+Advanced Power Management
+CONFIG_APM
+ This driver provides APM support on machines with an APM-compliant 32-bit
+ BIOS. Specifically, the time will be reset after a USER RESUME
+ operation, the /proc/apm device will provide battery status information,
+ and ioctls are provided to put the machine in STANDBY or SUSPEND mode.
+ This is most useful on laptops with a compliant BIOS.
+
+Ignore USER SUSPEND
+CONFIG_APM_IGNORE_USER_SUSPEND
+ This option will ignore USER SUSPEND requests. On machines with a
+ compliant APM BIOS, this is never what you want to do. However, this is
+ necessary on the NEC Versa M series, which generates these when resuming
+ from SYSTEM SUSPEND. Enabling this on other laptops may cause the laptop
+ to generate a CRITICAL SUSPEND when an appropriate USER SUSPEND is
+ ignored -- this may prevent the APM driver from updating the system time
+ on a RESUME.
+
+Enable APM features
+CONFIG_APM_DO_ENABLE
+ Enable APM features at boot time. From page 36 of the APM BIOS
+ specification: "When disabled, the APM BIOS does not automatically power
+ manage devices, enter the Standby State, enter the Suspend State, or take
+ power saving steps in response to CPU Idle calls." This driver will make
+ CPU Idle calls when Linux is idle (unless this feature is turned off --
+ see below). This should always save battery power, but more complicated
+ APM features will be dependent on your BIOS implementation. You may need
+ to turn this option off if your computer hangs at boot time when using
+ APM support, or if it beeps continuously instead of suspending. Turn
+ this off if you have a NEC UltraLite Versa 33/C or a Toshiba T400CDT.
+ This is off by default since most machines do fine without this feature.
+
+Do CPU IDLE calls
+CONFIG_APM_CPU_IDLE
+ Enable calls to APM CPU Idle/CPU Busy inside the kernel's idle loop. On
+ some machines, this can activate improved power savings, such as a slowed
+ CPU clock rate, when the machine is idle. These idle call is made after
+ the idle loop has run for some length of time (e.g., 333 mS). On some
+ machines, this will cause a hang at boot time or whenever the CPU becomes
+ idle. (On machines with more than one CPU, this option does nothing.)
+
+Black display
+CONFIG_APM_DISPLAY_BLANK
+ Enable console blanking using the APM. Some laptops can use this to turn
+ off the LCD backlight when the VC screen blanker blanks the screen. Note
+ that this is only used by the VC screen blanker, and won't turn off the
+ backlight when using X11.
