Conclusions and Summary

• The Acer Swift 7 computer is a intelligently designed device with reparability in mind. A lot of screws were discovered in the assembly, most of them received into tapped holes in the metal casing.

– Various screws in the assembly can be replaced with TackPins, TackSerts, or

microPEM® screws.

– The hinge pin can be replace with a direct solution provided by PEM.
