Surge protector (Ok, I have them for all of my electronic stuff).
Clean power? I think they mean a regulated voltage power supply. I didn't really give much thought to that and I didn't even check until you mention it. When I check them, I couldn't find out whether they are regulated or not. But I don't think you really need it. Laptop now days is more of a buy with the best performance per dollar and hope for it to not die before warranty and throw away and replace after warranty expire item.
Also may I ask how much you pay for your laptop and what is the exact model of the laptop? Harvey Norman has a reputation for their "upmarket" price"
