An information handling system includes a chassis, a filter, a force sensing resistor, and a baseboard management controller. The chassis includes a bezel. The filter is in physical communication with the bezel of the chassis. The force sensing resistor is in physical communication with the bezel and with the filter. The baseboard management controller communicates with the force sensing resistor and receives a voltage level from the force sensing resistor. Based on the voltage level, the baseboard management controller determines a clogged level for the filter. The baseboard management controller determines whether the clogged level is greater than a threshold level. In response to the clogged level being greater than the threshold level, the baseboard management controller determines that the filter needs to be replaced and provides a filter clogged message.

A circuit board may include a traditional via electrically coupled to a first layer of the circuit board and coupled to a second layer of the circuit board and a slotted via formed within the circuit board proximate to the traditional via, the slotted via comprising an opening through a first surface and a second surface of the circuit board and a layer of conductive material formed on interior walls of the opening.

Slotted vias for circuit boards

A switch includes an actuator for moving the switch from an OFF position to an ON position. A resistor is connected in series between a first terminal and a second terminal, and limits inrush current that flows when the switch is moved from the OFF position to the ON position.

An information handling system includes first and second printed circuit boards (PCBs), and first and second connectors. The first PCB includes a first top surface, a first bottom, and a first plurality of side surfaces extending between the first top and first bottom surfaces. The first connector is embedded within the first PCB, and extends from the first bottom surface toward the first top surface. A first height of the first connector is substantially equal to a first thickness of the first PCB. The second PCB includes a second top surface, a second bottom, and a second plurality of side surfaces extending between the second top and second bottom surfaces. The second connector is embedded within the second PCB, and extends from the second bottom surface toward the second top surface. A second height of the second connector is greater than a second thickness of the second printed circuit board.
