[QUOTE="Doug b, post: 949770, member: 59143"] Is there actually proof of this ? I have more than enough products which when are finished charging, will automatically stop charging and the charge light will turn off. But I doubt this is true of the MB or MBP given the fact that when the computer is turned on, it is draining the battery regardless of what it's doing, so the battery is never truly full. Try filling the battery and then unplug it. Test to see how long it takes for that light to turn red again.. Probably not long at all. Other 'proof' to contradict this is that the port and the entire side near the charger is always hot when it's plugged in. Unplug it, and see how much cooler it gets within no time at all. If there were no charge going through it, it wouldn't be as hot. Doug [/QUOTE]
