What to do to prevent the computer from going into sleep mode, how sleep differs from hibernation, how to turn off sleep mode when the laptop lid is closed and other common questions.
Why hibernate
Sleep mode is a kind of alternative to completely shutting down your computer or laptop. If you need to return to work after a while, then it is easier not to turn off the computer, but to put it into sleep mode. In this mode, the PC consumes less energy and does not make noise, but when you wake up from sleep, all open windows and programs will be in the same state.
How sleep and hibernation differ
Sleep and hibernation are very similar, but they work in different ways:
- when the computer is in sleep mode, the data on the current work is stored in the RAM, so the wake-up is quick;
- in hibernation mode, session data is written to a file, and upon shutdown, the system reloads it into RAM, which takes a little more time.
Each mode has its pros and cons. Disadvantages of hibernation - a slightly longer "wake up" and the need for free space on the hard disk, lack of sleep - loss of unsaved data in the event of a power outage. This happens because constant power is needed to store data in RAM.
Which is better: sleep, hibernate, or shutdown?
Sleep and hibernation modes are primarily used to save energy. If you do not plan to use the laptop for a while, but you do not want to turn it off due to the fact that many programs are open and the work is not finished yet. The same scenario is used on a stationary PC, with the only difference that you simply save electricity, not battery power.
However, hibernation and hibernation may not work properly: the computer may suddenly wake up, not go to sleep, or not shut down at all. There may also be conflicts with certain software or hardware. The most problem-free mode is full shutdown.
How to disable (remove) hibernation through Windows 10 settings
In Windows 10, hibernation can be turned off through the Windows settings. You can get there in two ways: press the key combination Win + I or right-click on the "Start" button, and then select "Options".
Select "System" and then on the left side of the "Power and Sleep" window. Here you can configure sleep mode for the monitor and the computer itself. If you have a laptop, the settings for mains power and battery power will be separately available.
How to disable (remove) hibernation through the Windows 10 control panel
For more detailed settings of the sleep mode, you can go to the control panel. To get to the desired window, go to "Power and sleep mode" and click on the link "Advanced power settings". You can also get to this section by entering the powercfg.cpl command in the Windows search or the Run utility (invoked via Win + R).
Here you can configure the power scheme. Now other parameters are important for us. Click on the Power Scheme Setup link next to the currently active plan.
In this window, you can enable or disable sleep mode for your computer and monitor. But you can go even further. Click the Change advanced power settings link. Pay attention to the item "Allow wake-up timers". If you are having problems when the computer spontaneously wakes up from sleep mode, then you need to turn off the timers.
How to disable (remove) hibernation in Windows 7
In the G7, disabling hibernation is not much different. You need to click "Start" and go to "Control Panel". Find the item "Power supply". Next, go to "Setting up a power plan". You can also get to this menu through the search: enter "Setting the transition to sleep mode".
Configure the settings for turning off the display and entering sleep mode as desired. You can go to advanced power settings, where there are also settings for sleep mode.
How to disable (remove) sleep mode when closing the laptop lid
To prevent the laptop from turning off, going into sleep mode or hibernating when you close the lid, you need to change the settings for this action. Go to Power Options. The easiest way will be to press Win + R and enter the command powercfg.cpl, but you can use the longer method from the previous paragraphs of the article.
On the left side of the window, find the links "What the power buttons do" and "What happens when the lid is closed." Click on any. In the window that opens, you can configure the parameters as you wish.
How to configure hotkeys and put your computer to sleep from the keyboard
If your keyboard has a separate button for switching to sleep mode, you can hang this action on it. There may also be an option with a keyboard shortcut. As a rule, this is the Fn function key, which is found on almost all laptops, but it can also be on the keyboards of stationary computers.
If your device does not have a dedicated button or keyboard shortcut, you can enter sleep mode by pressing the shutdown button. To reassign the actions, you need to go to the power options and repeat the steps from the previous paragraph of the article.
How to prevent keyboard and mouse from waking up from sleep mode
To prevent the system from waking up when moving the mouse or pressing the keyboard keys, you need to go to the "Device Manager". Next, right-click on the "Start" menu, and then go to "Device Manager".
Find the item "Mice and other pointing devices", double-click on the desired device and in the window that opens, go to the "Power management" tab. Uncheck the box next to Allow this device to wake up the computer. This method also works on other devices that can wake the computer from sleep.
What to do if your computer won't go to sleep
If your computer does not go to sleep or wakes up immediately, try the following:
- update your drivers (especially your motherboard and video card);
- check your power plan settings and turn off wake timers. Read more about this in the section "How to disable (remove) sleep mode through the control panel". It might be worth resetting your power plan settings to their original settings;
- prevent devices like keyboards or network cards from waking the PC from sleep. As a last resort, physically disconnect all unnecessary devices.
