Better still:
Hold down L & R while turning it on, then press A to cycle through all the various tests, and see if it comes up with anything other than PASS for any of them.
If you tell him to do that he is going to come back freaked out and tell us the SuperCard was unable to find the test file and its going to waste both my time and his which is what I am doing right now. Not everything says "PASS" on the SuperCard self-test. And to the question user the SuperCard not being able to find the test file is normal. Look for anything else thats odd.
