I recently purchased a Raspberry Pi 4 basic starter kit with aluminum case (Amazon Link). I am a completely new Raspberry Pi and Linux user, but am really enjoying it so far. The one question I have is regarding the LED status lights on the Pi. I have a USB keyboard, mouse, HDMI display, and the provided power supply plugged into the Pi, and nothing more. Yet consistently, whenever I turn it on, the two LED status lights are solid red, and not any other color (no flashing or anything else, just solid red). Here is a picture:

Oddly, however, the system still boots fine, I am able to use all my peripherals, and don't seem to have any useability issues with the system (I'm literally typing this post on my Pi4 right now). What could be causing this? From initial reading it seems like the the red color is not normal? How can I fix this issue, or even begin to troubleshoot?
Any advice would be greatly appreciated.
Thanks in advance!
