realise how often you use the right arrow key until it stops working! It is incredibly annoying to have to drop back to a trackpad or mouse to move the cursor to the right ... It isn't so bad when I want to go to the end of what I am typing because I can use the End key for that, but moving one character or word at a time is now a faff. (And of course, the jumping cursor problem means that I keep having to move it back to where it was before it jumped!)
The tracks in the cable are so fine that I doubt that I could repair it without risking causing even more damage, and anyway, I have mislaid my soldering iron. I decided that the best thing to do was to buy a replacement keyboard, and that might also fix the cursor problem. I found a company on
eBay doing new D430 keyboards for £11.99 and was just about to order one, when my stepdaughter texted me asking if there was anything I fancied for Christmas so that's that one sorted for now!
Hopefully, the replacement keyboard will work perfectly.
