My NAS doesn't power on or boot. How can I fix this?

This article lists the most common reasons that a NAS won’t power on or boot. Use this article to troubleshoot your NAS and find a solution.

Before continuing, follow these steps:

1. Power off your NAS.

2. Remove all the drives, including M.2 SSDs installed internally or on a QM2 expansion card.

3. Disconnect all external USB devices from the NAS. If you have installed non-factory RAM, make sure to reinstall the original QNAP RAM modules that were shipped with the device.

4. Power on the NAS.

5. Check the errors below to see which one you are experiencing

Problems, Causes, and Solutions

Problem #1: The NAS does not power on.

Possible cause: Faulty power adapter or power supply

Check whether the LEDs on the front panel turn on after pressing the power button.

If none of the LEDs turn on, the power adapter or power supply of your NAS may be faulty. You can try plugging in the NAS to another power outlet to double-check.

Solution: Contact our Helpdesk or your QNAP reseller for warranty repair service. For out-of-warranty units, a replacement power adapter/power supply can be purchased at the QNAP accessories store.

Problem #2: The NAS does not pass the POST (Power-On Self-Test).

Check whether the NAS produces a short beep about 5 to 10 seconds after being powered on. If you don’t hear a beep, the system has failed to pass the power-on self-test. The most common cause of this is a faulty system board or faulty RAM.

Solution: Contact our Helpdesk or your QNAP reseller for warranty repair service.

Problem #3: Corrupted firmware image

Within five minutes after powering on your NAS, you should hear a long beep (about 1.5 seconds long). This indicates that the QTS operating system has finished booting.

The absence of a long beep may indicate that your NAS has a corrupted firmware image. This results in the NAS being unable to boot QTS.

This could be caused by the NAS being abruptly powered off during a firmware update.

Solution: Follow the firmware recovery procedure that is documented step-by-step in this guide. If recovering the firmware does not solve the issue, contact our Helpdesk for assistance.

Problem #4: Non-hardware issue

If you have followed all the above steps and you hear a long beep after five minutes, then your NAS hardware has booted successfully. However, if you still cannot access QTS when booting with disks inside the NAS, then there may be a QTS system partition error or configuration file error on the disks.

Solution: Contact our Helpdesk for further assistance and troubleshooting tips.
