Still using my M6300's for all kinds of applications. Samsung Pro ssd and win 7 make it a viable performer for its current use. I Splashed coffee at top of keyboard on my favorite M6300. Just enough that it looks like I have to replace the motherboard. Found one on newegg that states its new for $104.00. Seems reasonable to get it back in use. Is JM679 the only one used for M6300's? Will I have to transfer my m1600 graphics over to the new board?
