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!
How old? Is the battery removable? If so, you can try removing the battery, holding down power for about 10s, put the battery back or plugging in the power cord, then retry booting it
