Hi @FrDon 

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

If your HP laptop is displaying an overheating notification on boot, even though your systems (Ubuntu and Windows) are showing that the temperatures are cool, there may be several reasons for this issue. Let’s go through some potential causes and solutions.

1. Incorrect Temperature Readings or Sensor Issues

• Temperature sensors malfunction: It’s possible that the sensor or software detecting the temperature during boot is malfunctioning or giving incorrect readings.
• Solution: Check the BIOS/UEFI settings for temperature readings, as sometimes the error might only appear in the BIOS environment but not in the OS.
  • To access BIOS/UEFI:
    1. Shut down the laptop.
    2. Power it on and immediately press the Esc key (or F10, depending on the model).
    3. In BIOS, navigate to the Health or System Information tab to check the temperature.
  • Compare this reading with what is shown in your operating system once you boot up.
  • If the BIOS shows normal temperatures, the issue might be software-related in your operating system.

2. Dust Buildup or Poor Airflow

• Physical overheating: Even if your OS is reporting cool temperatures, there might still be an issue with airflow or dust buildup inside the laptop, causing localized hot spots that trigger the overheating warning.
• Solution: Clean the cooling system (fans, vents, etc.) using compressed air.
  1. Power off the laptop and disconnect it from power.
  2. Use compressed air to blow out any dust from the vents and cooling fans. Ensure that air is directed towards the intake and exhaust vents.

3. Thermal Paste Degradation

• Old thermal paste: Over time, the thermal paste between the CPU/GPU and heat sink can dry out or degrade, reducing its effectiveness in transferring heat. This can cause localized overheating, even if the temperature readings appear fine.
• Solution: If you're comfortable with hardware repairs, you can try to reapply thermal paste to the CPU/GPU. If you're not familiar with this process, you might want to take the laptop to a professional technician.

4. System Overload During Boot

• Excessive startup programs: If there are too many programs or services running during startup, it could cause the laptop to work harder than necessary, triggering the overheating warning.
• Solution: Disable unnecessary startup programs:
  • Windows:
    1. Open Task Manager (Ctrl + Shift + Esc).
    2. Go to the Startup tab and disable any non-essential programs.
  • Ubuntu:
    1. Open Startup Applications.
    2. Disable unnecessary programs from starting automatically.

5. Firmware or Driver Issues

• Incorrect fan or thermal management control: An issue with outdated firmware or drivers may cause the cooling system to not function optimally, even if the temperature readings seem normal.
• Solution:
  1. Update BIOS/UEFI: Check HP's website for any BIOS updates for your laptop model and follow their instructions to update the BIOS.
  2. Update Drivers: Ensure that your chipset, thermal management, and fan drivers are up to date. You can do this by going to Device Manager (Windows) or using apt or Software Updater in Ubuntu to check for updates.

6. Overheating Detection in BIOS/UEFI

• BIOS Overheating Detection: Some HP laptops might have a built-in overheating detection system that could show warnings during boot even if the OS reports cool temperatures. This may happen if the system detects issues with fan speeds or a sudden temperature spike.
• Solution: Try to reset BIOS settings to default to see if the warning persists.
  1. Access the BIOS/UEFI during boot (usually by pressing Esc or F10).
  2. Find the option to Reset to Default or Restore Factory Settings.
  3. Save changes and exit to see if the issue is resolved.

I hope this helps.

Take care and have a good day.
