Power management settings in BIOS (Power Management Settings)

This article will help you reduce the amount of electricity consumption by a laptop, netbook and desktop computer (regular PC or system unit).

Please note the owners of laptops and netbooks, this article is just for you. By disabling certain functions, you can extend the operating time of your device by an hour or more.

And so let's start analyzing the power consumption settings in the BIOS SETUP. In particular, for settings, the tab in the BIOS is called " Power management settings".

In the picture below you will see a tab"Power management settings" workingmicrocode chip Phoenix/Award.

Users often experience confusion in this area of ​​the BIOS. If not displayed correct settings, then the system will no longer shut down properly, nor will it exit the Standby or Hibernate states properly. Windows is already equipped with built-in power management, all relevant options in the BIOS can be turned off. Otherwise they will conflict with each other and neither will work correctly. Motherboard manufacturers understand that not everyone uses Windows, so most of the settings are intended for users of other operating systems.

And so let's move on to the analysis of the main options in the "Power Management Settings" tab.

ACPI Suspend to RAM: ACPI stands for Advanced Configuration and Power Interface - do not confuse it with APIC or IPCA, which are also available as options in some BIOSes. The Suspend to RAM feature, also called S3/STR, allows the computer to save more power in Standby mode, but all devices connected to the computer must be ACPI-compliant. Some BIOSes have an S1/POS option for this scenario. If you enable this feature and you have problems with standby mode, then go back to the BIOS and disable it.

Video Off Method (video off method): DPMS stands for Display Power Management System (DPMS). This option allows the BIOS to manage graphics card that supports the DPMS function. The Blank Screen option produces a blank black screen - this should be used for those monitors that do not support green options or power saving mode. The V / H SYNC Blank option not only produces a black screen, but also turns off vertical and horizontal scanning. If your computer and monitor are manufactured within the last five years, then we recommend the DPMS option.

HDD Down In Suspend (shutdown HDD in Suspend mode): the function determines whether the hard disk will automatically turn off in Suspend mode. Most of these settings are managed by Windows, but if your hard drive does not turn off when the computer enters Suspend, then enable this option. Otherwise, it's better to leave it disabled (Disabled).

PWR Button< 4 Secs (клавиша питания): By default, all ATX computers turn off if you hold down the power key for more than four seconds. This setting tells the computer what to do if the power key is held down for less than four seconds. You can either turn off the system or put it into Suspend mode. So decide for yourself.

Power Up On PCI Device (power up by PCI device): if you use Wake-On-LAN - this option is often used in large office environments to remotely turn on computers - then leave the option enabled (Enabled). Otherwise, we recommend turning this option off (Disabled).

Wake/Power Up on Ext. Modem (power on via external modem): this feature allows the computer to automatically turn on when activated telephone line modem. Yet again, handy feature for remote control. In other environments, that is, for most users, it is better to turn it off (Disabled).

Automatic Power Up ( automatic switch on): this function allows you to set the time when your computer will automatically turn on. If you need such a function, then turn it on (Enabled). Otherwise, turn off (Disabled).

AC Power Loss Restart (power on after power loss): this option tells the computer what to do after an unexpected power loss and restore it. If the option is disabled (Disabled), then the system will not start. If enabled (Enabled) - the system will be rebooted. We recommend turning this option off (Disabled).

Power On By PS / 2 Mouse (power on by PS / 2 mouse): if this option is enabled, a PS/2 mouse (not USB) can be used to turn on the PC. Turn off (Disabled) this option to not turn on the computer by accidentally touching the mouse.

Power On By PS/2 Keyboard (power on by PS/2 keyboard): By activating this function, you can turn on the system using special keys. It is better to turn off the function (Disabled) so as not to accidentally make a mistake with the key.

Attention: If you have a Windows operating system on your laptop, you need to disable all options in the "Power Management Settings" section in the BIOS SETUP.

How to turn off the computer's power saving mode and set the maximum performance.

Turn off the computer's power-saving mode

1. Disabling the computer's power-saving mode in the BIOS

To disable the computer's energy-saving mode in the "BIOS" (for example, the BIOS from Asus), you need to press the F2 or Delete key at the beginning of the boot (if anyone does not know).

When you entered the BIOS and go to the section AI Tweaker, such a section is available in all modern motherboards. In older versions, it may not be, in general, you won’t know until you get into it.

The name of the section may differ depending on the manufacturer, but in any case, you already know where and what to look for, so do not get lost.

We find in this section the line EPU Power Saving Mode(EPU power saving mode) and set to Disable(Disable).

» EPU Power Saving Mode- responsible for activating proprietary energy-saving technology ASUS EPU. It is a software and hardware complex that controls the load on the system and, if necessary, automatically changes the parameters of the main components (processor, video card, drives, random access memory, chipset and cooler) to save power. To achieve maximum results during overclocking of components, it is recommended this function turn off. »

High performance in windows 7, windows 8 and windows 10

To turn on high performance, you need to click start - control panel - power options.

By default, High Performance is hidden. On the right, click on the arrow in the circle and mark the item High performance.

The same is done in Windows 10. The screenshots below show everything:

You can also create your own power plan. To add your own plan, click "more information about power plans"

After the "scheme name" field appears at the bottom

Where you can enter your own scheme name and set your parameters and settings.

Here are the main ways available to you to turn off energy saving and improve the performance of a computer or laptop with windows 7, 8 and 10 operating systems.

Computers have features that many do not use, although they can significantly improve the experience with the system. For example, the power mode appeared in Windows 98, but few people know about it.

Using it, the user can distribute and save battery power. You can also one of the options to complete the work. And finally, using one of the energy-saving modes, you can save electricity. Of course, this option is unlikely to greatly affect the situation with one PC, but in any enterprise it is possible to solve problems with high bills.

Computer energy

Many people want to know how to disable power saving mode. But, before talking about it, it is worth understanding what requires the most energy in a PC.

As practice shows, the monitor and hard drive are demanding. For example, the display usually works in normal mode when both blocks are involved: horizontal and vertical scanning. In this case, it can take up to 100 watts.

In standby mode, horizontal scanning is disabled, but the monitor can return to normal very quickly. But you can save up to 90% of energy consumption. If you use a mode in which the vertical scan is disabled, you can save 10-15% of power consumption.

The hard drive works about the same. It can be sent to Before this, the PC will save all the final work of the programs. And then stop accessing the hard drive.

Hibernation works a little differently. In this case, on HDD all information about the current state is saved operating system so you can quickly get back to work. This option will not require power consumption to save data.

There is also a "hybrid sleep" that combines features of the previous two modes. It saves files open programs on RAM, and creates a hibernation file to save system data.

Power supply

By default, almost all modes are immediately present on the PC. Therefore, many people want to know how to turn off the power saving mode. All information on this topic is located in the "Power Options" menu.

To get to it, you need to click on the battery icon in the tray right click mice. Thus, a list of options will appear in which you must select "Power Options".

You can also use the Control Panel. To do this, click on "Start" and on the right we find the desired line. A dialog box will open with a list of system functions. In it you need to find "Power Supply".

Power Plan

In the new dialog box, you will have to figure out how to turn off the power saving mode. Two plans are immediately available to the user: balanced and economical. The system recommends using a balanced one as it balances the performance and power consumption of the PC.

The economy plan will not help you turn off the power saving mode in Windows 7, because it is designed just to save energy in absolutely everything.

A high performance plan is also available on the system, but it is hidden. In this case, the system can start all the necessary and unnecessary processes, so the computer's energy consumption will increase noticeably.

Plan setup: laptop

Before thinking about how to turn off power saving mode, you can try setting up a power saving plan. On the left in the column you can find the function "Create a power plan". Here you can enter the name of the new plan, and then start setting up.

If you have a laptop, then two columns of settings will be available to you: “On battery” and “On the network”. Therefore, each parameter will have to be configured separately, for different situations. If you always use the laptop from the mains, then for the "Battery" mode, you can not touch anything at all.

In the power plan, you can set the time after which the display is dimmed or turned off, as well as the activation of sleep mode. It is difficult to recommend anything in this case, since everything depends on the user.

Plan setup: computer

How to disable power saving mode on a computer? Here the situation is somewhat different. It could be said that this is easier to do. When you get to the menu for creating a power plan, you see only two options that you can configure:

• turn off the display;
• putting the PC into sleep mode.

If you want to completely turn off energy saving, you can choose not a specific time, but the item "Never". In this case, the display will never turn off and sleep mode will never turn on.

Editing existing power plans

On a computer, power saving mode works the same way as on a laptop. You can adjust existing settings, as well as further configure power settings.

In this case, it does not matter what version of the operating system you have. Windows systems. How to disable power saving mode on the computer in this case? You need to open the line "Change advanced power settings", and then carefully look at all the available settings options.

Customization options

Available standard plans will be listed at the top of the dialog box. Near the selected mode, it will be indicated that it is “active”. Then you can start editing it.

For example, you can configure the hard drive. If you understand the system, you can try to set a certain time after which the hard drive will be turned off. If you do not understand this matter at all, it is better not to do anything.

Next, you can configure the work Internet Explorer. Here you can change the frequency of the JS timer. Set by default maximum performance. Below you can adjust the desktop background settings. Slideshow is available in Balanced Power Mode. If necessary, it can be disabled.

Below you can turn off the power saving mode Windows computer 7. In the "Sleep" line, you can find not only sleep mode, but also hibernation, which is in laptops. If you do not need any of this, you can simply set the value to zero or "Off". But there are a lot of useful settings here.

For example, you can set the time after which the PC will go to sleep. Next, you can enable hybrid sleep, and below set the time after which hibernation will turn on. The last setting item is also very important. Here you can set wakeup timers.

You may have encountered such a problem that you sent your PC to sleep, and after some time it turned on by itself. This usually happens because some system events are set to wake it up. To prevent this from happening, you can turn off the timers.

In the parameters there is a setting to temporarily disable USB ports. Below you can configure how the device behaves when the power button is pressed. For example, you can set a command for it, in which the PC will not turn off, but go into sleep mode. There is also a setting for the laptop lid.

Below you can configure the processor power. Adjust its minimum and maximum state, as well as the cooling policy.

Here you can customize the screen.

Screen power consumption

How to turn off power saving mode on LG monitor? The following tip will work for any other display model. Staying in the advanced power options dialog box, you can continue to customize the screen. The user can change the operating time of the monitor, as well as adjust the brightness.

In the first case, you can choose the time after which the screen will turn off completely. You can also try adaptive brightness control. It allows you to monitor light sensors to detect changes in lighting and select the desired brightness level.

BIOS

And finally, how to disable power saving mode in BIOS? First you need to switch to this mode. Next, you need to find the AI ​​Tweaker section, in which we select the EPU Power Saving Mode line. This is the power saving mode setting. Therefore, it will be enough to put the Disable value in front of it, which will disable it.

Modern processors have long used energy-saving technologies. Various big names are used to identify and promote them, but the essence remains the same - a change in the performance of CPU elements depending on the load. If a module is not used, then it is logical to “freeze” it, which will reduce power consumption and heat dissipation. The former is not essential for non-mobile platforms, but increased heat generation may be important, since the desire for silence is a general trend in the development of equipment and is highly demanded by users.

Power saving is good, but how does it affect computer performance? About this and will be discussed below.

Energy Saving Technologies

No need to worry, I will not waste your time listing dozens of intricate terms and names in this area, they are all based on two concepts:

The second technique has been used relatively recently, as an addition to the first - in some cases, it is possible to reduce the operating frequency of idle nodes, which will not cause a performance loss. As soon as the frequency has been reduced, then the operating voltage can be proportionally reduced to it. The lower the voltage and frequency, the lower both the power consumption and the "background" leakage current through the semiconductor crystal.
