How to patch DSDT for working battery status

I have tried it on a few dsdt's no errors

into method label B1B2 remove_entry;
into definitionblock code_regex . insert
begin
Method (B1B2, 2, NotSerialized) { Return(Or(Arg0, ShiftLeft(Arg1, 8))) }\n
end;# 16-bit registers
into device label EC0 code_regex CAP0,\s+16 replace_matched begin AP00,8,AP01,8 end;
into device label EC0 code_regex VOT0,\s+16 replace_matched begin OT00,8,OT01,8 end;
into device label EC0 code_regex CRT0,\s+16 replace_matched begin RT00,8,RT01,8 end;
into device label EC0 code_regex FCP0,\s+16 replace_matched begin CP00,8,CP01,8 end;
into device label EC0 code_regex DCP0,\s+16 replace_matched begin DP00,8,DP01,8 end;
into device label EC0 code_regex DVT0,\s+16 replace_matched begin VT00,8,VT01,8 end;
into device label EC0 code_regex BSN0,\s+16 replace_matched begin SN00,8,SN01,8 end;
# fix 16-bit methods
into method label _BST code_regex \(\^\^PCI0\.LPCB\.EC0\.CAP0, replaceall_matched begin (B1B2(^^PCI0.LPCB.EC0.AP00,^^PCI0.LPCB.EC0.AP01), end;
into method label _BST code_regex \(\^\^PCI0\.LPCB\.EC0\.VOT0, replaceall_matched begin (B1B2(^^PCI0.LPCB.EC0.OT00,^^PCI0.LPCB.EC0.OT01), end;
into method label _BST code_regex \(\^\^PCI0\.LPCB\.EC0\.CRT0, replaceall_matched begin (B1B2(^^PCI0.LPCB.EC0.RT00,^^PCI0.LPCB.EC0.RT01), end;
into method label _BIF code_regex \(\^\^PCI0\.LPCB\.EC0\.DCP0, replace_matched begin (B1B2(^^PCI0.LPCB.EC0.DP00,^^PCI0.LPCB.EC0.DP01), end;
into method label _BIF code_regex \(\^\^PCI0\.LPCB\.EC0\.FCP0, replaceall_matched begin (B1B2(^^PCI0.LPCB.EC0.CP00,^^PCI0.LPCB.EC0.CP01), end;
into method label _BIF code_regex \(\^\^PCI0\.LPCB\.EC0\.DVT0, replaceall_matched begin (B1B2(^^PCI0.LPCB.EC0.VT00,^^PCI0.LPCB.EC0.VT01), end;

You are indeed the man...

I will add it to the repo, with this additional patch:

# fix an error in this DSDT
into method label _DSM parent_label PEGP code_regex Arg0\n.*Arg1\n.*Arg2\n.*Arg3\n remove_matched;

This is a Dell XPS 1502x?

A Dell XPS L502x

I hope others can use it. I could not have done it without your help.

Thanks a million RehabMan,

patch for HP-DV7-1120 here:


Edit: Just remembered a while ago I changed my LPC Device name to LPCB and EC0 to EC, I added patch for the laptops with original DSDT

Great, I'll add the one for original DSDT to the repo.

How to patch DSDT for working battery status ASUS K50ID

Hi I wonder if you can help. I have an ASUS K50ID all working 10.9 except battery. I don't want to use a rollback kext so I have patched my DSDT using the nearest match on your repo which is ASUS-N55SL.txt the values all matched up and the DSDT compiles but I just have an X in the battery symbol. I'm using your driver kext, I think think I've missed some fields if you could take a look and advise what fields I've missed. Thank you

DSDT attached

The ASUS 55SL patch is not a good match. Dell XPS 18 is closer, but you will still need to modify it. Follow the instructions in post #1 and use the Dell patch as a start.

Hi thanks, I have 4 embedded control sections, do the SMB sections need fixing or just ECOR

Read post #1. Any fields within an EmbeddedControl that are multi-byte need to be looked at.

How to patch DSDT for working battery status

Hi RehabMan, You ARE A GOD, THANX!!! With your help and wonderful description I wrote my first DSDT patch ... It works, battery status appeared next to volume indicator immediately after permission repair for ACPIBatteryManager.kext and reboot! My notebook is Samsung R528 DT02EE. Here are my patch & DSDT files:
View attachment Samsung_R528-DT02EE-battery-patch.txt
View attachment dsdt_original.dsl.zip

Here is a little offtopic, I have CMOS reset after every restart and don't know how to deal with it Maybe you can check DSDT, because I made RTC and TIMR patch manually deleted "IRQNoFlags () {}" lines inside those methods. If you know answer please write me in private.

Thank You!

Great... I will add it to the laptop repo (with credit, of course...)

You need to patch AppleRTC. There is an option to do this in Multibeast.
