Battery not charging, unexpected booting

Starting a new thread. New battery is in the MacBook Air. Put it in yesterday. In 12 hours has not charged the new battery. When I went to do a SMC reset and did shutdown, it rebooted on me twice without encouragement. Then I did power it down. Do the reset and it wouldn't boot. Disconnected the power cord and it booted.

Something is clearly wrong. How hard will it be to fix? I think this is something about a logic board?

Thanks

Annamarie

The spontaneous reboot is not something I knew about. The battery is good. There's something else wrong.

(This is a new one I put in two days ago.) Here is the Coconut Battery

So now it won't boot at all. Yesterday after I did the reset SMC it charged up nicely. I then did the battery calibration. It won't boot this morning. Sigh. What next?

Update (04/24/2018)

Opened the case - did the disconnect battery thing. Closed case (I'm getting good at those tiny screws) . Tried to boot from battery. Nothing. Attached power cord - it booted without my holding down the power button. Booting wihtout holding down the button has been happening from the beginning of my trouble shooting. Coconut battery has the battery all green with 100% charge now.

And in case this is relevant - I often have to jiggle the power connection to get the light on (in other words connected.)

Might have written too soon. Does seem now to be charging the battery. Gone up 10% in last 20 minutes. But I don't like the uncontrolled booting that happened.

What does CoconutBattery show you?

You are causing a spontaneous reboot by disconnecting the battery and mag-safe then reattaching them. This is perfectly normal. Also, if a battery is to weak to boot a machine and the power on button has been pressed, it will boot up on its own as soon as the battery is charged up enough. Download and run Coconut Battery as Dan suggested so we have a better idea of what happening.

UPDATE

That battery is fully charged. Disconnect the mag-safe let it run down. Test it with Coconut to see where it's at. Pull in the mag-safe, then see if Coconut shows it to be charging. If it ain't broke don't fix it.

Annemaria - At this point its clear your battery issues have been resolved.

Sadly, you still have something a miss here thats causing your system to fail to boot up. I'm suspecting your keyboard had something spilled into it.

I would recommend you let the Apple Store take a look to see what they say.

Apple wont' touch it - it is a "legacy" machine - older than 5 years. I took it there when I was in Portland (where my niece lives whose machine it is.) I do have a local shop - they demand a $150 deposit just to look at it. My niece is struggling and can't afford a new machine. A workaround? Since it will boot when the battery has been disconnected and then reconnected, ship it to her with a P5 screwdriver and have her boot it once and then never shut it down?

Sorry, I can't offer you more here. Logic board repairs can be tricky! It could be as simple as a cold solder joint or as complex as needing an other major chip or two.

The other option is just replacing the logic board which is quite easy in this model. The only rub here is a new board can be between $250 to 325 depending on the CPU's speed.

Well thanks for the help up to now. and the perspective on the issue. I think that I'm going to tell her to use the workaround. She won't be able to travel with the computer - but she can leave it on. It will do a restart, just won't boot from a shut down. Better than no computer at all?
