[Guide] How to patch DSDT for working battery status

[RehabMan]

HI Rehabman.
I can not start the battery. The patch does not help. Laptop Lenovo B5070. Please.

No ioreg in your debug zip. Please check your files before upload.

Your kextcache output proves kexts are not installed correctly.
All kexts you need must be installed to the system volume.
Read post #2 of the Clover guide for details:

Sorry not noticed.

Why did you make this change?

From:

            Method (_STA, 0, NotSerialized)  // _STA: Status
            {
                ^^EC0.BSHK ()
                If (ECOK ())
                {
                    If (^^EC0.BOL0)
                    {
                        Sleep (Zero)
                        Return (0x1F)
                    }
                    Else
                    {
                        Sleep (Zero)
                        Return (0x0F)
                    }
                }
                Else
                {
                    Sleep (Zero)
                    Return (0x1F)
                }
            }

To:

            Method (_STA, 0, NotSerialized)  // _STA: Status
            {
                Return (Zero)
            }

This will change disable your ACPI battery object,...

SMCBatteryManager.kext is still using ACPI if that's what you're asking...

Hi RehabMan

First, many thanks for all of your work! This is my third computer for macOS。
Problems arose ,the battery is error detected if booting macOS, so, I have to update BIOS to move out the error message.

So, I'm following your guide to patch DSDT. The menu bar battery percentage not updating if charge or discharge. and the error of battery detected is still pending.

Thanks for your support.

"Problem Reporting" files are incomplete.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.
https://www.tonymacx86.com/threads/faq-read-first-laptop-frequent-questions.164990/
Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something.

Hi Rehabman,

The problem of battery percentage updating is solved.

But the battery will be mark as fake one during reboot or shutdown. Could you please help me to fix this problem?

Thank you!
