Hi Rehabman,
Reporting back after completing some tests.
After installing the PS2 debug version, battery status is not showing at 10.10.5
When looking at console log, latest logs(10.10.5) seems to be the same compared to 10.10.4. But in 10.10.4 battery status is displaying and PS2 keyboard is working.
I even removed the PS2 kext, then rebuild and reboot. At login screen, the battery is just waving 'hello', just have use a usb kb (to login).
Then after that, I upgraded fakeSMC from 1372 to 1394, reboot, still battery status is not displaying.
I will patch my DSDT again and see if I missed something.
Attach is my log(s). I used the same DSDT for 10.4 and 10.5. Can you tell why? Does this mean, ALPS is broken at 10.5?
