my mac air does not turn on

though i have the mac since christmas ,i only been learning about mac for the last two months , i am just starting to appreciate the difference ,but yesterday after verifying battery charge was at 97% I shut it down using the aple icon ,turning the modem off and accepting shut down . about five hour latter the power swithch does nothing at all .I read the previous entries on this problem and there is a few entries from someone that had a similar problem but i observed that he did not have a mac air . never the less , there is a lot of coments and i tried them all , at same stage there is a way of force quiting that i tried and then noticed tha the fans are working ,they switched of pressing power for ten seconds ,and after trying the other steps unsuccefully i did the restore sugested specific for mac air books with non removable batteries ( tried about 3 times) but nothing happens . i still can'not turn it on . this is very fustrating . i hope someone can give me advise before i take it to a shop or repair person , i have only joined today because unfortuntelly i need your support , but is very good to know there is people out there kind and generous with their time . thank you all before hand ,just for being out there ,together ,in times to come any kind ok global community will strengten our human condition on this planet of ours,
