Answer to: Can't get into it to upgrade the RAMI had the same issue, it was like there was another screw, close to where the battery connector was. I watched this video and it looked like the rear cover should just slip off with ease. It was a simple solution in the end, you need to insert a plastic card (or Plastic Opening Tool) at the rear of the unit and coax it with a bit of jimmying. You will hear a pop/snap when you hit the sweet spot and the case it easily come off. I wanted to replaced the HDD with a SSD. 1. Pull out the rubber grommets. 2. Lift the two rubber tabs and pull them away from the SATA connector. With the rubber cradle out, remove one of the corners and it will easy to remove the HDD. Replace and reinsert by pushing the front of the SSD back towards the SATA connector.
