Energy Management Settings in BIOS (Power Management Settings)
This article will help you to reduce the amount of electricity consumption by a laptop, a netbook and a stationary computer (a regular PC or Systemist).
Please note the owners of laptops and netbooks, this article is just for you. Disconnecting certain functions, you can extend the operation time of your device for an hour or more.
And so I will proceed to the analysis of power consumption settings in the BIOS Setup. In particular, to configure the tab in the BIOS is called " Power Management Settings".
On the bottom of the bottom you will see the tab"Power Management Settings"Working Chip on the microcodePhoenix / Award.
In this area of \u200b\u200bBIOS, users often observe confusion. If the correct settings are not set up, the system will stop off properly, and will not correctly exit Standby or Hibernate states. Windows is already equipped with built-in power management, all corresponding options in the BIOS can be turned off. Otherwise they will conflict with each other, and none will work correctly. Motherboard manufacturers understand that Windows does not use everything, so most of the settings are intended for users of other OS.
And so let's proceed to the analysis of the basic options in the "Power Management Settings" tab.
ACPI Suspend To Ram: ACPI Indicates an enhanced configuration and power interface (Advanced Configuration and Power Interface) - do not confuse it with APIC or IPCA, which are also present as options in some BIOS. The Suspend to RAM function is also called S3 / STR, allows the computer to save more energy in standby mode (STANDBY), but all devices connected to a computer must be ACPI compatible. Some BIOS for this script exists an S1 / POS option. If you enable this feature and you will have problems with the wait mode, then return to the BIOS and turn it off.
Video Off Method (video shutdown way): DPMS is deciphered as controlling the monitor power saving mode (Display Power Management System). This option allows BIOS to manage a graphics card that supports the DPMS feature. Option Black Screen (Blank Screen) gives an empty black screen - it should be used for those monitors that do not support green options or energy saving mode. The V / H Sync Blank option not only gives a black screen, but also turns off the vertical and horizontal scan. If your computer and monitor are released in the last five years, then we recommend the DPMS option.
HDD DOWN IN SUSPEND (HDD shutdown in Suspend mode): The function determines whether the hard disk will turn off in Suspend mode. Most of these settings are managed by Windows, but if your hard disk does not turn off when the computer enters Suspend sleep mode, then enable this option. Otherwise it is better to leave it off (disabled).
Pwr Button.< 4 Secs (клавиша питания): By default, all ATX-computers are turned off if you hold the power key more than four seconds. This setting tells the computer that should be done if the power key will hold less than four seconds. You can turn off the system and translate it into Suspend mode. So decide for yourself.
POWER UP ON PCI DEVICE (Enable PCI): If you are using Wake-On-LAN - this option is often used in large office environments to remotely enable computers - then leave the option enabled (Enabled). Otherwise, we recommend turning off this option (disabled).
Wake / Power Up ON EXT. Modem (inclusion of an external modem): This feature allows the computer to automatically turn on when the modem telephone line is activated. Again, a convenient feature for remote control. In other environments, that is, for most users, it is better to turn it off (disabled).
Automatic Power Up (automatic switching on): This feature allows you to set the time when your computer will automatically turn on. If you need a similar function, turn it on (enabled). Otherwise, turn off (disabled).
AC POWER Loss Restart (inclusion after loss of power): This option tells the computer that he should do after the unexpected loss of nutrition and its recovery. If the option is disabled (disabled), the system will not be launched. If enabled is enabled - then the system will be rebooted. We recommend turning off this option (disabled).
POWER ON PS / 2 MOUSE (Mouse Enable PS / 2):if the option is enabled, the PS / 2 mouse can be used to turn on the PC (not USB). Turn off (disabled) this option so as not to turn on the computer, accidentally affect the mouse.
POWER ON PS / 2 KEYBOARD (PS / 2 keyboard switching on): When you activate this feature using special keys, you can turn on the system. It is better to turn off the function (disabled) so as not to be mistaken by chance.
ATTENTION: If you have a Windows operating system on a laptop, you need to disable all options in the "Power Management Settings" section of the BIOS SETUP.
Most modern desktops and laptops have very advanced BIOS or UEFIs that allow you to configure those or other machine operation parameters. One of the additional functions of the BIOS is the power saving mode that is not always required. Today we want to tell you how it can be turned off.
To begin with - a few words about what is the power supply mode. In this mode, the processor consumes energy in a minimum that on the one hand saves electricity (or battery charge in the case of laptops), but on the other, it reduces the power of the CPU, which means when performing complex operations can be brazed. Also, the power saving mode must be disconnected if the processor is accelerated.
Disable energy saving
Actually, the procedure is quite simple: you will need to go to the BIOS, find the settings of the power modes, and then turn off the power saving. The main difficulty lies in the diversity of BIOS and UEFI interfaces - the desired settings may be located in different places and are called differently. Consider all this variety within the same article looks inappropriate, so we will dwell on one example.
Attention! All further action you spend on your own risk, we are not responsible for possible damage that may arise in the process of execution of the instruction!
- Log in to the BIOS - To do this, restart the computer, and at the boot stage, press one of the function keys ( F2. or F10) or key Delete.. Please note that some manufacturers use different login diagrams of the motherboard.
- After entering the firmware control interface, look for tabs or options, in the title of which the words appear "POWER MANAGEMENT", "CPU POWER MANAGEMENT", ADVANCED POWER MANAGEMENT or similar in meaning. Come in the corresponding section.
- Further action options are also different for different bios: for example, in the given one you want to switch the option in the screenshot. "POWER MANAGEMENT" in the Regulation "User Defined". In other interfaces, this can also be implemented or the change change options will be available immediately.
- Next, look for settings that are related to energy saving: as a rule, combinations appear in their names. "ENERGY EFFICIENT", "Power Saving" or "Suspend". To disable power saving, these settings need to be switched to the position. "OFF", as well as "DISABLE" or "NONE".
- After making changes to the settings, they must be saved. In most options, the BIOS is responsible for saving the settings. F10. You may also need to go to a separate tab of the save, and apply settings from there.
Now the computer can be rebooted and check how it behaves with a disabled power saving mode. Consumption should increase, as well as the amount of heat released, therefore it may additionally need to configure the corresponding cooling.
Possible problems and solutions
Sometimes, when executing the procedures described, the user may encounter one or more difficulties. Let's consider the most common.
In my BIOS no power settings or they are inactive
In some budget models of motherboards or laptops, the BIOS functionality can be significantly trimmed - "under the knife" manufacturers are often allowed and functionality of power management, especially in solutions designed for low-power CPUs. There is nothing to do anything - you have to accept it. However, in some cases, these options may not be available by the manufacturer error, which is eliminated in the latest firmware options. 
In addition, power management options can be blocked as a kind of "fool protection", and open if the user tasks the access password.
After turning off the power saving mode, the computer does not load the system
A more serious failure than the previous one. As a rule, in most cases, such means that the processor is overheated, or it lacks the power of the power supply for full operation. You can solve the problem to discharge the BIOS to the factory settings - for details, read the article on the link below.
Conclusion
We reviewed the method of disconnecting the power saving mode in the BIOS and solve some problems that occur during or after the procedure.
In computers, there are functions that many do not use, although they can noticeably improve work with the system. For example, the power consumption mode appeared in Windows 98, but a few people know about him.
Using it, the user can distribute and save battery charge. You can also finish one option. Well, 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 at any enterprise you can solve problems with high accounts.
Computer energy
Many want to know how to disable energy-saving mode. But before talking about it, it is worth understanding that most of all requires energy in the PC.
As practice shows, monitor and hard drive are demanding. For example, the display usually works in normal mode when both blocks are involved: horizontal and vertical sweep. In this case, it can take up to 100 watts.
In idle mode, the horizontal scan is turned off, but the monitor can return to normal state very quickly. But you can save up to 90% of energy consumption. If you use the mode in which the vertical sweep is disabled, you can save 10-15% of energy consumption.
Hard disk works approximately. It can be sent in front of this PC will save all the final work of the programs. And after stopping access to the Winchester.
Hibernation works somewhat differently. In this case, all information about the current state of the operating system is saved on the hard disk, so you can quickly return to operation. This option will not require energy consumption to save data.
There is also a "hybrid sleep", which combines the features of the previous two modes. It saves open open-memory files on RAM, and creates a hibernation file to save the system data.
Power Supply
By default, almost all modes are immediately present on the PC. Therefore, many want to learn how to turn off the energy-saving mode. All information on this topic is in the "Power" menu.
To get to it, you must click on the battery icon in the three mouse right. Thus, a list of options appears in which you want to select "Power".
You can also use the control panel. To do this, click on the "launch" and on the right we find the desired string. A dialog box opens with a list of system functions. It needs to find "Power Supply".
Power Plan
In the new dialog box, you will have to figure out how to disable energy-saving mode. Two plans are immediately available to the user: balanced and economical. The system recommends using a balanced, since it keeps the balance between performance and PC power consumption.
The economical plan will not help disable energy-saving mode in Windows 7, since it is designed just to save energy in everything.
The system also features a high performance plan, but it is hidden. In this case, the system can launch all the necessary and unnecessary processes, so the energy consumption by the computer will increase significantly.
Setting the Plan: Laptop
Before you think how to disconnect the energy-saving mode, you can try to configure the energy saving plan. On the left in the column you can find the "Create Power Plan" function. Here you can enter the name of the new plan, and after starting the setting.
If you have a laptop, you will be available two settings columns: "From the battery" and "from the network". Therefore, each parameter will have to be configured separately for different situations. If you always use a laptop from the network, you can not touch anything for the "From the Battery" mode.
In the Power Plan, you can configure the time after which the display is darled or disabled, as well as the inclusion of sleep mode. Recommend anything in this case is difficult, since it all depends on the user.
Plan Setup: Computer
How to disable energy-saving mode on your computer? The situation is somewhat different. It would be possible to say what to do it easier. When you hit the power plan menu, you see only two parameters that can be configured:
- disconnection of the display;
- pC translation into sleep mode.
If you want to completely disable energy saving, you can choose not a certain time, and the item "Never". In this case, the display will never turn off, and sleep mode is turned on.
Editing existing power plans
On the computer, the energy-saving mode works in the same way as on the laptop. You can adjust the existing settings, as well as adjust the power parameters.
In this case, it does not matter which version of the Windows operating system you have. How to turn off the energy-saving mode on the computer in this case? You need to open the "Change additional power parameters" string, and after carefully view all the available settings options.
Setup options
At the top of the dialog box will indicate the available standard plans. Near the selected mode it will be stated that it is "active." Next you can start editing it.
For example, you can configure the hard disk operation. If you understand the system, you can try to set a certain time by the expiration of the hard drive. If you do not understand this case at all, it is better not to do anything.
Next, you can configure Internet Explorer. Here you can change the frequency of the JS timer. The default maximum performance is installed. Below you can adjust the desktop background parameters. In a balanced power mode, a slideshow is available. If necessary, it can be turned off.
Below you can disable the energy-saving Windows 7 computer mode. In the "Sleep" string, you can find not only sleep mode, but also hibernation that is in laptops. If you don't need anything from this, you can simply set the zero value or "off". But here the mass of useful settings.
For example, you can set the time after which the PC will go to sleep mode. Next, you can resolve the hybrid sleep mode, and below set up the time after which hibernation will be turned on. The last setting item is also very important. Here you can adjust the awakening timers.
Perhaps you came across such a problem that I sent a PC to sleep mode, and after some time he independently joined. This usually happens, because some system events are installed that awaken it. So that this does not happen, you can turn off the timers.
The parameters are configured to temporarily disable USB ports. Below you can configure how the device will behave when the power button is pressed. For example, you can set the command for it, in which the PC will not be turned off, and go to sleep mode. There is here and setting for a laptop cover.
Below you can adjust the power of the processor. Adjust the minimum and maximum state, as well as cooling policies.
Immediately you can configure the screen operation.
Screen power consumption
How to disable energy-saving mode on the LG monitor? The following advice is suitable for any other display model. Staying in the dialog box with additional power parameters, you can continue the screen setting. The user is available to change the monitor time, as well as adjustment of brightness.
In the first case, you can choose the time after which the screen will be turned off completely. You can also try adaptive brightness adjustment. It allows you to monitor the lighting sensors to determine the change in lighting and select the desired brightness level.
BIOS
And finally, how to disable energy-saving mode in bios? First you need to go to this mode. Next, you need to find the AI \u200b\u200bTweaker section, in which you select the EPU Power Saving Mode string. This is setting the power saving mode. Therefore, it will be enough to put opposite it the value of Disable, which will turn off.
How to disable power saving computer mode and set maximum performance.
Turning off the power saving computer mode
1. Power Saving Power Saving Mode of Computer in BIOS
To disable the computer's energy saving mode in "BIOS" (on the example of bios from ASUS), it is necessary at the beginning of the download (if anyone does not know) Press the F2 or Delete key.
When they entered 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, while you can't get driving.
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.
Find in this section line EPU POWER SAVING MODE(EPU energy saving mode) and put in position Disable(Disable).
» EPU POWER SAVING MODE - responsible for activating branded 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 cards, drives, RAM, chipset and cooler) to save electricity. To achieve maximum results during the acceleration of components, it is recommended to turn this function. "
High performance in Windows 7, Windows 8 and Windows 10
To enable high performance, you need to press Start - Panel Control - Power Supply.
By default, the High Performance Point is hidden. On the right, click on the arrow in the circle and mark item High performance.
Similarly, it is done in Windows 10. The following in the screenshots is shown:
Screenshot 1. 
Screenshot 2. 
Screenshot 3. 
Screenshot 4. You can also create your own power scheme. To add your diagram to click "For more information about power management schemes"
After appearing at the bottom of the "Scheme name" field
Where you can enter your own diagram name and set your parameters and settings.
Windows 10 power supply scheme Here you have available basic ways to disable power saving and improving computer performance or laptop with Windows 7, 8 and 10 operating systems.
Modern processors have long used energy-saving technologies. For their identification and promotional promotion, various loud names are used, but the essence remains the same - the change in the performance of the CPU elements depending on the download. If some module is not used, it logically "freeze it", which will reduce the power of consumption and heat dissipation. The first is irrelevant for non-clean platforms, but the increased allocation of heat may be important, since the desire for silence is a general trend of the development of equipment and extremely demanded by users.
Energy saving is good, but how does it affect the performance of the computer? This will be discussed below.
Energy Saving Technologies
No need to worry, I will not spend your time at the presentation of dozens of wisdom terms and titles of this area, they are all based on two concepts:
The second reception began to be applied relatively recently, as an addition to the first - in some cases, you can reduce the working frequency of idle nodes, which will not cause performance loss. Since the frequency has soon reduced, then it is possible to simulate to simulate and the working voltage. The smaller the voltage and frequency, the lower both the power of consumption and the "background" current of leakage on the semiconductor crystal.
