Macbook pro, 2.5 ghz , 4 gb ram (bought in June) After the install of snow leopard, and a full charge. My battery at 96% showed only 2:45 hours, over the past 30 minutes with little no usage n the laptop (other than letting it sit at the office and periodicaly checking battery) I am seeing 81% charge and 2:05 on the charge. The screen is dimmed, display sleep is set to 5 mins, computer sleep to 15.... Anyone else seeing this? Health on my battery shows 97%, 67 cycles.
