MacBook battery charger light flashing

The charger light on my Macbook flashes orange/green when fully charged. It goes to 100% then it turns green. A few seconds later the light turns to orange again. And it keeps going on like this ...
I tried shutting it down, updating, removing the battery. What should I do?

Have you tried resetting the PMU?

I can't turn on my MacBook Air despite trying to hold down the power button and using the SMC method. BTW my battery charger lights up to a green when plugged into the laptop.

Hello cass528,
I would be concerned too if my MacBook Air would not power on. I recommend following the steps in this article when experiencing an issue like this:

Macbook Pro shut down because the battery power ran out. Now I cannot start it and the battery will not charge. Only one green battery charge light lights up and blinks.

My Macbook Pro shut down because the battery power ran out. Now I cannot start it and the battery will not charge. Only one green battery charge light lights up and blinks on the left side. I am running Lion. How do I get this to charge and turn on? Thanks

If your model Macbook Pro is the calibrating model, let the battery calibrate.
If not, and are still under warrant or have Apple Care, give them a call and get a case number. Otherwise, take the computer to an Apple store or an AASP. Whichever is more convenient for you.

Macbook Pro charger light is orange.

Macbook Pro charger light is orange. I has always been green before. This time I got a "low battery" warning at about 20%. When I plugged in charger it went immediately to zero and the light is orange. Problem?

Note that if your machine has a built-in battery, it doesn't need to be calibrated.

My mac book pro is on, but the power light indicator is not on, the battery charging light is not on, and the computer is making a whirring sound, what is wrong

My mac book pro is working, but my power light is off, the battery power light is not on and my battery power symbol is a black x. My computer is making a whirring sound sort of like it does when loading a CD. I had a hard time getting the computer to turn on, used the command, option, P and R buttons to turn in on. I have tried restart, but I still get the whirring sound. What is wrong and what do I do?

Didn't do an SMC reset. But in attempting to find out about what that was I found some things to try first. Also, when I went to system preferences - hardware, I couldn't find anything regarding power and battery info. Finally, I unplugged the computer for several seconds, then shut it down, removed the battery, put the battery back in. Then I turned on the computer, plugged in the power cord. Problem solved- no whirring sound, battery charging light is on.
Thanks for getting me in the right direction.

MacBook Pro Will Not Turn On. Charger light flashing

Hi there all. I am having a problem with my late 2011 MacBook Pro, and I have tried everything. I was wondering if you might be able to help. I will describe the problem in detail:
This morning when I woke up and went to use my macbook, it said the battery was 50%, even though it was plugged in. I use it like a desktop, plugged in to a monitor and plugged in to power most of the time. I usually allow it to drain the battery every few days. Anyway, I rebooted it, and the battery was still going down. I tried various things, like unplugging it completely etc. I remembered that my friend had this problem last year, with her exact same model macbook, and she came to me, and I was able to fix it. So, I thought if I followed all those steps I would be fine. I reset the SMC and PRAM. At this point the battery was showing at 0% when the OS (mavericks) loaded, and then after a few minutes the computer switched itself off completely and with no warning. The light on the charger was sometimes showing orange but didn't appear to be charging after several hours. The battery indicator was flashing 3 times on the first light then fading. It was not turning on at all now.
So, I decided to do what I did to my friend's macbook to fix it. I unscrewed and removed the back cover, then i carefully unplugged to battery from the motherboard, and left it unplugged for about 20 mins. I also pressed the power button for 5 seconds while it was unplugged. I then plugged it back in, and made sure the plug was correctly seated, put the cover back on, and plugged in the adaptor. to my horror, this did not fix the problem, as it did with friend's MB. Now the light on the charger was flashing from green to orange, and there was a sound like a hard drive spinning, also the status light on the front of the computer was flashing white. So, I opened it up again and plugged in the power adapter to see what it was. Actually, it is the fan. Whenever the light in charger is orange, the fan spins, then when it turns green, the fan stops! This is with the computer completely powered off. I tried removing the RAM and reseating it. I have tried unplugging the battery, and plugging the power adaptor in. It still does the same thing. There no response to the power button at all. I tried a number of different key combinations that I found on various web sites, it will not respond to and key combos with the power button. It seems to just be stuck turning the fan on and off for over an hour now. I will unplug it, so it doesn't cause any further damage.
does anyone know of anything else I can do? I cannot afford to call Apple or have it fixed. Usually, I am able to fix these problems in my own.. But I'm not sure what to do now.
Thanks in advance

Can you borrow a power adapter from someone and try that adapter with your machine? That would, at least, solve the problem or eliminate the power adapter as the problem.
If you have an Apple Store nearby, you should be able to get a free test and estimate for repair. It may be something simple, it may be something more complex. But if changing the adapter doesn't work, that's what I would recommend. If it is the adapter you're just going to need to buy a new one - and if you must do that make certain that you order a GENUINE Apple adapter.
Good luck,
Clinton

MacBook Battery Charge Problem - With a Twist

I got a white MacBook in October to replace an ailing iBook. It ran fine for almost five months, with a slight twist that I've been reticent to come on here and ask about.
Problem #1: The battery charging had what I'd call frustrating behavior. The computer would not charge the battery unless I practically ran the battery down to nothing. Usually it wouldn't start charging until 20-30% charge. My old iBook would start charging at about 85%, so I just figured it was some failsafe that Apple was building in to the new system to improve long-term battery life. This frustration continued until today when...
Problem #2: I went to a coffee shop to do some work. I'd forgotten the night before that I hadn't let my battery run down enough to charge it, so the battery was at 35%. Okfine. I'll run it for a few minutes and then plug it in. I wait. 30%, 25%, 20% and whenever I plug it in to test, it won't charge. I run it all the way down to the point where the system automatically goes to sleep. The battery won't charge. I've reset all the things that can be reset, I've reseated the battery, I've turned it off and back on, I let it sleep for an extra amount of time to squeeze that extra bit out of the battery. No beans. The thing refuses to charge.
In system info, the battery information shows that it's completely dead (remaining power at zero across the board, not the negative numbers I've seen reported in other threads). The power information recognizes that it's a battery with 0% charge, but only says "Calculating until full..." Given that it won't charge, it's going to be calculating for a very long time. The battery flashes one light when I press the button.
I'm going to take it in to an authorized service whatsit on Monday, but in the meantime, what is it likely to be? I've seen answers ranging from bad battery to faulty motherboard. Is there any step I've overlooked to try before resorting to a trip to the store?
Thanks in advance.

Yeah, if it says your battery is only at 18% of it's charge after just a few months, then there is definitely something wrong with it. They will probably give you a replacement battery, considering it is still under warranty. My iBook (2 Years Old) is down to 29% of it's original charge capacity, so I am in need of a new one myself :\
2 Years is what Apple says is the average life span of a laptop battery.

Macbook air camera light flashing on resume?

Hi guys, my Macbook air (11 inch, mid 2011) has recently had its facetime camera light flashing on resume when I open the macbook lid. The time period when it flashed varies, but I am worried about security, and if someone has access to the camera.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
Here's a summary of what you need to do, if you choose to proceed: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a couple of minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know your password, or if you prefer not to enter it, just press return three times at the password prompt.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line "[Process completed]" to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report your results. No harm will be done.
8. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

What do white and orange battery charger lights signify? [presario cq62-214nr]

Just next to where the AC battery charger plugs into my Presario cq62-214nr there's an LED light that changes color, and may remain on continuously, or flash, in different ways at different times.
Here are some of the ways in which the lights display:
- white light continuously on
- white light flashing on and off every two seconds
- white light on for one second, then orange light on for one second, then this sequence repeated [in other
words, alternating white and orange lights flashing]
- orange light flashing on and off every two seconds
Could someone tell me what these different LED signals mean? And also, if there are other LED signals that are possible, but I haven't mentioned them, I'd be interested to know what they mean, too.
Thanks.
Ralph-In-Iowa

No, I didn't charge it a lot in the past.
After several hours the charger light didn't change to green. So I finally called Apple explaining my problem and they told me that if I re-calibrated and resetted the SMC without results then the battery should be faulty. Now I have ordered a new $139 battery from the AppleStore (taxes included), I hope once it get's here the problem will be solved, otherwise I will literally through the laptop though the window!!
By the way, they told me that I'm not elegible for AppleCare so I must buy the parts by myself.
My order still says "not yet shipped", how long will it stay before changing to "prepared for shipment"?
Thanks

Pavilion g7 charge light flashing

I noticed this morning that the AC light on the side of my laptop was flashing orange, I searched google and a few forums said that it could be the AC charger, I have another Hp Probook that uses the same charger and tried with that one and had the same results, so now I am wondering what is going on? I started this morning, since the light was white yesterday, also when I power it on, the battery status on Win 8.1 says "Plugged in, not charging", could it be related to the battery going bad?

The flashing power led is a hardware diagnostic indicating that the battery is faulty.
Does the battery charge enough to use when the notebook is turned off?
Is your notebook still in warranty?

MacBook Battery charger

I just brought a brand new battery charger for my macbook because the previouse stopped working ( it was less then a year old). The new one I recentaly brought a month ago just stopped working and smells of burning plastic at the transformer. Are they covered under the one warranty as well?

As far as I know, only the battery has a limited warranty. Anyway, bring them both back. In my opinion, it's ridiculous that a charger stops working within a year if you treated it well, and you should get free replacements. If you like, you can sell the spare on eBay.
It might be reassuring for you to know, that the MagSafe power adapter has a number of problems that are somewhat known:

Macbook not charging - light remains green. Do I need a new battery? (CoconutBattery specs inside)

Hi everyone,
I just got back from a two week vacation to find that my black Macbook isn't charging. When I put the charger head into the laptop, the light remains green, and the battery isn't charging. I ran a CoconutBattery diagnosis on the machine and got these results:
http://i.imgur.com/mMobh.png
I'm not exactly clear on how to interpret these results, but I believe it's saying that the battery doesn't have any capacity for charging. Will buying a new battery solve the problem? I'm not sure if Apple sells the batteries for the older Macbooks now, either.
Thanks for any help!

Black MacBook battery charger question.

Can I use the charger from a 2009 MacBook Pro on a 2006 Black MacBook Pro? I'm having trouble charging the battery on the MacBook and now think it might be the charger (I've already replaced the battery, reset the SMC, and run he battery update). The specs on the chargers themselves are very nearly, but not quite identical.

but my battery is still working fine
I'll be you anything it's not. With that many cycles it's not uncommon for weird things to start happening regardless of how well it performs. I would look into getting a new battery as well.
Have you reset the SMC?

Macbook Battery Charger Overheating

Hey y'all, my charger for my black macbook overheats when I use it and it smells like something is burning inside. any ideas what may be causing this? Will it damage my computer?

i would SERIOUSLY recommend you stop using it and give apple support a call, that can probably mess with your computer because if your charger is not working properly the circuit that keeps the voltage in a regular level for a computer might be affected and give your computer a high voltage and it could be the end of your laptop.
