Ideas? Power button doesn't turn on computer.
2011 MacBook Air belongs to my niece. She says "it just stopped working one day." No signs of life from the power button. I researched. Found a fix on line about removing the battery cable for 30 seconds plugging it back in. Brought computer home to where I have tools (Portland OR to Vermont!)
Opened case - removed cable. Put it back. Tried to boot. Nada.
Attached power source and voila it booted! Shut down once and restarted.
Shut down one more time and we are back to it not booting.
Would love suggestions about what it wrong. Clearly it is hardware. New battery? Power connection?
Thanks

Hi there,
Okay got it running with the battery connected and got these images. (2 are the same - but I can't figure it out. I ordered a replacement battery today along with one for MY computer which I learned is in need of replacement while doing this. (Exact same model and year.)
What's a little funky is the way the machine turns off and then boots. The MAGsafe is green. Has been for awhile. It wasn't connecting yesterday but I cleaned it and that might have made a difference? But right now it seems stable and is on with the battery connected. I did discover that the settings for the battery were set to NEVER turn off. Ugh.
Any other thoughts? This has been really helpful.

Hmm.. I wonder why they were so grainy - might have been better to share a dropbox link? Anyways I took a screenshot and used Airdrop.
It's got 826 loadcycles.! Menu applet says Service Battery with the triangle.
Computer has been stable and on for 12 hours - with the battery connected and power connected.
I've learned a lot.
Esta é uma boa pergunta?

Annamarie - Once you get the system responding again see if you can restart the system using the menu option 'Restart...' and then press and hold the D key to enter into the onboard diagnostics. Let us know what error code it offers up.

Can't run it if I can't start it?

Actually Dan - I was going to do that, that's why I turned it off. But now it won't start again.

Ough!! Let's try this: Pop the bottom off again pull the battery cable like before, now with it disconnected press and hold the power button for a good minute. Then only connect the Magsafe cord. Will it start then?

Yes, I have the back off the battery unconnected and it's booting. Now what? Run diagnostics without the battery?
