I think no need for an additional patch. The existing Lenovo Y580 patch seems to be a match.
Please test.

works fine. Thanks

I thought that with this patch my touchpad should be detected but still don't work.

Off-topic.
Open a separate thread.

May be is an existing patch for Dell 5490?

In that case, no EC related patching needed.

My Battery status run's without patching. Only with kext. Rehabman, thanks.

As expected without multi-byte EC fields.

@RehabMan please add an update to the battery_Lenovo-y580.txt patch for Lenovo YOGA 720-15IKB. I tried it out based on the posting here:

Also just curious, what patch is everyone using for the battery for the yoga 720 15 inch? I used rehabman's patch for the Lonovo Y 580. It seems to have worked. Although I have noticed a slightly different battery percentage in windows than OSX.

Attaching original DSDT for confirmation.

HI Rehabman.

Then latest ACPIBatteryManager 20180915 Version have problem with AC adapter detection and always show bettery 100% but cant show AC.
However the ACPIBatteryManager 20171001 Version have no this problem.

I saw your post said some ASUS laptop have this problem and related with FBST but my ONDA laptop BIF have no FBST so i dont know how to deal with the latest ACPIBatteryManager wo make my AC adapter works.

Here are my DSDT and SSDT-BATT works with 20171001.

Thanks.
