yellow lightning and CPU
-
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.

@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? -
@rikko14 it happens
-
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.
-
@bkeyport I have a Pi 4 B.
-
@rikko14 pi4 requires the most power
-
@sdetweil
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.

@rikko14 2A is close. I bought some 5A supplies
