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

Solution 1:

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

Solution 2:

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

Solution 3:

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:
