New power cord not exactly what I expected, should I return it?

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]

Is my new (aftermarket) power adapter safe for my laptop?

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]

Help me charge my G4 Powerbook

The power connector to my G4 Powerbook is almost dead. It only charges in one very specific position, and I have to twist it around for a few seconds to find the sweetspot (rotating it in situ). Nothing is loose and nothing is visibly wrong. I tried squeezing the metal sleeve slightly to make it more elliptical in the hope this would create a tighter connection, but it made no difference.

uses for an unstable PC

Uses for an unstable PC? A department manager purchased a laptop, I won't say what brand, about a year and a half ago. It's had new RAM and two new hard drives. The power socket is coming off the motherboard. It wasn't cheap and is more powerful than some of the other laptops currently in use. However, you can't be sure it's going to start up on any given morning. We would normally add old laptops to a pool of portable equipment used by our 70+ lecturing staff, but they have enough problems with working equipment. There are several interesting hobbyist projects I could pursue (a digital picture frame springs to mind), but I'd like to at least attempt some sort of work-related deployment when he breaks down and buys a new laptop. Any ideas?
