I've been trying to charge my macbook all day, but it will not charge - the adapter light (green or amber) will not even turn on, and the computer is cold. Is it likely the adapter, battery, or something larger?
MacBook Pro, OS X Yosemite (10.10.1)
Hi jsfisher13. If you have access to another mag safe power cord you could see if that is your problem. Otherwise you could try a SMC reset.http://support.apple.com/en-us/HT201295 Hear is for checking the mag safe power adapter.http://support.apple.com/en-us/TS1713 . Does it turn on with adapter plugged in. Sometimes the green light is so dim it's hard to see. Or your battery is bad. If you have the Macbook turned on you can hold the option key down while clicking on the battery icon. If battery is good it should say normal.
I tried another mag safe power cord and the results didn't change. I also tried the SMC reset. Nothing. I've also removed the battery and tried to start it with just the power cord. Nothing.
Hi jsfisher13. Will your Macbook Pro start up with battery and power cord attached? If so, download coconut battery app. I will give you a link. I have a 2009 Macbook that my daughter uses and it does not show as charging and will not run with battery removed. What I found is, that with coconut battery app, the Macbook was charging . But it was so slow that it would not show in the apple systems power or at the battery icon on the top menu. The charge rate was between 2.5 and .3 amps.Should be at least 12 volts. or 23 amps. Her Macbook took 8 hr. to go from 30% to full charge. If you can not see any green at all on the mag safe power adapter, even a very faint green you might have a defective dc in board. That is what you are plugging the mag safe into. It plugs into the logic board. You would have to take it to the apple store to have them run a test on it.http://www.coconut-flavour.com/coconutbattery/
My MacBook Pro will not charge (no light on adapter)
