Smoke is a real bad sign and it's highly unlikely the laptop itself can be salvaged, however, you can probably still get all your information off of it when you do get a replacement. If you're unfamiliar with how to remove the hard drive and hook it up to an enclosure to pull the info off yourself, take the laptop to a specialist (basically any computer repair shop should be able to do this easily) and ask them to recover the information. They'll charge you for it, though, so whether you want to do that or not depends on how important that information is to you.
