Note 2: If pressing and holding the D key at Step 4 doesn't work, start again at Step 3 and, at Step 4 press and hold both the Option D keys instead. Make sure you record the results clearly so you know what they were for each of the six memory configurations. At completion you should have run the Apple Hardware Test six times.

You could test for this by applying some pressure on the bottom case as you start up or wake the computer. In many cases it was caused by pressure, over time, on the bottom of the MBP which in turn placed pressure on the logic board. Regardless, there was an issue with logic boards not being able to address the RAM. There was a common problem with some MBP models, but this predominantly affected 13" pre-2012 models. Unfortunately, not all of the possible startup tones are listed on that page, but identifying the correct tone helps narrow down your problem! Near enough is not good enough! If your startup tone does not match exactly one of the ones listed, please comment back and say so and describe which one it is closest to and what the difference is.

The first step would be to check out About Mac computer startup tones and identify which one of these startup tones is the one you're experiencing with your Mid-2012 MBP. They'll likely spend more time with your machine hands-on to get to the bottom of it. I would try a non-Apple Store location this time as they aren't as busy and aren't trying to shuffle you out in a set period of time to get to their next appointment. Not to bash Apple Stores but they're busy places. You can find one using this link (click on the 'Service' block): Since the genius bar proved to be of no help I would strongly recommend something called an Apple Authorized Service Provider for a second opinion.

What leads me to believe this is 1) you've tested multiple sticks of RAM and the issue still occurs, 2) you believe it's happening after transport so things could be shaking loose temporarily, 3) the genius bar couldn't find an issue when running tests meaning maybe when they were testing it the weary solder points just happened to have settled and were making sufficient contact at the time. What you're describing to me sounds a lot like a possible solder point issue between the RAM slots and the logic board itself, unfortunately. The problem is that most people assume that only the actual RAM itself can trigger the beeps when in fact there's a chance that it could be the RAM slots causing the issue. 3 beeps upon startup definitely signals a RAM issue.
