Abstract: In some examples, a connection apparatus includes a first connector assembly to engage with a second connector assembly, where the first connector assembly is included in one of a support stand and an electronic device, and the second connector assembly is included in another one of the support stand and the electronic device. The first connector assembly includes a floating connector block, an electrical contact on the floating connector block, and a biasing assembly engaged with the floating connector block to urge the floating connector block towards the second connector assembly when the second connector assembly is engaged with the first connector assembly to achieve a spring-loaded engagement of the electrical contact with an electrical contact of the second connector assembly.

Abstract: An example computing device includes a power switch, a power management device to control a power state change of the computing device based on a command from a power control device, and a controller. The controller is to, in response to receiving a power control request message from an external device, change the power control device from the power switch to the external device.

Abstract: A fixing structure for an electronic card is suitable for mounting a long electronic card or a short electronic card within a housing. The fixing structure includes a pressing plate, a locking slice, and a locking member. Two ends of the pressing plate have two buckling portions. The locking slice connects an end of the pressing plate and has a locking hole. Besides, the locking slice leans against the housing. The locking member passes through the locking hole and is fixed into a first fixing hole or a second fixing hole. When the locking hole corresponds to the first fixing hole, the two buckling portions are fixed onto a free end of the long electronic card. When the locking hole is corresponding to the second fixing hole, the two buckling portions are fixed onto a free end of the short electronic card.
