Can't remove back cover for SSD upgrade
I recently bought an Asus Q552ub notebook from Best Buy. I want to replace the hard drive with an SSD. I have the iFixit toolkit, and the T5 screws around the edge came off without issue. Using the iFixit plastic tabs, I loosed up all the way around the edges without issue.
The problem is, the back plate appears to be stuck right in the middle of the laptop. Pulling up from any free edge hangs at the same spot in the middle. There are no other screws, but I'm afraid to force it and bend the back aluminum plate or break something inside. All videos and pictures I found on the web and youtube for similar devices in the family, like the Q551, show it just coming right off. Peaking through the various loose edges with a flashlight doesn't reveal much.
Is it possible it is glued or something in the middle? So far as I know, the Q552 is just like the Q551, except it is exclusive to Best Buy. The manual shows nothing about the upgrade process. I'm at a loss. Help!
