Power Management / Tuned Following External Power Source

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
