      Hello ,
      What does the yellow lightning at the top of my screen mean?
      on my module at the bottom left I see that the CPU is used a lot, how can I reduce its use?

        @rikko14 Yellow lightning in the upper right corner is power problems. You’re not suppling enough power to the Pi.

        The "E" in "Javascript" stands for "Easy"

          @bkeyport Thank you for your reply.
          However I use the power supply delivered with my Pi … (Input 100-240 ~ 50 / 60Hz 0.6A, Output: 5V3000mA, 9V2000mA, 12V1500mA) And it seems to me that when I installed the Pi before the modules that was not displayed. the Pi is plugged into a power strip with only the 24 "screen and the 12V power supply for small speakers.
          What do you recommend ? Is the original power supply defective?

              I’m assuming you have a Pi 3 or older, right?

              I would power the pi via the GPIO 5V to get around the USB spec for MicroUSB that isn’t enough for the Pi.

                    here is the power supply that came with the kit that I bought on Aliexpress.
                    I changed the power supply to a SMASUNG 5V2A and I no longer have this yellow lightning.
