IBAM – The Intelligent Battery Monitor for Laptops

Sponsored Link
IBAM is an advanced battery monitor for laptops, which uses statistical and adaptive linear methods to provide accurate estimations of minutes of battery left or of the time needed until full recharge. This software relies on either APM, ACPI, SYSFS or PMU kernel support to access the battery status.

IBAM solves this problem by creating a battery and charge profile (as seen on the right for my old laptop) from which it can compute the actual times remaining. The red graph represents the battery cycle (where the laptop is running on battery), the x-axis represents the bios-minutes (now bios-percentage), the y-axis the actual average lengths of that minute (percentage) in seconds. As you can see the bios minute was about 50 seconds long from 200 minutes to 60 minutes, and only 10 seconds long from 40 minutes to 20 minutes. No wonder I was surprised that the battery was empty so soon... ;)
The green graph shows the charge cycle, which seems to be a bit more useful, still the same technique can be used to give the user an idea how long the charge process will need.
As soon you created initial profiles you can get the similar graphs for your computer by using the option "--plot".
Of course the computer will consume more energy on a high load and IBAM does take this into account by determining a linear adaptive method for the current cycle.

Install IBAM in Ubuntu

sudo apt-get install ibam

This will install all the required packages

  1. conky can also be used to indicate battery status
    I use
    ${battery_percent C1BE}% ${battery_bar C1BE}

    note C1BE is my battery, yours may be different, to check use $ls /proc/acpi/battery/

  2. Hi,

    I rewrote the ibamtray to totally mimic gnome-power-manager applet. It even integrates with it’s translations. Upon startup it will try to hide the gnome-power-manager applet, but you’ll need my special patch one. Packages can be found in my ppa:
    ppa:mark-baas123/ibam-applet

    Greetings,

    Mark

  3. Hi I just installed ibam to check my laptops battery and to try to fix the battery care function. But when I ran the ibam command in the terminal it gave me the “no apm data available”
    Any ideas?
