Subject: [PATCH 0/1] platform/surface: platform_profile: handle fan standby state
Date: Tue, 10 Nov 2026 21:09:15 -0500 [thread overview]
Message-ID: <20261111020916.3557508-1-pm@petermarshall.ca> (raw)
This patch extends the Microsoft Surface platform driver to signal the
system's standby state to the SAM, stopping the fan during PM suspend and
restarting it during resume.
Without this change, the fan continues to run during suspend as if the
system was still powered on, and takes a few minutes to slow down and stop
as the chassis cools.
Tested on a Microsoft Surface Pro 9 running kernel 7.3.0.
