Gamepad and Light bolt problem (Rpi3)

kkostis

Hello,
Today I encountered a strange problem
I have a Raspberry Pi 3 Model B with Retropie installed and updated. I am using it at least for 2 months without any problems. But today i noticed that the yellow lighting bolt is ALWAYS ON when i have my logitech gamepad connected. The power supply is ok. When i disconnect it bolt dissapears and game runs smooth. When I reconnect it bolt is on again.
It seems weird to me. Is there someone who encountered this problem also? And what does it mean? I cannot understand. Any advice would be helpful.
Thanks in advance.

The power supply is ok.

It's probably not broken or anything, but it's very likely that it doesn't meet the required specifications.

I forgot to mention that the red led blinks
I say that the power supply is ok because i use this supply with no problems or bolts for a long time.
Its only today this happened.

What are the specifications (volts/amps)?

@mediamogul
5v/2.1 A

It's just a bit under requirements, but it shouldn't be enough to struggle with just one controller. Do you have anything else connected?

kkostis

i have also connected a wireless mouse/keyboard. but the problem appears only in gamepad

@kkostis

If you disconnect the keyboard and mouse, are you then able to use the gamepad without the power issue?

kkostis

no im not able

Assuming that the power supply simply isn't failing, that gamepad must be drawing a lot of power. It may be necessary to get a power supply that is at or even above the normal amperage specs, like 3 Amps. What kind of gamepad is it?

kkostis

logitech dual action
But all the time i was using it it was working well.
May some updates caused that problem?

Sometimes it can happen that a system update will tip you over the edge of what a power supply can handle. If that is in fact the case here, then you were probably at the borderline all along.
