Is this a battery or logic board issue?
I've been having what I hope to be battery issues for several days. The problem started when I noticed that the battery wasn't charging even though the power cord was plugged in (I have several power cords, so the problem is not with the power supply). After finally getting the battery to begin charging again, if I remove the power cord, my MacBook Pro immediately shuts off and I am unable to get it to turn back on again (or begin recharging again) without resetting the SMC:

I have had to do this several times in the last day or two. Going to About This Mac > More Info > System Report > Power, here is the Charge Information:
Charge Remaining (mAh): 10038
Fully Charged: No
Charging: Yes
Fully Charge Capacity (mAh): 10523
Health Information
Cycle Count: 1055
Condition: Normal
Battery Installed: Yes
Amperage (mA): 1658
Voltage (mV): 8365
The laptop is less than 4 years old, but Apple Care ran out last year. Are there any other tests to determine whether the the battery needs to be replaced versus the issue begin more serious (i.e. logic board)?
