Sleep mode is a power-saving state that stops all actions on a computer or monitor. It moves open documents and applications to the system memory (RAM) and puts the device into a low-power state. This feature is useful for those who want to reduce their power consumption and quickly resume normal, full-power operation within a few seconds. However, some people prefer to shut down their monitors completely to ensure they are not drawing any power, even though modern eco-friendly monitors draw very little power in sleep mode. Additionally, some users have reported issues with monitors not turning on immediately after being turned off, which can be avoided by using sleep mode instead. Ultimately, the decision to use the sleep feature depends on individual preferences and priorities regarding power consumption, convenience, and performance.

What You'll Learn
Power-saving mode
Sleep mode is a power-saving state that stops all actions on a computer. Any open documents and applications are moved to the system memory (RAM) and the computer goes to a low-power state. This is similar to pausing a movie DVD. The computer is still powered on, but uses less power. Devices such as monitors also use sleep or standby mode to reduce power consumption.
Monitors can be set to enter sleep mode after a certain period of inactivity. This can be set by the user, who can select how long they want the device to wait before going to sleep when they are not using it. This can be done by going to the power settings on a computer and selecting the desired sleep settings.
Sleep mode is useful for saving power and can be a convenient way to quickly pause work and return to it later without having to shut down and restart the computer. It can also be useful for those who want to keep their computer running, but not the monitor, such as when watching videos before sleep.
However, some people prefer to turn off their monitors completely when not in use, rather than using sleep mode. This may be due to a preference for completely shutting down electronics when not in use, or because of a belief that it may prolong the life of the monitor. Some users also report issues with monitors not turning on properly after being turned off, so they prefer to leave them on.
In terms of power saving, modern eco-friendly monitors draw a minimal amount of power when in sleep mode, so the difference between sleep mode and turning off may be negligible. Additionally, some power is required to monitor the on/off switch, so there may be little difference in power consumption between the two states.
Ultimately, the decision to use sleep mode or turn off a monitor depends on user preference and their specific use case. Those who want to save power may prefer to use sleep mode, while those who want to ensure the longest life for their monitor may prefer to turn it off completely when not in use.

Standby mode
To wake a computer or monitor from standby mode, you can move the mouse or press any key on the keyboard. If this doesn't work, pressing the power button will wake up the computer. Monitors will also wake up from standby mode when they detect a video signal from the computer. If the monitor does not wake up, ensure that the computer is not in standby or sleep mode.
Some people prefer to turn off their monitors completely when they are not in use, especially if they won't be using them for a while. This can be more energy-efficient, although modern eco-friendly monitors use very little power in standby mode. Additionally, some people find that their monitors don't turn on reliably after being turned off, so they prefer to leave them in standby mode to ensure they turn on when needed.
If a monitor continues to enter standby mode when you don't want it to, you can change the power and sleep settings. In Windows, go to Settings > System > Power & Sleep to adjust the length of time before the monitor turns off.

Waking a monitor from sleep mode
Sleep mode is a power-saving state that stops all actions on a computer. Any open documents and applications are moved to the system memory (RAM), and the computer enters a low-power state. This is similar to pausing a movie on a DVD player. The computer is still powered on but uses less power. Devices such as monitors also use sleep or standby mode to reduce power consumption.
- Move the mouse or press any key on the keyboard: This is usually the first step to wake up a monitor from sleep mode. Simply moving the mouse or pressing any key should bring the monitor back to its normal, full-power operation within a few seconds.
- Press the power button: If moving the mouse or pressing keys doesn't work, try pressing the power button on the computer. This should wake up the computer and, subsequently, the monitor.
- Check the video signal and cable connection: If the monitor does not wake up, ensure that the computer is not in sleep or hibernate mode. Check if the monitor is receiving a video signal from the computer. If not, verify the video cable connection. Disconnect and reconnect the video cable, and restart the computer if necessary.
- Update graphics drivers and power settings: If the issue persists, try updating your graphics drivers by downloading the latest drivers from your GPU manufacturer's website. Additionally, check your power plan settings, especially the "Turn off the display" and "Put the computer to sleep" options. Adjust these settings to match your usage preferences.
- Change standby and sleep settings: If your monitor continues to enter standby mode frequently, you may need to adjust the power and sleep settings. Refer to your monitor's user guide or support articles for specific instructions on troubleshooting sleep and standby issues.
By following these steps, you should be able to successfully wake up a monitor from sleep mode and resume your normal computer operations.

Monitor performance
From a performance perspective, sleep mode essentially powers down the monitor, causing the panel to become unlit. This state is similar to turning the monitor off, with the main difference being that sleep mode retains open documents and applications in system memory (RAM). For users seeking to optimise performance, it may be preferable to manually turn off the monitor when not in use, especially if the monitor experiences issues with sleep mode or has difficulty waking up from it.
The sleep feature can also impact monitor longevity. While modern eco-friendly monitors draw minimal power in sleep mode, typically around 4 watts, it still requires some power to monitor the on/off switch. Over time, this can contribute to cumulative wear and tear on the monitor's components. To maximise the lifespan of the monitor, it may be advisable to turn it off completely when not in use for extended periods.
However, it's worth noting that some users have reported issues with turning their monitors off frequently. In certain cases, monitors may not turn on reliably when frequently powered off and on. This can create an inconvenience, especially when the computer is regularly used. Sleep mode can be a convenient solution in such cases, ensuring the monitor is ready for use whenever the computer is powered on.
Ultimately, the decision to use the sleep feature depends on individual preferences and priorities. Those seeking optimal performance and longevity may prefer turning off their monitors, while others may favour the convenience and power savings offered by sleep mode. Customising power settings can help tailor the monitor's behaviour to specific needs, allowing users to strike a balance between performance, power efficiency, and personal convenience.
