There are two screws beside in each rubber dings, 4 screws, inside the compartment where the hdd and ram are, 2 screws inside the battery compartment, took them off but the back panel wont come out. I shoot an email to ASUS support, as they might be able to give us instruction.
I am not sure if the ODD screw can be access at the back cover or under the keyboard?
Thanks!
