lm_sensors no sensors were detected

Hi i have installed lm_sensors to try and adjust when my fan comes on but when i run sensors-detect i get this result

# sensors-detect revision 5729 (2009-06-02 15:51:29 +0200)
# System: Acer, inc. Aspire 6530
# Board: Acer, Inc. Mantasta

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): 
Silicon Integrated Systems SIS5595...                       No
VIA VT82C686 Integrated Sensors...                          No
VIA VT8231 Integrated Sensors...                            No
AMD K8 thermal sensors...                                   No
AMD K10 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): 
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor'...                   Yes
Found unknown chip with ID 0xfc11
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor'...                   No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Fintek'...                       No
Trying family `ITE'...                                      No

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): 
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): 
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): 
Using driver `i2c-piix4' for device 0000:00:14.0: ATI Technologies Inc SB600 SMBus
Module i2c-dev loaded successfully.

Next adapter: SMBus PIIX4 adapter at 8040 (i2c-0)
Do you want to scan it? (YES/no/selectively): 
Client found at address 0x50
Probing for `Analog Devices ADM1033'...                     No
Probing for `Analog Devices ADM1034'...                     No
Probing for `SPD EEPROM'...                                 Yes
    (confidence 8, not a hardware monitoring chip)
Probing for `EDID EEPROM'...                                No
Client found at address 0x51
Probing for `Analog Devices ADM1033'...                     No
Probing for `Analog Devices ADM1034'...                     No
Probing for `SPD EEPROM'...                                 
Yes
    (confidence 8, not a hardware monitoring chip)

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.

i dont know if it doesn't support my hardware or if there is some other problem

Re: lm_sensors no sensors were detected

lm_sensors and my Acer Aspire don't talk to each other either. Fortunately you don't need it. If you haven't already, install acpid. It will get started automatically at boot by dbus. Then take a look at /proc/acpi to see the available sensors. Programs like conky can easily be configured to use these sensors.

Re: lm_sensors no sensors were detected

These are all my sensors in /proc/acpi, i didn't know you could control fan speed using conky

Re: lm_sensors no sensors were detected

no i'm after a way to control when my fan turns on and off not just display the information on my screen, but i'm thinking that it may not be possible on my machine, it must just be controlled by the bios

Re: lm_sensors no sensors were detected

Do you have an interface called 'hwmon' in /sys/class/ ?

I think you've read that, but there some world about fan,hwmon too.

yes that was what i was trying to follow but i can't get past the first step because i can't setup lm_sensors

sorry i some how missed your question, yes there is a hwmon folder with a bunch of sub folders also

Re: lm_sensors no sensors were detected

Okay. Each of these folders, i.e. hwmon0, stands for a fan controller on your mainboard that may control one or several fans. Inside hwmonN, there should be a subfolder called device, which contains several interfaces if your BIOS allows software-side fan control. You can read them with cat and write to them with echo.
Examples:
pwm1_enable shows if software-side fan control is enabled (1) or disabled (0). Changing fan speed won't work if this is disabled. (i.e. cat /sys/class/hwmon0/device/pwm1_enable reports 0 -> disabled; you could enable it with echo 1 > /sys/class/hwmon0/device/pwm1_enable).
pwm1 allows to change fan speed. The values range from 0 (fan off) to 255 (full speed, 12V).
fan1_input shows the current RPM if a fan is connected. You can only read from this interface. Its useful to check all of these in the each of the hwmon folders to find out if there is actually a fan connected to the fan controller (they often have more ports than mainboard manufacturers use).
There might be a fan1_div, this is somehow related to how the kernel reads the RPM, I don't know how it works.
There might be interfaces for different fans in the same hwmon folder, i.e. pwm2_enable, pwm2, fan2_input, etc., all interfaces with the same index belong to the same physical fan connector.

Warning: These interfaces, if they work, control the fans directly without any kind of security measure. If you shut some essential fan down, it will stay off until you reboot your notebook melts down.

(If you see something like in0_alarm, in0_input, in0_max, etc. it's a voltage monitoring chip.)

If one of those interfaces can do something, fan control can work using the fancontrol daemon.
If none of those folders contain a working pwm interface, fan control seems to be unavailable. sad
Sometimes there is an option in the BIOS to enable it, and for some BIOSs software-side fan control only works if dynamic fan control is disabled in the BIOS and fan speed is set to a static value - or vice versa.

Re: lm_sensors no sensors were detected

I think i might be out of luck, i have "/sys/class/hwmon/hwmon0/name  power  subsystem  temp1_crit  temp1_input  uevent"
the contents of "name" reads acpitz,
the contents of "uevent" is empty,
the contents of "temp1_crit" reads 105000,
the contents of "temp1_input" reads 48000 (or whatever the temp happens to be when i open it)
inside /power is a file called "wakeup" which is empty,
inside subsystem  takes me to "/hwmon0/name  power  subsystem  temp1_crit  temp1_input  uevent" and every time i click on /subsystem/hwmon0/ it takes me to "/hwmon0/name  power  subsystem  temp1_crit  temp1_input  uevent" untill i get an error message saying too many levels of symbolic links.

and the bios doesn't have anything regarding fans

Re: lm_sensors no sensors were detected

Hm, on three PCs i know of there are the temps and the pwm1, etc. entries. This doesn't seem to be a configuration or software issue then. I don't have any other idea than googling for your notebook model and lm_sensors left. sad

Re: lm_sensors no sensors were detected

yea i think my bios probably doesn't allow it, i've done alot of googling and there is alot of info on acer aspire one's and some on the 5000 series but i've not found one on the 6530, it's no big deal though the fan comes on at 49c and turns off at 45c its just some times it can sit on 45c for a while brfore it turns off.

thanks for your help
