To Sleep or to Shutdown your computer? What's the best choice for your machine?

The debate between Shutdown and Sleep mode is a heated one. Some argue that shutting down is safer, avoiding power wastage. However, many find the convenience of Sleep mode appealing, allowing instant access without waiting for boot-up. So, what's the best choice for your machine, Shutdown or Sleep? Let's find out.

What happens when we Sleep or Shutdown our machines?

Shutdown involves a coordinated operation between software and hardware. When you initiate a Shutdown command, all open programs receive a timed notification from the operating system to stop any file reading or writing before the system powers off.

The shutdown signal is then immediately sent to remaining devices and drivers, gradually cutting off power supply. However, this is under normal Shutdown. In some cases, if you force shutdown your computer or laptop by holding the power button, you risk corrupting running files and potentially damaging the hard drive.

In Sleep mode, it's like your machine taking a rest. All open files are stored in RAM (Random Access Memory) and operate at low power. Most software and other hardware are also disabled during this time. However, they quickly 'wake up' when you press any key or move the mouse, allowing the machine to 'wake up' and be ready to respond to your needs instantly.

How do Sleep and Shutdown modes differ?

As far as I know, there are 2 main differences between these 2 modes, Shutdown and Sleep.

Firstly, it's about startup time. When you put your machine in Sleep mode, it restarts very quickly, just a few seconds and the computer is ready for you to use. Additionally, because all tasks are saved in RAM, you can resume work immediately from where you left off.

With Shutdown mode, you'll need more time to restart your computer, especially if it's equipped with an HDD. Additionally, you need to save all your work and data before shutting down, or else you'll lose everything.

The second difference lies in power consumption between these modes. While there's a difference in power consumption between Shutdown and the computer being off compared to Sleep mode where the machine is at its lowest power state, according to Energy Star, we only save about 1 to 2 watts by shutting down the computer compared to putting it in Sleep mode.

What are the advantages of Sleeping and Shutting down your machine?

In my opinion, these two modes heavily depend on your usage needs and work nature. To make the most appropriate choice between Sleeping and Shutting down your machine. Let's explore some advantages of these two modes.

• Advantages of Shutting down

- Hardware responsiveness

This is considered one of the most debated factors in the Sleep vs. Shutdown topic. Previously, computer components were more prone to damage if the computer was turned on and off too frequently, especially with hard drives and thermal management.

However, nowadays these components have been greatly improved. Therefore, they can fully withstand both Sleep and Shutdown modes optimally. Although there is still a certain amount of wear from daily Shutdowns, I believe it is minimal and does not cause significant damage to your machine.

- Energy consumption

In Sleep mode, the machine consumes energy to keep files and open programs stored in RAM. This slightly increases power usage, which some may find wasteful when the machine is not in use during this 'sleep' period.

Conversely, in Shutdown mode, the machine seems to consume less energy. Oh, and remember, when you Shutdown, the computer still consumes some energy after turning off, it's not entirely energy-free.

- Startup time

Shutting down the machine is like giving the operating system a chance to clean up. Shutdown helps address system issues like errors, memory leaks, or unused network connections. Additionally, the Windows operating system also runs background updates, and one way to update is by requiring a system restart.

If you don't Shutdown (or restart) the machine, all these issues will snowball, decreasing performance and loading times for the machine.

- Surge in voltage

Although rare, voltage surges can damage your computer even when it's Shutdown or in Sleep mode.

The main damages include corrupted files, scratched hard drives, and data loss, with the worst-case scenario being your computer failing to boot up. Shutting down the machine reduces the risk of such damages to hardware components.

• Advantages of Sleeping

- Convenience and Speed of Use

If your computer is in Sleep mode, it can be quickly 'awakened' by touching the mouse or keyboard or pressing any key.

Starting up the machine from Shutdown requires waiting for boot-up and loading all necessary files (although we can now boot up faster thanks to SSDs). In my opinion, startup time is one of the advantages of Sleep mode. If you use your computer frequently throughout a long day, then shutting down and rebooting will consume a considerable amount of your time.

- Background Maintenance Programs

Our computers often run important background maintenance programs like virus scans, disk cleanup, or system backups. These activities typically occur during the 'afternoon hours' (while the computer is in Sleep mode).

Therefore, shutting down the computer may hinder essential background maintenance programs, making your computer more susceptible to malware than Sleep mode.

Choosing Between Sleep and Shutdown: What's Best?

Based on what I've mentioned earlier, the best choice is to Shutdown the computer if it won't be used for a long period (like overnight) and to keep it in Sleep mode during sunny hours (daytime usage). For instance, if you're working continuously on your laptop all day and need a short break to grab lunch, it's best to leave the machine in Sleep mode. Shutting down is preferable when you've completed your tasks and won't be using the laptop for an extended period ahead.

In general, in specific cases, it depends on your computer usage needs to decide whether to Shutdown or Sleep. Personally, I believe we should utilize both modes simultaneously during computer usage to optimize their performance for your work and study needs.
