Title:
unnecessary fan running after resuming from suspend
Status in linux package in Ubuntu:
Triaged
Bug description:
I put my laptop to sleep. Some time later, I resume from suspend by opening
the lid; the fan immediately runs at full speed and does not stop. This is the
case even when the laptop is not running any heavy tasks. Upon running
"sensors" from the lm-sensors package, one of the temperature sensors reports
this:
acpitz-acpi-0
Adapter: ACPI interface
temp1: +48.0°C
It otherwise reports a temperature in the mid-30s
Putting the laptop back into suspend, waiting a few seconds for the fan to
stop and then opening the lid, thus resuming from suspend, will usually fix the
problem of the fan running, and the incorrect temperature report. Sometimes I
may need to close and open the lid two or three times.
