# apmiser(8)

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**

  Report the version number of the apmiser program\

## BUGS

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