The way it works is easy, it takes power from the laptop itself by a small inverter lead that runs from the motherboard of the laptop, sometimes it is a direct lead on it’s own, different times this lead will be connected into the inverter through the LCD cable (the lead that runs from the motherboard to the back of the screen itself), giving the screen its visual display.
At one finish of the inverter, usually the left end, the lead that offers it power is plugged into a tiny white socket and from the other end, sometimes the right aspect, the backlight lead from the screen is plugged into another white socket. The backlight could be a terribly tiny, thin, long, very delicate light bulb that runs along the very bottom or sometimes the side of the screen.

This inverter is also compatible with the IBM T21, and T20 all 3 laptops as an entire are essentially the identical except the processor.
