Abstract: In one example, touchpad assembly is disclosed, which may include a bottom cover, a horizontal elastic member flexibly positioned on the bottom cover, a balancing bar disposed on the bottom cover and substantially parallel to the horizontal elastic member, and a metal dome. The metal dome may include a first end fixedly connected to the bottom cover via a first fixture, and a second end to hold the horizontal elastic member and the balancing bar such that the balancing bar is flexibly engaged with the bottom cover. The balancing bar, the metal dome, and the horizontal elastic member may control a flexure of a touchpad when the touchpad is pressed.

Abstract: Examples for controlling an operating speed of a cooling device based on an operating mode of a processing unit, are described. In an example, a current value of a monitored current signal is determined. Based on the comparison of the current value with a predefined threshold value, a switch in an operating mode of the processing unit is determined. Thereafter, the computing device may be caused to increase the operating speed of the cooling device to a designated speed.

Abstract: An example redundant power supply system comprises a power supply input to receive power from a power supply; a buck-boost converter coupled to the power supply input; and a controller coupled to the buck-boost converter. The controller is to receive a power supply identification signal from the power supply. The controller is also to enable or disable the buck-boost converter based on the power supply identification signal.

Abstract: In one example, an adapter card may include a circuit board having a male interface to be inserted into a discrete graphics card slot and a peripheral component interconnect express (PCIe) slot to communicatively couple a PCIe device. Further, the adapter card may include a voltage converter circuit disposed on the circuit board to convert a first voltage associated with the discrete graphics card slot to a second voltage corresponding to the PCIe device and a level shifter circuit disposed on the circuit board to modify a signal level in the discrete graphics card slot to a signal level in the PCIe device.

Abstract: Example implementations relate to power supply controllers. In some examples, a controller can include instructions to: set a power threshold for a power supply coupled to a computing component when the computing component is operating in a first state, determine when the computing component is alternating from the first state to a second state, and allow the power supply to exceed the power threshold for a fixed period of time in response to the computing component alternating from the first state to the second state.

Abstract: In example implementations, a computing device is provided. The computing device includes an expansion interface, a first device, a second device, and a processor communicatively coupled to the expansion interface. The expansion interface includes a plurality of slots. Two slots of the plurality of slots are controlled by a single reset signal. The first device is connected to a first slot of the two slots and has a feature that is compatible with the single reset signal. The second device is connected to a second slot of the two slots and does not have the feature compatible with the single reset signal. The process is to detect the first device connected to the first slot and the second device connected to the second slot and disable the feature by preventing the first slot and the second slot from receiving the single reset signal.

Abstract: In example implementations, a computing device is provided. The computing device includes an expansion interface, a memory, a controller, and a configuration change module. The expansion interface includes a plurality of slots to connect to a respective add-in card and a re-timer to control an operation of the plurality of slots. The memory is to store a firmware that sets a configuration of the plurality of slots, wherein the re-timer is to control the operation of the plurality of slots in accordance with the configuration set by the firmware. The controller is to control operation of the expansion interface. The configuration change module is to change the configuration of the plurality of slots when a change in a number of connected add-in cards is detected.
