17 Advanced Configuration and Power Interface (ACPI) support for
18 Linux requires an ACPI compliant platform (hardware/firmware),
19 and assumes the presence of OS-directed configuration and power
20 management (OSPM) software. This option will enlarge your
21 kernel by about 70K.
22
23 Linux ACPI provides a robust functional replacement for several
24 legacy configuration and power management interfaces, including
25 the Plug-and-Play BIOS specification (PnP BIOS), the
26 MultiProcessor Specification (MPS), and the Advanced Power
27 Management (APM) specification. If both ACPI and APM support
28 are configured, whichever is loaded first shall be used.
29
30 The ACPI SourceForge project contains the latest source code,
31 documentation, tools, mailing list subscription, and other
32 information. This project is available at:
33 <http://sourceforge.net/projects/acpi>
34
35 Linux support for ACPI is based on Intel Corporation's ACPI
36 Component Architecture (ACPI CA). For more information see:
37 <http://developer.intel.com/technology/iapc/acpi>
38
39 ACPI is an open industry specification co-developed by Compaq,
40 Intel, Microsoft, Phoenix, and Toshiba. The specification is
41 available at:

57 ---help---
58 This option adds support for ACPI suspend states.
59
60 With this option, you will be able to put the system "to sleep".
61 Sleep states are low power states for the system and devices. All
62 of the system operating state is saved to either memory or disk
63 (depending on the state), to allow the system to resume operation
64 quickly at your request.
65
66 Although this option sounds really nifty, barely any of the device
67 drivers have been converted to the new driver model and hence few
68 have proper power management support.

181 support some Medion laptops (such as 9675 for example). It makes all
182 the extra buttons generate standard ACPI events that go through
183 /proc/acpi/events, and (on some models) adds support for changing the
184 display brightness and output, switching the LCD backlight on and off,
185 and most importantly, allows you to blink those fancy LEDs intended
186 for reporting mail and wireless status.
187
188 Note: display switching code is currently considered EXPERIMENTAL,
189 toying with these values may even lock your machine.

223 their lack of a BIOS setup menu and APM support.
224
225 On these machines, all system configuration is handled through the
226 ACPI. This driver is required for access to controls not covered
227 by the general ACPI drivers, such as LCD brightness, video output,
228 etc.
229
230 This driver differs from the non-ACPI Toshiba laptop driver (located
231 under "Processor type and features") in several aspects.
232 Configuration is accessed by reading and writing text files in the
233 /proc tree instead of by program interface to /dev. Furthermore, no
234 power management functions are exposed, as those are handled by the
235 general ACPI drivers.
