Ok, I need to replace my AC Power Adapter, as mine has quit working, I went to Best Buy and bought a universal adapter but it cost me over a hundred bucks, it is still in the box, I then looked at Dell online, and they have the adapters at half the cost, I looked at the reviews and they are not good, so what do I do now? The one I bought at Best Buy was 90W, the that Dell offers is 65W. I will say that the reviews for (Rocketfish Travel Laptop AC Power Adapter) are not good either. Any ideas out of you technical people out there? Thanks for your help.
