After years of bleeding edge innovative disasters, I had a common one.. Spilled tea on my laptop... Everything else is fine, but the touchpad is behaving erratically. Sometimes it gains a mind of its own, and the mouse pointer starts dancing all over the screen, and it keeps clicking left and right randomly.
Ashish suggested that it will be ok once it has dried off, and I'm currently hoping against hope that this happens, because its rather irritating to work like this, and I don't really want to lose a couple of days of productivity because of this.
