Microcontroller circuit diagram

I have a DC to DC boost converter circuit to charge a laptop through the car cigarette receptacle

input: 12v

output: 19v

power: 65W

I need to add a microcontroller to the circuit which will display the state of battery of the laptop either with a small display screen. If the battery of the laptop is less it should automatically start charging the laptop and if it is full it should automatically stop.

Then I need the design to be made into PCB layout using ULTIBOARD on the software 'MULTISIM'.

Skills: Electrical Engineering, Electronics, LabVIEW, Matlab and Mathematica, Microcontroller
