The keyboard circuit board is not big, no screws fixed, can also be directly taken down. There are not too many components on the circuit board, only a few electrical routes are connected. There are 3 LEDs on the other side of the board, which is the "Num look", "Caps lock" and "Seroll lock" LEDs in the upper-right corner of your keyboard.
