Abstract: A device for attaching a heat sink having a first and a second surface to an element generating heat in an electronic system, which element has an upper plane side contacting the first surface of the heat sink and a lower connector side connected to a printed circuit board, comprises a pair of holes formed on the upper plane side of the element at both sides of the heat sink attached to the element, a clip attached to the second surface of the heat sink having two hooked ends respectively connected with the pair of holes, a lever hinged to the clip, and a support hinged to the lever, wherein the lever is swung so as to cause the support to press or release the heat sink against or from the element. Preferably, the clip has a lever holding seat to hold a first fixing lug formed on the lever swung to cause the support to press the heat sink, thereby preventing the lever from inadvertent reverse swing.

Abstract: The present invention relates to the supporting legs of a portable computer. The legs can be rotated to raise the rear side of the computer and can be moved perpendicularly to their plane of rotation to allow various angles of rotation.

Abstract: An apparatus for securing a speaker to a portable computer including a speaker receiving recess adapted to receive a speaker therein and defined by an annular guide rib extending downwardly from a lower surface of a panel of a computer body, a speaker fixing member adapted to cover the speaker receiving recess, thereby upwardly supporting the speaker received in the speaker receiving recess, the speaker fixing member being coupled to the panel by a rotation thereof carried out in a selected left or right direction by a desired angle, and anti-loosening members each extending radially outwardly from the speaker fixing member, each of the anti-loosening members engaging with the lower surface of the panel in a state, in which it rotates in accordance with the rotation of the speaker fixing member, thereby preventing the speaker fixing member from rotating optionally from a state fixing the speaker fixing member.

Abstract: Disclosed is the improved locking assembly of a display panel in order to enlarge the display of a portable personal computer. A portable computer having a locking assembly coupled to hinging shafts including a setting member, a locking member connected and disconnected to the setting member to allow the cover to open or close, a rectangular aperture formed over the position where the hinging shaft is engaged, a fixing member for being coupled to the locking groove so as not to allow the hinged shaft to rotate, a handling member for being coupled to the fixing member and controlling its operation, and an elastic member for being coupled to the fixing member and pushing the fixing member toward the hinging shaft. Therefore, the portable computer having the locking assembly can provide a larger display in a limited space while the volume of the portable computer is not increased, and thereby leading to relieving consumers of complaints due to a small display.
