A Quick Fix for “No Batteries Available” & Fans Running Constantly on a MacBook Air

May 7, 2013 - 252 Comments

MacBook Air

If you’ve ever had a MacBook Air or MacBook Pro’s battery disappear at random it can be a disconcerting feeling. This is often accompanied with the battery menu having an “X” through it and saying “No Batteries Available”, a very sluggish Mac, and even after a reboot or not the Mac will often have fans running at full speed despite nothing unusual showing up in Activity Monitor. To top it off, the MagSafe charger light typically is not lighting up, and the computer won’t even sleep. Uh oh, something is terribly wrong, right? Well, sort of – but don’t worry, this is all related and it’s a peace of cake to fix.

Before getting into any specifics or the details, let’s cover the solution: an SMC reset.

Get the Battery Back & Fans Normal By Resetting the SMC

This is a technical process but it’s very easy to follow. This will be the same on a MacBook Air & MacBook Pro Retina, technically any Mac with a built-in non-removable battery. You can find instructions for other Macs and older Macs here if needed.

  • Shut down the MacBook and connect the MagSafe power adapter – let the Mac completely power down before proceeding any further
  • Hold Shift+Control+Option+Power concurrently for a few seconds, then release
  • Press the Power button as usual to start the MacBook

Here are the precise key sequences for what an SMC reset looks like on a MacBook Air or a MacBook Pro (Retina) keyboard:

Key sequences to reset the SMC controller on a MacBook Air and MacBook Pro Retina

After the Mac has rebooted normally again, things should be all well and good again. Here’s an example of the “No Batteries Available” menu, then after the fix the battery is shown functioning as normal again:

No batteries available, shown on a MacBook Air

Note the total elapsed time in the clock is 2 minutes. In other words, it took only two minutes fix the entire problem, from adding up all the power-related issues, saving an important file or two, shut down the Mac, reset the SMC with the aforementioned keyboard sequence, then reboot the Mac to normalcy again.

Power Preferences will reset too

It’s important to point out that resetting the SMC will cause you to lose many power-specific options and customizations you may have made to OS X with System Preferences, ranging from screen brightness levels, to settings in Energy Saver for how the Mac handles things like auto-dimming based on lighting and power sources, screen sleep behavior, sleep when idle, etc. Thus you will have to go back and make those minor power customizations again.

Why does this happen?

You won’t always find an exact reason as to why the system management controller goes haywire along with core system and power functions, but the basic idea is that at some point something was corrupted, maybe for a reason or maybe not.

What is an SMC anyway?

For those who don’t know, SMC stands for System Management Controller, and it handles power functions and other core hardware roles on Macs, thus inexplicable issues with power management are almost always resolved by resetting the SMC. This is why for problems or oddities with power management like batteries disappearing, refusal to sleep, a very sluggish Mac combined with system fans blazing loudly, graphics cards acting up, are all very classic symptoms of needing to reset the SMC to get things back on track. Take the time to do it, it works.

Having run into this twice on two different Macs in the past week it’s certainly a worthwhile topic to cover, even if it’s a relatively rare problem to deal with. At the very least, it helps to be informed of these kind of things, so if any of the above happens to you, before calling AppleCare or taking a trip to the Genius Bar, take a moment to reset the SMC yourself, it will almost certainly fix the issue completely.

    Incredible article. thanks very much

  13. Roger Lapin says:

    I always find that a hoover into the fan on a MacBook and suck out all the dust will stop the fan spinning as the main reason is lack of airflow.

  19. Mac Mike says:

    If your system info shows no battery it is likely your battery or battery motherboard connection maybe loose. You will need to open the Mac and check the cable.

  25. Srikanth Nallagoni says:

    Fantastic worked me like magic :-), may i know how it resolved the issue FAN and power status

    • vineeta says:

      Like the circuit breakers in your house, these fuses are designed to break the electrical connection when too much electricity causes your fan to overheat. When the fuse melts, it breaks the connection and cuts power to the fan. Check the cord and the inside of your fan for this fuse

  26. AC says:

    I tried this and now my laptop wonโ€™t turn back on. Like at all. Any advice? Iโ€™m freaking out a little?

    • Trhn says:

      Plug in your laptop to a charger, reset the SMC, then turn it back on. Sometimes you have to let the Mac stay plugged in for a few minutes before turning it back on again.

      That also might mean your battery is no longer functional if it does not turn on when the power is not plugged into the Mac laptop.

      Make sure the power outlet works of course.

      • Joshua says:

        Hello, different person here but I have to say,

        It still didn’t worked for me (the whole process). Even though my charger is still lit (red) but it’s not charging up. And before all of this happened, my MacBook air suddenly died while the battery is still 64 percent (I’m not charging btw). It’s completely unexpected. The only way for my MacBook to still work is to let my charger connect to my laptop, until I’m done using it and proceed to shut down (and unplug the charger of course).

        You think my Mac still has a chance to fix without going to an expensive trip to the Apple Store? if ever? any other options? I might go to cheaper independent Mac repair shops but still…

  27. Olga says:

    Thank you very very much!
    It solved the issue!

  28. Yeet says:

  30. vira says:

    Tried on my daughter’ macbook air, but does not work. any other suggestion. as soon as I unplug the magpull charger the macbook dies…

    • Paul says:

      This works if it is a software or simple firmware SMC/VRAM issue, but if this does not work to resolve your ‘no batteries available’ message on a MacBook Pro or MacBook Air then that means the battery has failed and needs to be replaced.

  31. Stephen says:

    I canโ€™t believe it was that easy. I just went through an hour of panick and then I found this article and 2 min later, I GOT MY MAC BACK!!!! You guys are AMAZING!!! Thanks a bunch

  34. Lumi says:

    Thank you sooooo much

  35. Stephen says:

    I was stressed out for a few minutes, as when I powered on my computer, I noticed the “No Battery Detected” sign, that the MagSafe charger light was not on, and that the fan was loudly blowing. However, I then found this INCREDIBLY HELPFUL PAGE. Such an easy fix and so well explained.

    Thank you!


  36. Jen says:

    Wow, super helpful information. My cat chewed my power cord and caused a weird short that shut my Mac off. When I turned it back on, the fan was going crazy and there was a no battery sign. I thought that both my cord and Mac were dead…almost panicked and then I found this post. Thank you!!

  41. Jill says:

    This repair seems to have worked now, but after 2 attempts of holding Shift+Control+Option+Power buttons. The first time, my MacBook Pro (early 2015) restarted with the same problem- loud, continuously running fan, no battery icon in menu bar and no charge via power cord. I did the same thing a 2nd time and it seems “magically” fixed. Fan is totally quiet, power cord charging and battery icon reappeared in menu bar. Thank you so much!!! I thought my Mac was going to explode and die.

  42. David says:

    You are really good it worked like magic .Thnk you so much i appreciate you.

    Thank you sooooo much… I was really panicking when the laptop just shut off after doing some silly stuff… I was already wondering how much this will cost me until I found this very helpful troubleshooting steps you’ve provided. Awesome! Thanks alot!

  45. Tom says:

    I unplugged the battery cable in the middle of the computer and plugged in again. Just remove (unscrew) the back cover, unscrew and disconnect the battery plug. It works for me.

  46. T says:

    THANK YOU SO MUCH! I was panicking, even thought i might need to get a new laptop. this worked for me. again, thank you!!

    Thank you for this info – worked for me!

  49. Danny says:

    Thank you, thank you, thank you!

    Dodgy (worn out) charger cable shorted my computer, and when it restarted, it said “no battery available” (but still, somehow, was running on battery power). I also couldn’t get the (good) charger to connect. After holding down those keys, the charger light lit up and I have battery again!

  57. Katrina says:

    What if SMC reset won’t work?

    The problem with my macbook pro retina (early 2013) is it stopped turning on the normal way. it won’t turn on with power cord already connected then pressing power. it will only turn on by pressing power button followed by connecting power cord with noisy fan all throughout. Battery info not showing from “system report” or even when doing Diagnostics.
    Tried to reset SMC many times, nothing happened. I tried to disconnect/reconnect battery cord from board, still did not fix the issue.

    Is it that battery needs replacement already ? Will it cost me to have an Apple Store tech confirm the issue?

    Thank you soo much… Appreciate any comments from you!

    • Sarath says:

      I am also stuck with the same issue. No charging happening and the light on the magsafe charger is absent. Keep the power button pressed and connect the magsafe charger..hold for 10 secs, remove the charger and leave the power button, repeat the same procedure for another ten seconds. The mac powers on the main supply. All functions normal except for the fan running a high speed continuously. I have also tried disconnecting the battery by removing the rear panel. In case you come across a solution, please do post. I shall also do the same..Thx

    • Danny says:


      were you able to solve the issue?

    THANK YOU ๐Ÿ˜

  63. Jen says:

    This started happening when my computer was at 1% battery, so it ran out of battery and it won’t charge because of the no battery thing. How do I fix this?

  64. Kate says:

    THANK YOU!!!!

  65. Mel says:

    Thank you! Didn’t have to spend $$$ on an easy fix.. Thank You! Thank You!

  66. Eric says:

    The best I think would be just to keep your Macbook Pro charged as and when it is possible to not wear down the battery in the first place. It is a myth that plugging in the charger all the time will diminish your Mac’s battery life. When the power is full, the Mac draws power from the Magsafe charger. In any case, you can always go for battery replacements at independent Mac repair centres which are a lot cheaper than Apple stores.

    I have tried the SMC resets and it almost never works. Once the service battery prompt appears, the battery life diminishes very fast.

  89. Mat says:

    The problem with me happened after a malfunction on magsafe. A little trouble with my power source. After the forced shutdown, maybe the mac protection against mal function, the new boot began with theses troubles (fan always on, missing battery).
    I made the procedures and with a new power source (the old didnt work more) all turn back to normal. I had fear of burning magsafe board, but nothing happen. Just reset things and mac is working fine.

I normally don’t leave stupid reviews.. but this made me so happy! Thanks for the help! P.S. If anybody is wondering, you don’t need to buy a weird adapter thing, it worked for me by just shutting down and holding shift control option ad power for like 20 seconds. Thanks!

  99. Hector Ruiz says:

    Hello! This is the first time in 5.2 years with the Mac Air. Incredibly simple and easy. Thank you so much.

    Strange but today I got some files from an infected USB (from a Winbugs computer), I was not able to read the files, I say 2 files instead of 3, then the person used a single.ZIP file, then the ZIP, once unzipped showed another .ZIP file, not the 3 original files, we had to format the thumb drive.

    So at this point in time I don’t know if the problem was because of the virus or because of the age of my Air, having lots of PDF opened files (about 30)

      Macs can not get Windows viruses. Mac is entirely immune to any and every Windows virus, so the data on the USB drive from Windows would have no impact on the Mac.

    What I did was pram reset SMC reset al logo read many webpage and al the suggestions goes to the SMC reset.

    First I did get the MBP and it was doing nothing, light was not burning (MacSafe adapter)
    Tried several boot methodes but what did work was a tip i read from this support forum.
    remove battery remove MacSafe, hold down power button 10 sec, the reconnect MacSafe adapter, stil holding power button down and now for another 10 sec, release it and then startup the normal way.
    The MacBook Pro booted “normal” but with loud noise from the fan (maximum) I started again in safe mode and repair permissions, booted again and still Loud noise.
    Started activity monitor and the was no much CPU use from any program,
    Put back the battery and did a boot. No go Then MacSafe attach and the MBP started but in it did say no battery
    All the time the light on the MacSafe adapter was OFF.
    It only gets green when the MBP is 100% off and the MacSafe adapter is attached then it is green

    Tried several times SMC reset bit no go. (According to several website this would solve the problem) (even followed Apple webpage about is (removable battery)
    The MacBook Pro is normal working but with loud fans and only with the MacSafe adapter attached.
    The battery is replaced 2 years ago. It would not charge and was bolded, now it is in good shape from the out side.
    When I push the button on the the battery the lights ar not lighting up.
    Again with the battery removed I have the same problem (very loud fans, maximum , and no light on the MacSafe adapter)

    O one last thing it would also not get into sleep mode thats why al the things lead to SMC reset, but no go

    Question if I buy a new battery, could that solve the problem? I don’t have one nearby, so I will have to buy it.

    Thanks for any suggestion

    Thank you so much! I’ve had my Mac for over 4 years now and I was sure it was done for. I’m so happy I Don’t have to get a new one :D

  149. Marie says:

    Travelling for work far away from the mac stores and this just happened to me, I was ready to really panic, but your solution worked, amazing, thanks so much!!

  150. Katie says:

    Just tried this and still nothing. The battery displays and X and the fan is going. The computer works when it is plugged in, but very very sluggish. The light on the charger stays green, not turning to orange like when it is charging. I have a MacBook Pro from 2011. Any other suggestions?

    a word of warning!! the advice above is sound…. for a while!! iv had this problem for five months now and the above advice helped but I found i had to reset every few days. Now the machine completely ignores the key commands and goes into safe mode. my problem is the keyboard keys only work in upper case and keys for most programmes are garbled.

    • uhbtn says:

      it sounds like your Mac is overheating and maybe is getting damaged, it has nothing to do with the advice. You should take it for repair.

    Sometimes problems arise and theres no solution in sight or should that be on sites, or, the solutions given are impossible to follow, or don’t work.

    This wasn’t one of those times. Your solution worked like a miracle, it truly was amazing.

    Thanks for giving me back my mac ;)

    I am sorry but this doesn’t work does your laptop have to be up-to-date for this to work

  173. Sophie says:

    Amazing – thank you so much – and thank you for illustrating with the picture! I had read the SMC reset instructions elsewhere but obviously kept getting it wrong because I was pressing the ‘cmd’ button under the mistake impression that was the ‘option’ button! Was thinking my macbook must be immune to the SMC reset! Saved me a boring and inconvenient trip to the Apple store and a lot of stress and anxiety!

  174. Solom says:

    Thank you so much. Simply followed your three steps in my MacBoo Pro with Win-7 and it solved my problem.

  181. Mike@vossen says:

    My mom just bought a new MBP in Atlanta and it started acting up. She came here to help out with our new child and just said it was broken lets go to Apple. We went to Apple and of course its like a week wait to do anything (I totally forgot to schedule an appointment).

    So I decide to take some time to figure this out and the problem was exactly as described in this article. The fix provided worked like a charm. I cannot say enough thanks, my mom is super happy!!!!

  194. C. Freire says:

    OMG!!!! THANK YOU!!! I like to think of myself as a tech-savvy mac junkie, but when my MBP Retina started to go haywire for no reason, stopped recognizing the battery, and even the power connector wouldn’t light up, I was as helpless as my great-grandma would’ve been if asked to troubleshoot an iPad! This was a life saver, so simple, yet so effective! The article’s being saved to my Evernote, and I’ll have to do some soul-searching: maybe accept I’m not as “tech-savvy” as I used to believe… :-) THANKS AGAIN!!!

  205. Brandon says:

    My Macbook doesn’t switch on anymore after following these steps. Any solutions?

    • Tom says:

      I unplugged the battery cable in the middle of the computer and plugged in again. Just remove (unscrew) the back cover, unscrew and disconnect the battery plug. It works for me.

  211. Nicky van Zanen says:

  216. Alan Hudson says:

    Good fix. Worked perfectly. Thanks

  217. Jeremy says:

    A huge thanks for this fix. It worked. Saturday night when my MacBook Pro just died and after turning it back on, non-stop fan, non-stop panic and “no batteries available.”

    Now everything is working again… :)

  218. Alex says:

    Thank you SO MUCH for this fix information.

  219. JC says:

    Hi, I have a mid 2010 13inch Macbook Pro. My fan is on full blast all the time. The Macbook doesn’t appear to be warm, let alone hot. I also have no battery. tried changing it but still.. no battery.

    Tried the SMC but no luck unfortunately. I’m thinking a sledge hammer might do the trick?

  220. Emily says:

    Thank you so much for writing this!!

  221. Chuck says:

    I’ve tried this fix several times and its still not working. I have a MBP which was purchased August 2012

    • George says:

      Same here โ€“ nothing happens, I also tried it in different ways and constellations, and no change in settings or anything. This one is MBP mid 2010. Is there some other way to achieve this?

  222. A Rivera says:

    Thank you, thank you, thank you!

  223. Greg says:

    Great article! Easy to follow and worked perfectly.

  226. shell says:
