- tristate "Advanced Power Management Emulation"
- ---help---
- APM is a BIOS specification for saving power using several different
- techniques. This is mostly useful for battery powered laptops with
- APM compliant BIOSes. If you say Y here, the system time will be
- reset after a RESUME operation, the /proc/apm device will provide
- battery status information, and user-space programs will receive
- notification of APM "events" (e.g. battery status change).
-
- In order to use APM, you will need supporting software. For location
- and more information, read <file:Documentation/pm.txt> and the
- Battery Powered Linux mini-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>.
-
- This driver does not spin down disk drives (see the hdparm(8)
- manpage ("man 8 hdparm") for that), and it doesn't turn off
- VESA-compliant "green" monitors.
-
- Generally, if you don't have a battery in your machine, there isn't
- much point in using this driver and you should say N. If you get
- random kernel OOPSes or reboots that don't seem to be related to
- anything, try disabling/enabling this option (or disabling/enabling
- APM in your BIOS).
