Alright, I'll admit it's stupid, but I spilled around 2 teaspoons of oil on my keyboard, I was able to get up around 1 teaspoon with a paper towel, but the rest seeped in. Lucky for me, the keyboard still works great, but the backlight is very weird. In the middle part, it is good, but in the left and right parts, it is much dimmer than it should be. (You know if you equally divide the keyboard into three sections). What have I damaged? If I want to replace something, should it be the keyboard or the top case?
