Framework 13 battery light flashing orange, red, and green when charging and booting from 0%

(Laptop 13, 13th gen Intel base model, bios version 3.04 (I think))

My laptop ran out of battery yesterday, so I tried to charge it. I use a 45W charger. I plugged in the laptop and turned it on, but it turned off after ~5 seconds. The laptop’s LED by the charger port started blinking green, and then it started to blink red and orange repeatedly. I tried unplugging and plugging back in the charger and repeating this, but the laptop still had the same blinking pattern. This eventually started happening even before I was able to turn on the laptop. I left the laptop alone for a minute plugged in, and everything seemed to work normally.

What does this mean? Is there a table/guide for these things?
