Toshiba laptop messages too hgh temperatur and suts down

Hi Experts,
My customer has a Toshiba laptop in a remote location, and he left his laptop on at his office for two weeks without airco.

In this location room temperature without airco inside can easily get to 35 celcious at mid day.

When returning from his trip, my customer has noticed that the Toshiba laptop shuts down on its own unexpectedly and constantly shows message too much heat.

What can I do in this case?

typically the CPU fan need to be replaced or the vent is filled with dust or something.

you can also do it yourself.
As @Muhammad Burhan states, it has to do with the system themperature!
The main cause of overheating is dirt and dust being sucked into the computer by the system fans, which builds up over time, forming a layer on the computer's circuits and heatsinks. Computer chips can become extremely hot with use, and a layer of dust can stop the heat from dissipatching and block airflow over the chip. If the computer crashes or freezes after it has been running for a while, the system temperature in the computer's BIOS should be checked.

Restart your computer as the computer's BIOS can only be accessed during the boot process. This should be done after the computer has been running for at least 30 minutes to give the system time to heat up to operating temperature.

Wait for the message to be displayed telling you to press a key to enter the computer's BIOS. The key to press will be shown in this message and varies depending on the BIOS manufacturer. The most common keys are F1, F2, F12, Delete or Escape.

Select "PC Health," "System Health" or a similar option from the BIOS main menu.

Check the temperature of the CPU, which is usually displayed in both Fahrenheit and Celsius. Most modern CPUs have a maximum temperature of 140 degrees Fahrenheit or more, but with a good heatsink the temperature should ideally be in the range of 68 to 104 degrees Fahrenheit.

Many BIOS instructions incorporate a temperature alarm, alerting you if the system is hotter than a pre-set temperature. This can save the hardware from damage as it enables you to shut down the computer before it gets hot enough to cause damage.
If the computer is overheating, open the case and clean the circuit boards and heatsinks with a can of compressed air. An old toothbrush is also good for removing dust between the vanes on heatsinks.
Also check this video for a demonstration on how to clean.  If you dont have the heatpaste, then dont remove the heatsink from he processor!

Note:  Older systems sometimes do not have the themperature indicator in the bios.

what is the exact message - and when does it appear ?  
you can install speedfan - to monitor the temperatures :

the max temperature the system can have is also a function of the model (cpu type used)
older ones tend to heat much more  than modern ones

and for cleaning a laptop : in general you have to disassemble it completely; but with some models you cna reach the cpu + fan easily by removing bottom covers

You could also consider using a USB fan stand for laptops: Google search―
agreed- you can use many external solutions - but they don't cool the interior
