Using a MACBOOK with 10.5 OS and having battery problems. For the past 3-4 months I have noted that I can get no longer then 1-2 hours using only battery power, although it indicates I actually start with 100%. At the same time, I noted that the fan has been running continuesly when ever the computer is ON regardless of being charged or not plugged in while operating.
I felt I needed a new battery and have gotten one and it's installed. I continue to have the same problem even with a brand new battery.
Is there some procedure I have omitted in installing the new battery, or is there a problem with the computer and I didn't really need a new battery?? I charged the new battery to 100% and then used it without the cord to bring it down to 1-2%. It has been recharged back to 100% twice, but I still am unable to get more then 1-2 hours out of the full charge.
Suggestions would be most welcome. Thanks
