Are the power supply's that come with laptops also power surge protectors? Would they protect the laptop in the event of an electricity surge i.e. in a storm.
I notice that the power supply box states on it that it can become hot. It does indeed heat up. Can these power supply boxes overheat and can laptops become overheated and suffer damaged if they are left on for too long?
Also, although they are called 'laptops'; I read somewhere that they should ONLY be used on a level surface. Therefore wouldn't that mean that they should not be used on your lap? I also read somewhere that if someone used a laptop/notebook on their lap, that the laptop is more prone to over heating.
Please add replies.
