Sleep mode is a power-saving feature that is enabled by default on new computers. It is designed to save power when the computer is inactive by shutting down most components while keeping the system state in memory for quick resumption. While this feature is useful, it can be frustrating when your monitor refuses to wake up from sleep mode. This is a common issue with no universal cause or solution, but there are several ways to troubleshoot and resolve this problem.

What You'll Learn
Move your mouse back and forth a few times
If your monitor is in sleep mode, the status LED on the front panel will be yellow. To wake it up, you can try moving your mouse back and forth a few times. This is a popular method, as it's convenient and intuitive.
To ensure that this method works, you should first check your device settings. On Windows, go to the Control Panel and look for 'Power Options' under 'Device Manager'. Here, you can enable the 'Allow this device to wake the computer' option. This setting ensures that a simple mouse movement can bring your computer out of sleep mode. After making any adjustments, remember to click 'OK' to save your changes.
If moving the mouse doesn't work, you can try pressing any key on your keyboard or the power button.

Press any key on your keyboard
Pressing any key on your keyboard is one of the easiest ways to wake your monitor from sleep mode. Sleep mode is a power-saving state that allows your computer to quickly resume full-power operation, usually within a few seconds, when you want to start working again.
To enable this feature, access the device's properties in the Device Manager and select the 'Power Management' tab. Here, you will see the option 'Allow this device to wake the computer'. Make sure this option is checked. This setting ensures that a simple mouse movement or keypress can bring your computer out of sleep mode. After adjusting your computer's power settings, remember to click 'OK' to save the changes.
If your monitor is still not waking up, you can try pressing the "Input" button on your monitor's front panel repeatedly at three- or four-second intervals until your monitor wakes up. If your monitor is set to an incorrect input mode, it won't receive a video signal. Resetting the monitor to the proper input mode will resolve this issue.
Additionally, you can try changing your monitor input settings. For example, some users have reported that changing the input selection from "HDMI" to "AUTO" has helped their monitor wake up from sleep mode.

Check your power connections
If your monitor is not waking up from sleep mode, you should first check your power connections. Monitors will wake up from sleep mode when they detect a video signal from the computer. If the monitor does not wake up, ensure that the computer is not in sleep or hibernate mode itself. Move your mouse or press any key on your keyboard to check. If this does not work, press the power button to wake up the computer.
If the computer is not in sleep mode, check if the video cable is plugged in properly. Disconnect and reconnect the video cable if necessary. You can also try pressing the "Input" button on your monitor's front panel repeatedly at three- to four-second intervals until your monitor wakes up. Your monitor will not receive a video signal if it is set to an incorrect input mode. Resetting the monitor to the proper input mode will allow it to receive the signal and wake up automatically.
If your monitor continues to enter standby mode, you may need to change your power and sleep settings. On a Windows computer, go to Start > Settings > System > Power & Battery > Screen and Sleep. Here, you can adjust how long your device waits before turning the screen off or going to sleep. You can also select your power mode, optimising for performance or power efficiency.
If you are still unable to wake your monitor from sleep mode, you may need to shut down and restart your computer.

Change your monitor input selection
If your monitor is in sleep mode, the status LED on the front panel will be yellow. To wake it up, try moving your mouse back and forth a few times. If this doesn't work, press any key on your keyboard. If your monitor still doesn't wake up, press the "Input" button on your monitor's front panel repeatedly at three- or four-second intervals until it wakes up. If your monitor is set to an incorrect input mode, it won't receive a video signal, so resetting the monitor to the proper input mode will allow it to receive the signal and wake up automatically.
To change your monitor input selection, you may need to refer to your monitor's manual or manufacturer instructions. However, here are some general steps you can follow:
- Identify the input source: Determine the input source you want to use, such as HDMI, DisplayPort (DP), or VGA.
- Locate the input buttons: On your monitor, look for buttons labelled with the input options, such as "Input", "Source", or the specific input types like "HDMI".
- Select the desired input: Press the corresponding button for the input source you want to select. For example, if you want to switch to HDMI, press the "HDMI" button.
- Wait for the signal: After selecting the input, your monitor will search for the signal from the selected source. This may take a few seconds.
- Confirm the change: Once the input is selected and the signal is detected, your monitor should display the image from the chosen source.
It's important to note that the specific steps and buttons may vary depending on your monitor model and brand. Some monitors may have an "Auto" input selection, which automatically detects and switches to the active input source. If you're having trouble finding the correct input, try switching to "Auto" if available, or consult your monitor's user manual for model-specific instructions.
Additionally, if you're using a Windows computer, you can adjust the power settings to ensure that a simple mouse movement or keypress can wake your computer from sleep mode. Here's how:
- Open the Control Panel: Go to the Start menu and search for "Control Panel".
- Navigate to Power Options: In the Control Panel, look for "Power Options" or "Power Management".
- Adjust the settings: Under Power Options, make sure the "Allow this device to wake the computer" setting is enabled. This will allow your computer to respond to mouse or keyboard input to wake up.
- Save the changes: After making the desired adjustments, click "OK" or "Apply" to save the changes.

Adjust your computer's power management settings
If you're having trouble with your monitor not waking up from sleep mode, there are several things you can try to adjust your computer's power management settings.
Firstly, you can try adjusting the power settings through the Control Panel. To do this, press the Windows key on your keyboard, type "Control Panel" into the search bar, and press Enter. Once the Control Panel window opens, click on the Hardware and Sound category, then select Power Options. On the left side of the Power Options screen, you'll see an option called "Change when the computer goes to sleep". Click on this, and you'll be able to modify your sleep settings. You can select how long you want your device to wait before turning off the screen and going to sleep, both when it's plugged in and when it's running on battery power.
Another way to adjust power and sleep settings in Windows is through the Settings menu. Press the Windows key + I on your keyboard to open the Settings menu, then select System. In the System menu, look for Power & sleep (Windows 10) or Power & battery (Windows 11) on the left sidebar. Here, you can adjust the timeout settings for your screen and sleep mode, similar to the Control Panel method.
Additionally, you can explore more power-saving options by selecting "Additional power settings". This will allow you to change how your device uses power and access advanced power settings. For example, you can enable hybrid sleep mode, which balances accessibility and energy savings. If you want to keep your computer awake while reducing power draw, you can also try turning off peripherals like your monitor and speakers, or using energy-efficient components.
It's worth noting that some monitor brands have special features like Deep Sleep, which further reduces power usage. If you don't find this feature useful, you can disable it in your monitor settings.
