Hi @13122,

Welcome to HP Support Community.  

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

If your HP Pavilion 15 laptop is displaying the "90D system temperature" error code during startup, it indicates that your system is overheating. This error code is a protective measure implemented by the BIOS to prevent damage to the internal components due to excessive heat.

Here are some steps you can take to address the overheating issue.

• Check for proper ventilation: Ensure that the laptop is placed on a flat surface and that the air vents are not blocked. Use your laptop on a hard, flat surface rather than on a soft surface like a bed or pillow, as this can obstruct airflow.
• Clean the air vents and fans: Over time, dust and debris can accumulate in the laptop's air vents and fans, leading to poor airflow and increased temperatures. Use compressed air or a soft brush to clean out the vents and fans carefully.
• Update your BIOS and drivers: Check the HP support website for any available BIOS or driver updates for your specific laptop model. These updates can include fixes and optimizations that may help improve the cooling system's efficiency.
• Adjust power settings: Reduce the power consumption of your laptop by adjusting the power settings. Lowering the brightness of the screen, disabling unnecessary startup programs, and setting the power plan to "Power Saver" mode can help reduce the heat generated.
• Use a laptop cooling pad: Consider using a laptop cooling pad, which is a dedicated device designed to improve airflow and dissipate heat. These pads typically have built-in fans to provide additional cooling.
• Avoid running demanding tasks: Avoid running resource-intensive tasks such as heavy gaming or video editing for extended periods, as they can generate significant heat. If you need to perform such tasks, take regular breaks to allow the laptop to cool down.

I hope this helps. 
 

Take care and have a good day.
