Yeah i had the same problem and got the newertech one - WAYYYY better quality if u ask me - never had a problem with it, and i dont miss the charging light. i am very interested in buying one of THEIR replacement batteries. Anyone tried them? Anyone know if its possible to overclock the processor on my Powerbook G4 867 /640 or at least allow it to use much more ram (like 2gb instead of 640 mb), i need it for some heavy video work and i cant afford a new computer right now.
