Are you sure the right power supply is plugged in?• DC input voltage: +5V DC at 2.0A max.• Power consumption: 5W• Switching type (100-240V) automatic• Power adapter: 100-240V - 50-60 Hz (26-34 VA) AC input, 1.8 m cord
If it is less than 2A then it could have issues - an underpowered supply is bad for electronics.
Otherwise, maybe the power supply is failing.
Looks like the supply has twice the current required for the stated 5 watts used.
