MacBook Pro battery not charging, even after resetting SMC many times

So there was a power outage at home due to maintenance that I was not aware of and for the first time in my life, I went to sleep, the night before the outage, without plugging in my MacBook.

I woke up to no electricity for about 5 hours and during the time I tried turning it on as usual. I had no clue what the battery percentage was at night before I slept but I was expecting some kind of response but didn’t even see a battery dead indicator show up. Still, without power, I Google’ed on my phone about what to do if this happens.

And quite stupid of me that I followed the first result, without any research, and reset my SMC (I had no clue what SMC was until I had already done it) which didn’t help at the time.

Fast forward to when the electricity was restored, I plugged in my laptop for around 2 hours and came back to 0%, which was creepy. I clicked on the battery icon and it showed a “Replace Battery” icon and that every app that was used recently “Using Significant Energy”, even Spotlight and System Preferences (I used the former to search the latter).

Also, the laptop is lagging a lot, how these Macs usually do when they’re less than 5% and not connected to power. I still have firm belief that it’s nothing to do with a circuit or logic board because I was using the laptop just last night and it was working perfectly.

This is what coconutBattery is showing up for me.

Lets review the MagSafe charger, first what is the color of the MagSafe connector Amber or Green?

Review this Apple T/N as well: Apple Portables: Troubleshooting MagSafe adapters. Make sure you have the correct one and yours is in good shape cord and connector.

Your battery is getting close to the end of its lifespan (707 cycles - max is 1000). While thats not the issue here do keep that in mind.

It looks like your charger is not charging your battery if you look at your CoconutBattery snapshot the current charge is zero! Once we know the color and brightness of the MagSafe charger LED and if its in good shape per the T/N we can dig deeper.

Power disruptions can create surges and power sags both can harm your power adapter and your computer. I would recommend getting a good surge suppressor or better yet a UPS. Lightning and felled (shorted) power lines can also be a cause.

Update (10/22/2018)

At this point you’ll need to try another battery.

Sadly, swapping batteries around is not a possibility with your friend system which would have been one way to check things as the batteries are glued into the uppercase.

From the sounds of it you are located in a very remote area on this big blue marble. Is it possible to get to someone what has access to the needed test gear and tools to test as well as replace your battery?

It is Amber when connected and after resetting the SMC, it turns green for a while and then amber again when the laptop boots up. I am hoping nothing happened to the charger although it was plugged in when the power went out. But they cut the power at least once a month so the charger has probably been through it before.

Need to add that the MacBook dies instantly after the charger is taken off but remains on as long as the charger is connected.

Thats not good ;-{ The constant power disruptions can kill the charger. You'll need to find a second power adapter and if you know the time point the power is lost, you'll need to unplug it.

For sure you need a surge suppressor! And in fact I would go with a UPS!

Yeah man, finding another MacBook charger won’t be easy but I’ll try it! It’ll take a few days so I’ll update this then. Thank you!

Update: my charger seems to be working fine my friends’ laptop and his charger isn’t doing anything to mine. It’s still stuck at 0% and shuts down as soon as the charger is disconnected. But, how can my battery die overnight?

It's quote possible the battery is gone! The way you've been using your system with the questionable power day to day suggests your system is run to the point of full battery depletion. This is what a cycle count reflects. It you had checked your systems cycles. While in your case you've not pushed it beyond the max, the amount of cycles in a short window of time can also happen. Here's a good reference: Determine battery cycle count for Mac notebooks. Check your friends system to get an idea on how his system is doing.

Im having a similar problem. I have replaced my MacBook Pro battery, charging port and charger cable. But my cable doesn't show a green or amber light and it does not charge. What else may I need to change?

@vaiapapagi73788 - Sadly the charging logic within the logic board needs attention.

из

@danj is the logic board the same as the mother board? I’m new to all this do I know the basics. Can you possibly post a link of what I need to buy to replace? Thank you.

из

@iqgtewuysp9fs7v - Replacing the logic board (mother board) would be quite expensive! When the cheaper option is just getting it fixed.

There are shops which have the skills and the needed tools to fix this. That’s what I would do.

Where do you live? Maybe we can aim you to someone. Give us your country and nearest major city.
