Hey guys I have a really weird issue with my macbook air ultimate 2010. I have restored it a few times from time machine backups due to some weird bootcamp ereors and i am not sure what happend but now with a full charge i get 2:10 battery remaining? So I am figuring somewhere in the restore something went wrong and I just bought lion. My question is if I upgrade to Lion will that replace my OS to where that weird bug is gone or do I need to restore again? THanks guys in advance
