Q: which is better for the laptop- plugging it first into the wall then the laptop or the other way around
A: in to the wall first. Your laptop plug is a power converter. It converts ac to dc. so if you plug it into your laptop first there is chance that a spike of power can get to the laptop due to the fact for a split second the cable is at a low voltage state http://bitsandbytescomputers.sytes.net
