[Guide] How to patch DSDT for working battery status

Dell XPS 18 - Is it possible?

I couldn't figure out how to get it to work. So I did a google search and downloaded the other version. I'll just have to remember to save a backup every time.

I did a search for method labels on each line I have to fix. Three of them appear under two different method labels. For instance, BFCP appears under BRCP and BIF2. B0ST appears under BSTS and BRCP, and B0MD appears under BIF0 and BIF3. do I need to do two separate "Into Method Label" lines for those?

I did one line for the first item in my list to patch:

into device label EC0 code_regex B0VL,\s+16, replace_matched begin VL00,8,VL01,8, end;
[\CODE]

so would the second part to that one be:
[CODE]
into method label BV0T code_regex \(\^^\PCI0\.LPCB\EC0\.B0VL, replace_matched begin (B1B2(^^PCI0.LPCB.EC0.VL00, ^^PCI0.LPCB.EC0.VL01), end;
[\CODE]

I looked at the patch you have loaded for the Dell XPS 13 to see how it's written. What I don't understand is where the ^^PCI0.LPCB.EC0.VL00 came from... I interchanged it from the one written... is this what comes from the Compile window?

Yes.

so would the second part to that one be:

into method label BV0T code_regex \(\^^\PCI0\.LPCB\EC0\.B0VL, replace_matched begin (B1B2(^^PCI0.LPCB.EC0.VL00, ^^PCI0.LPCB.EC0.VL01), end;

The code at BVOT (note it is BVOT, not BV0T) that needs changing is:

                    Store (B0VL, Local0)

So the patch would be:

into method label BVOT code_regex \(B0VL, replace_matched begin (B1B2(VL00,VL01), end;

BTW, if you do run into some code that uses the parent-scope-specifier '^' you have to escape both of them. This is because ^ has special meaning in a regex (it means roughly NOT) and we do not want that special meaning, so we have to escape both (\^\^\). Where you wrote '\(\^^\PCI0\.LPCB\EC0\.B0VL' you probably meant '\(\^\^PCI0\.LPCB\.EC0\.B0VL', so pay attention to what you're escaping.

It depends on how the original code was written. If the EC field was referred to by ^^PCI0.LPCB.EC0.B0VL, then you need to include the "path" to the new variables just like the path was included to the old variables.

I couldn't figure out how to get your version of MaciASL to work.

It is the same as any other app. You extract it from the ZIP and double click on MaciASL.app.

Did you have to install the original MaciASL.app first? I extracted everything, but It didn't give me a MaciASL.app file.

You probably downloaded the wrong thing (source code?).

Always be sure to read the README (which identifies the download location for builds). We write READMEs so people will read them.

BTW, I will probably move some of these battery patching messages to the actual battery patch guide/thread, as the discussion may be useful for others.

Noted. I've got a patch written. Haven't tested it out yet. Want to see if anything sticks out to you before I pull the trigger on adding it to my DSDT file. I think I'll wait until you move threads before I post it.

I think I've got all the appropriate messages moved...

OK. With that done, i'm posting the patch that i've got written out from my Dell XPS 18. If you don't see anything that strikes you as odd, I will run the patch through MaciASL and see if I get any resulting errors. Luckily, I've got a backup of the DSDT.aml saved so that if something goes horribly wrong, I can overwrite with the beginning. Once I'm where I can spend a little more time on it, I'll figure out how to install your version of MaciASL. It's still a little confusing...

There are errors, so give it a go and see how many you can fix...
