I bought a new laptop, a Legion 545. And I have installed Ubuntu 18.04.
The laptop battery time is almost 60 minutes. I have tried to optimize it with powertop and tlp, but the battery discharge rate remains>38 any lead. I may have to go back to Windows - which I don't want to...
The battery reports a discharge rate of 39.5 W
The power consumed was 0.00 J
System baseline power is estimated at 40.5 W
