I had a ds1515 pretty much do the same thing about 1 month ago called synology they put a charge on my card for like 799 until new one was received back did the rma and went smooth.
Synology ds1515 power supply problem.
Pressing the power button doesn t do anything.
After reading the item description and reviews i called synology technical support.
Like other reviewers i was about to buy this power supply for my ds1515 that suddenly died and would not turn on.
There are notable examples on the internet to test for and work around this common issue.
The other common problem is the power supply fails inside the unit.
But before i shipped the unit back to synology i tested the power supply and it was fine.
Search by spare part.
If warranty isn t an issue and you are comfortable taking apart computer hardware by all means try it.
Otherwise send it back to your place of purchase to get it repaired.
My ds1515 actually failed right before new years.
Select category a part denoted by the term of eol end of life refers to that it is obsolete and will be no longer provided by synology.
If you have a recent updated software release on your nas system your good to go.
Search by products or by spare part categories for replacement such as fan disk tray or a power supply for your synology products.
They are replacing my nas completely free of charge and did not give me any hassle at all.
My data is also fine.
