Steps to Fix Overheating, Random Shutdown and Thermal issue on Dell Laptop

Overview: We have come across situations where laptop overheats and because of the overheating, the system shuts down randomly and freezes quite often. Today in this article we will troubleshoot overheating issue on Dell PC.

Let’s Start with Few Practical Scenarios

Scenario 1: Dell 5570 Overheat Problem & Battery Wear Problem

Dear Dell Support Team……. hi I purchased Dell 5570 Core i7 ram 8 with a AMD Radeon 530 4gb GDDR5 Two months ago The first problem:- the notebook reached 99°C according to Open Hardware Monitor during games with use the cooling base The second problem:- battery wear is 21% after a month of use Please answer these questions because I have heard that high temperature affects the life of the device The noise of the fan is annoying.

Scenario 2: Dell XPS 9570 Overheating Issues

Hi, my new XPS 9570 (i7-8750, 8g RAM, 1050Ti, 1080p Screen) overheats very easily and shuts down. It doesn’t appear to CPU throttle, it just runs itself until it overheats (CPU gets to over 96 C). When it overheats, the system does 1 of 2 things, it either: automatically shuts down, the screen goes blank, however, the Laptop stays on (fans running, keyboard lit, screen light remains on, but you can’t see anything on the screen). It appears to be running, but you can’t see anything and the laptop can’t be turned off for 5-10 minutes. It is not consistent either. I’ve played a very demanding video game sometimes for a few hours with no issues, and sometimes it overheats within minutes. Both of these scenarios happen with no other programs running. On another game, when I am on the Start Menu (not even in game), with no other programs running, the CPU will suddenly jump to 85+ C and the GPU will jump to 75+ C. Again, this is on the start menu, with nothing but some menu buttons and an image on the screen. My problem is that I’ve never had a laptop that seems to overheat so quickly at times when there should be almost no demand on it or its CPU and GPU (again, there is no throttling, it just overheats and shuts down). In addition, I am worried that this overheating could be causing damage to the CPU or GPU which will lead to a lower life expectancy of this product. I’m wondering if this is a common issue with the XPS, or is this something wrong with my laptop?

Like the above two Dell users there many others who are facing the overheating issue with their Dell PC. Let us follow the below troubleshooting steps to narrow down the cause and fix it.

You may also like: 

Run Dell ePSA Diagnostics

If any hardware component has failed, hardware test will let you know about it and you can replace that faulty hardware, start your system and then immediately keep on tapping F12, select Diagnostic to run the hardware test.

In case, no failure detected move on to the next step.

Check in BIOS

Start your system and then immediately keep on tapping F2, be on BIOS page for 5-10 minutes and check if the computer is overheating, restarting or shuts down, if any of these things happen by just being on BIOS screen means something may not be right with hardware components, you need to contact Dell in this case.

If the system is fine in BIOS mode then maybe its OS, driver or software issue.

Check for Physical Damage

Check inside the system if you can or take help of any techy person and look for any damage to the heatsink or fan, a broken or missing fan blade may not cool system effectively. If you find any damage, contact Dell, damaged parts are not covered under warranty but you can still contact Dell for out of warranty repair or contact a local technician, in case system is just out of the box and you received damaged brand-new system then you might get free service or exchange as per Dell Policy.

In case processor or motherboard has been replaced recently, check if thermal grease or thermal pads are applied or replaced after the repair. In case thermal grease or thermal pads is missing contact Dell to get the Heatsink or Motherboard replaced again.

Keep the System on a Flat Surface.

Do not use the laptop on a lap. When you keep it on the lap ventilation does not work, it blocks the air flow. Even using the system on bed for a long time may cause overheating because the clothes on the bed may block the ventilation system. Keep system on a table or any flat surface where air vents are not blocked and allow proper air flow to cool down the system. Make sure Air vents are clean.

Check for Fan Noise

Check for spinning noise whether fan makes fast spinning noise constantly or it’s periodic depending upon the usage of the system.

If it’s periodic like it spins for some time then stops, that means there is no issue and the fan is working as designed. The fan runs fast to cool down the system, I have seen this happening with my system when I run a heavy application or when there are multiple applications running.

In case fan noise is constant Contact Dell.

Update the BIOS

Visit the Dell support website to update the system drivers and BIOS to the latest version. Sometimes updating the BIOS and drivers fix the overheating issue. Visit this link , enter the service tag number of your PC and then update the BIOS. Make sure the battery is more than 10 percent and the charger is plugged into the system while updating the BIOS.

Check for Error Messages

We have come across a few errors which may be the cause of overheating:

1)  Alert! Air Temperature Sensor Not Detected error message displayed during boot– Contact Dell, Temperature Sensor or Motherboard may be the issue, may need to replace the Temperature Sensor or Motherboard.

2)  Heatsink Related Error Message: Clear the system event log– to clear system log open control panel, double-click Administrative Tools, and then double-click Event Viewer. In either pane of the Event Viewer window, right-click System (usually it’s under Windows Logs) and then select Clear log.

Event Viewer system log

  • Restart your system.
  • Check for heatsink Related Error Message?
  • Restart the system again, go to the BIOS using F2 at the Dell logo Screen.
  • Now Check the System Event Log for any Thermal Messages or Fan Failures.
  • In case there is no error in the event log, then the issue is resolved.
  • In case you find the same error in the Log again, then contact Dell as Motherboard may be the issue.

3) Fan related error message: Do the Following:

  • Reseat Fan Power Cables to the System board.
  • Get rid of any Dust or Debris in the PC’s Fans.
  • Check the System Event Log for any Thermal Messages or Fan Failures.
  • In case you do not find any error in the event log, then the issue is resolved.
  • In case of same error in the Event Log, then contact Dell as it may be faulty Fan.

4) Air Temperature error message: Do the Following:

  • Clear the system event log.
  • Get rid of any dust or other debris in the System’s fans.
  • Disconnect Third-party Hardware From the PC.
  • In case you have an add on graphics Card which has a Fan, make sure that the fan is spinning properly. In case it does not then replace the graphics Card.
  • Reseat fan Power Cables to the System board.
  • Run the ePSA Diagnostics by using F12 key at Dell logo screen.
  • In case of any failure while running the test, contact Dell to get the faulty part replaced.
  • In case of ePSA pass, check the OS Log file for any Hardware failures.
  • In case you don’t find anything then contact Dell for further help.


I hope this post helped you to fix or narrow down the cause of overheating, random shutdown and thermal issue on Dell systems.
