SL failed my battery status!
I bought a used Macbook 2.1 GHz with Leopard (10.5). Battery condition was good, according to the About My Mac Information button. I couldn't complain about battery endurance when I was using it. Wanting to get a more current OS, I formatted the drive and did a clean install of Snow Leopard. Battery performance is still unchanged, but now I get a Replace Battery when I look up battery condition. Why the change? Is 10.6 more demanding on battery life?
Is this a good question?
