- "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/> 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.
