Here's a funny, kinda confusing thing. My Macbook Pro booklet 'Everything Mac' WARNS: 'The battery in your Macbook can be replaced only by and Apple Authorized Service Provider, or an Apple Retail Store' (page 31). I was even warned, 'mess with the battery and you lose guarantee rights'. OK - I wont touch the battery, but, hey Mr Apple, how do I clean my screen? So I look it up on my Apple sanctioned 'Macbook pro users guide' in pdf: 'To clean your MacBook Pro screen, do the following: Shut down your MacBook Pro, unplug the power adapter, and REMOVE the battery.' (page 109) Appart from the contradicting information, we have to remove the battery to clean our screen?!?
