Ever since the introduction of PCs, microprocessors have been powering them. And as technology has evolved, so too has the way microprocessors are used. One such example is the use of C States. C States are short-term power-saving modes that can be activated by the BIOS. When enabled, they can save energy by disabling some of the more power-hungry components of the microprocessor.
In this blog post, we’re going to discuss how to disable C States in BIOS and why it might be useful for you. We’ll also provide a few tips on how to make sure your BIOS is configured correctly for this purpose.
What are C States?
C States are a power management feature in some computers that allow the computer to save battery life by suspending or halting the functioning of certain components when the computer is not being used. This can be helpful if you are using your computer primarily for work and don’t want it to constantly be turning on and off. However, C States can also cause problems if you’re trying to use your computer while it’s in C State, as it can prevent you from accessing certain functions or programs. If you experience any problems with your computer while it’s in C State, you can disable C States in BIOS to fix the issue.
How do they work?
Most modern processors feature C States, which are designed to save power by suspending the processor in certain states. However, some users may find that C States can cause problems with their system. This article provides instructions on how to disable C States in your BIOS.
How to disable C States in BIOS?
If you are looking to disable C States in your BIOS, there are a few different ways that you can go about it. The three most common methods are through the UEFI firmware, the COHERENT BIOS mode setting, or the ACPI settings.
To disable C States through UEFI firmware, open up your UEFI firmware and navigate to “Advanced > CPU Configuration”. Under the “Performance Mode” heading, select the option that says “Disable C-States”. Once you have enabled this setting, your computer will no longer enter C States when it is operating under load.
To disable C States through the COHERENT BIOS mode setting, open up your BIOS and navigate to “Advanced > CPU Configuration”. Under the “Performance” heading, change the setting from “Auto” to either “Enabled” or “Disabled”. This will determine whether or not your computer will enter into C States when it is operating under load.
Finally, if you want to disable C States through ACPI settings, open up your Windows 10 PC Settings and navigate to System > Advanced Settings > Performance.
There you will find a section called “Power management” which contains two options: “Allow Hybrid Sleep” and “Enable C-States”. If you select the first option (“Allow Hybrid Sleep”), then your computer will not enter into any power-saving modes (C States included) when it is operating in hybrid sleep mode.
There are three different ways to disable C States in BIOS: through UEFI firmware, COHERENT BIOS mode setting, or the ACPI settings. Each method has its own set of pros and cons, so it is important to choose the method that is best suited for your needs.
By disabling C States in BIOS, you can potentially save energy and avoid any problems that may be caused by the feature. If you experience any problems with your computer while it is in C State, you can disable C States in BIOS to fix the issue.
