laptop temperature?

[jcolyn]

In the terminal write the following command

acpi -t

acpi has to be installed first.

sudo apt-get install acpi

acpi has to be installed first.

sudo apt-get install acpi

i do have it installed. i even reinstalled it and still not working

how do i check the temperature on my laptop? comp in sig

The solutions described don't work with all hardware. Although I have installed the software, I always get a reading of 26.8 degrees C, which is absurd.

If you have not already done so install lm-sensors.

sudo apt-get install lm-sensors

Next in a terminal enter

sudo sensors-detect

enter yes (not "y") to each question except for the one that instructs you to hit enter. Close the terminal and reboot the computer.

Once back up in the terminal enter

sensors

note sudo is not needed for this command.. It should then give a readout of all sensors detected..

38 degrees C is normal. Most cpu's should run between 30-40 degrees C when idle and will only increase when a load is put on it..

Normal loads usually won't increase the temp more than 10-15 C..

here is what i got:

# sensors-detect revision 5818 (2010-01-18 17:22:07 +0100)
# System: Hewlett-Packard HP ENVY 14 Notebook PC (laptop)
# Board: Hewlett-Packard 1437

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 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): yes
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor'... Yes
Found unknown chip with ID 0x8502
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor'... No
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
Found unknown SMBus adapter 8086:3b30 at 0000:00:1f.3.
Sorry, no supported PCI bus adapters found.

Sorry, no sensors were detected.
This is relatively common on laptops, where thermal management is
handled by ACPI rather than the OS.

I mis-typed, and have corrected the error: 26.8C/81F. The machine has been running for several days, and the bottom of the case is noticeably above body temperature.

Update: 55 minutes of continuous use later, and the temperature sensor still says 81 °F.

Update: 10 hours later, after sleeping overnight, with the house temperature turned down, it's still reporting 81 °F.

Now I remember why I uninstalled this software after installing it last year.

Hardware: Acer AA1 D150 netbook.

I won't be able to help you since I don't use acpi.

Newer laptop tend to favor acpi over sensors.

[SebSmith]

well then how do i monitor my comp temperature with acpi?

[SebSmith]

nobody uses acpi?
