MacBook Pro using power adapter but not charging.

My MacBook Pro is plugged in w/the power adapter, the green charging light is on, but my battery percentage is only showing 15% and is not increasing. It was actually at 60% this afternoon...went to 22% and now is @ 15%.

Could be bad battery or faulty charger or faulty charging circuitry. Take it to an Apple store or AASP.

IPad won't charge using power adapter but will charge via USB

I have an iPad 1 that recently stopped charging using the power adapter. "Broken power adapter or cable" I thought and reached for a spare that I have. That didn't work either. The original power adapter however DID charge another iPad without any problems, so the problem cannot be with the adapter or cable.
Now this is the wierd bit - using the original cable plugged into my laptop I get the usual "Not charging" message but the iPad DOES charge slowly this way.
I rebooted the iPad, restarted it in recovery mode and restored the firmware, cleaned out the 30-pin connector port - all those useful bits of advice that you find on the internet but all to no avail. The iPad just will not charge using any of the many original Apple iPad charger sthat I have been able to get my hands on but will only charge on an underpowered USB port!
The 30-pin connector must work otherwise it wouldn't charge via USB. Can there be some kind of wierd internal hardware defect that might cause such behavior?
I fear that if I take a 3 year old iPad to the Apple Store they might just give me their best smile and show me the latest iPads but this old iPad works fine otherwise and I don't really want to replace it.
Anyone got any ideas?

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
And this - Unplug the charger from the iPad and then replug. May resume charging.
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.

At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

Power Adapter Does Not Charge the Battery and Charge Light Is On?

Power Adapter Does Not Charge the Battery and Charge Light Is On?
My power adapter doesn't charge my computer anymore. however the charge light is on.
Please help my battery is draining fas

So, with your power adaptor connected not only does the battery not charge but the powerbook is not running on ac power. Then I guess the power adaptor is faulty. In as much as you've verified this with a known good one a new one is in order. Try yours in another powerbook to make sure.

My MacBook Pro tells me it's not charging when I connect the charger. What do I do?

My MacBook Pro tells me it's not charging when I connect the charger. Right now it's reading it, but other times it does not. What do I do?

Initiating a charge cycle is a costly and disruptive operation. It is only started when the benefit to battery life exceeds the cost to battery life of a charge operation. That is usually when the battery falls below 90 percent charged.

Macbook Pro Magsafe Power Adapter

Hi,
I recently have bought a new Macbook Pro 13". Will using its charger (model no. A1344) to charge my white Macbook (late-2006 model) damage it? The white Macbook's charger is no longer functioning and I didn't buy a new one… Do you recommend buying a new charger for white Macbook? I just don't wanna end up with a new laptop and a damaged charger..
Thanks...

Power adapters for Intel-based Apple portables are available in 45W, 60W, and 85W varieties. Although you should always use the proper wattage adapter for your Apple portable, you can use an adapter of a higher wattage without issue.
For instance If you have a MacBook (13-inch Late 2009) that normally uses a 60W adapter, you can also use an 85W adapter with that computer. You would not use a 45W adapter with that computer; it would not provide enough power for that MacBook. Using an adapter of higher wattage than the adapter that came with the computer will not cause the computer to charge more quickly or otherwise operate any differently than using the adapter that came with the computer.

Macbook pro 15' power adapter not working

When I was using macbook pro 15' early 2008 this morning, the power adapter suddenly did not work. The led light on the power adapter blanked and the status bar showed that I was using the battery. I am sure about the power adapter is fine cause I try it on another macbook pro and it works well. I have tried to take off the battery and the power adapter for 30 secs and then press the power button. But it does nothing good. I have tried to press the option + command + "R" + "P" and power button to reset PRAM. But the problem is still there. Now I have run out my battery what should I do ?

Welcome to Apple Discussions
It sounds like the power board inside the MacBook Pro has failed, best get it to an authorised repair centre.

MacBook Pro 17" power adapter lights orange when NOT plugged into laptop.

My MacBook Pro power adapter lights up orange even though it is not plugged into a device. When I do plug it into my laptop it remains the same and does not charge. Due to this my laptop is now dead. What does this orange light mean?

You should take both your MBP(Macbook Pro) and your power adapter to an Apple Genius bar or an AASP(Authorized Apple Service Provider) for a free evaluation. This is a strange occurance, and it seems that it may be a hardware malfunction.
Make an appointment so you don't have to wait too long.

Use macbook pro on power adapter or on battery?

Is it recommended to use my macbook pro with the power adapter plugged in or using the battery? how does it affect the battery?

http://www.apple.com/batteries/notebooks.html. i keep it plugged in most of the time. i use it on battery only when i need to, or at least 1-2 times a month.

Macbook Pro Mid-2010 15" is not charging with dim green light

Hi all,
I have spilled a bit of water on the keyboard of my Macbook Pro this Monday. It continued working just fine.
So, I took it home, and 2h later, when I pluged the charger in, the light turned into a very faint/dim green light and it was not charging anymore. It does not consumes battery power, because it's plugged in the outlet, but it does not charge either (says "not charging").
I have tried the following:
Plugging it in to a different outlet
Trying other MagSafe chargers
Making sure it's the correct charger (85w)
Resetting SMC
Resetting NVRAM
I have opened the back, and although I could not dismount it anymore because the lack of appropriate screwdrivers, I could find no sign of humidity or water damage.
Checking the system information page in the MacOS, I could notice that, when the charger is plugged, amperage information gradually progresses from ~ -2000 to 0.
And it does not seem to recognize the charger. See below:
AC Charger Information:
Connected:     Yes
ID:     0x0000
Wattage (W):     0
Revision:     0x0000
Family:     0x0000
Serial Number:     0x00000000
Charging:     No
Do you guys have any other suggestions?

If you are lucky, the power adapter is faulty. I suspect that there are problems inside the MBP. I still advocate a trip to an Apple store genius bar. Your MBP has a hardware issue and they (Apple) can diagnose it and tell you exactly what will be required to repair it.
Ciao.

Late 2008 Macbook Pro: Which power adapter?

Hello all. I have a Late 2008 Macbook Pro 15", MacPro5,1. A few months back my dog ate the power adapter (unplugged, thankfully.) I thought I did the proper amount of research to order the correct adapter from a third party on Amazon, because I'm pretty darn broke and need to save every penny I can. When I got the adapter, the connector was different from the one that came with my Macbook Pro. It was 85W, all the numbers matched up, but the style was different. But, the plug worked enough to let me get the work done that I needed, so it didn't concern me too much.
That is, until this cord just stopped working. That's what I get for getting a third party cable from China off Amazon.
So now, I'm trying to research again to make sure I'm getting the right cable, and I want one that's made by Apple, and is exactly like the one that came in the box when I bought my Macbook Pro new. I went to MacSales.com and checked their compatibility pages, and ran into some issues. What is showing as compatible with my Mac is the 85W Magsafe MC556LL/A, but this is shown with the incorrect connector (like the one I got off Amazon.)
When I looked at the other adapters that were available, I found the MagSafe 2 85W MD506LL/A, which has a connector that looks like the original, but it only shows as compatible with 2012+ Retina Display Macbook Pros.
So, do I have to buy the MagSafe that is not like the original that came with my Macbook Pro, or can I get the MagSafe 2 that does match what I got out of the box?
Reference pages from MacSales.com:
http://eshop.macsales.com/item/Apple/MC556LLA/
http://eshop.macsales.com/item/Apple/MD506LLA/

Thanks! I didn't realize there was a revision, but that makes sense. I guess I don't understand they would change it, then use the original design for the later Retina Display models. Oh well, as long as it works!
On a similar note, is OWC the best option for a cheap Apple-brand adapter? They're selling them for $47, when the cheapest I can find anywhere else is like $75. They seem pretty reputable with all the options and Apple-specific stuff they offer, I just didn't want to make the same mistake again and would like other options if they are available.
Thanks again!

Ask your question.new battery 4 macbook pro 15in....not charging

my new battery is not charging.??... i can only used my "lab top"with help of the power adapter....ANY /HELP ,so i can stop plug in ...mac probook 15in...THANKS

I installed the new one, the MacBook did not recognize it. I thought it needed to charge, but the green light on the power cord came on, so I didn't think that was the problem. In the status bar, the battery shows up with an X in it, and no percentage will display.

Ipad air USB power adapter is not charging

I had to replace my charger twice within the year of having my ipad air in order to get it charging. The first time it happened I went out and bought a new cable (but kept the same adapter the ipad air came with). About a month or so later my ipad was no longer charging. I went out tonight and bought a new wall charger all together (so using a different adapter) and its now charging. I am not sure if this was an issue with the original power adapter or if there is something more going on. Has anyone else experienced this issue?

I don't think it's unheard of. Charging issues can be things with the adapter, or with the cable.
