Laptop dies when unplugged
I replaced the battery in this MBP just over a year ago. It now shuts off immediately when unplugged and Coconut Battery registers no battery at all.
Does this indicate a faulty battery or a logic board problem? The latter seems more likely to me, but I’m asking because a battery for another computer of the same model that I ordered from iFixit around the same time last year also recently turned out to be faulty.
