I received the board 9-29-21 (didn't have time to do anything with it until yesterday, 10/3/21) Order ID: 2664740-8934443150
I'm having the same problem(s) as
tymerones (viewtopic.php?f=62&t=183748&p=892540&hi ... M4#p892540) and
AdamTheGreat viewtopic.php?f=62&t=183701
After reading through their threads I suspect the board is bad, but I'm willing to do some additional troubleshooting.
I've tried three USB-C cables, including one known-good data cable (tested with my phone, transferring data in both directions immediately prior to the attempt to connect the Matrix), three computers, including trying both the Arduino IDE and Mu/CircuitPython. I successfully tested the Arduino IDE with an known-good Arduino Uno board connected to the same USB ports as I've tried to connect the Matrix Portal (via USB A-B cable, but as mentioned I'm using a known-good USB-C data cable).
On all three computers, Windows doesn't detect the MatrixPortal M4 (the board doesn't have a port assignment and there's no audio cue from Windows when I plug or unplug the board), there's no communication between the MatrixPortal M4 and Arduino IDE, the board's reset button does nothing whether connected to the computer or a 5V supply, nor does connecting the RST pin to GND on the board. The NeoPixel never lights, only the 5V & 3.3V LEDs light.
I've made sure that the Arduino IDE on all three computers I've tried has had the SAMD board tools from Arduino and Adafruit installed as directed. The installation for the Adafruit packages resulted in an error: . . . packages\adafruit\hardware\samd\1.7.5\post_install.bat not trusted so I went in and ran the post_install.bat as Administrator, which didn't throw an error, then rebooted and tried again with no success.

Re: Matrix Portal M4 not connecting (Windows, Arduino
Just to double check your reset button tests - did you try double pressing reset to put the board in bootloader mode?

Yes - I've tried pressing, double pressing, slowly double pressing, quickly double pressing, and so on. The power LEDs never even flickered, and the neopixel stayed off.adafruit_support_carter wrote:Just to double check your reset button tests - did you try double pressing reset to put the board in bootloader mode?

Re: Matrix Portal M4 not connecting (Windows, Arduino
This sounds different than behavior described in first post. Before, the power LEDs were at least coming on?The power LEDs never even flickered, and the neopixel stayed off.
Now those are not even lighting up? They have nothing to do with the reset button. They are simply power indicators, so should come on with just power.The NeoPixel never lights, only the 5V & 3.3V LEDs light.

Re: Matrix Portal M4 not connecting (Windows, Arduino
Sorry for not communicating clearly. The first post was correctly worded: The 5V and 3.3V LEDs are lit and steady as long as the board has power.adafruit_support_carter wrote:This sounds different than behavior described in first post.

I was trying to say that they never turn off, not that they don't come on.

Re: Matrix Portal M4 not connecting (Windows, Arduino
Ah, OK. Thanks for clarifying. Let's replace it. If you still have the bag/bubble wrap the Matrix Portal came in with the white label sticker on it, can you please post a photo of the sticker. It has an Adafruit logo and some bar codes and stuff.
For the replacement, send an email to [email protected] with a link to this thread and your order number and they can send you another Matrix Portal.

Yep, that's the sticker. Thank you very much for the photo!
