I suspect this is because my machine has a dead firmware battery, which it may have always had- I've always noticed that exhausting the main battery would...

    2011 MacBook Pro won't stay on

    Hey everyone, so a little backstory on the laptop before I explain the problem. A couple of months ago, I took it to Micro Center to get it fixed. They concluded that the logic board had to be replaced and maybe the top case. The repair was almost $1,000 so I just bought a new laptop. It has...
