    • In place of reusing old, worn out feet on your device, 8 mm rubber furniture pads can be a good substitute.

    • Peel a pad away from its backing, align it over a foot cavity, and press to secure.

    • Use a T5 Torx driver to remove the four 3 mm screws in the foot cavities securing the upper case to the device.

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your laptop.

    • During reassembly, don't over-tighten these screws—they strip easily.

  7. Microsoft Surface Laptop 3 13.5" Motherboard Replacement, Open the display: adım 8, 3 resimden 1. Microsoft Surface Laptop 3 13.5" Motherboard Replacement, Open the display: adım 8, 3 resimden 2. Microsoft Surface Laptop 3 13.5" Motherboard Replacement, Open the display: adım 8, 3 resimden 3.
