Peeled a few labels off a Dell Latitude 131L (yes the one that doesn't want to install Vista, can't really blame it) and got left with a load of very sticky stuff and bits of label guff.
Don't have any spirits or thinners to hand to remove it and wouldn't really want to use them in case it eats through the laptop casing (would be very bad as it's not my laptop)
Whip out the old gaffer tape/duct tape and tear off a strip. Stick it down on the surface with the sticky stuff and rip it off, takes a bit of the sticky crap with it. Repeat as necessary. Yes you may worship me.
