No battery status on Acer Aspire 7

krasmaks · Apr 29, 2025

I've heard about Mutex patches, but where do I get it from or how do I make one? Most of them I saw in MaciASL patch interface were for pretty old Intel laptops, which is not the case, and were made by Rehabman, who is absent in the community for a long time. As for the pictures, here they are, hopefully they will be useful:

Here's an update: I did a little research and tried patching Mutex Fix from MaciASL Rehabman section, but it didn't seem to do anything, including battery indicator (it still always shows 100% and currently charging status). I saved the file after patching as "DSDT.aml", included it in config.plist and moved to the top, if it means anything. Please tell where I can get more fresh and matching for my system Mutex Fix, if that's the case. As always, thanks for your help!

Attach a copy of bootlog, IOReg, System Report and EFI.

I'm not sure if did everything correctly, but here are the files. Thank you very much!

UPD: these logs were made without test DSDT.aml, because I thought it could interfere debugging. Please inform me if it was actually necessary! Also, OC folder I forgot to attach

That's not how you get bootlog. The correct command is:

Code:

log show --last boot | head -1500 > ~/Documents/bootlog.txt

Also, your EFI is not as per the guide. Here are a few issues. Make the following changes to your config.plist:

- ACPI sorting order is not correct. ALS0 should load first, then PNLF and before ALS0, PLUG-ALT.
- Disable FadtEnableReset and ResetLogoStatus Quirk
- FixupAppleEfiImages shouldn't be required for your hardware.
- Kexts loading order is not correct. Mandatory kexts should load first.
- Remove -vsmcdbg from boot args.

Once you're done with the changes, save your config.plist. Restart the system and reset NVRAM twice. Attach the new PR files.

I'm not sure if I made kexts load in the right order, but the rest is done (including NVRAM resets). Here's the files. I appreciate your help!

Hello, it's been a few days, may I know if there is some progress about battery status or if I should attach other files?

Can you mention what macOS version are you running?

krasmaks · May 13, 2025

Sure, it's MacOS Sonoma 14.7.5

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