Fixing a Synology Blue Light That Blinks
Proceed from the simplest to the most complex troubleshooting methods. You will often be able to resolve the issue without the requirement for data recovery or maintenance.
1. Shut down and restart safely.
Occasionally, the NAS just doesn’t initialize correctly.
- Holding down the power knob for five to ten seconds will cause it to switch off.
- For two minutes, unplug the power cord.
- Restart the NAS and reconnect the power.
- The problem is fixed if the blinking stops and turns solid blue.
2. Examine the cables and power supply.
One typical cause is unstable electrical power.
- Make sure the power adapter is the genuine Synology model.
- Try using a different power source.
- Steer clear of power strips that have surge problems.
5. Examine the RAM installed.
Startup may be hampered by faulty or malfunctioning memory.
- After the factory-installed RAM module, remove all other RAM modules.
- To test, restart the NAS.
- The extra RAM is probably the problem if it boots.
- The module itself can be faulty if even the default RAM is unable to boot.
6. Reinstall DSM while retaining data
Reinstalling DSM can resolve the problem if the operating system is corrupted but the hard disks are in good condition.
- Open Synology Web Assistant in a web browser.
- To reinstall DSM without formatting drives, adhere to the instructions.
- Your applications and data are still intact.
7. Reset the System as a Last Resort

- Without removing shared folders, boot functionality can be restored with a reset.
- This is also helpful if you need to reset the settings on your Synology router, but keep in mind that you shouldn’t start troubleshooting with a reset.
