Processor usage management for optimal power management under Windows 10/8/7

Many of you may have noticed that your Windows laptop gets hot when you use it intensively for resource-intensive tasks. Maybe the players noticed that too. Because in this case, your processor works in most cases with maximum efficiency, namely 100%. As a result, such intensive use can lead to wear and tear on the processor and therefore a shortened service life.

Starting with Windows 7, Microsoft has updated support for ACPI Processor Power Management (PPM) functions, including support for processor performance states and processor hibernation on multiprocessor systems.

To reduce overheating and extend battery life, you can monitor the status of your processor by monitoring its maximum usage. But you may have to compromise on performance.

Although in most cases it is best to leave the processor power management options at their default values, some of you may want to adjust them a little.

Open Control Panel > Power Options > Advanced Settings.

Here, under Processor Power Management, you can see three settings: Minimum processor status, maximum processor status, and system cooling policy.

The Minimum Processor State and Maximum Processor State parameters can be used to bring system processors to a specific processor inductance state. Default values vary from 5% (minimum) to 100% (minimum or maximum) depending on the power option used.

Minimum processor state



June 2019 Update:

We now recommend using this tool for your error. Additionally, this tool fixes common computer errors, protects you against file loss, malware, hardware failures and optimizes your PC for maximum performance. You can fix your PC problems quickly and prevent others from happening with this software:

  • Step 1 : Download PC Repair & Optimizer Tool (Windows 10, 8, 7, XP, Vista – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

It indicates the minimum processor performance state. The power state is expressed as a percentage of the maximum processor frequency. You can keep any value between 5% and 100%, depending on the power option used.

Maximum processor state

It indicates the maximum processor performance state. The power state is expressed as a percentage of the maximum processor frequency. If you notice that your laptop is overheating, you should set the maximum value to 90%.

This policy parameter determines how Windows responds to high thermal conditions on systems that support active cooling functions, such as fans. You have two options. Assets and liabilities.

      1. Active: Increases the fan speed before slowing down the processor. The system allows active cooling functions such as fans before it reduces processor performance.
      2. Passive: Slows down the processor before increasing the fan speed. The system reduces processor performance before activating active cooling functions such as fans.
