A method for assembling an electronic device, wherein the electronic device comprises a cover, a base comprising a first shell defining a plurality of blind holes and positioning hooks, and a second shell defining a plurality of first through holes;

• and a hinge member comprising a rotation portion and a fixed portion hinged to the rotation portion, the fixed portion defining a plurality of second through holes free of inner thread defined therein;
• the method comprising:
• aligning the second through holes of the fixed portion with the blind holes of the first shell, engaging the fixed portion with the positioning hooks to fix the fixed portion on the first shell, and fastening the fixed portion to the first shell;
• aligning the first through holes of the second shell with the second through holes of the fixed portion of the hinge member, and placing the second shell on the first shell;
• extending screws through the first through holes and the second through holes to cut inner thread in an inner surface of the second through holes;
• and
• inserting distal ends of the screws into the corresponding blind holes with debris generated during cutting the inner thread being accommodated in the blind holes.
