After going to 3 other places in the Randwick area and hearing about prices that started at $100 even if they couldn't find the fault AND would still require me to leave my laptop there till the next day, I tried LappyLuke. Not only did he figure out what was wrong within minutes of walking in the door, but also fixed it on the spot. A total time of less then 10 minutes of which he charged me and equivalent amount.
Cheap, fast, and a nice guy. Highly recommend
