Edison does not power up with a wall adapter but with usb does

Hi guys, this is my first time here, so hello !

I got recently a brand new Edison and it was working perfectly, using the USB communication and a wall adapter to power up (9VDC 850mA). After a shutdown that I did when setting the SSH, it stopped to power up using the wall adapter, no lights on, no powering signals, nothing. I realized that my wall adapter was heating too much after this event and my suspicious is that something is in short (I hope not). I tried 2 more wall adapters unsuccessfully.

For while both USB ports are working and Edison still working also.

Right now I'm deep diving in the schematics to try find out what's going on: http://download.intel.com/support/edison/sb/edison_arduino_hvm_8_26.pdf http://download.intel.com/support/edison/sb/edison_arduino_hvm_8_26.pdf

If someone already faced anything like that before, please shed some light here.

Thank you.

Hello pajé,

According to your description, the internal voltage regulator is damaged. The USB power supply is connected after the voltage regulator, that's the reason why the board is still working when you power it through the USB port.

If you got the Edison recently, I highly recommend you to contact the place of purchase and explain the issue to them. Hopefully you are still under their warranty period. If you are out of their warranty period, you can submit a warranty ticket using the following form and the Warranty Team will contact you as soon as they receive the ticket: http://www.intel.com/support/mailform/maker/edisonwarrantyemail.htm Intel Support.

Regards,

Diego.
