The cover is disposed to the base and includes a first cover body and a second cover body. The first cover body is capable of rotating about the base, and the second cover body is pivoted to the first cover body and is capable of rotating about the first cover body. The support piece is disposed to one side of the base and is capable of sliding relative to the base. When the support piece slides out of the side of the base and the second cover body flips to the side of the base, the second cover body leans against the support piece, and thus the first cover body can be used for supporting a tablet computer or a handheld communication device.

Abstract: A method of pairing a computer and a wireless electronic device includes the following steps. Firstly, a predetermined media access control address is received. A service set identifier of a wireless local network is established according to the predetermined media access control address. At least one packet is received. Then, a judging step is performed to judge whether the media access control address of the first packet matches the service set identifier. Afterwards, a response packet is transmitted to the wireless electronic device. By recording the media access control address of the wireless electronic device, the wireless electronic device to be paired can be accurately paired with the computer. It is more time-saving by using the pairing method of the present invention because the time period of selecting a to-be-paired wireless electronic device is not necessary.
