It is common for people to leave their computers on for long periods, leading to the system entering a sleep mode. Although this is common practice, there are many who are unaware of what happens to their computer during this state.
When a computer is left suspended, it enters a low-power state known as “sleep mode” or “standby mode.” During this state, the operating system and running programs are stored in RAM, and most computer components, such as the display and hard drives, are turned off to save power.
In sleep mode, the computer is in standby mode, this allows the computer to be quickly restored to the state it was in before going to sleep when you wake it up, and the user can continue working from where they left off without rebooting the system or open the programs again.

Using this mode is generally safe and offers benefits. However, there are some potential risks associated with this state:
Loss of data: If a blackout occurs or the power supply is disconnected while the computer is asleep, there is a risk of losing unsaved data.
Stability issues – In some cases, it can cause stability issues in the operating system. This can result in crashes, unexpected reboots, or unusual behavior when resuming from suspend. These problems may be caused by incompatible drivers or software, and may require solutions such as driver updates or adjustments to system settings.
Residual power consumption: Although sleep mode consumes less power than when the computer is fully operational, there is still residual power consumption to maintain data in RAM.
This may be relevant if the device is left asleep for extended periods without an external power source, such as on battery-reliant laptops, cell phones, or tablets. If it runs out completely, the computer can shut down and lose the data in RAM.
When the computer is left on without activity, the device enters a sleep state.
It is important to note that sleep mode is different from hibernation. In this mode, system data is saved to the hard drive instead of RAM. This allows for even greater energy savings, since the computer is completely turned off.
Using hibernation mode instead of shutting down the computer completely has several benefits. Some of them are mentioned below:
Power Saver: The computer shuts down completely and consumes a minimal amount of power while in this state. This is especially useful when you need to leave your computer idle for long periods of time, such as overnight or when it won’t be used for several hours.

Working state maintenance: The computer saves all the data and working state in the hard disk. This means that when you turn it back on, it restores you exactly where you left off, with all programs and documents open as they were. This is convenient and saves time, since there is no need to open the programs again and recover the previous work.
System integrity protection: By shutting down the device completely, there is a risk of data loss or system damage if a sudden power outage occurs. With hibernation, data is safely stored on the hard drive, providing an extra layer of protection and preventing data loss in the event of an unexpected event.
Faster power on: Compared to a cold start after powering down completely, this mode offers a faster start. Upon reactivation, the system quickly restores the previous working state, allowing the user to continue with their tasks without having to wait for all programs and files to load again.
