Click on the black upper Apple symbol and select 'About This Mac', more info button.

Edit: My bad.

Yeah, but it won't boot.

Try sticking your serial number in here : https://selfsolve.apple.com

2009 MacBook air not booting. Blank screen. Sometimes Apple logo comes up. Nothing happening now. Installed Yosemite.problem ever since I installed. Serial no: W80380FU9A7. Any help would be appreciated!

I know it's too late to really help at the moment, but I'd like to present a concept to you:

THIS is why a savvy Mac user ALWAYS has at his/her disposal a SECOND bootable drive.

It can be either a bootable backup created with CarbonCopyCloner or SuperDuper, or a separately-created drive with a copy of the OS on it.

Just connect, and go. This can help you recover from drive hardware/software problems. (Aside, if it's some kind of hardware failure with the Mac itself, it can't "get by" that...)

Again, I know this doesn't help at the moment, but it's something you should consider once you get things together again...

Thanks for the reply...I don't have either...is there anything else I can do?

Maybe worth being patient?

Otherwise it's probably a trip to the Apple store...
