I have a "MSI GT680R-008US Notebook Intel Core i7 2630QM(2.00GHz) 15.6" 8GB Memory 1TB HDD 7200rpm DVD Super Multi NVIDIA GeForce GTX 460M", and the power jack has stopped working. Doing a bit of research, I've read that you may be able to replace this for not that much (?), although it might come down to buying a new motherboard. My question is if I do need a new motherboard, how much would this cost and would it be worth it to replace in this laptop. I purchased the laptop in May for around $1400 (I live in Canada).
