Disclosed herein is system for buffering processor interrupts from active input devices, such as Bluetooth devices, so that they are aligned with a video refresh rate. The system may include a processor that operates in a first operating mode (e.g., a low power mode) and, in response to an interrupt request, switch to a second operating mode (e.g., a higher power mode). The first operating mode may be different from the second operating mode (e.g., each with a different level of power consumption). The system may also include a video subsystem, in communication with the processor, that provides video information at a refresh rate. The system may also include an input subsystem, such as a wireless communication system, in communication with the processor, that receives an activity trigger representing an activity of a input device, such as a human input device, and provides, based on the refresh rate, the activity trigger to the processor as the interrupt request.
