My laptop power cord's ground prong (the third prong) broke off, and it stopped working in most wall plugs. I ordered a new one and when it came, it didn't have a third prong, but it works fine. Why is that? And more importantly, is there some future situation where I'm going to regret not replacing the old one with a new, three-prong plug? [more inside]

Can I damage my laptop by using a power adapter that has a slightly higher wattage than the original adapter? The original adapter was 65W, and the aftermarket one is 70W. The voltage is switchable. My original adapter had a voltage of 18.5V, this one says that if I need 18.5V, I should choose 18V. Any chance of damaging the computer by using this one? [more inside]
