No battery status on Acer Aspire 7

[krasmaks]

Yes, I tested it on Windows 11 and Xubuntu Minimal (live USB), and battery status works correctly out of the box on both systems without any issues

Hello, is there anything new about the battery status?

 

[krasmaks]

Just to double check, does the battery meter is functional on Windows/Linux?

Hello, it was a while (again). Can I hear something about the issue?

Great.

Yes, backup your data. Do a fresh install. Make sure to erase the whole drive. Also, attach your EFI to check and attach BIOS pictures.

Hello, I did a fresh Sequoia install and erased whole SSD. I recreated EFI, just in case something was wrong in the previous version. Did not see any visible difference in terms of how the system works. The thread issue (battery status), as well as the others (sleep doesn't work, the screen stays black if automatically turned off by system and won't recover until reboot, shutdown doesn't fully turn the laptop off, just black screen and loud fans until force shutdown (restart works without noticeable issues)) are present as before. Here's the link to recreated EFI: https://drive.google.com/file/d/18pDtZ89X_xSlPehLjgLsBhB0cG8tIJeB/view?usp=sharing and here are BIOS screenshots (I didn't attach Boot section because there are only turned off Secure Boot and Boot Order setting and Exit because is only has a few generic save options and no actual settings. Also, Storage Device Configuration in Advanced only has an option to turn off internal SSD, so nothing related. BIOS is up to date):

Does this Laptop has Dual battery?

Add EC Enabler and then check.

The battery is not dual. I added EC Enabler and (with NVRAM reset) nothing changed. It's expected, because in DSDT my battery has only 2 fields, and both are 8 bits (1 byte), so EC Enabler is useless. It looks like the problem is SMC Battery Manager or SSDTs (built with SSDTTime according to Chefkiss AMD Guide)

Try the official SSDTs and downgrade the SMCBatteryManager.kext or try Rehabman's battery kext.

What do you mean by official SSDTs? There are prebuild SSDTs on Dortania guide mainly for Intel, and my CPU is Ryzen 5 5500U. There is only SSDT-EC-USBX mentioned in the guide for AMD (15h/16h), and I already have EC and USBX as different kexts built using SSDTTime. As far as I know USBX on AMD should be specific, and Chefkiss guide doesn't mention any prebuild SSDTs. Please inform me if I still need to try official SSDTs considering all of this, and if so, which exact ones and from where?

As for battery kext, I tried version 1.3.3 of SMCBatteryManager, which seems to be the earliest one officially supporting Sequoia, with VirtualSMC of its version (1.3.3) and with the last one (1.3.6), but it didn't seem to do anything. Then I tried ACPIBatteryManager (the last version available on Rehabman's Google Code Archive of 2013 year; both BitBucket and official GitHub page doesn't seem to have ACPIBatteryManager.kext file itself, even though it may be newer by version) instead of SMCBatteryManager, and after NVRAM reset and restart it unexpectedly just showed the right (as far as I can guess, cannot tell for sure because MacOS currently spans the whole SSD, no space for Windows to see true percentage) battery state: "currently charging" icon disappeared (before it always displayed independently of actual battery state) and the percentage of 54 appeared (it was always 100). Then I logged in and after about 5 seconds I heard "charger just plugged in" sound and the battery state returned to its original state: lightning icon and 100%. Then after waiting for a bit to see if anything changes, I performed a regular restart (without NVRAM reset), and the same thing happened: seemingly right battery state for first 5-10 seconds, and then back to original state. After that I resetted NVRAM and rebooted once again, but this time the state was wrong right from the start. I restarted for the last time of this test (with NVRAM resetting), and battery did not show right percentage and icon. During this testing I never plugged in charger. So, what can it be? SMCBatteryManager doesn't seem to work at all, and ACPIBatteryManager worked for a bit, but then stopped
