A few days ago my N56VZ‘s touchpad went berserk. Scrolling was laggy and gestures either wouldn’t register at all or would register late. Sure I was using a bluetooth mouse so it wasn’t that big a problem – but what was I going to do when I had to take it with me to University?
A simple restart wouldn’t fix it. I uninstalled and reinstalled the drivers. I prayed and made a sacrifice to the sun god Ra. All to no avail. However…
Unplug your notebook – and crash it. Hold the power button down to force it to shut down, wait a couple of seconds, then boot it up again. The laptop will restore the old settings (those that worked) well and all will be good. It’s really weird and I don’t know why this doesn’t happen after an ordinary restart but there you go!
