Reading Time: 3 minutes

Windows 10 has various types of sleep mode, one of which is Modern Standby (modern standby). It is not available for all laptops and desktops that can work on the system. It is limited to certain equipment. There is not even a list on the official Microsoft website, on what type of equipment it is available, but a simple command will tell you whether you can enable it on your system or not.

Different type of sleep modes in Windows

S0: The Modern Standby mode is listed as “S0 Low Power Idle”. All devices are running at a very low power mode.

S1: The CPU is still on, but it won’t execute any instructions. The RAM is refreshed periodically. The power consumption is a little more and this phase is no longer used in any Windows compatible device.

S2: Just like S1, but this mode consumes less power than S1. Just like S1, S2 sleep mode is no longer supported in any Windows compatible device.

S3: This is the mode that we usually call as Standby mode. The CPU is turned off and RAM is refreshed periodically, but it consumes very less power.

S4: This mode is called Hibernation mode. All the devices go to sleep and powered off. The contents inside the system memory are stored inside a temporary file which is saved inside the hard disk.

S5: Everything is turned off. Basically same as that of shutting down the computer.

When you have a normal S3 standby mode, your processor shuts down, data is reset to memory, and you have RAM that consumes only the minimum amount of power needed to prevent data loss.

In Modern Standby S0 mode, the processor does not turn off and consumes very little power. Most services and processes in Windows 10 run in this mode. This mode can also run the processes or run tools (if scheduled). This may cause the battery to discharge quickly.

Why put the computer in Modern Standby Mode

Some users want the background activities to continue even when the computer is in standby mode. Here are some cases when the user wants Modern Standby mode

  • User has scheduled to send mails during sleeping hours from an email client like Outlook.
  • User want all emails and social media updates to be downloaded even when the device is in standby.
  • Some users like to run maintenance tools and windows updates in standby mode so it won’t consume the productive hours of the device.
  • Some users want their machine to wake up quickly as soon as it is turned on. (Modern Standby Mode wakes up in 2-3 secs, while normal standby mode takes around 4 to 15 secs and S4 hibernation takes longer than this based on the amount of saved data stored inside hard disk and hardware configuration.)
