Windows 7 Disable Sleep Mode

Sleep mode in Windows 7 is theoretically a good idea for some users. It conserves energy by putting your computer into a low-power state. What’s nice is that sleep mode saves your open documents and programs to memory so you can return to your work as you left it.

The bad part about sleep mode is that it may prevent you from remotely accessing your office computer. If you’re at home, and your office computer is in sleep mode, chances are you won’t be able to access it. The only want a sleep mode computer may be woken up for remote access is if the office computer’s network adapter has a Wake On function. Otherwise, your computer won’t wake up!

Sleep & Hibernation in Windows

Sleep is a power-saving state that allows a computer to quickly resume full-power operation (typically within several seconds) when you want to start working again. Putting your computer into the sleep state is like pausing a DVD player—the computer immediately stops what it’s doing and is ready to start again when you want to resume working.

Hibernation is a power-saving state designed primarily for laptops. While sleep puts your work and settings in memory and draws a small amount of power, hibernation puts your open documents and programs on your hard disk, and then turns off your computer. Of all the power-saving states in Windows, hibernation uses the least amount of power. On a laptop, use hibernation when you know that you won’t use your laptop for an extended period and won’t have an opportunity to charge the battery during that time.

Hybrid sleep is designed primarily for desktop computers. Hybrid sleep is a combination of sleep and hibernate—it puts any open documents and programs in memory and on your hard disk, and then puts your computer into a low-power state so that you can quickly resume your work. That way, if a power failure occurs, Windows can restore your work from your hard disk. When hybrid sleep is turned on, putting your computer into sleep automatically puts your computer into hybrid sleep. Hybrid sleep is typically turned on by default on desktop computers.

Turn Off Sleep Mode in Windows 7

In Windows 7 you can adjust how long your computer waits before sleeping or hibernating — or prevent it from turning itself off altogether. Go to Start -> Control Panel -> Power Options.

Click the Change Plan link under any of the plans to get the Edit Plan Settings window as shown below. If you want for the computer to not go into Standby or turn off the screen select Never.

The window that opens (shown above) allows you to change settings for turning off the display and whether or not to put the computer to sleep. You can also change additional advanced settings by clicking on the "Change advanced power settings" link. When you have completed the power settings changes, click the Save changes button before closing the window.

Click Save changes to apply new settings. If you have troubles at any step - just watch video. There are some other interesting features - you can disable Hibernation using Command Line.

Configure Sleep & Hibernation in Command Line

For You can use the Powercfg.exe tool to control power settings and configure computers to default to Hibernate or Standby modes. The Powercfg.exe tool is installed with Windows and can be accessed in CMD. Here some settings you can use:

powercfg -change -monitor-timeout-ac 0

powercfg -change -monitor-timeout-dc 0

powercfg -change -disk-timeout-ac 0

powercfg -change -disk-timeout-dc 0

powercfg -change -standby-timeout-ac 0

powercfg -change -standby-timeout-dc 0

powercfg -change -hibernate-timeout-ac 0

powercfg -change -hibernate-timeout-dc 0

If you don’t use the Hibernate option in Windows 7, you can save some disk space by disabling it. Here we will look at a few different ways to manage hibernate options in Windows 7.

Using the Command Prompt might be the easiest way to enable or disable Hibernation. Click on Start and type CMD into the search box and it will be listed under programs. Right-click on the icon and select Run as administrator.

Type in the following to disable hibernation.

powercfg /hibernate off

The Command Prompt opens and you will use the following to enable Hibernation.

powercfg /hibernate on

If you always turn off your computer or never do, you can disable the Hibernate mode to gain a bit of extra hard disk space. That may not seem like much especially with today’s high capacity drives, but if you don’t need Hibernation, why not reclaim that space?
