Remove old thermal compound from integrated circuits and heat sinks and replace with new thermal compound. If not working correctly, replace the system fan. Make sure wires from the system and CPU fans are connected securely to the motherboard.Ĭonfirm the system fan blades spin correctly, and the fan is not producing loud noises. Thoroughly remove dust from all internal cooling components. Make sure to address the following items when servicing: Have the computer serviced to clean internal components and replace the system fan if necessary. In some cases, updating the BIOS might help prevent this error from occurring.įor more information on how to update the BIOS, see Updating the BIOS.
Performing a hard reset can reset recorded thermal values in memory and enable you to use the computer again, even if only for a short time to access and save any important files before service.įor more information on performing a hard reset, see Use Hard Reset to Resolve Hardware and Software Issues.
If the error message persists, continue with these steps. Dust can accumulate inside the vent openings and around internal cooling components, preventing the removal of heat.įor more information on reducing heat inside your computer, see Reducing Heat Inside the PC.Īfter you remove the dust, turn on the computer. Shut down the computer, and then inspect and clean the exterior vents to remove dust buildup by blowing air through the vent openings. Press Enter to clear the message and allow the system to boot to the Windows Desktop. Any ideas? I still want to explore options to prior to either returning thsi laptop for another one or sending it for repair. I have also noticed that the fans start to work when the temps reach around 55C. Once the computer is "warmed up" after some use, rebooting doesn't show the error. One thing I've noticed though is that I often get this if I do a cold start meaning the computer hasn't been used for quite some time and there is no need for the fans to work. The fans are working but I still get this error. I've already done a firmware upgrade and also upgraded Windows to version 2004. As per the HP support site aside from defective fans it could also be that the fans are dirty (I've cleaned them using canned air just to be sure) or a software problem. And the error appeared one day after I got the laptop. I know this is a common topic but as far as I know this happens when the laptop has quite some age. I have a brand new HP Pavilion 15-dk0056wm and I get the dreaded 90b system cooling error.
