Hello list, Any tips how to debug why laptop CPU temperature is around 30 degrees celsius higher on Fedora 14 or Fedora 15 compared to Windows 7 ? Both Linux and Windows were idle when measuring.. I tried both Fedora 14 (Linux 2.6.35) and Fedora 15 (Linux 2.6.38). Laptop specs: - HP Elitebook 8530p. - CPU: Mobile Intel Core 2 Duo T9600 (Penryn). Results: - Windows: CPU is 57 - 65 celsius when idle. - Fedora/Linux: CPU is 85 - 95 celsius when idle. The laptop definitely feels much more hot when in Linux and sometimes shuts down with thermal overheating warning. That overheating problem never happens in Windows. Checking "powertop" in Linux shows the CPU is mostly running with the lowest MHz available. Not much "idle" time though.. I was using "Core Temp" in Windows and /sys ACPI interface in Linux: # cat /sys/bus/acpi/devices/LNXTHERM\:03/thermal_zone/temp 86000 # cat /sys/bus/acpi/devices/LNXTHERM\:03/path \_TZ_.CPUZ "acpi -t" also shows the same CPU temperature. Fedora 15 Linux 2.6.38 dmesg here: http://pasik.reaktio.net/fedora/f15/cputemp/dmesg-laptop-f15.txt Any ideas how to track what's causing that? All suggestions welcome!
