Hey Learning can you post a pic of your Uno?? I am curious if it has the other 'features' of a fake arduino such as the chip markings sanded down.
You should return it to CE-Compass. They have a 30 day return policy and a 15% re-stocking fee but if you prove it is a knock-off I think they might wave that (assuming they are reputable). If you decide to return it let us know the outcome.
