I was using my laptop this morning as normal and, for no reason I’m aware of, the orange light on the touchpad came on and the screen arrow disappeared leaving me with only partial control of the computer through using the tab key. I’ve discovered that the inbuilt “mouse” has been disabled and this can be put right by by quickly tapping on the on/off switch. However, hardly surprisingly, all that is doing is switching it off and when I switch on again the orange comes on as before. Any ideas what else I can try? It’s a reconditioned computer which I’ve had for a few years now, so maybe it’s just showing its age?
