Disable auto switching between battery and AC in TLP

Hello,

Is there any way to disable this? I have a smaller power supply that does not work well in the performance mode, TLP keeps switching to performance while charging.

Re: Disable auto switching between battery and AC in TLP

You can easily customize what setting is applied in each mode by editing /etc/defaut/tlp configuration file.
CPU performance policy is set with:

ENERGY_PERF_POLICY_ON_AC=performance
ENERGY_PERF_POLICY_ON_BAT=powersave

You can also force a mode with command line and thus ignore the actual power source.

sudo tlp bat
or
sudo tlp ac

This can be used as a udev rule for instance and run a script when the AC adapter is plugged.
To do so, add this to /etc/udev/rules.d/powersave.rules

SUBSYSTEM=="power_supply", ATTR{online}=="1", RUN+="/path/to/your/script"

And create a script file to run:

#! /bin/bash                                                                                   
tlp bat
