    • Remove the eight 4mm Phillips #0 screws.

    • Remove the two 6mm Phillips #0 screws.

    There are two tabs on the battery opposite the connector side that need to be inserted into the retention slots or the battery won’t sit flat. Need to do this before reinserting the battery screws.

    Also, I found that #00 Phillips works best on the 4mm screws.
