Отключение режима энергосбережения в BIOS

Выключаем Power Saving Mode

Для начала – несколько слов о том, что такое режим энергосебережения. В этом режиме процессор потребляет энергию на минимуме, что с одной стороны позволяет экономить электроэнергию (или заряд батареи в случае ноутбуков), но с другой уменьшает мощность CPU, отчего при выполнении сложных операций могут быть подтормаживания. Также режим энергосбережения нужно отключать, если планируется разгон процессора.

Отключение энергосбережения

Собственно процедура достаточно простая: потребуется зайти в БИОС, найти настройки режимов питания, а затем отключить энергосбережение. Основная сложность заключается в разнообразии интерфейсов BIOS и UEFI – нужные настройки могут находиться в разных местах и называться по-разному. Рассмотреть всё это разнообразие в пределах одной статьи выглядит нецелесообразным, поэтому остановимся на одном примере.

Внимание! Все дальнейшие действия вы проводите на свой страх и риск, мы не несём ответственности за возможные повреждения, которые могут возникнуть в процессе выполнения инструкции!

1. Войдите в BIOS – для этого перезагрузите компьютер, и на этапе загрузки нажимайте одну из функциональных клавиш (F2 или F10), либо клавишу Delete. Обратите внимание, что некоторые производители используют разные схемы входа в режим управления материнской платой.
   

Подробнее: Как войти в BIOS
После захода в интерфейс управления микропрограммой ищите вкладки или опции, в названии которых фигурируют слова «Power Management», «CPU Power Management», «Advanced Power Management» или похожее по смыслу. Заходите в соответствующий раздел.

Дальнейшие варианты действий также отличаются для разных БИОС: например, в приведённом на скриншоте варианте нужно первым делом переключить опцию «Power Management» в положение «User Defined». В других интерфейсах это может быть реализовано так же или опции изменения режимов будут доступны сразу.

Далее ищите настройки, которые связаны с энергосбережением: как правило, в их названиях фигурируют сочетания «Energy Efficient», «Power Saving» либо «Suspend». Для отключения энергосбережения эти настройки нужно переключить в положения «OFF», а также «Disable» или «None».

Теперь компьютер можно перезагрузить и проверить, как он ведёт себя с отключённым режимом энергосбережения. Потребление должно повыситься, как и количество выделяемого тепла, поэтому может дополнительно понадобится настроить соответствующее охлаждение.

Возможные проблемы и их решения

Порой при выполнении описываемых процедур пользователь может столкнутся с одной или несколькими трудностями. Давайте рассмотрим наиболее распространённые.

В моём BIOS нет настроек питания или они неактивны
В некоторых бюджетных моделях материнских плат или ноутбуков функционал BIOS может быть значительно урезан – «под нож» производители часто пускают и функционал управления питанием, особенно в решениях, рассчитанных на маломощные CPU. Тут уже ничего не поделать – придётся смириться с этим. Впрочем, в некоторых случаях эти опции могут быть недоступны по ошибке производителя, которая устранена в новейших вариантах микропрограммы.

Кроме того, опции управления питанием могут быть заблокированы в качестве своеобразной «защиты от дурака», и открываются, если пользователь задаст пароль доступа.

После отключения режима энергосбережения компьютер не загружает систему
Более серьёзный сбой, чем предыдущий. Как правило, в большинстве случаев подобное означает, что процессор перегревается, или ему не хватает мощности блока питания для полноценной работы. Решить проблему можно сбросом BIOS до заводских настроек – для подробностей ознакомьтесь со статьёй по ссылке далее.

Saving Energy with VSync Control

To save power on a computer, your kernel-mode display driver can reduce the number of VSync monitor refresh interrupts that occur.

Newer processors and platforms often work with the operating system to conserve energy when the computer system is idle. However, periodic system activity, such as the firing of interrupts, causes peak power usage and can prevent the computer system from entering transient sleep states that would conserve energy.

Beginning with WindowsВ Vista with Service PackВ 1 (SP1) and Windows ServerВ 2008, the operating system can turn off periodic VSync interrupt counting when the screen is not being refreshed from new graphics or mouse activity. By controlling the VSync interrupt interval, your driver can save significant energy.

You can take advantage of this feature by rebuilding Windows Display Driver Model (WDDM) drivers by using the Windows ServerВ 2008 or later versions of the Windows Driver Kit (WDK).

WindowsВ Vista with SP1 Driver Changes for VSync Control

For drivers to take advantage of this feature, they must support the VSyncPowerSaveAware member in the DXGK_VIDSCHCAPS structure that was introduced in WindowsВ Vista with SP1. Existing drivers that follow the WDDM must be recompiled with the VSyncPowerSaveAware member by using the Windows ServerВ 2008 or later versions of the WDK.

A WindowsВ Vista with SP1 or later system with a driver that follows the WDDM and that supports this feature will turn off the counting feature of the VSync interrupt if no GPU activity occurs for 10 continuous periods of 1/Vsync, where VSync is the monitor refresh rate. If the VSync rate is 60 hertz (Hz), the VSync interrupt occurs one time every 16 milliseconds. Thus, in the absence of a screen update, the VSync interrupt is turned off after 160 milliseconds. If GPU activity resumes, the VSync interrupt is turned on again to refresh the screen.

Display-Only VSync Requirements for Windows 8 and later versions

In WindowsВ 8 and later versions of the Windows operating system, it’s optional for a kernel mode display-only driver (KMDOD) to support VSync functionality, as follows:

Display-only driver supports VSync control

If the KMDOD supports the VSync control feature, it must implement both DxgkDdiControlInterrupt and DxgkDdiGetScanLine functions and must provide valid function pointers to both of these functions in the KMDDOD_INITIALIZATION_DATA structure.

In this case the KMDOD must also implement the DxgkDdiInterruptRoutine and DxgkDdiDpcRoutine functions in order to report VSync interrupts to the operating system.

In addition, the values of the PixelRate, hSyncFreq, and vSyncFreq members of the DISPLAYCONFIG_VIDEO_SIGNAL_INFO structure cannot be D3DKMDT_FREQUENCY_NOTSPECIFIED.

Display-only driver does not support VSync control

If the KMDOD does not support the VSync control feature, it must not implement either DxgkDdiControlInterrupt or DxgkDdiGetScanLine functions and must not provide valid function pointers to either of these functions in the KMDDOD_INITIALIZATION_DATA structure.

In this case the Microsoft DirectX graphics kernel subsystem simulates values of VSync interrupts and scan lines based on the current mode and the time of the last simulated VSync.

In addition, the values of the PixelRate, hSyncFreq, and vSyncFreq members of the DISPLAYCONFIG_VIDEO_SIGNAL_INFO structure must be set to D3DKMDT_FREQUENCY_NOTSPECIFIED.

If these conditions are not met, the DirectX graphics kernel subsystem will not load the KMDOD.

Registry Control

For WindowsВ Vista with SP1 and later versions of the Windows operating systems, the default VSync idle time-out is 10 VSync periods. Optionally, for testing purposes, the time-out can be controlled by using registry settings.

To avoid application compatibility problems, do not change the default registry setting in production drivers.

Key Path:
RTL_REGISTRY_CONTROL\GraphicsDrivers\Scheduler

Full Path:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Scheduler]

Key Value:
VsyncIdleTimeout

ValueType:
REG_DWORD

Value:
10 = default

Value:
0 = disable VSync control (produces the same behavior same as Windows Vista)

Energy efficiency

Small steps make a difference

Use of electronic devices inevitably involves energy consumption. Microsoft is committed to reducing the environmental impact caused by the energy use of our products, including battery chargers.

Microsoft devices comply with the EU Ecodesign Directive for Energy-related Products (2009/125/EC) and its implementing regulations («Ecodesign Directive») when applicable. Our devices comply with the European Commission’s Regulation for Standby and Off Mode Power Consumption for Electronic Household and Office Equipment, and U.S. federal and state energy conservation standards when applicable. Microsoft devices meet the U.S. Department of Energy, California, and other regional and country-specific energy efficiency requirements.

We work to improve energy-saving features throughout our product portfolio, including the use of energy-efficient chargers, to help our customers save energy. Small steps make a big difference. All our devices come with power-saving standby settings. We have also introduced applications, features, and technologies (such as ambient light sensors, efficient Snapdragon™ processors, and OLED or AMOLED displays) to save energy.

All covered products meet the voluntary ENERGY STAR® standard.

Energy consumed by consoles

An important part of our business strategy includes reducing the energy consumed by our game consoles within a generation while maintaining the same level of gaming power. For example, since the launch of Xbox 360 in 2005, our engineering teams have successfully reduced standby power by a factor of 10 to less than three-tenths of a watt, resulting in a 60 percent reduction in energy use. Our development and compliance engineers ensure all our products meet regulatory requirements such as the Ecodesign Directive.

Carrying lessons learned from Xbox 360 forward, we continued our commitment to reduce energy usage through the design of Xbox One, launched in 2013. Xbox One provides eight to 10 times the processing power of Xbox 360. Despite this significant increase in processing power, the electrical power required for gaming is 30 percent less than that of its predecessor when it launched in 2005. Power needed for media play and dashboard use is half that of the Xbox 360 at launch. The increase in energy efficiency results from scalable processor architecture that wasn’t available for the Xbox 360. Other efficiencies are gained by providing the user with choices about console functionality while in standby mode.

Energy conservation: 10 ways to save energy

Last updated 12/23/2020

There are many different ways to reduce your household’s energy use, ranging from simple behavioral adjustments to extensive home improvements. The two major motives for conserving energy are to save on utility bills and protect the environment. Here are the ten most common ways to conserve energy and save electricity in your home, listed from the simplest to the most intensive methods.

Energy conservation made easy: the top 10 ways to save energy

1. Adjust your day-to-day behaviors

To reduce energy consumption in your home, you do not necessarily need to go out and purchase energy efficient products. Energy conservation can be as simple as turning off lights or appliances when you do not need them. You can also use energy-intensive appliances less by performing household tasks manually, such as hang-drying your clothes instead of putting them in the dryer, or washing dishes by hand.

The behavior adjustments that have the highest potential for utility savings are turning down the heat on your thermostat in the winter and using your air conditioner less in the summer. Heating and cooling costs constitute nearly half of an average home’s utility bills, so these reductions in the intensity and frequency of heating and cooling offer the greatest savings.

There are tools you can use to figure out where most of your electricity is going in your home and which appliances are using the most electricity on a day-to-day basis.

2. Replace your light bulbs

Traditional incandescent light bulbs consume an excessive amount of electricity and must be replaced more often than their energy efficient alternatives. Halogen incandescent bulbs, compact fluorescent lights (CFLs), and light-emitting diode bulbs (LEDs) use anywhere from 25-80 percent less electricity and last 3 to 25 times longer than traditional bulbs.

Although energy efficient bulbs are more expensive off the shelf, their efficient energy use and longer lifetimes mean that they cost less in the long run.

3. Use smart power strips

“Phantom loads,” or the electricity used by electronics when they are turned off or in standby mode, are a major source of energy waste. In fact, it is estimated that 75% of the energy used to power household electronics is consumed when they are switched off, which can cost you up to $200 per year. Smart power strips, also known as advanced power strips, eliminate the problem of phantom loads by shutting off the power to electronics when they are not in use. Smart power strips can be set to turn off at an assigned time, during a period of inactivity, through remote switches, or based on the status of a “master” device.

4. Install a programmable or smart thermostat

A programmable thermostat can be set to automatically turn off or reduce heating and cooling during the times when you are asleep or away. When you install a programmable thermostat, you eliminate wasteful energy use from heating and cooling without upgrading your HVAC system.

On average, a programmable thermostat can save you $180 per year. Programmable thermostats come in different models that can be set to fit your weekly schedule. Additional features of programmable thermostats can include indicators for when to replace air filters or HVAC system problems, which also improve the efficiency of your heating and cooling system.

5. Purchase energy efficient appliances

On average, appliances are responsible for roughly 13% of total household energy use. When purchasing an appliance, you should pay attention to two numbers: the initial purchase price and the annual operating cost. Although energy efficient appliances might have higher upfront purchase prices, their operating costs are often 9-25% lower than conventional models.

When purchasing an energy efficient appliance, you should look for appliances with the ENERGY STAR label, which is a federal guarantee that the appliance will consume less energy during use and when on standby than standard models. Energy savings differ based on the specific appliance. For example, ENERGY STAR certified clothes washers consume 25% less energy and 45% less water than conventional ones, whereas ENERGY STAR refrigerators use only 9% less energy.

6. Reduce your water heating expenses

Water heating is a major contributor to your total energy consumption. Other than purchasing an energy efficient water heater, there are three methods of reducing your water heating expenses: you can simply use less hot water, turn down the thermostat on your water heater, or insulate your water heater and the first six feet of hot and cold water pipes.

If you are considering replacing your water heater with an efficient model, you should keep in mind two factors: the type of water heater that meets your needs and the type of fuel it will use. For example, tankless water heaters are energy efficient, but they are also a poor choice for large families as they cannot handle multiple and simultaneous uses of hot water. Efficient water heaters can be anywhere between 8% and 300% more energy efficient than a conventional storage water heater.

7. Install energy efficient windows

Windows are significant source of energy waste — they can add up to 10-25% of your total heating bill. To prevent heat loss through your windows, you can replace single-pane windows with double-pane products instead.

For homes in colder regions, gas-filled windows with “low-e” coatings can significantly reduce your heating expenses. In addition, interior or exterior storm windows can reduce unnecessary heat loss by 10 to 20 percent. You should especially consider storm windows if your region experiences frequent extreme weather events.

In warmer climates, heat gain through windows may be a problem. In addition to minimizing heat loss, low-e coatings on windows can reduce heat gain by reflecting more light and lowering the amount of thermal energy that enters your home. Depending on where you live, ENERGY STAR windows can save you $20-$95 each year on your utility bills. Window shades, shutters, screens, and awnings can also provide an extra layer of insulation between your home and outside temperatures, leading to even more energy conservation.

8. Upgrade your HVAC system

An HVAC system is composed of heating, ventilation, and air conditioning equipment. Heating alone is responsible for more than 40% of home energy use. Because homes in Northern regions are exposed to much colder temperatures during the year, ENERGY STAR gas furnaces have different specifications in the northern and southern halves of the United States.

Upgrading to a “U.S. South” ENERGY STAR certification can save you up to 12% on your heating bill, or an average of $36 per year. ENERGY STAR furnaces in the northern half of the U.S. are labeled with the standard ENERGY STAR logo and are up to 16% more energy efficient than baseline models. This translates to average savings of $94 per year on your heating bill in the Northern U.S.

Air conditioning, by comparison, isn’t a significant contributor to energy bills – on average, it only makes up six percent of the total energy use of your home. ENERGY STAR central air conditioning units are eight percent more efficient than conventional models. Air conditioning systems are usually integrated with heating systems, which means that you should purchase your new furnace and air conditioner at the same time in order to ensure that the air conditioner performs at its maximum rated energy efficiency.

Upgrades to the third component of an HVAC system – ventilation – can also improve your energy efficiency. A ventilation system is composed of a network of ducts, which distributes hot and cold air throughout your home. If these ducts are not properly sealed or insulated, the resulting energy waste can add hundreds of dollars to your annual heating and cooling expenses. Proper insulation and maintenance on your ventilation system can reduce your heating and cooling expenses by up to 20%.

9. Weatherize your home

Weatherizing, or sealing air leaks around your home, is a great way to reduce your heating and cooling expenses. The most common sources of air leaks into your home are vents, windows, and doors. To prevent these leaks, you should ensure that there are no cracks or openings between the wall and vent, window, or doorframe.

To seal air leaks between stationary objects, such as the wall and window frame, you can apply caulk. For cracks between moving objects, such as operable windows and doors, you can apply weather stripping. Weather stripping and caulking are simple air sealing techniques that typically offer a return on investment in less than a year. Air leaks can also occur through openings in the wall, floor, and ceiling from plumbing, ducting, or electrical wiring.

Air leaking out of your home is most often from the home interior into your attic through small openings. Whether it is through ducts, light fixtures, or the attic hatch, hot air will rise and escape through small openings. As the natural flow of heat is from warmer to cooler areas, these small openings can make your heating bill even higher if your attic is not sufficiently insulated. To reap the full amount of savings from weatherization, you should consider fully insulating your home.

10. Insulate your home

Insulation plays a key role in lowering your utility bills through retaining heat during the winter and keeping heat out of your home during the summer. The recommended level of heat resistance, or “R-value,” for your insulation depends on where you live. In warmer climates, the recommended R-value is much lower than for buildings located in colder regions like the Northeast.

The level of insulation you should install depends on the area of your house. Your attic, walls, floors, basement, and crawlspace are the five main areas where you should consider adding insulation. Use the Home Energy Saver tool for recommendations based on the specifications of your home, or find general regional recommendations on the Department of Energy’s webpage on insulation.

Why conserve energy in the first place?

Energy conservation is important and beneficial for many reasons. You can save money, increase your property value, and protect the environment all through simple energy-saving measures. These are great benefits you can gain from saving energy no matter your exact motivation for conservation in the first place. By simply taking a small step towards living a more energy-conscious lifestyle, you can begin to enjoy all of the perks of being energy efficient.
