Power failure after two weeks?

by dexterduolaameng on Mon Aug 13, 2012 6:48 pm

I started to test my new BeagleBone two weeks ago. Everything seems working.
But yesterday when I plug in the 5V supply (got from Adafruit:, the power led just flashed once and turned off immediately, and the system did not boot.
I tried the usb power supply many times too. No luck.

I tried to measure SYS_5V with external 5V supply connected. There is no output.
So is this a PMIC failure? What should I do?

Any suggestion is deeply appreciated...

I have the same issue. I got 2 last week and plugged one just to burn it in. It's been running fine until today when I decided I wanna doing something with it. So I plugged in USB mouse and it just died. Now, when I plug in the 5V supply (also from Adafruit), the power LED just blinks.

How do I go about with RMA?

You'll probably want the same link as above:

There's an RMA link on the page, and they'll have more information about troubleshooting the board to confirm the nature of the failure, or possibly get it working again so you don't have to wait for a new one.
When you void a product warranty, you give up your right to sue the manufacturer if something goes wrong and accept full responsibility for whatever happens next. And then you truly own the product.
