Yes, the leading cause of failure like you describe is a bad supply. Using one that does not supply enough current will result in the device not powering up. Also, your description of the model is confusing. You say that it is an M1000 with the ports in the back. The M1001 has the ports on the back. The M1000 uses a completely different supply than the M1001. What does the factory power supply list for voltage and current?
