Abstract: In example implementations, an apparatus is provided. The apparatus includes an interface, a previous generation carrier connected to the interface, a controller communicatively coupled to the interface, and a basic input/output system (BIOS). The previous generation carrier includes a current generation memory card. The controller is to detect the previous generation carrier. The BIOS is to set the interface to operate at a speed associated with the previous generation carrier in response to detection of the previous generation carrier.

Abstract: In example implementations, an apparatus is provided. The apparatus includes an accelerometer, a plurality of fan blades, a coil magnet and a processor. The accelerometer is coupled to a motor to measure an amount of vibration. The plurality of fan blades is coupled to the motor. Each one of the plurality of fan blades comprises a magnet. The coil magnet is coupled to a fan housing that encloses the motor, the plurality of fan blades and the accelerometer. The processor is communicatively coupled to the motor, the accelerometer, and the coil magnet. The processor activates the coil magnet to control a balance of the plurality of fan blades in response to an amount of vibration measured by the accelerometer that exceeds a threshold.

Abstract: The present subject matter relates to backlight keyboards. In an example implementation of the present subject matter, backlight keyboards and methods of fabricating lighting units for such backlight keyboards are described. In an example, a backlight keyboard includes a substrate and a plurality of Light Emitting Diodes (LEDs) disposed on the substrate. The backlight keyboard further includes a printed circuit disposed on the substrate, where the printed circuit comprises of a plurality of electrical connections to provide electric current to the plurality of LEDs, and where width of each of the plurality of electrical connections is predefined to control brightness of a corresponding LED from amongst the plurality of LEDs.
