All IBM AC adapters have this "IBM" three-color logo. The color of the three letters was pure red, green and blue. By comparing, the fake one is not pure as the original one. They looks more shallow, especially the letter M. if you didn't have an original IBM laptop AC adapter at hand, you can check it with the logo on the laptop top cover.
Another way is to examine the fake sticker on the bottom of the adapter. The real one is clearer of the printed text on it. But the fake one is pure white comparing with the gray real one.
The third is to have a look at the power cord socket parts; there is an apparent difference between the real and the fake.
