NAS Won't Power On: Pre-RMA Diagnostic Checklist
Work through these power adapter, outlet, and PSU tests before you assume your NAS is dead and start the return…
Your NAS should just work, until the day it does not. This is where we tackle the frustrating stuff: a Synology that will not boot, a QNAP stuck on a blue light, blinking status LEDs, beeping alarms, and units that drop off the network for no clear reason. Every guide here walks through the symptom first, then the likely causes in order of probability, so you fix the real problem instead of guessing. We cover Synology, QNAP, TrueNAS, Unraid, ASUSTOR, and TerraMaster, with steps written for people who did not build the thing themselves. Expect plain language, real error messages, and the small checks that solve most problems before you ever open a support ticket.
