    • Using a spudger with your right hand, put pressure on one of the upper mouse buttons.

  • Here is your second chance to modify your RAM configuration. As before, there are two DDR3 SDRAM slots. Here they are stacked on each other, not side by side like the bottom. You may install up to 8 GB in each slot, allowing for 16 GB of RAM total.

    • If your computer has a dual-core processor, these are the RAM slots that will work.

  • Before the top casing can be removed, there are two more things to do.

    • A fingerprint scanner is optional on this laptop - mine has it - and it is connected to the motherboard on the same ribbon as the trackpad.

  • Use a plastic opening tool to lift up the ZIF connector.

  • Pull the cable out of the connector.
