My laptop battery has begun expiring with no “low battery” warning, somewhere between 30-40% power. This means my laptop shuts down completely no matter what I’m doing, with no warning at all, and I lose work if I’m not paying very close attention. When I charge the battery back up, it never just stays at 100%, instead exhibiting the utterly annoying behavior of bouncing back and forth between 99% and 100% capacity. Very visually distracting.
Now I have to decide if I can live with it until summer, when hopefully new MacBook Pros come out. I guess whoever I sell this laptop to would appreciate a shiny new battery, so I may as well buy one.
I’ll try recalibrating it, but I’m not optimistic.
