[QUOTE="CyberSimian, post: 1295077, member: 141969"] To be clear, TV Server runs as a service, and hence runs all of the time. It is TV Server that knows when a recording is due, and which starts the recording. There is a system flag that TV Server switches on when a recording starts, and this flag tells Windows that the system must not sleep or hibernate. The relevant function is [URL='https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-setthreadexecutionstate']SetThreadExecutionState()[/URL]. If this flag is switched on, the system won't sleep, and won't hibernate after the hibernation timeout has expired. However, the system will hibernate if requested explicitly by the user, and will shutdown if requested by the user. If sleep is requested by the user, the system will transition to away mode (if that mode has been enabled by the user), and the system will sleep when the flag is switched off by TV Server when the recording has finished. -- from CyberSimian in the UK [/QUOTE]
