+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.
