How to check the battery temperature of laptop? How do I know the normal temperature of it?

Question

How to check battery temperature? How do I know the normal temperature of it?

My OS is Ubuntu, and my laptop is Lenovo G470.

Output of acpi -t:

Thermal 0: ok, 0.0 degrees C

That's a lightly odd question, that seems to have nothing apparent to do with Ubuntu. Anyway, to find out the temperature, use a thermometer, and to find its normal temperature, search for documentation, or contact the manufacturer. — mikewhatever, Nov 01 '13 at 13:42
@mikewhatever: Thanks for your comment. I would like to know if there is any app / software or indicator for Ubuntu to find out the temperature. I think there is. — pablofiumara, Nov 01 '13 at 13:44
@mikewhatever: I have already seen some apps related to the hardware. — pablofiumara, Nov 02 '13 at 01:01
@guntbert: thanks for your comment. This is the output I see of that command: No such file or directory — pablofiumara, Nov 02 '13 at 01:01
...and can you post links of those that could monitor battery temperatures. — mikewhatever, Nov 02 '13 at 07:21

acpi is used to monitor battery information. Try acpi -t for thermal information. Also check out man acpi for other options.

Thanks for your answer. Unfortunately, acpi tells me this which I do not think is correct: "Thermal 0: ok, 0.0 degrees C". Am I right? – pablofiumara Nov 01 '13 at 13:43
Can you pot your output of acpi -t. – mikewhatever Nov 01 '13 at 13:43
pablofiumara@pablofiumara-Lenovo-G470:~$ acpi -t Thermal 0: ok, 0.0 degrees C – pablofiumara Nov 01 '13 at 13:45

There are many ways to check out the battery temperature of your laptop.

The information regarding your battery status and acpi is stored in /proc and /sys file system. The easiest way to read this information is using the following commands:

upower a command line tool for UPower which provides an interface to enumerate power sources on the system and control system-wide power management.

acpi command shows battery status and other ACPI information from /proc and /sys file system.

1- Use upower command to check battery status

Type the following command :

$ upower -i /org/freedesktop/UPower/devices/battery_BAT0

Sample outputs:

native-path:          /sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0A:00/power_supply/BAT0
vendor:               Samsung SDI
model:                DELL 1C75X35
serial:               1820
power supply:         yes

  present:             yes
  rechargeable:        yes
  state:               fully-charged
  energy:              98.235 Wh
  energy-empty:        0 Wh
  energy-full:         98.235 Wh
  energy-full-design:  98.235 Wh
  energy-rate:         0.0111 W
  voltage:             12.864 V
  percentage:          100%
  capacity:            100%
  technology:          lithium-ion

2- Use apci command to check battery status using terminal:

The acpi command may not be installed by default so use apt-get command or yum command to install the same:

$ sudo yum install

OR

$ sudo apt-get install acpitool

Linux check battery command

Type the following command:

$ acpi -V

Sample outputs:

Battery 0: Full, 100%
Battery 0: design capacity 8400 mAh, last full capacity 8044 mAh = 95%
Adapter 0: on-line
Thermal 0: ok, 53.5 degrees C
Thermal 0: trip point 0 switches to mode critical at temperature 107.0 degrees C
Cooling 0: LCD 0 of 15
Cooling 1: Processor 0 of 10
Cooling 2: Processor 0 of 10
Cooling 3: Processor 0 of 10
Cooling 4: Processor 0 of 10
Cooling 5: Processor 0 of 10
Cooling 6: Processor 0 of 10
Cooling 7: Processor 0 of 10

To just see status, enter:

$ acpi

Sample outputs:

Battery 0: Charging, 17%, 01:20:06 until charged

See ac adapter information:

$ acpi -a

Sample outputs:

Adapter 0: on-line

Show thermal information:

$ acpi -t

Sample outputs:

Thermal 0: ok, 39.5 degrees C

To use fahrenheit as the temperature unit:

$ acpi -tf

To use kelvin as the temperature unit:

$ acpi -tk

Try the program psensor. You can get it by typing sudo apt-get install psensor. It places all the temperature sensors available to it in a nice compact GUI, graph, and toolbar icon. Here's a screenshot: enter image description here

Very nice, like it :D – Tim May 23 '15 at 08:58
No problem. Just cross reference, a lot of the time it can misname sensors. Usually it gets them all. Maybe not for you as my computer is custom built. :) – waterlubber May 23 '15 at 13:45
Yeah, self build too. It seems to see some that are non existent (0 rpm), but this is neat – Tim May 23 '15 at 13:45

The package lm-sensors contains a very useful tool:

The command sensors-detect tries to find any sensors it knows of, and any other it can recognize.
It does this by various kinds of heuristics, tests, and, if you agree, crude tricks.

The result is saved as a configuration file for the command sensors, which can be used to list the sensors that were found, and read the actual values.
