No, gentle taps don't work. I am unwilling to smash it against the table or throw it on the floor, but have been tempted to a couple of times... <grin>. Of course, this computer did do a end over end tumble down about 15 marble subway steps about 8 months ago, but has worked well ever since, until now.
