[Guide] Laptop Battery Indicator - The DSDT Patching Horror

[onemanosx]

[ref]Wizzard[/ref], Sorry, cant help further.Try to google for solutions. Anyway, is your trackpad working? Never seen some of those weird kexts you had for i2C device.

[Wizzard]

Okay, thank you anyway. Nope, trackpad does not work. Why weird kexts?

do custom patch if there is no lenovo g570.

Upload your dsdt.aml

Why weird kexts?

No idea what VoodooI2CAtmelMXT.kext does. You should read I2C documentation and determine if your device is Elan, FTE, HID or Synaptics - https://github.com/alexandred/VoodooI2C

Try my last attempt for your working battery

I dont remember where I got all those kexts, I think I was recommended it on some forum and so downloaded it

I think my touchpad should be SYNA3602, according to some gyus having the same or similar notebook. So I deleted all the Voodoo kexts except Synaptics, but still not working. I think that this touchpad is very unsupported still.

Thank you very much for another DSDT, but it still shows 0 percent. I must try to patch it myself. I just get the errors like "Capacity read zero" in dmesg.

[onemanosx]

dmesg

you can try using other versions of acpibattery kexts. Gd luck.

[Wizzard]

Do you think that older version of ACPI BatteryManager would be better?

[Wizzard]

Okay, I think I found a part of the solution on a competitive forum and it looks like this:

 

Name (BPKG, Package (0x0D)
                   {
                       Zero, 
                       Ones, 
                       Ones, 
                       One, 
                       0x2710, // this is what I have to edit, original was "Ones", I replaced it by 7200, 5000 or 1000
                       Zero, 
                       Zero, 
                       0x64, 
                       Zero, 
                       "SR Real Battery", 
                       "OneManOSX", 
                       "Real", 
                       "Intel SR 1"
                   })

 

So now I can see non-zero percentage of battery! Just the percentage is higher than the one in Linux and Windows. So maybe I should find the right number (I dont know how to find it out yet). My battery has the capacity of 5000 mAh, so I would guess that number would be 5000, but I dont know.

edit: and also the percentage in a status bar does not change as the battery discharges.

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

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

[onemanosx]

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.

[onemanosx]

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.

[Wizzard]

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?

[ford2201]

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.
