Lenovo S400 Compatibility

i rebooted, it failed, it can't boot at all, if i boot to the disk, it just restarts, repeating all over again any solution? it was really about the audio patch

Sounds like you have a bad AppleHDA or bad instructions for creating the HDEF _DSM...

Boot with DSDT=No (and perhaps -x) and see if that gets you back into the system.

Otherwise remove the offending AppleHDA.kext from /S/L/E using OS X installer (go into Terminal).

No, it didn't work what would be the instructions for the terminal?

Depends on what your volume name for your OS X install is:

# remind yourself about what the volume name is...
ls -l /Volumes
# remove bad AppleHDA.kext
rm -r /Volumes/your-volume-name-of-hdd-partition-with-osx/System/Library/Extensions/AppleHDA.kext
touch /Volumes/your-volume-name-of-hdd-partition-with-osx/System/Library/Extensions

I got it to boot again using your code, however, the DSDT patch made the bluetooth unfunctional, i shall remove the patch, but how will i do it? Will i just delete the dsdt.aml in the extra folder?

The patch just adds _DSM to HDEF device. To remove the effects of the patch, remove the _DSM method.

And... I don't think that patch is affecting your bluetooth...

Shall i do this patch again? it shows errors.View attachment dsdtremove_dsm.tiff

You need to remove the second TNOT.

This patch will do it:

into definitionblock code_regex External\s+\(\\TNOT\) remove_matched;

It would fix the first one (TNOT problem is actually a problem in the Intel's decompiler), but there is not enough information to determine what is wrong with the rest.

Post the DSL you have...

BTW, you can also execute a simple patch to remove HDEF._DSM:

into method label _DSM parent_label HDEF remove_entry;

In english, it says, "look for a method named _DSM inside a container (parent) named HDEF and remove it."

What is DSL? i thought you are meaning DSM, attached here is the DSDTView attachment dsdt.aml.zip

The patch didn't work, the same errors appear, here is a detailed error list View attachment dsdtpatchtoremove_DSM.tiff

DSL is a DSDT that has not been compiled (saved as text).

You must use both the TNOT patch *and* the _DSM remove patch.
