An example implementation involves launching a power coordinator background process, the power coordinator background process having multiple client programs and establishing respective inter-process communication (IPC) mechanisms between the multiple client programs and the power coordinator background process. The implementation further involves receiving, via the established IPC mechanisms from the multiple client programs, messages indicating that the respective client program is ready to suspend, and determining that each client program of the multiple client programs is ready to suspend. The implementation further includes sending instructions to the operating system to kernel suspend. While in kernel suspend, the playback device detects a particular trigger to kernel resume and in response, performs a kernel resume."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Portable playback device power management","description":"Example techniques related to portable playback device power management.
