I think newer hardware started using some other method than the embedded controller we rely on. Battery status reports require correct locking with embedded controller, and that probably don't work. I assume you see cpu spiking on some acpi thread.

Replying to tqh:

I assume you see cpu spiking on some acpi thread.

The only acpi thread I see is acpi_task and it seems to be idle all the time.
