What it means
On the ThinkPad X1 Carbon 13th Gen, three amber and three white blinks of the charge LED mean 0288, "Computer display error". Lenovo says to reconnect the display cable on both the system board side and the display side (service provider only) and check the LCD panel; if that does not work, connect an external display (customer or service provider). If the external display works, the LCD panel is replaced; if not, the system board. That test is what separates panel from board: the code alone does not.
