my laptop cpu is overheating all the time

hi,
my laptop cpu is overheating all the time
cpupower service failed to start due to configuration.
this is my configuration

# Define CPUs governor
# valid governors: ondemand, performance, powersave, conservative, userspace.
governor='powersave'#ondemand

# Limit frequency range
# Valid suffixes: Hz, kHz (default), MHz, GHz, THz
min_freq="800MHz"
max_freq="2.6GHz"

# Specific frequency to be set.
# Requires userspace governor to be available.
# Do not set governor field if you use this one.
#freq=

# Utilizes cores in one processor package/socket first before processes are 
# scheduled to other processor packages/sockets.
# See man (1) CPUPOWER-SET for additional details.
#mc_scheduler=

# Utilizes thread siblings of one processor core first before processes are
# scheduled to other cores. See man (1) CPUPOWER-SET for additional details.
#smp_scheduler=

#  Sets a register on supported Intel processore which allows software to convey
# its policy for the relative importance of performance versus energy savings to
# the  processor. See man (1) CPUPOWER-SET for additional details.
#perf_bias=

# vim:set ts=2 sw=2 ft=sh et:

output of cpupower frequency-info

analyzing CPU 0:
  driver: intel_pstate
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 0.97 ms.
  hardware limits: 800 MHz - 2.90 GHz
  available cpufreq governors: performance, powersave
  current policy: frequency should be within 800 MHz and 2.90 GHz.
                  The governor "powersave" may decide which speed to use
                  within this range.
  boost state support:
    Supported: yes
    Active: yes
    25500 MHz max turbo 4 active cores
    25500 MHz max turbo 3 active cores
    25500 MHz max turbo 2 active cores
    25500 MHz max turbo 1 active cores

Re: my laptop cpu is overheating all the time

This post is missing a lot of information.
- I might have missed it, but can you list more about the hardware? What processor do you have, physical/virtual cores (looks like 4 cores), etc.?
- Typical temperature/frequency readings when the overheating occurs (you can install lm_sensors). You can get cpu frequency with:

$ cat /sys/devices/system/cpu/cpuN/cpufreq/cpuinfo_cur_freq   # replace N with cpu number to check

- What is the negative outcome of the overheating is (just hot, or is it shutting down?)
- What did you change in the config file from the default?
- What is the output of `systemctl status cpupower.service`?
- Have you run `systemctl enable cpupower.service` or are you simply manually starting with `systemctl start cpupower.service`?
- I haven't used cpupower, but did you see the the note on the Arch wiki that starting at boot will result in a failed service message?

I saw this as I was having a similar issue. Here's the information I provided to help others troubleshoot with me.
