hi,
twice in the last week I've been caught out where the laptop was running tuned with 'throughput-performance' profile on the work table, and I walked away, carried on working - and had the battery run flat in just over an hour.
Compare this with tuned running the 'powersave' profile - will usually take the battery through to 3hrs+ - and if i just totally turn down the cpu's in the powersave mode, I can get 5 hrs+ on the x1 carbon gen2 laptop I've got.
So what I am wondering is if there is an easy way to have the tuned-adm reset profiles based on external power source. If I'm at the work table and plugged in, run with throughput-performance mode, and if the external power is disconnected, run in powersave mode ? I've had, admittedly a brief, look and found nothing obvious. Has anyone else run into this before ?
Regards

do not know about 'tuned-adm', i presume you added it, or it is centos 7.x. therefore i can not reply to your questions, other than to ask if you use kde and have looked at what it provides.
with centos 6.7 and kde desktop on my laptop, i use the power control setting provided by;
system settings > advanced > power management
with this, i am able to config settings to handle about all conditions, including 'power save mode' and no external power.
having recently purchased a new 6600 mAH battery, i am curious as to just how long laptop will run 'off mains' before i get a notice and have to recharge. so far, my longest run is around 4 hrs, with time left. i do not recall what % battery icon showed.
selectable settings are;
powersave performance aggressive powersave xtreme powersave presentation
each 'type' also has selection for action to apply.
so, if you are running kde, i will suggest checking out the provided 'power management' control,
