Description pgaltieri 2013-12-11 15:02:42 UTC 
Description of problem:
When I run mate-sensors-applet it shows the following sensors listed under libsensors:

  temp1
  Physical id 0
  Core 0
  Core 1
  temp1

If I go look in

/sys/devices/virtual/thermal

I see

cooling_device0  cooling_device2  cooling_device4  thermal_zone1
cooling_device1  cooling_device3  thermal_zone0

and if I run

cat /sys/devices/virtual/thermal/cooling_device0/type

for cooling_device[0-3] it shows the type as Processor.

gkrellm also shows 4 processors.

Version-Release number of selected component (if applicable):
mate-sensors-applet.x86_64             1.6.0-3.fc19

How reproducible:
Always

Steps to Reproduce:
1. Start mate-sensors-applet
2. See how many cores it shows
3.

Actual results:
Only 2 are shown

Expected results:
All 4 are shown

Here with my old intel core to quad it works out of box.
I forward your issue to upstream. Pls ask there for help.

Comment 2 Wolfgang Ulbrich 2013-12-26 14:34:47 UTC 
The Core i7-4500U only has 2 physical cores so this is correct. http://ark.intel.com/products/75460
