The battery om my 15" MBP (10.7.5) which is in daily use has suddenly died with no warning. Yet earlier this week it happily ran a server in a VM for over 4 hours on battery. Battery Status reports Condition: Replace Now Profiler reports Code: Charge Information: Charge Remaining (mAh): 6336 Fully Charged: Yes Charging: No Full Charge Capacity (mAh): 6336 Health Information: Cycle Count: 144 Condition: Replace Now Battery Installed: Yes Amperage (mA): 0 Voltage (mV): 8441 The Magsafe adaptor light is green. IStat Pro reports a battery health of 92% and agrees with Profiler's cycle count and charge status. If I disconnect the power supply I get an immediate power down. I have tried an SMC reset but it made no difference. Anyone had similar experience and able to advise whether my battery really has just died or whether its a glitch that can be fixed without a battery replacement?
