Step 1: Please place unit face down on table.
Step 2: Remove 2 plastic covers on back stand by prying up on the covers. Step 3: Remove the 6 screws holding the back stand on.
Step 4: Grab back cover at the top right corner by the silver and black. Push on the black plastic and pull up ******* the cover and it will pop right off.
This works - I am not a tec and I did it

You were right by removing the support bar, that's the first step. Now all you have to do is use a small flat head screw driver and pry open the case on the edge between the black and silver plastic. Don't get to aggressive, take your time going all the way around, it should just pop off. Have fun.

Should be compartment covers on the bottom of laptop. 2 smaller covers, 1 is wireless and the other is RAM. Power down your laptop, unplug power cord and remove battery. With cover removed and grounding yourself to prevent static electricity transfer, see the holders for the RAM undo them and pull the old RAM out and replace with new. Be sure of compatibility. The new should install with snapping sound when the holders are correct. Reinstall the cover and battery plus power cord. Upon powering it up it should recognize the new hardware. Hope that helps..
