sensors-detect not detecting sensors on my dell laptop (XPS L401X)
 
Hi,

I am using Red Hat Linux on my Dell XPS Laptop. I am running sensors-detect on my laptop but it is not detecting sesors. I am using SpeedFan software in windows which detects sensors and shows CPU,HDD temperatures. Please help me out to configure lm_sensors.
Code:

[root@desktop ~]# sensors-detect
# sensors-detect revision 1.1
# System: Dell Inc. XPS L401X
# Board: Dell Inc. 01PNG7

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): YES
Silicon Integrated Systems SIS5595...                      No
VIA VT82C686 Integrated Sensors...                          No
VIA VT8231 Integrated Sensors...                            No
AMD K8 thermal sensors...                                  No
AMD Family 11h thermal sensors...                          No
Intel Core family thermal sensor...                        No
Intel AMB FB-DIMM thermal sensor...                        No
VIA C7 thermal and voltage sensors...                      No

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): YES
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor'...                  No
Trying family `SMSC'...                                    No
Trying family `VIA/Winbond/Nuvoton/Fintek'...              No
Trying family `ITE'...                                      No
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor'...                  Yes
Found unknown chip with ID 0x8502

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): YES
Probing for `IPMI BMC KCS' at 0xca0...                      No
Probing for `IPMI BMC SMIC' at 0xca8...                    No

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): YES
Probing for `National Semiconductor LM78' at 0x290...      No
Probing for `National Semiconductor LM79' at 0x290...      No
Probing for `Winbond W83781D' at 0x290...                  No
Probing for `Winbond W83782D' at 0x290...                  No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): YES
Found unknown SMBus adapter 8086:3b30 at 0000:00:1f.3.
Sorry, no supported PCI bus adapters found.

Sorry, no sensors were detected.
Either your system has no sensors, or they are not supported, or
they are connected to an I2C or SMBus adapter that is not
supported. If you find out what chips are on your board, check
http://www.lm-sensors.org/wiki/Devices for driver status.
[root@desktop ~]# sensors
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

Hi themande,

the appropriate kernel-modules have to be loaded before the system can recognize the sensors.
Please post the output of
Code:

uname -a
and
Code:

lsmod | sort
