Hi @hassan105,

Welcome to HP Support Community.

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

The undervolting option being unavailable in the BIOS after an update is likely due to changes implemented to enhance system stability or address vulnerabilities such as Intel's Plundervolt exploit. This can be frustrating, especially with the high temperatures you're experiencing. Here are steps you can take to mitigate the issue.

Update the BIOS Again or Rollback to Previous Version:

• Check for New BIOS Updates: Sometimes, HP releases quick fixes after major updates. Check if a newer BIOS version is available.
• Rollback BIOS: If the undervolting option was available in the previous version, you might want to roll back to the earlier BIOS version. Follow HP’s BIOS rollback guide carefully.

Use Intel XTU or ThrottleStop:

• Intel Extreme Tuning Utility (XTU): You can try using Intel XTU, which allows for undervolting from within Windows (if supported on your CPU). Download and install the latest version to see if undervolting is still possible.
• ThrottleStop: This is another tool that may allow undervolting on some systems. It works similarly to XTU but can be more flexible. Check if it's compatible with your system.

Improve Cooling:

• Clean Dust from the Laptop: Dust buildup can cause high temperatures. Clean the vents and fans using compressed air.
• Use a Cooling Pad: A good cooling pad can help reduce temperatures by improving airflow.
• Repaste the CPU: If the thermal paste has degraded, repasting the CPU with high-quality thermal paste can improve heat dissipation.

Reduce CPU Power Usage:

• Limit CPU Performance: You can limit the maximum processor state to reduce heat under heavy loads. In Windows, go to:
  • Control Panel > Power Options > Change Plan Settings > Change advanced power settings > Processor power management.
  • Set "Maximum processor state" to 95% to reduce the frequency and heat generation.

Monitor Temperatures:

• Use software like HWMonitor or Core Temp to keep an eye on your CPU temperatures and performance.

I hope this helps.

Take care and have a good day.
