What are all the advanced power settings in Windows?



Windows has many "advanced power settings" that you can adjust. These options allow you to choose between performance and battery life, check what Windows does when you have a critical battery level and tweak what pushes the power switch and closes the lid.

This works on all modern versions of Windows, including Windows 1

0 and Windows 7.

To find advanced power settings

To find these options, go to Control Panel> Hardware and Sound> Power Options. Click the "Change plan settings" link to the right of the energy plan that you want to configure.

Each power plan has its own advanced option configuration, so you can quickly switch between combinations of settings.

Click on "Modify Advanced" Power Settings "to find these options.

What All Advanced Power Settings Do

Different Windows computers have different options here depending on the hardware. For example, a laptop with a battery will have separate settings for "On battery" and "Plugged in" while a desktop PC without battery has only one setting that you can change for each option. Some Windows 10 systems use "Modern Standby" and have very few options.

In the window at the top of the window you can Quickly choose between the power plans of the system so that you can adjust all of its settings from this window. The power plan you are currently using is marked "[Active]."

Now let's find out

Hard Disk> Turn Off Hard Drive After : Windows usually closes the hard drive when the computer is idle, and this allows you to control how many minutes before it happens. This is typically a sleep mode. Your hard drive is turned off, but your computer will turn it on again as soon as needed. Turning off the hard drive when not in use saves power and increases the computer's battery life. Turning off the hard drive too aggressively will damage performance, as it takes a while to spin back to life.

This option only affects internal physical hard drives-you know the mechanical with spinning magnetic plates and not modern solid state drives (SSDs).

Internet Explorer> JavaScript Timer Frequency : If you never use Internet Explorer, you can ignore this setting. This option allows you to select either "Maximum Performance" or "Maximum Power Savings". The "Maximum Power Savings" option is standard on laptops, which will slow down the web site's low-performance webpage performance to increase your laptops battery life. But this only affects Internet Explorer. It's an old option that does not affect modern browsers.

Desktop Wallpaper Settings> Slideshow : With Windows, you can set a slideshow as desktop wallpaper. The option here allows you to "Pause" the slideshow if you like. For example, an energy-saving power plan may pause the slide show when you're on the battery, and another power plan can re-enable when connected to a jack.

Wireless Adapter Settings> Power Save Mode : 802.11 The Power Save protocol helps save your computer's Wi-Fi radio. With this feature, your Wi-Fi radio can go to bed and tell the wireless access point (router) that it does. This saves power and increases battery life. The options here let you check how aggressive this is. The "Maximum Performance" mode is the default when connected to the power; it disables the energy saving model. The "Medium Power Saving" mode is standard when you have battery power. You can also select "Low Power Save" or "Maximum Power Save" for either.

Microsoft notes that some wireless hotspots do not support this feature correctly and problems may arise when they are connected to them if enabled. So if you have Wi-Fi issues, you may want to try to disable it. Or, if you need to pin more battery life from your laptop, try this option for Maximum Power Save. In theory, the Wi-Fi radio can sleep more often increase latency and reduce network performance, but you get more battery life.

Sleep> Sleep After : Your computer can automatically go to sleep when not in use, saving power. The computer enters a low power state where most of the hardware is turned off, but it can continue almost immediately when you start using it again.

This option allows you to define the number of minutes of inactivity before the computer goes to sleep. For example, you might want your laptop to go to sleep after five minutes of inactivity on the battery.

These are the same options that you can configure from Control Panel> Hardware and Sound> Power Options> Change when the computer is asleep.

Sleep> Allow Hybrid Sleep : Hybrid Sleep is a combination of sleep and sleep mode. It is intended for desktop computers, not laptops. With Hybrid Sleep, your desktop computer will save system status to both your memory (as sleep) and hard drive (as hibernation) when it goes asleep. It will stay in a low energy state and wake up quickly, and you can continue the work. If there is a power failure, you can restore your system status from the hard disk so you will not lose anything.

By default, this option is enabled on desktops and is usually turned off from laptops. It's because it would use more power on laptops. Laptops do not need this feature as much. If there is a power failure, the notebook has a battery to keep it running while the desktop computer closes immediately if it is not connected to a power-off (UPS.)

Sleep> Hibernation after : Your computer can automatically hibernate, save system status to disk. Unlike hibernation, hibernation uses almost no power. It will continue from where you left when you started it again. However, it takes longer to restore from hibernation, and it takes power to save system status to the hard drive.

This option allows you to check for how many minutes of inactivity your computer rests. For example, you can sleep after five minutes, but sleep after three hours.

Sleep> Allow alarm clocks : Even when the computer stops, programs on your computer can set "wake up hours" telling that it wakes automatically at a certain time. For example, Windows wake timers tells your computer to wake up at specific times for system updates.

This option allows you to check whether wake hours are enabled or disabled on the entire system. If you select "Disable", even Windows will not be able to wake up your computer for updates. There is also only the "Important Wake Timers Only" option on Windows 10. This disables most alarms, but still allows Windows to wake up the computer for critical tasks like system updates.

[USBSettings>USBSelectiveSetupSetting: Windows can automatically turn off connected USB devices to save power when not using them. This setting may cause problems with some USB devices that can not be resumed from closing properly so you can disable it if it causes problems with a peripheral.

If you disable this and leave USB devices connected, they will not enter Suspend mode, and your computer will use more power. This is especially important on a laptop with battery power, as it can reduce battery life.

] Intel (R) Graphics Settings> Intel (R) Graphics Power Plan : If your computer has Intel graphics, you can use this graphics for Intel graphics cards that are connected to a Windows Power Plan. As usual, it is a balance between battery life and performance. "Maximum Battery Life," "Balanced Mode," and "Maximum Performance" are all available. You can adjust the settings for each Intel graphics power plan from the Intel HD Graphics Control Panel.

Buttons and Locks> Lock Close Action : If you use a laptop with a lid, this lets you control what happens when you close the lid while the computer is turned on. Available options are Make nothing, Sleep, Hibernate and Shut down.

You can also find this option on Control Panel> Hardware and Sound> Power Options> Select what closes the lid.

Power Buttons and Caps> Power Button Action : Here you can control what happens when you press the computer's physical power switch. You can choose from Do nothing, Sleep, Hibernation, Shut down or Shut down screen.

The same option is available on Control Panel> Hardware and Sound> Power Options> Select what the power switch is doing.

Buttons and Caps> Sleep Button Action : Here you can control what happens when you press the computer's physical sleep button if it has one. This includes Sleep buttons you can have on a PC keyboard. You can choose from Do nothing, Sleep, Hibernation mode and Shut down screen.

PCI Express> Link State Power Management : Here the protocol is checked Active State Power Management that is used to handle serial PCIe devices. When these devices are not working much, your computer can place them in low power mode to reduce power consumption. But they take awhile to wake up, which may increase latency when communicating with these devices.

With "Off" selected, you have the least latency but no energy saving. With "Maximum Power Savings" selected, you have the most latent and most energy-saving. "Moderate Power Savings" is a compromise between the two.

Processor Power Management> Minimal Processor Status : Windows adjusts the processor clock speed to save power when not in use. This is the lowest that your processor will go and it is by default 5%. It's a good number, and we do not recommend changing it unless you know what you're doing.

Processor Power Management> System Cooling Policy : Here you can choose your "cooling policy". With "Active" selected, Windows will increase fan speed to cool the processor and only reduce processor speed if it can not cool the processor enough fan. This results in higher performance and is a good choice on a desktop computer.

With "Passive" selected, Windows will slow down the processor speed to cool it down and just turn on the fan if it needs to cool down the CPU unit further down. This results in lower performance but less power consumption and longer battery life, so it's a better option for a laptop with battery power.

Processor Power Management> Maximum Processor Status : This is your highest speed processor will go. The default value is 100% which is a good number. You can try to reduce the number, but we are not sure that it will save power.

For example, if you chose 80%, your computer would need to spend more time in 80% mode to get the same amount of work done, it could get in 100% mode before you go down to its lowest state.

Display> Turn off the screen after : Windows can turn off the computer screen when you are not using your computer. This setting controls the number of minutes that Windows waits before turning off the screen.

This is the same setting as you can control from Control Panel> Hardware and Sound> Power Options> Select when to turn off the screen.

Multimedia Settings : The multimedia settings here are used when your computer shares the media with a protocol such as DLNA, which is built into Windows. In other words, these settings are used when the computer acts as a media server. They are not used when watching videos or playing music on your computer. Most people never need to touch these options.

Multimedia Settings> When Sharing Media : This option lets you choose what happens when your computer acts as a server. You can choose "Prevent Sleeping" to stop sleeping while streaming from it or choose "Let Your Computer Sleep" if you do not want people to keep it awake.

Or you can choose "Let Your Computer Get Into Removal" instead. Microsoft has explained what Away Mode does.

Multimedia Settings> Video Playback Quality Bias : You can choose whether your computer prefers video quality (due to power and battery life) or energy saving (at Video quality cost. The two options available here are "Video Playback Performance Bias "and" Video Playback Power Save Bias. "

Multimedia Settings> When playing video : When playing a video, choose whether your computer should" Optimize video quality, "" Optimize energy saving, "or select "Balanced" for a compromise.

We are not sure why this option is distinguished from Video Playback Quality Bias. This option controls the "Power Optimizer mode used by the computer's video playback guidance."

B attery> Critical Battery Explanation : Windows will show you a message when the battery reaches a critical low level if this option is set to "On." If set to "Off," you will not receive a message. By default it is on.

Battery> Critical Battery Action : Windows will take action when the battery reaches a critical level to prevent the computer from suddenly dying due to a blank battery, provided it is properly calibrated. Available options include Sleep, Hibernate, and Shut Down.

Battery> Low Battery Level : This checks the battery level that Windows considers to be low. For example, if you set it to 12%, Windows shows you a low battery message and leaving the battery at 12% battery.

Battery> Critical Battery Level : This controls the battery level that Windows considers to be critical. For example, if you set it to 7%, Windows displays a critical battery alarm and takes the critical battery at 7% remaining battery.

Battery> Low Battery Message : Windows usually shows you a notification when the battery reaches the low level. You can set this to "Off" to disable the message.

Battery> Low Battery Action : Windows can take action when the battery reaches the low level. Available options include Do not, Sleep, Hibernate and Shut Down.

Battery> Reserve Battery Level : Here the battery level is checked where Windows enters the "reserve power mode". Microsoft does not provide much information about this mode, but it appears that you will be warned to connect your notebook to a power source or at least save your documents when "Reserve Power Mode" logs in.

You can also mouse over many of these settings to find a quick sentence explaining what each does if you need it.
