with hotkey_report_mode.
+Brightness hotkey notes:
+
+These are the current sane choices for brightness key mapping in
+thinkpad-acpi:
+
+For IBM and Lenovo models *without* ACPI backlight control (the ones on
+which thinkpad-acpi will autoload its backlight interface by default,
+and on which ACPI video does not export a backlight interface):
+
+1. Don't enable or map the brightness hotkeys in thinkpad-acpi, as
+ these older firmware versions unfortunately won't respect the hotkey
+ mask for brightness keys anyway, and always reacts to them. This
+ usually work fine, unless X.org drivers are doing something to block
+ the BIOS. In that case, use (3) below. This is the default mode of
+ operation.
+
+2. Enable the hotkeys, but map them to something else that is NOT
+ KEY_BRIGHTNESS_UP/DOWN or any other keycode that would cause
+ userspace to try to change the backlight level, and use that as an
+ on-screen-display hint.
+
+3. IF AND ONLY IF X.org drivers find a way to block the firmware from
+ automatically changing the brightness, enable the hotkeys and map
+ them to KEY_BRIGHTNESS_UP and KEY_BRIGHTNESS_DOWN, and feed that to
+ something that calls xbacklight. thinkpad-acpi will not be able to
+ change brightness in that case either, so you should disable its
+ backlight interface.
+
+For Lenovo models *with* ACPI backlight control:
+
+1. Load up ACPI video and use that. ACPI video will report ACPI
+ events for brightness change keys. Do not mess with thinkpad-acpi
+ defaults in this case. thinkpad-acpi should not have anything to do
+ with backlight events in a scenario where ACPI video is loaded:
+ brightness hotkeys must be disabled, and the backlight interface is
+ to be kept disabled as well. This is the default mode of operation.
+
+2. Do *NOT* load up ACPI video, enable the hotkeys in thinkpad-acpi,
+ and map them to KEY_BRIGHTNESS_UP and KEY_BRIGHTNESS_DOWN. Process
+ these keys on userspace somehow (e.g. by calling xbacklight).

+
+ echo '<LED number> on' >/proc/acpi/ibm/led
+ echo '<LED number> off' >/proc/acpi/ibm/led
+ echo '<LED number> blink' >/proc/acpi/ibm/led
+
+The <LED number> range is 0 to 7. The set of LEDs that can be

+mapping:
0 - power
1 - battery (orange)
2 - battery (green)
- 3 - UltraBase
+ 3 - UltraBase/dock
4 - UltraBay
+ 5 - UltraBase battery slot
+ 6 - (unknown)
7 - standby
All of the above can be turned on and off and can be made to blink.
+sysfs notes:
+
+The ThinkPad LED sysfs interface is described in detail by the LED class
+documentation, in Documentation/leds-class.txt.
+
+The leds are named (in LED ID order, from 0 to 7):
+"tpacpi::power", "tpacpi:orange:batt", "tpacpi:green:batt",
+"tpacpi::dock_active", "tpacpi::bay_active", "tpacpi::dock_batt",
+"tpacpi::unknown_led", "tpacpi::standby".
+
+Due to limitations in the sysfs LED class, if the status of the LED
+indicators cannot be read due to an error, thinkpad-acpi will report it as
+a brightness of zero (same as LED off).
+
+If the thinkpad firmware doesn't support reading the current status,
+trying to read the current LED brightness will just return whatever
+brightness was last written to that attribute.
+
+These LEDs can blink using hardware acceleration. To request that a
+ThinkPad indicator LED should blink in hardware accelerated mode, use the
+"timer" trigger, and leave the delay_on and delay_off parameters set to
+zero (to request hardware acceleration autodetection).
