Ok I found several declaration with non-zero value (mostly 0x07).. But if the battery status is working expectedly should I be worry about it?

Thanks.

Thanks.

I would apply it since there could be other DSDT functions that are failing... It is a "no brainer."

I installed ACPIBatteryManager.kext and restarted once the system powered back up I saw the battery icon in the status bar with a black X through it. Any ideas?

Likely DSDT not correctly patched.
