Should I worry that my battery Cycle Count is 1215?

Solution 1:

All laptop batteries age, and wither, and die, and it's this that affects the continued viability of the computer. You've had that one for over 5 years, and it is only holding 60% of its original capacity.

If you mainly intend to use it plugged in, then then it's not really a problem, though the battery will continue to degrade. The computer does need a working battery to function properly: without it, it will throttle the CPU. There is a teeny-tiny risk that as it continues to degrade, it could catch fire or explode, (though presumably, if it's not holding much energy...:lol: )

My advice would be to take it to an Apple Store. Apple will replace the battery for around $200, I think. You will then have a laptop that's 'as good as new', which will work reliably for another 5 years or so, either for you, or your Father.
