MacBook Air

My 5 month old MacBook Air died on me today! It would not boot up and was bleeping at me. The chap at the shop believes that it's a hardware problem, so I had to leave it with him to replace whatever bits need replacing, thank god it's still under warranty. This is the second time it's been in for repairs, the last time it was in early June to replace the screen. My jinx with electronic equipment strikes again!!!
