笔记本先后经历了两次返场维修,第一次,因为主板自动断电,第二次则是因为SSD硬盘插上去认不到。
过了20天左右的时间,笔记本才能正常使用。但是开机感觉风扇的转速一会飞快,一会儿又没有声音,怀疑CPU的风扇有问题。
所以研究了下如何检查CPU的温度:
两种方案:
1. ACPI
显示没有输出,我只能man一下看看。
-
NAME
-
acpi_available - test whether ACPI subsystem is available
-
-
SYNOPSIS
-
acpi_available
-
-
DESCRIPTION
-
acpi_available checks whether the ACPI ("Advanced Configuration and Power Interface") subsystem is available, as evidenced by the presence of the /proc/acpi directory.
-
-
OPTIONS
-
None.
-
-
EXIT STATUS
-
0 (true) ACPI subsystem is available
-
1 (false) ACPI subsystem is not available
看来我需要检查acpi_available的返回值。
-
root@kali:~# acpi_available
-
root@kali:~# echo $?
-
0
继续
-
apt-get install acpi
-
root@kali:~# acpi -t
Thermal 0: active, 90.0 degrees C
Thermal 1: ok, 0.0 degrees C
看到这个温度,我有点懵,这个温度有点过高了。
2. 我决定再使用lm-sensors来确定下:
-
apt-get install lm-sensors
-
sensors-detect
-
一路yes下来,最后看到这个
-
Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `coretemp':
* Chip `Intel digital thermal sensor' (confidence: 9)
To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!
Do you want to add these lines automatically to /etc/modules? (yes/NO)yes
Successful!
Monitoring programs won't work until the needed modules are
loaded. You may want to run '/etc/init.d/kmod start'
to load them.
Unloading i2c-dev... OK
Unloading cpuid... OK
到这里配置完成,使用命令来查看下:
-
root@kali:~# sensors
-
acpitz-virtual-0
-
Adapter: Virtual device
-
temp1: +49.0°C (crit = +105.0°C)
-
temp2: +0.0°C (crit = +105.0°C)
-
-
coretemp-isa-0000
-
Adapter: ISA adapter
-
Package id 0: +47.0°C (high = +105.0°C, crit = +105.0°C)
-
Core 0: +45.0°C (high = +105.0°C, crit = +105.0°C)
-
Core 1: +46.0°C (high = +105.0°C, crit = +105.0°C)
过了段时间,大概1小时后,温度降到了这样。
3. 使用logger 脚本记录10分钟温度的变化。
脚本如下:
-
exec 1> >(logger -s -t $(basename $0)) 2>&1
-
-
i=0
-
while [[ $i -le 20 ]];do
-
sleep 30
-
sensors
-
let i=$i+1
-
done
