Query: DO NOT BUY THIS!!! Not even worth the cheap price!

We purchase 3 of these for my wife and my PowerBook G4 Aluminum and after a few weeks, one of them died. Also, none of them wake the computers up from sleep after the battery has completely drained - we have to plug into my wife's remaining Apple power adapter. I didn't return because I didn't even feel like it would be worth the shipping for my time to deal with these.Pay the extra $15 to $20 to get an Apple power adapter - you definitely get what you pay for!
