man apmiser (Administration système) - power-saving daemon for ThinkPads
NAME
apmiser - power-saving daemon for ThinkPads
SYNOPSIS
apmiser [OPTIONS]
DESCRIPTION
apmiser is a power expenditure management daemon for IBM ThinkPad laptop computers.
apmiser periodically checks your CPU utilization. If the machine is using battery power or is charging the battery and apmiser sees that you are using a lot of CPU, it switches the machine into "high" power-expenditure mode for as long as required, then switches back to "auto"matic power-expenditure mode. Some users have found that this yields a better combination of performance and battery longevity than one gets with one of the power expenditure modes on its own.
OPTIONS
- --daemon
- Detach from the controlling tty and run in the background
- --help
- Display information about the options
- --high_threshold=PERCENT
- Set the CPU usage level above which to run at full speed
- --low_threshold=PERCENT
- Set the CPU usage level below which to start saving power
- --syslog
- Send all messages to the syslog facility
- --term=SECONDS
- Set how many seconds later the CPU usage should still matter
- --trendiness=FACTOR
- Set how strongly recent CPU usage should be favored
- --verbose
- Report all power expenditure level changes
- --version

BUGS
apmiser should be written in C and should use libsmapidev instead of tpctl to set the power expenditure level.
