Information handling system (IHS) heatsinking systems and methods may employ a thermally conductive compression attached memory module (CAMM) bolster plate affixed to one surface of a circuit board of the CAMM, between a central processing unit (CPU) of the IHS and memory devices mounted on the CAMM, to provide compression between the CAMM and a z-axis compression connector and to capture and dissipate heat from the CPU and the memory devices. Spacing between the CPU and the DIMM may enable this capture and dissipation of heat from the CPU. The bolster plate may be configured to receive at least one conductive fastener that bears on the bolster plate and presses the CAMM to the z-axis compression connector, and to conductively thermally couple the CAMM and bolster plate to a ground plane of a system printed circuit board (PCB) mounting the CPU and the CAMM.

The expansion card includes a circuit board assembly and a fixing plate. The circuit board assembly is fixed to a side of the fixing plate. The circuit board assembly is electrically connected to the motherboard and is fixed to the chassis via the fixing plate. A side of the support supports a side of the circuit board assembly that is located farthest from the fixing plate. A side of the support that is located farthest from the circuit board assembly is fixed to the motherboard and the chassis.

Securing a riser cage and/or electronic components coupled thereto within an information handling system can be accomplished using a riser cage apparatus. The riser cage may be configured to removably secure the electronic components to a surface of the information handling system using one or more fasteners configured to couple the riser cage to a surface of a chassis. The one or more fasteners may comprise a protrusion configured to engage a pin coupled to the surface. The protrusion of the one or more fasteners may be movable relative to the riser cage between a first locked position in which the pin coupled to the surface is engaged by the protrusion and a second unlocked position in which the pin coupled to the surface is not engaged by the protrusion.

A circuit board includes a board body, a card slot, a release structure, and a transmission mechanism. The card slot is disposed on the board body and adapted for inserting an expansion card. The release structure is rotatably disposed beside the card slot. The transmission mechanism includes a contact part and a stressed part that are linked to each other, wherein the contact part is connected to the release structure. When the stressed part receives an external force, the contact part is moved correspondingly, so that the release structure is rotated relative to the card slot, thereby releasing the expansion card.

The buckle base is in a generally U-shaped form. The buckle base includes a first leg, a second leg, and a bridge therebetween. The first and second legs are connected to the bridge. The buckle-fixing pin forms a longitudinal slot therein.

A fixing device is provided for fixing an expansion card in an electronic device. The fixing device includes a supporting base, a fastening element and an actuating element. The supporting base includes a sliding rail. The sliding rail is located under the expansion card. The sliding rail includes plural first positioning structures. The fastening element includes a sliding part and a locking part. The sliding part is movably installed on the sliding rail. The locking part is protruded from the sliding part. The expansion card is arranged between the locking part and an expansion port of the electronic device. The actuating element includes a pressing part and an elastic part. The pressing part is connected with the sliding part through the elastic part. The pressing part includes a second positioning structure. The second positioning structure is detachably engaged with one of the plural first positioning structures.

A printed circuit (PC) card apparatus can, in an absence of external power provided to a Peripheral Component Interconnect Express (PCIe) PC card, prevent and detect unauthorized access to secure data stored on a memory device mounted on the PCIe PC card. The PCIe card includes a primary battery to supply, when external power is disconnected from the PCIe card, power to an electronic security device mounted on the PCIe card. The PC card apparatus also includes a PCIe edge connector protector enclosing electrically conductive fingers of a PCIe edge card connector. The PCIe edge connector protector includes a hidden supplemental charge storage device integrated into the PCIe edge connector protector. The PCIe edge connector protector also includes electrically conductive contacts to transfer supplemental power from the supplemental charge storage device to the electronic security device.

A chassis for housing a computing device of an information handling system includes a receiving portion of an expansion card receiver that receives an expansion card and operably connects the expansion card to another component of the computing device while the expansion card is received by the receiving portion. The chassis further includes a management portion of the expansion card receiver that receives a force from a user and, in response to receiving the force: transitions the management portion from a first state to a second state. In the first state, a handle, that enables the expansion card to be removed from the chassis is disposed inside of the management portion and the expansion card receiver is locked to the chassis. In the second state, the handle is disposed outside of the management portion and the expansion card receiver is unlocked from the chassis.

Techniques are disclosed relating to a locking pin used to secure components in an electronics module. For example, in some embodiments an electronics module includes a housing lower part that includes a lower receiving element and a housing upper part that includes an upper receiving element that is aligned with the lower receiving element. In various embodiments, a locking pin may be used to connect a circuit board in the electronics module. For example, in some embodiments the circuit board includes at least one lead-through opening and the circuit board is connected to the housing lower part via the locking pin that is inserted in a positive-locking manner through the lead-through opening into the lower receiving element. Further, in some embodiments, an upper pin section of the locking pin may be inserted into an upper receiving element of the housing upper part in a positive-locking manner.
