Chosen Solution
Strange, and a little like halloween. Here is how the story goes: Went out of town, important things to do on MacBook pro. 15” . Turned it on, one chime… that wasn’t quite the same as usual, and a DARK screen… nothing! Called the refurbished guys I purchased from and they lead me through different combos of holding multiple keys down, twisting (lightly) on the screen. Shining a light through the apple… Nothing worked. I tried it intermittently over the next monthISH. Nothing. I was set up to send it back in… then it started working again. This happened 2 times at that location about 6 months apart. I just figured my MacBook didn’t like the location (I KNOW!!! stop laughing) Time went by, all was well… then the other day I was scanning a bunch of stuff, and I heard the chime…. then looked and the screen was black. Same thing again only in the middle of working, (the other times were from start up) Tried restarting NOPE. x 3 NOPE. THEN: I unplugged printer from usb, unplugged external ssd IT WORKED. Still scary to be without my MacBook long enough to send it in. Is there a (reliable… not seat of the pants as I describe above) way to come out of this dark scary place the next time this happens. (my version of the cute little tv series EUREKA… is too stressful) UPDATE: Per Dan’s suggestion - Battery Health 2 app was on the app store so I used it. Looks like coconut battery was replaced by something that got bad reviews so I went for the likable one.
@nan_c - Why did you switch to Battery Health 2 I wanted you to stick with the better CoconutBattery as it a better app. If your system is on the recall list I would make the effort to get the battery replaced ASAP as you don’t want a surprise!
