Thread: Cpu temperature

  1. #1

    Default Cpu temperature

    I installed opensuse 11.3 to my laptop.

    Toshiba L505-13w satellite. core i5 2.27 ghz , 4gb ram, 1gb ati display.

    I can't measure cpu temperature. I tried "acpi -t" and sensors but nothing happened.I also tried system information widgets from plasma menu.Still I can't see my cpu temperature. Can anyone help me about this problem? I want to see my cpu temp.

    linux-lqgg:/usr/sbin # sensors-detect
    # sensors-detect revision 5818 (2010-01-18 17:22:07 +0100)
    # System: TOSHIBA Satellite L500 (laptop)
    # Board: TOSHIBA NSWAA

    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): y
    Silicon Integrated Systems SIS5595... No
    VIA VT82C686 Integrated Sensors... No
    VIA VT8231 Integrated Sensors... No
    AMD K8 thermal sensors... No
    AMD Family 10h thermal sensors... No
    AMD Family 11h thermal sensors... No
    Intel Core family thermal sensor... No
    Intel Atom thermal sensor... No
    Intel AMB FB-DIMM thermal sensor... No
    VIA C7 thermal sensor... No
    VIA Nano thermal sensor... 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): y
    Probing for Super-I/O at 0x2e/0x2f

    Trying family `SMSC'... No
    Trying family `VIA/Winbond/Nuvoton/Fintek'... No
    Trying family `ITE'... 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

    Sorry, no sensors were detected.
    This is relatively common on laptops, where thermal management is
    handled by ACPI rather than the OS.
    linux-lqgg:/usr/sbin # acpi -t
    Battery 1: charging, 90%, 00:00:16 until charged
    No support for device type: thermal

    Default Re: Cpu temperature

    You seem to have tried everything I would. I use "acpi -V" as it reports on a bit more.

    Did you check out lm-sensors website for a comment about your processor? Sometimes they have advanced config files for mobos.

    I don't know how frequently new acpi stuff gets picked up. On my notebook, the following gives a temperature:
    Code:
    cat /proc/acpi/thermal_zone/TZ00/temperature
    There is also a sensors config file at /etc/sensors3.conf, so have a look through it.
