I took apart my laptop to fix an overheating issue. When I had it apart I noticed a extra connector on the bottom side of the motherboard next to the SATA. I looked in the toshiba maintenance manual and it referred to a SSD 1.8. I figured it was a mSATA so I bout one and took the thing apart again only to find that it wouldn't fit. It did fit in the wireless slot but not next to the SATA. A pic can be found here. http://s18.postimg.org/6nbvxanax/photo.jpg
No, it's not the power connector. I think it's a SATA connector. But it doesn't have a lot of room. here is a better pic the connector is in the lower left of the screen.
