Battery going out, no adapter works.

I'm losing power. On a MBP with Yosemite.
Coconutbattery app says the battery is okay, 562 loadcycles.
Three power adapters tried, none work.
Have done the SMC power reset. No change.
Tried to get Disk Warrior to load via flash drive, but it won't.

No symptoms of anything. It was charging fine one moment and not charging at all the next.

If anybody has any idea short of taking it for service (I can do that tomorrow), please advise. I'll monitor via phone in order to save some battery for any suggested actions this forum may have.

Thanks.

Do any of the lights show up on the charger connector? Or is it behaving as if the charger isn't plugged into the AC outlet.

Are you sure the AC outlet is OK? If you're using an AC cord instead of the "Duckbill" direct to socket plug, do the different chargers have different AC cords?

Just wondering if this is really an AC power problem rather than anything with the computer, and if the outlet or AC cord might be bad.

Other possibility to check is contact between the magsafe plug and the computer, is it a snug fit, or does it wobble a bit which might be due do some debris in the computer side of the connector.

Hi,

No lights. Connection is solid and port is clean.

Tried two other outlets. Direct to wall. Other things got powered. Not the Mac.

Got Disk Warrior to run. Didn't help.

Maybe it is the magsafe board. Drat.

magsafe boards themselves aren't a high-cost part.

labor may add a bit.

Have you looked carefully at the port ON the computer? Anything in there preventing full contact?

Does that power brick work on another Mac?

Have you checked the power brick with a VOM?

The port looks okay. I don't have another one to check with. My wife's MBP is already in for repair. First time ever both have gone down at the same time.
