If you’re having difficulties with this error, here’s how to easily solve HP laptop error code 90b.
How do I fix the cooling system on my HP laptop?
1. Update BIOS
-
- The first thing you should do is check your laptop for any outstanding BIOS updates. The most recent BIOS update for your machine can be found on the HP website.
- Download HP Support Assistant software from the HP Support Assistant page here. If necessary, install the software.
- Start the program, go to the My Devices page, identify your computer, and click Updates.
- To obtain the most recent updates, go to “Check for updates and notifications.”
- Check the BIOS update box and select Download and Install if any updates are found.
- Once the update has been installed, close the Support Assistant. Restart the computer and see if anything has changed.
2. Clean the Air Vents and CPU Fans
-
- If the problem persists, it’s possible that dust has accumulated in the laptop’s outside vents, causing a temperature rise and, as a result, the mistake. It could also happen if your CPU’s thermal paste has dried out and needs replacement.
- Check the outside vents after shutting down the computer and blow air through the open vents to eliminate any dust buildup.
- Also, carefully clean the CPU fans before replacing the lid. Check for a resolution after restarting the computer.
- Check if the CPU thermal paste has dried out if the problem persists. Remove any residual thermal paste and reapply the new thermal paste. If you’re not sure how to accomplish it, get an expert.
- Check to see whether the error reappears after restarting the computer. Because the error is usually caused by a lack of heat, cleaning the air vents and reapplying the thermal paste should fix the problem.
3. Perform Hard Reset
-
- If the problem persists, try doing a hard reset. This will just reset the thermal values, allowing you to operate the system without error once more.
- Turn off the HP laptop to do a hard reset.
- Disconnect any external devices from your laptop. If the power cord is connected in, unplug it as well.
- To reset your laptop, press and hold the power button for 15 seconds. Take a break from your laptop for a minute or two.
- Now connect the power adapter to the wall outlet and the laptop to the power cord.
- Turn on the computer and see if there are any improvements.
