confirmed this model is to use 60W charger move MagSafe charger port back out to just-behind case Just last week it seemed like the charger top was having problems connecting, got it to work for a few minutes, and then suddenly it stopped working at all (nothing on screen, no fans, no lights of any color on charger tip of computer). I am having a similar problem with my 13” 2009 MacBook (white, unibody, A1342). Once on, the computer appears to work absolutely perfect. attempted to do an SMC reset (although I don't see any sign of rather it happened or not)ĭoes anyone know why the power button would turn the computer off, but won't turn the computer on? This is even though removing the mag safe, removing the battery, and then reconnecting the mag safe power supply does turn the computer on automatically.
ran Apple Hardware Test in short and extended mode without any issues identified,.repaired Disk and Permissions in Disk Utility,.tried jump starting the computer on with the jumpers but this did not work,.replaced the keyboard twice (the second and third keyboards work correctly),.replaced/soldered a new keyboard connector on the logic board as it had a missing pin,.
#Backup power supply for macbook pro pro
Yosemite OS X 10.10 on mid 2010 MacBook Pro 15" The power button turns the computer off, but not back on. When the battery is plugged in, the 'charging' LEDs on it do not light up or blink and thus the battery does not charge. Lastly, when the MagSafe adapter is plugged into the machine, the LED on it always glows green-whether or not the battery is plugged in. One thing I haven't tried yet is to open it up and check the top cover power switch is the power switch something that frequently breaks? The other thing I've read could be at fault is the ' Left I/O' board', but this thing won't turn on when using AC or a battery. I've read about the nVIDIA 8600GT issue, but I don't get any response from the machine at all, so I'm not sure if that's what the problem is. I can't get it to turn on whether it's plugged into the AC adapter or on a battery, I get no visible or audible response from the machine when I push the power button-none of the lights turn on, none of the fans spin, etc.
