Question Satellite A665-s6086 motherboard

[doughullo]

How can I find the correct motherboard model number for my Toshiba Satellite A655-s6086. Seems like there are so many.

If you have the box still, it may say on the box. You may also be able to find out from the serial number (I'm not sure if Toshiba have the option to check though). BIOS may also say, but again I am not sure.
