Power Management in BIOS Settings

Power Management in BIOS Settings

BIOS settings provide a way to manage power consumption and thermal management for hardware devices. In this article, we will explore the different options available in the Power menu of a typical BIOS setup.

OS Power Management (OS 전원 관리)

The OS Power Management option allows you to enable or disable runtime power management and change the idle power saving settings. This option is useful for managing power consumption when running on battery or trying to prolong battery life.

Hardware Power Management (하드웨어 전원 관리)

The Hardware Power Management option enables or disables power management settings for devices such as SATA, S4, and S5. This option allows you to manage power consumption for specific hardware components.

Thermal (과열) Settings

The Thermal setting displays the CPU fan speed. This option is useful for monitoring and managing system temperature and noise levels.

Advanced (고급) Menu

The Advanced menu provides more detailed options for power management, bus settings, and device settings. The following options are available:

  • Power-On Options (전원 켜짐 옵션): Change the behavior of the computer when it is powered on or off.
  • BIOS Power-On (BIOS 전원 켜기): Set the date and time at which the computer will automatically power on.
  • Bus Options (버스 옵션): Enable or disable advanced bus options for improved performance.
  • Device Options (장치 옵션): Change the behavior of devices such as keyboard keys.

Using the Keyboard

The BIOS setup utility provides a range of keyboard shortcuts to navigate and configure settings. The following are some common keyboard shortcuts:

  • Left or right arrow key: Move to the previous or next menu option.
  • Up or down arrow key: Select an item from the list.
  • Enter: Execute the command or select a sub-menu.
  • F10: Save changes and exit the BIOS setup utility.
  • Esc (Escape): Cancel changes and exit the BIOS setup utility.

Restoring Default Settings

If you need to restore default settings, you can use the BIOS setup utility's File tab. Follow these steps:

  1. Select the File tab in the BIOS setup utility.
  2. Click on Apply Defaults and Exit.
  3. The BIOS setup utility will exit and reboot the computer into Windows.

Resetting CMOS

If your motherboard requires a specific CMOS reset, you can follow these steps to restore default settings:

  1. Shut down the computer and disconnect the power cord from the motherboard.
  2. Locate the CMOS battery on the motherboard.
  3. Remove or disconnect the CMOS battery.
  4. Verify that all power is removed from the system or disconnected.
  5. Press the power button for at least 60 seconds to discharge all power from the system and reset the CMOS values.
  6. Reconnect or reinstall the CMOS battery.
  7. Assemble the computer and reconnect the power cord.
  8. Power on the computer, and the BIOS will display a message indicating that the CMOS has been reset.

Verifying CMOS Reset

After resetting the CMOS, verify that the time is set to 00:00 in the BIOS settings. If not, repeat the process and hold the power button for at least 120 seconds.

By understanding the various options available in the Power menu of your BIOS setup utility, you can optimize system performance and manage power consumption effectively.
