        ---help---
          "Power Management" means that parts of your computer are shut
          off or put into a power conserving "sleep" mode if they are not
          being used.  There are two competing standards for doing this: APM
          and ACPI.  If you want to use either one, say Y here and then also
          to the requisite support below.

          Power Management is most important for battery powered laptop
          computers; if you have a laptop, check out the Linux Laptop home
          page on the WWW at <http://www.linux-on-laptops.com/> or
          Tuxmobil - Linux on Mobile Computers at <http://www.tuxmobil.org/>
          and the Battery Powered Linux mini-HOWTO, available from
          <http://www.tldp.org/docs.html#howto>.

          Note that, even if you say N here, Linux on the x86 architecture
          will issue the hlt instruction if nothing is to be done, thereby
          sending the processor to sleep and saving power.
