Hi! Long ago I puzzle how to make that showed the battery. If I set ACPIBatteryManager.kext RehabMan from 2016-0628, the icon of the battery appears, but from 0% and doesn't work. + after installation of kext brightness control on the keypad disappears (probably it is got not completely since the icon on the screen in case of regulation doesn't appear). I tried different patches RehabMan-and, I tried to apply what found here on forum branches - nothing turned out. Correct please my DSDT.aml or help council that in it to change. Thanks!
(In Backup DSDT F4 Clover archive and mine which I use)
P.S. the icon reacts to taking out or connection of charging and 0 to 2%.

The patch for "Lenovo Y570" appears to be a match for your DSDT.

Thanks! You the wizard) I made new dsdt from scratch (Clover F4+MaciASL+patch), I applied Lenovo Y570 patch. The battery started working!!! This patch work on Lenovo Y550.
Only the battery dies quickly, I think big energy consumption by the processor. Or my battery already bad...

Mr. Rehabman, please help me to checking what is wrong with my dsdt patching for battery status... I am following your guide from the first post, I am convert any 16 bit into 8 bit, breaking into low and high...after compile and put dsdt into extra folder (i am using enoch boot loader)..my battery status is show up...charging and discharging detection work correctly, but the percentage not working normally (some time jumping into 100% or stuck 99% while charging and when discharging the percentage is not decrease correctly, remaining time shown 0:00)

Behaviour percentage while charging is from 0% jump to 20% jump to 40%, (add 20% everytime update), while discharging 100% down to 80%...(minus 20% everytime update)..so weird..:crazy:

On the system Information..at power section..another miss behave is Full Charge Capacity (mAh) = 5

With this kind of problem, i don't know with part of dsdt i have to look up to make another correction...please your guidance , tx before

attach original dsdt,patch dsdt and ioreg
