powertop does not accurately determine battery discharge rate on HP zBook Studio G5

[Nils Kaiser]

If i run powertop it reports the following information (same as #1813496).

The battery reports a discharge rate of 393 mW
The power consumed was 7.90 J
The estimated remaining time is 174 hours, 30 minutes

Summary: 2031.2 wakeups/second, 0.0 GPU ops/seconds, 0.0 VFS ops/sec and 34.4% CPU use
