An arc structure 423 can be formed on a lateral side of the protecting cover 42, and curvature of the arc structure 423 can match curvature of a casing of the portable computer 32 preferably. As the curvature of the arc structure 423 matches the curvature of the casing of the portable computer 32, the arc structure 423 can be for guiding the portable computer 32 to tightly contact on the protecting cover 42 when the portable computer 32 is placed against the protecting cover 42, so as to increase stability of the portable computer 32. Furthermore, the external extension 34 can further include at least one speaker module 46 disposed on the second area 362 of the base 36 and electrically connected to the pin set 40, and at least one magnetic component 48 disposed on the base 36, such as disposing on two sides of the base 36. The speaker module 46 can be an external speaker of the portable computer 32, and audio signals can be transmitted from the portable computer 32 to the speaker module 46 via the pin set 40 for preferred acoustic quality. A metal component with magnetic attraction can be disposed on the casing of the portable computer 32, so that the external extension 34 can utilize the magnetic component 48 to attract the portable computer 32, so as to combine the external extension 34 with the portable computer 32 for convenience.


Operating method of the computer system 30 is described as follows. When the computer system 30 is not in use, the user can rotate the holding component 44 relative to the base 36 to place on the second area 362 of the base 36, and rotate the protecting cover 42 relative to the base 36 at the first position to place on the keyboard module 38. And then the user can utilize the magnetic component 48 to combine the external extension 34 with the portable computer 32, so as to minimize volume of the external extension 34 and the computer system 30 for convenient carriage as shown in FIG. 2. On the other hand, the user separates the external extension 34 from the portable computer 32 as the computer system 30 begins in use. The holding component 44 is unfolded, and the protecting cover 42 pivots relative to the base 36 at the second position, as shown in FIG. 3. Meanwhile, the side of the protecting cover 42 contacts against the lateral side of the second area 362, and the other end of the holding component 44 can be wedged inside the fixing portion 421 of the protecting cover 42, so as to constrain the rotational movement of the protecting cover 42. Finally, the portable computer 32 is placed on the third area 363, a side of the portable computer 32 contacts against the protecting cover 42, and the other side of the portable computer 32 is electrically connected to the pin set 40, so that the signal generated by the external extension 34 can be transmitted to the portable computer 32, and assembly of the external extension 34 and the portable computer 32 is finished.
