Bolt circuit board not working

I got my Bolt IOT kit on Saturday.Today that means on Monday I tried to power it.As shown in vedios after giving power led should blink.But no led blinked when I power my board.

Please tell me what would be the reason.I tried with charger adapter,power bank and laptop too,but nothing worked.


What is the behavior of the Blue LED immediately after powering on the device?

Does it blink once? If possible share a video of the behavior of the device via google drive.

We shall replace the device if found faulty.
