[Guide] How to patch DSDT for working battery status

[RehabMan]

You think fresh install will help to find the problem? I did it couple times and I did even clean install and this is still happening anyway Ill back with log here soon

I can't predict the future and it depends on what you're doing in your post-install process.

You should look at system.log.

ill post a log file when battery status will turn off now it's working.

 

[hom1e]

Ok, It don't work right now again here's the log file.

There are no logs related to battery in that system.log.

 

[hom1e]

Yeah, I think it really might be some hardware problem. I will be changing my Wifi soon so when I'll open my laptop I'll check the battery adapter area.

I have followed the steps in order to patch my DSDT and get native battery support with your kext, but when I compile the DSDT with the patches, I get 145 compilation errors

I think that the patch isn't completely wrong, but I can't figure what could cause all this errors

Here is the patch

From the repo: "Samsung Series3" appears to be a match.

It works perfectly, you should add to the patch comments that it's compatible with Samsung NP270E5E

Done.

The patch for Y50-70 (battery_Lenovo-Y50.txt) works correctly on Lenovo B50-70!

My original DSDT (unpatched) is attached
