Hey all, I just got a new to me macbook. The previous owner said that it would not hold a charge because it needed a new battery. Today I installed a new battery, but the symptoms are all still the same.
The unit will work just fine when the power supply is hooked up. If you disconnect the power supply, the unit will instantly turn off. I looked up the "power" settings under system profiler and this is what it showed:
Battery Information:
Model Information:
Serial Number: XXXX-YYYY-0-0
Charge Information:
Charge remaining (mAh): 0
Fully charged: No
Charging: No
Full charge capacity (mAh): 0
Health Information:
Cycle count: 0
Battery Installed: No
Amperage (mA): 0
Voltage (mV): 0
AC Charger Information:
Connected: Yes
Charging: No
So based on that info, I'm thinking there must be some kind of internal problem with the mac. Opinions?
