battery problem and possibility of change
hi, my MacBook is the late 2009 one, the capacity of the battery is like 89% ( coconut battery), i saw recently that a new MacBook has a battery long lasting, something like 10 hours ( againsti 6 like mine) do you know if its possible to change with the better one ? is really the battery to be more powerful or an improved management of the power ? please let me know, im' really wondering if to change it!
Is this a good question?
