Diagnosis Netbook Murder

So, you think that the AC Adapter for your netbook is broken, but aren't sure. You really don't want to spend money to have someone "look" at it, but you're at a loss as to what to do. Guess what, there's a relatively simple solution. Stores surprisingly want you to buy their stuff. Take your netbook to the store you purchased it from or another dealer that sells netbooks and tell them the issue. Then ask if they might have one on display that you could use to test the adapter with your netbook. If it works, wallah, you're a computer genius and you seriously should get paid for this stuff. Well, let's not go that far, but hey you solved the mystery and you can now purchase an AC Adapter.
