BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates to electronic devices, and more particularly to a portable electronic device having an adjustable height. 
         [0003]    2. Description of Related Art 
         [0004]    Portable electronic devices are widely used all over the world, because of their mobility and small size. A laptop is a typical portable electronic device, which usually includes a main unit with a keyboard, and a display unit pivotally connected to the main unit. The display unit is rotatable relative to the main unit to selectively locate in an open position and a closed position. When in the closed position, the display unit typically covers the keyboard of the main unit. When in the open position, the display unit is rotated away the keyboard of the main unit so that the keyboard and a screen provided in the display unit are exposed and viewable. The laptop may be used to listen to music, watch movies, and so on. However, the height of the display unit or the inclined angle of the keyboard may be non-adjustable according to user preference. 
         [0005]    Therefore, a need exits for providing a portable electronic device that can conveniently adjust the height of the portable electronic device.

     DETAILED DESCRIPTION 
       [0008]    Referring to  FIGS. 1 and 2 , a portable electronic device in accordance with a first exemplary embodiment is a computer assembly  100 . The computer assembly  100  includes a laptop computer  40  and a stand  30  attached to the laptop computer  40  for adjusting the height of the laptop computer  40 . The laptop computer  40  includes a main unit  10  and a display unit  20  pivotally attached on the main unit  10 . The stand  30  is located at the bottom of the main unit  10 . The display unit  20  includes a screen  21  for displaying information of the laptop computer  40 . 
         [0009]    The main unit  10  includes six walls, e.g. a top wall  16 , a bottom wall  17 , a front wall  11 , a rear wall  13 , and two side walls  12  and  14 . The display unit  20  is pivotally connected to a first corner  18  of the main unit  10  defined by the top wall  16  and the rear wall  13 . The display unit  20  is thus able to be on top of the main unit  10  or rotate to a predetermined angle relative to the main unit  10 . A keyboard  15  is disposed at the top wall  16 . Two positioning portions  121  are formed on the two side walls  12  and  14  correspondingly. Each of the positioning portions  121  may be a stub protruding from the corresponding side wall  12  or  14 . 
         [0010]    The stand  30  is used for adjusting the height of the display unit  20  and an inclined angle of the keyboard  15 . The stand  30  includes a seat  31  and two rods  33 . 
         [0011]    The seat  31  may be a flat sheet. The seat  31  is located under the main unit  10  for supporting the main unit  10 , and is pivotally connected to a second corner  19  of the main unit  10  defined by the front wall  11  and the bottom wall  17 . The seat  31  defines two elongated grooves  311  along a front-rear direction at opposite sides. 
         [0012]    The two rods  33  are symmetrically disposed at the two side walls  12  and  14  of the main unit  10  correspondingly. Each rod  33  includes a positioning end  331  which is inserted in the groove  311 , and a pivoting end  332  which is pivotally rotatable on the positioning portion  121 . The positioning end  331  is slidable along the groove  311  to adjust its location in the groove  311 . The pivoting end  332  defines a pivoting hole  334  for receiving the positioning portion  121 . 
         [0013]    When the stand  30  is in a normal state, the main unit  10  is folded on the seat  31 , and the positioning end  331  is located in a first location of the groove  311 , such as a first end of the groove  311 . When the height of the display unit  20  or the inclined angle of the keyboard  15  needs to be adjusted, the stand  30  can be changed from the normal state to an adjusted state. The positioning end  331  is forced to move from the first location to a second location of the groove  311 , such as a middle of the groove  311 . The main unit  10  is thus pushed by the rods  33  to rotate relative to the seat  31 . A triangular shaped structure is thus obtained cooperatively by the rods  33 , the seat  31 , and the main unit  10 . Therefore, the display unit  20  is adjusted to an appropriate height, and/or the keyboard  15  of the main unit  10  is adjusted to an appropriate inclined angle relative to the seat  31 , the positioning end  331  may be fixedly positioned in the groove  311  by friction or abutting force between the positioning end  331  and the groove  311 . 
         [0014]    It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the present disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
