How to patch DSDT for working battery status

Hi RehabMan,

Following your first post and going through all the post inside this topic, I manage to complete the patch (inside the attachment).
But still I can't get any reading from the Battery Status (0%)..
Can you help me please? Any other info you required please just let me know.

Yes, I noticed one patch from your repo (Lenovo X220) which is quite similar to mine but not exactly the same. So I decided to start from the scratch.

Thank you very much.

Edit: Just for additional information, FYI I'm booting from MBR using Chameleon v2.2svn r2378.. I've included my IOreg, Chameleon Boot setting, & smbios.plist for your convenient. Thanks..

Update: Applied the nonzero mutex fix and AC Adapter fix but still no luck :(
I've attach latest ioreg & DSDT after applying these patch too (after_fix_nonzero_mutex.zip)..

ioreg files are corrupt. No DSDT was provided.

look that battery health app shows all parameters ok but battery status indicator is colored red and shows remaining time 0:03 and tells me that mac will power off if i don't charge my battery

here is my dsdt.asl

Amperage is a very large negative number. Run the debug version so you can see the values coming back from _BST. Then review the code there. You can use ACPIDebug to debug your DSDT methods.

I've already apply the patch(for 16-bit,32-bit & 128-bit).. Can you point which part i didn't patch yet based from the DSDT i;ve uploaded previously? Here is some screenshot

Is it possible that the DSDT is not loaded?
Ive verify from bdmesg the file size is the same with the one from /Extra..

Thank you

Just the first few examples that I found. There are more.

Code: 
                ECRC,   16, 
                ECAC,   16, 
                ECVO,   16,
