Hi! First of the "batt," here's the info: Battery Information: Model Information: Serial Number: Sony-ASMB012-372d-9c4a Manufacturer: Sony Device name: ASMB012 Pack Lot Code: 0003 PCB Lot Code: 0000 Firmware Version: 102a Hardware Revision: 0500 Cell Revision: 0303 Charge Information: Charge remaining (mAh): 3053 Fully charged: No Charging: No Full charge capacity (mAh): 3334 Health Information: Cycle count: 208 Condition: Check battery Battery Installed: Yes Amperage (mA): -1746 Voltage (mV): 11904 I've had my MBP since October and I am pretty shocked at the decrease in battery life. I never leave it plugged in except to charge. I need to have it have at least 3 hours of battery life for my classes. *Sigh* I'm going to take it to the Apple specialists at my Uni. Do you think they'll replace it? Should I leave it plugged in more often? I try to calibrate it once a month, should I do it more often? Thanks!
