There are 14 different types of screws, using 3 different driver sizes. Also there are 138 tapped holes and 10 brass inserts in this laptop. PennEngineering can provide the screws and inserts currently used with no change to the design.
There are cost savings opportunities by changing many of the threaded joints to TackSerts. 56 pierces of M1.2 x 2 screws can be replaced with microPEM Micro TackSerts®. Replacing the 56 pierces M1.2 threads in the magnesium chassis with unthreaded holes would result in substantial cost saving opportunities.
In total 13 sets of screw-washer assemblies be used for screws can move up and down once disengaged from the mating hardware without forcing the joint apart. As a possible solution, Micro versions of SCB and SCBJ can be used as a replacement for screw-washer assemblies that hardware be constrained.
Below are certain alternatives featuring several PEM® fasteners that can help achieve better functionality and cost savings:

PEM can provide all existing micro screws for the application without any change to the design.
PEM has license with Torx®, Torx Plus® driver and self-tapping thread patent such as TAPTITE®,
FASTITE®, REMFORM®, and REMFORM “F” ®, PT® and Delta PT® (Nickel and Zn-Ni plating with different color).
Currently tapping magnesium chassis and threading micro screws into the tapped holes.
TackSert fasteners eliminate the tapping step and replace the screws. To be installed with axial pressure for a lower total installed cost.
PEM provides aluminum SI inserts as an excellent lead free option for considerable weight reduction.

Micro versions of SCB and SCBJ can be used as a replacement for screw-washer assemblies that hardware be constrained.
The SCB and SCBJ offer an economical solution for retained screws. The SCB and SCBJ will provide axial float, meaning it can
move up and down once disengaged from the mating hardware without forcing the joint apart.
