Sudden "No Battery Available" error, multiple SMC resets to no avail

Hi folks,

I was recently greeted by the dead battery icon (black "X” inside the battery icon in the menu bar, and it says "No battery available“ when I click it). This came out of the blue, without any warning (I've had the "Please service the battery“ on previous Macs I owned).

I've tried to reset the SMC twice (for my 2015 MBA: turn it off, hold shift + ctrl + option + power for 10 seconds, release, see the charger led blink and turn back on) with no effect.

Even if the UI says so, the battery isn't actually fully dead: when I unplug the charger, the computer hibernates.

Any advice? Is there any way to probe the integrity of the SMC?

Kind regards,

—Pierre-Yves

Edit:

Here's the CoconutBattery screenshot with the power cord plugged in:

I can't take one on battery, the computer immediately goes to sleep.

Hi, thanks for the suggestion. I won't be able to take a screenshot with the MagSafe disconnected, the computer immediately goes to sleep mode.

Would the "plugged" screen cap still be useful?

Yes, the plugged in one is still useful. Sometimes you can get enough charge to snap with the battery only condition which gives us an idea on the drain in case its high. Post what you can.

There you go! I'll try to take one as fast as possible after unplugging, but I'm not too hopeful, it may still hold enough charge for the computer to hibernate, but it doesn't respond to the OS when probed...

by

Well, "cmd + shift + 3" doesn't work after unplugging. The screen goes dark immediately. Hitting the key combo turns it back on for an instant, but no screenshot is taken.

Surprisingly, the caps lock LED remains reactive deep into the slumber.

@danj I suppose there's no hope given the CoconutBattery output...

Lets get a better view of things. Install this gem of an app CoconutBattery and then paste a snapshot of the main window of the app here for us to see Adding images to an existing question If you can, do one with the MagSafe adapter plugged in and the second with it disconnected.

Thanks Dan. Could the behvior I describe be due to a faulty connection?

The Mac is still under warranty, and sending it for repair means at least 48 hours of downtime if they have to order the replacement part...

I would go to an Apple Store or ship it to Apple repair depot. When you call in to support they will ship you a box to send your system. The shipping will be covered under warranty.

Thanks for the info!
