A cable (and heat sink) for radiating heat includes a heat conducting and radiating member for conducting heat in a longitudinal direction of the cable and radiating the conducted heat. The heat sink includes the cable for radiating heat, and a heat connecting member for thermally connecting a heat generator to the cable.

Described is a security mechanism effective in various combinations of a notebook PC and various extend units. An extend unit includes a security slot for attaching a cable lock, a security select which has a plurality of select positions and the select position of which is fixed when the cable lock is attached to the security slot. A linking unit is included for interlocking with the security select switch, disabling a release switch to be operated with fixing the release switch of a subsystem holding bay when the security select switch is positioned at a first select position, disabling the release switch and an eject switch, separating the notebook PC from the extend unit, to be operated when the security select switch is positioned at a second select position, and enabling the release switch and eject switch to be operated without fixing the release switch and eject switch when the security select switch is positioned at a third select position.

A battery compartment latch mechanism holds a battery in either a fully loaded or a partially loaded position. The partially loaded position prevents the battery from slipping out of the battery compartment when the battery is being ejected. To hold the battery in the fully loaded position, a latch (66) at one end of a lever (60) is urged by a cantilever spring (72) into engagement with a battery recess (50). To disengage the latch from the recess, the lever is rotated manually by moving a handle (84) located at another end of the lever. As the battery is being withdrawn, a plunger (90) engages the battery recess to prevent the battery from slipping out. To fully remove the battery, the user forcibly urges the battery out of the compartment. Because the side walls (104) of the plunger are sloped, forcing the battery outward causes the plunger to be depressed, thereby disengaging the plunger from the battery recess. Thus, even if the battery is being ejected when the battery compartment is in an inclined or non-horizontal position, the battery does not fall out of the compartment.
