This is for the early MBP CD version. I will have to find the apple support page again explaining about MBP battery replacements...if anyone has the link, I'd appreciate it. Basic background...MBP was purchased around July/Aug of 2006..so it's been a little over two years. In the beginning, battery life was great..but now it's horrible. It probably lasts less than an hour just surfing the internet or working on a Word document with all the settings for a longer battery life. I have calibrated it recently and have installed the battery update. The stats are: Model Information: Serial Number: Sony-ASMB012-34dd-c46b Manufacturer: Sony Device name: ASMB012 Pack Lot Code: 0003 PCB Lot Code: 0000 Firmware Version: 102a Hardware Revision: 0400 Cell Revision: 0303 Charge Information: Charge remaining (mAh): 2194 Fully charged: Yes Charging: No Full charge capacity (mAh): 2289 Health Information: Cycle count: 120 Condition: Check battery Battery Installed: Yes Amperage (mA): 0 Voltage (mV): 12341 The page I read on Apples site said something about if the battery life is low if the cycle count is less than 300, then it's eligible for replacement. Being my first laptop, I had no idea that these batteries should be cycled. During the past two years of school, I'd take the power adapter with me so that's why there hasn't been many cycles. While I still plan to go to the Apple store, I'm just wondering if that is something they might hold against me. "You should've cycled properly" ... "This is regular for the age of this battery" (and who knows, it might be) I just want to get the facts straight before I go in looking like an idiot. Thanks.
