This article among others suggested the following to prolong battery life:

Keep cool. Operate in mid SoC of 20–80%. Prevent ultra-fast charging and high loads (most Li-ion)

The main issue here is trying to keep the battery from becoming unusable prematurely. acpi can give the power information on battery percentage to trigger a script, but I don't want to be constantly plugging and unplugging my laptop. I generally keep my laptop plugged in, but I am looking for a program/script to disable the AC power supply without physically disconnecting the adapter cord, so a script can auto-regulate the charge to keep the battery within the 20-80% range. (Similar questions have been asked for OpenBSD and Ubuntu, although not answered particularly conclusively).

Note: Taking out the battery would solve this without scripting, which works if I am at my primary workstation. However, at my secondary workstation I need to be able to move around. A scripting solution would be for situations where I'm on the go.

Platforms: HP Pavilion dm4 and Acer Aspire 7741G 5877
OS: uname -a on the Pavilion gives Linux crunchbang 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1+deb7u2 x86_64 GNU/Linux

  • I could do this by writing to the EC directly. But that was very machine and bios version dependent. I am searching for an acpi method to do the same. – Zibri Jan 06 '18 at 14:33
