What does C-State Auto Rule do?
 
In order to save energy when the CPU is idle, the CPU can be commanded to enter a low-power mode. Each CPU has several power modes and they are collectively called “C-states” or “C-modes.”.

The lower-power mode was first introduced with the 486DX4 processor. To the present, more power modes has been introduced and enhancements has been made to each mode for the CPU to consume less power in these low-power modes. The idea of these modes is to cut the clock signal and power from idle units inside the CPU. As many units you stop (by cutting the clock) as you reduce the voltage or even completely shut down to save energy. On the other hand, you have to take into account that more time is required for the CPU to “wake up” and be again 100% operational. These modes are known as C-states. They are usually starting in C0, which is the normal CPU operating mode, i.e., the CPU is 100% turned on. With increasing C number, the CPU sleep mode is deeper, i.e., more circuits and signals are turned off and more time the CPU will require to return to C0 mode, i.e., to wake-up. Each mode is also known by a name and several of them have sub-modes with different power saving – and thus wake-up time – levels.

Should i not update the BIOS? Yes or No


I dont have any issues with my computers, but should i update?
 

As a general rule, Never update a BIOS just to have the latest BIOS. Updating a BIOS falls in the "If it ain't broke, don't fix it" catagory. I would only update a BIOS to correct a known error that I am experiencing, or to gain additional functionality, such as support for a new CPU.
YMMV.
