- ---help---
- This option adds support for ACPI suspend states.
-
- With this option, you will be able to put the system "to sleep".
- Sleep states are low power states for the system and devices. All
- of the system operating state is saved to either memory or disk
- (depending on the state), to allow the system to resume operation
- quickly at your request.
-
- Although this option sounds really nifty, barely any of the device
- drivers have been converted to the new driver model and hence few
- have proper power management support.
-
- This option is not recommended for anyone except those doing driver
- power management development.
