After watching your keyboard replacement video I have a question I hope you can answer.
Well my sons 4 month old MacBook Pro 13" took on water the other day. It seems to be working fine after drying out. The water was spilled on the keyboard. We are happy it is working but if now his extra 2 year applecare is gone I was thinking he should apply for a refund since it can never be serviced if sensors are tripped.
I found this website showing where 4 of them are:http://www.appleinsider.com/articles/08/10/15/inside_the_new_macbooks_lsi_battery_hd_and_ram.html
And the 4 in the first picture are fine. But my question is this, in the second picture looks like there are 4 more under the keyboard. But the picture says MacBook Pro 15". So does the 13" only have the 4 or is there 8?
