A problem with the cooling system has been detected


When using your Toshiba laptop, the following error appears:

“Warning: A problem with the cooling system has been detected. Please turn off the computer immediately, and return it for service.”


This can be caused by a legitimate fault with the computer.


Contact the supplier or Toshiba for the computer to be repaired.


  1. No,it isn’t always a legitimate fault. This message can be bogus. Toshiba laptops have a software problem that causes these messages to be generated even though the fan is running and the laptop CPU core temps are less than 45 degrees C. Toshiba won’t own up to the problem – just do a search engine query on Toshiba cooling messages.

    1. It is possible for this to occur as the error is generated by software. However, I would have it still checked out by Toshiba or the supplier to be on the safe side.

  2. Just go to msconfig and disable all toshiba startup apps and restart the PC. It is a crappy Toshiba program that thinks the PC has cooling issues. I did this and ran burn-in on it over night and the PC has been running fine ever since. No cooling issues.

    1. Just did this (after calling Toshiba tech support and PC World KnowHow who told me to take it in for repair). It just didn’t seem like a hardware thing, with no signs of overheating on he health check. And lo and behold, the message has gone away! A software glitch. Thanks drew.

    2. This was driving me crazy! I was about to spend some money to have this message removed but just tried your suggestion. Message now gone. Thanks Drew.

    3. Great info Drew!! thanks a million!! some of those start-up apps seem to help my pc run better tho, so I narrowed it down. the specific start-up app that was causin my woe’s was called TCrdMain Application. it has 2 sub listings. I jus disabled those 2 and I was all good. Might not work for everyone but for anyone usin a Toshiba Satellite p855, you should be golden.

  3. For my wife’s computer P75-A7200 Satellite, a continuing problem with this “Warning A problem with your cooling system has been detected” and the computer fan RPM would increase and sometimes the computer would Shut Down. Well after trying everything from flashing the BIOS to reformatting and setting up the computer I finally found that the Function Key Driver: Toshiba Function Key, Windows 8.1
    Posted Date: 2013-10-01 | Version: 1.1.0002.01 | Size: 40.47M
    This Driver enables you to use the function keyboard keys for Volume and Brightness, WIFI ect.
    Well it turns out that this driver somehow conflicts with the CPU fan and doesn’t allow the fan to increase its RPM and air flow per CPU load. As soon as this driver is removed the CPU fan will function normally. No more errors. I Hope this will someone else with this error or Toshiba will make a

  4. Cooling system is detected meaning your laptop is over heated. This is specially occurs when the cooling fan is running slow or stop running. Cooling system issue is a fan issue mostly.
