General: What stops my Synology NAS from entering System Hibernation?
Last Updated 8 years ago
System Hibernation is only supported on DS213+ and D413. When System Hibernation is enabled, your Synology NAS will enter System Hibernation mode 60 seconds after HDD Hibernation, massively reducing power consumption.
There are three power-saving modes: HDD Hibernation, HDD Deep Sleep, and System Hibernation. Below is the mechanism of entering these power-saving modes and the steps of entering each mode will be briefly introduced.
When System Hibernation is enabled:
Any SMB/CIFS broadcasting packets may prevent your Synology NAS from entering System Hibernation, including any Windows file browsers operating in the network. Should you wish to ignore CIFS broadcasting packets on entering System Hibernation, please select Ignore broadcasting packets from Windows Explorer. Please be aware that once this option is selected, SMB/CIFS packets cannot be used to exit System Hibernation. Attaching any USB device will also prevent the server from entering System Hibernation.
There are three power-saving modes: HDD Hibernation, HDD Deep Sleep, and System Hibernation. Below is the mechanism of entering these power-saving modes and the steps of entering each mode will be briefly introduced.
When System Hibernation is enabled:
- Your Synology NAS enters HDD Hibernation first and continues monitoring network packets.
- If no unicast packets are received by your Synology NAS for two minutes, then your Synology NAS will enter System Hibernation.
- If any unicast packets are received by your Synology NAS within two minutes, then your Synology NAS will remain in HDD Hibernation and continue monitoring network packets for another two minutes.
- Once the total delay time exceeds the original hibernation time, your Synology NAS will enter HDD Deep Sleep mode.
Any SMB/CIFS broadcasting packets may prevent your Synology NAS from entering System Hibernation, including any Windows file browsers operating in the network. Should you wish to ignore CIFS broadcasting packets on entering System Hibernation, please select Ignore broadcasting packets from Windows Explorer. Please be aware that once this option is selected, SMB/CIFS packets cannot be used to exit System Hibernation. Attaching any USB device will also prevent the server from entering System Hibernation.
