Hi, i am using MBP 13 inch Mid 2012. Having it since early 2013. Last year, due to hard disk problem, ive changed to SSD 512GB. Running smoothly until recently, whenever I move the laptop, it will freeze and restart. Sometimes, blue/white horizontal/vertical lines appear on the screen. Brought to third party shop, and they said its logic board prob. May I know how much is the usual cost to repair/replace the logic board?
