Answer : You can download the free hwinfo32 app and run it. Look under motherboard, and the SATA ports that are live and supported will be listed. If there is a label next to the solder ports (like "SATA 1, SATA 2, etc.), then you can see if that port is active. If it is, you are good to go (as long as you are as good at soldering as you think you are). I disagree with the naysayers above. While SATA connectors themselves are extremely cheap, many laptop manufacturers contract out the assembly of their motherboards, and they are charged by the component or by the solder joint. In those terms the cost of the connector is less trivial, and it makes a bit more sense to not include it. Motherboard layout is expensive enough that computer companies will use the same layout for multiple versions of a board, just without adding all the components to all of them, so those motherboard traces almost certainly lead to the SATA chip. There's no reason in principle this wouldn...
