I bought a 2008 MacBook 3 days ago. In the info panel the battery is Charge Remaining (mAh): 2091 Fully Charged: No Charging: No Full Charge Capacity (mAh): 4047 Health Information: Cycle Count: 331 Condition: Normal Battery Installed: Yes Amperage (mA): -1410 Voltage (mV): 11512 If i close the MacBook and does not shut it done completely the bat. discharges as i would work on it. My guess is the MacBook fails to go to sleep for what ever reason or is it a bat problem. The screen does not go to sleep when closed either??? Pls help as i still can return the maschine within the next 3 days!
