--- Comment #18 from antony.gelberg@gmail.com ---
Apologies for the "spam". I noticed I have a `sensors` output before and after
the issue, and there are some other differences.

1. GPU went from reporting a temperature to N/A.
2. ucsi_source_psy_USBC000:002-isa-0000 went from reporting a voltage to zero.

Could this be related? Could it indicate a more widespread failure e.g.
motherboard fault than "just" the fan? Where would be a good place to get
further community insight before shipping it off for repair and waiting for the
possible "there is no hardware fault"?
