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
