Today something strange (but interesting) happened.

I have a Kabylake-r laptop (Intel 8250u) which always idles at 1.2ghz with pkg power at minimum 1.38.
Today I replaced RealtekRTL8100.kext (from Mieze RealtekRTL8100) with this one : RealtekRTL8100.kext.zip

After rebooting my cpu idles at 1.2ghz (as always) but thit time minimum pkg power is at 0.6!!!
That has a positive impact at both battery consuption and heat producing.

If anyone willing to try just let me know :

1) If the above statement happens to you also , and
2) If ethernet is working , since I only use wifi.

@yoel07 , that's strange.

Try to get your laptop to sleep and check again. Sometimes this happens on mine, too.
Also you don't need ssdt-ec.aml, delete it.

To enable hwp you need to add this :
or just enable PluginType in config.plist:
Code:
<key>SSDT</key>
        <dict>
            <key>Generate</key>
            <dict>
                <key>PluginType</key>
                <false/>
            </dict>
        </dict>
