[Guide] How to patch DSDT for working battery status

gsalem said:
Ok,
thanks for the confirmation.
Any ideas on how to debug the kext to see why it is not working? I had this working on my installation, then my motherboard broke down and was replaced, still having the same disk. The DSDT and data I've sent are from the new board. I've reinstalled ACPIBatteryManager kext from your repository, No luck.

Regards

Read post #1, "Problem Reporting".
 
Solved!
I booted in ubuntu, and dumped the acpi/tables, found yet another DSDT.aml, size-wise, from the ones I get via F4 under Clover and before and after repairing the motherboard. I simply too the DSDT.aml and put it in EFI/CLOVER/ACPI/patched, and that's it. I even have brightness slider.
Not sure it is very elegant method, but it works. Probably the repaired board is subtly different from the older one, as another issue that I had seems also solved: With the older board, I had to connect the ethernet cable before loading OSX, otherwise it won't see it. Now it works. Go figure.

Thanks again

DSDT.aml extracted via Clover F4 is the same as the one you get from Linux.
If you were using an old DSDT extracted with different hardware installed (or even different BIOS settings, different BIOS version), then you were making a very common mistake.
You should read post #1 regarding extraction of ACPI files as it relates to BIOS/hardware changes.
 
Hi, Rehabman,
I have finished the battery status patch for Lenovo rescuer 14-ISK/15-ISK.
I read your guide carefully and solved my previous problem.
After fixing the Mutex error, it works like a charm.
I want to add this to your repo.
Please review the code, thank you.

Hi RehabMan,

I'm trying to patch my DSDT so far without success..

I was able to find the following 16 bit Fields:

Code: 
                XX11,   16,  //NOT USED
                B1DC,   16, //4 Times
                B1FV,   16, //4 Times
                B1FC,   16, //6 Times
                XX15,   16, //NOT USED
                B1CR,   16, //3 Times
                B1RC,   16, //3 Times
                B1VT,   16, //NOT USED
                CHGR,   16, //NOT USED





This is my patch:

Code: 
into method label B1B2 remove_entry;
into definitionblock code_regex . insert
begin
Method (B1B2, 2, NotSerialized) { Return(Or(Arg0, ShiftLeft(Arg1, 8))) }\n
end;


into device label H_EC code_regex B1DC,\s+16, replace_matched begin BDC0,8,BDC1,8, end;

into device label H_EC code_regex B1FV,\s+16, replace_matched begin BFV0,8,BFV1,8, end;

into device label H_EC code_regex B1FC,\s+16, replace_matched begin BFC0,8,BFC1,8, end;

into device label H_EC code_regex B1CR,\s+16, replace_matched begin BCR0,8,BCR1,8, end;

into device label H_EC code_regex B1RC,\s+16, replace_matched begin BRC2,8,BRC1,8, end;

into method label GSBI code_regex \(B1DC, replaceall_matched begin (B1B2(BDC0,BDC1), end;
into method label _BIF code_regex \(B1DC, replaceall_matched begin (B1B2(BDC0,BDC1), end;
into method label _BST code_regex B1FV replaceall_matched begin B1B2(BFV0,BFV1) end;
into method label GSBI code_regex \(B1FC, replaceall_matched begin (B1B2(BFC0,BFC1), end;
into method label _BIF code_regex \(B1FC replaceall_matched begin (B1B2(BFC0,BFC1) end;
into method label GSBI code_regex \(B1CR, replaceall_matched begin (B1B2(BCR0,BCR1), end;
into method label _BST code_regex B1CR replaceall_matched begin B1B2(BCR0,BCR1) end;
into method label GSBI code_regex \(B1RC, replaceall_matched begin (B1B2(BRC0,BRC1), end;
into method label _BST code_regex B1RC replaceall_matched begin B1B2(BRC2,BRC1) end;


However, my DSDT is not compiling and I am not able to fix these compiler errors:

EDIT: DSDT is compiling now - I used the wrong version. My Bad. I can now see the Intel SR Real Battery in IOReg, but I cannot see the percentage. I also need to apply the Bugfix for AC / Battery indication - will this fix the issue ?

Hi,

yeah, I was not able to get the DSDT to compile properly - so no DSDT in ACPI/patched. I now have managed to compile it and battery status is working.

I also had to put my battery configuration into the DSDT. I have attached it - maybe you would like to add it to your repo. (The patch is also in my previous post.


Thanks for your Guide!


PS: Could you help me with Backlight control?
