Flip the laptop over and open the lid so that the keyboard side is facing upwards.

Use a plastic pry tool to pry open the tabs holding the top panel on around all sides of the laptop.

Once all the tabs are free, carefully lift up the top panel to open it slightly.

Do not lift the top panel up too much or with excessive force since there are delicate ribbon cables on the inside that need to be disconnected before the assembly can be detached.
