Did you also implement the second part of the the patch as well?

I don't know what is second part of the patch.

I don't know what is second part of the patch

its in the link you provided by the OP

[Wizzard]

I really dont know what you mean. I just changed the string "Ones" by "7200" in "Name (BPKG, Package (0x0D)" function as in that provided link and I can see the battery status, although not very exact.

Looks to me, that is not the only change made by the OP. See screenshot

Yes, I noticed later, you are right. I may try that change too, but I think more important is that "7200" or another number.

For the sake of sharing, I just read up on this interesting ACPI method. The information is definitely usable in this case.

[ref]Wizzard[/ref], for sake of troubleshooting, try this and report back.

It works, but still it shows the percentage higher than in Linux (approx. 95 percent against 90 percent) so maybe it still needs another tweaking.

[onemanosx]

Does percentage decrease or increase with use?

instructions on whether I can convert the DSDT itself for operation SSDT-BAT please, please give me the whole information

[Wizzard]

Does percentage decrease or increase with use?

 

Decrease, of course The percentage is always 3-5 percent higher than in Linux.

[onemanosx]

Decrease, of course The percentage is always 3-5 percent higher than in Linux.

The difference between OS is commendable, I think. You may try and input your custom _BIF as per the documentation (https://github.com/gsly/OS-X-ACPI-Battery-Driver/wiki/_BIF-Method), if you are up for it.

Anyway, appreciate if you can test this DSDT and see if battery status works. Thanks in advance.

Yes, works, but still showing percentage a few percent higher than Linux/Windows.

Thank you for testing. This DSDT proves that battery capacity patch is not required. Appreciate your feedback.

I wont worry abt the few % off linux/windows.

[Wizzard]

Thank you very much for your help effort. I think I can live with that
