Battery won't charge to 100%. Optimised battery charging has been turned off
Orange charging light stays on (MagSafe connection to apple-supplied charger) but won't charge to 100%.
Is there a problem with my mac and/or charger?
If I did check the optimised battery charging option then it would only charge to 80% if I generally only used it on the charger and not via battery.
