Hi.

Macbook Air 2017 A1932 820-01521-A. No liquid damage. Powers on ok. Performance is sluggish and fans initially spin slow but get faster and louder after 2-3 minutes.
Apple diagnostics reports:
1) battery requires service: PPT006
2) There may be an issue with SMC: PFM006

Does this SMC need to be replaced?
Have you seen this before?

01521 has SMC embbeded into T2.
Is the battery detected by macOS?

The fan of this machine runs to max speed without battery.
You should try known good battery.

I can try a good battery, just don't have one right now.
The laptop is so slow it takes 30 minutes to login and for everything to load.
Would a bad battery do that?

 

[2informaticos]

Yes, is possible...

I replaced the battery and it has fixed the issue.
Thank you for the guidance... much appreciated!
