50 This option adds support for ACPI suspend states.
51
52 With this option, you will be able to put the system "to sleep".
53 Sleep states are low power states for the system and devices. All
54 of the system operating state is saved to either memory or disk
55 (depending on the state), to allow the system to resume operation
56 quickly at your request.
57
58 Although this option sounds really nifty, barely any of the device
59 drivers have been converted to the new driver model and hence few
60 have proper power management support.
61
62 This option is not recommended for anyone except those doing driver
63 power management development.
