I've got a pretty old macbook pro, I would assume it's intel. I'd installed refind and debian on it then just left it for a while. No damage that I know of, but I did move houses. Now, I plug it in and the power cord shows green, and the battery indicator shows blinking fully bars. I have tried all the keyboard things to reset, but no luck. Is this thing fucked, or are there any possible solutions? Thanks for the help guys!
This happened to me on a fourth generation Intel MacBook Air with Refind and Fedora. When you say all the keyboard things, do you mean resetting the NVRAM and SMC?
I thought I did the NVRAM, but it turns out I didn't hold down the buttons for nearly long enough. After what felt like two minutes, I got the "Bong" sound, and I was back in business.
I held it for about 5 minutes, and still nothing. I do have a french keyboard, so I don't knopw if that might impact the key combo? I think it wouldn't however, just cause it still has option(written as alt), cmd, and p+r. No other guesses, the laptop is completely unresponsive. Thanks for the idea, I will probably just take it apart and look
