First of all, congratulations for this amazing work you developers are doing on Haiku, i’ts getting really good!
Now, I would like to know about the ACPI support on Haiku, because i can’t put my computer on Standby mode (S3 Sleep or Suspend to RAM) and I could not find anything about it on Haiku menu or preferences either.
So, I ask you, is there any support for any ACPI power saving mode? Are you planning to implement that?
S0/Working System is on. The CPU is fully up and running; power conservation operates on a per-device basis.
S1 Sleep System appears off. The CPU is stopped; RAM is refreshed; the system runs in a low power mode.
S2 Sleep System appears off. The CPU has no power; RAM is refreshed; the system uses a lower power mode than S1.
S3 Sleep (Standby) System appears off. The CPU has no power; RAM is in slow refresh; the power supply is in a reduced power mode. This mode is commonly referred to as ‘Suspend To RAM’.
S4 Hibernate System appears off. The hardware is completely off, but system memory has been saved as a temporary file onto the harddisk. This mode is also referred to as ‘Suspend To Disk’.
S5/Off System is off. The hardware is completely off, the operating system has shut down; nothing has been saved. Requires a complete reboot to return to the Working state.
