Macbook Air - Mega Sage Power Adapter is warming

I need Help

Here's a statement from an apple article:
The power adapter may become very warm during normal use. Always put the power adapter directly into a power outlet or place it on the floor in a well-ventilated location. If you are using your MagSafe adapter in a poorly ventilated area, or if the MagSafe adapter is covered by a blanket or other form of insulation, it may turn itself off in order to prevent damage to the adapter.

Charging MacBook Air with older power adapter.

I have just bought MacBook Air. I still own the MacBook Pro 15' dated 2006. Can I use MacBook Pro's power adapter to charge safely MacBook Air?

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 Air won't power up after update

My son is on an internship in Alaska with his Macbook Air -- bringing the Macbook Air in to a "Genius" is not an option.
His Macbook Air (about 2 years old) has been working perfectly, but then this morning Apple pushed an update so he downloaded and applied it and now his Macbook Air will not power on. At all.
Is there a reset hole / button or anything he can do? Or is he just out of luck for the next several weeks until he comes back?
I cannot tell you which release the Macbook Air is, given that he cannot power it up to see, but he, like all of us, is running the latest OSX.

Thanks to Loner T and others in that thread I linked to above, my son's Macbook Air is now working again.
Doing the following 3 times brought it back:
1. Shut down the computer.
2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected
3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time
4. Release all the keys and the power button at the same time
5. Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Hi, my MacBook Air is not working anymore if it's not connected with the power cable. It's pretty new so I can't imagine that the battery is dead already. Why can't I use my MacBook Air without the power cable even though I charged it for hours?

What is the best way to connect macbook air to present power point presentations

What is the best way to connect macbook air to present power point presentations

Since you posted in the Thunderbolt Display Community, I am guessing you are attempting to connect a MacBook Air to a Thunderbolt Display, but since you tagged projector, it makes me doubt my assumption. Can you provide some more details on what you are trying to connecto your MacBook Air to?

Using a MacBook with ONLY a Power Adapter

HI!
is it possible to use my MacBook with just the power adapter? The current batter and adapter are both dead, and I'm pretty low on cash. So I was thinking I would purchase a new adapter in Amazon. Thoughts? Thanks.

Yes, you can use it on just the power adapter, without a battery installed.
There is a significant performance decrease when a functional battery is not installed, but it will still work without a battery, just not as fast.
Here is one of many links on the subject:

HELP! My Macbook Air won't power on!!

I have plugged it up and the power cord's light is green. It has ben a week and it still won't power on. What do I do now?

Were you able to find a solution... My wife's Air is doing the same thing I have tried all the KB suggestions of key combinations etc.. The power supply is green but the Macbook Air will NOT power on. Frustrated because I have a Dell laptop and never have had any problems as this Mac. So far she has had the Hard Drive fo so we replaced with a SSD $145... Then the hinges went $150... Then the LCD went $150 now it will not power on... from the looks of things it could be the Logic Board $850. There is no way I am sinking more money into this inferior product... I think Apple should be replacing this free of charge...This was all after the warranty was up...
Let me know if your problem has been resolved...

MacBook Air Thunderbolt-to-FireWire adapter and daisy-chaining external FW drives

Here is my problem—I have a MacBook Air 13" running Mavericks to which I want to attach external FW drive(s). This is easily achievable by using the Thunderbolt-to-FW 800 adapter. And the adapter works great until I try to daisy-chain two external drives. If I attach a second drive to the first one, it immediately unmounts the first drive and I get the 'improperly disconnected drive' warning.
I seem to recall that this was doable in Mountain Lion (about 85% sure). So is this a software or hardware problem? And, to go even deeper into the weeds, my two external FW drives are self-powered (no external power supply). So if I got wall warts for these drives, would it work? Or am I remembering this incorrectly and the adapter never supported daisy-chaining?
The external drives are a pair of G-Tech G-Drive minis, but one is a year to 18-months older than the other one, which means it probably has an older FireWire chipset, but on the other hand, they do mount successfully as self-powered FW 800 drives from a native FW 800 port, or even from a daisy-chain originating from a FW 800 port. Anyone have any suggestions?

I have 4 FW devices chained together and use the TB->FW dongle. They all have power bricks. I have several bus powered devices. Some are quirky, some just don't function, two work reliably. There's no question it is all about how much power they need and TB doesn’t supply enough. Bottom line for me: my bus powered FW drives are soley relegated to use with my last FW equipped computer and when it does they will too.

My Macbook air is "burning" power adapters

I've owned my 13" macbook air for a couple years now and never really had an issue. Until a few months ago, I noticed my computer right where it gets plugged in was getting extremely hot, to the point where you could actually burn yourself on it. When you look at the power cable and the actualy plug in the side of the computer it was actually charred brown and black.
I've since bought a new power adapter and it lasted a little while until the computer burnt it as well and it no longer worked. At this point i've got a new power adapater and it hasn't charred anything, but the only way to charge is to now have a book under the plug to force it upwards and then it will actually charge. It basically makes the laptop immobile and it has turned into a desktop computer at this point. Very frustrating. Unfortunately myapple care ran out so i'm left a bit stranded. I believe, now, i'm either looking to replace the whole power plug in the side of the computer or just live with a overly expensive/relatively slow desktop computer.
Any tips or suggestions or recommendd solutions would be a massive help!
Thanks!!

Welcome to the Apple Support Communities
First, reset the SMC > http://support.apple.com/kb/HT3964 If this problem is related to software, this should fix this problem.
If it doesn't work and you can start your computer, open System Information or System Profiler (it's in /Applications/Utilities), choose Power in the sidebar, and copy here "Charge Information" and "Health Information".
If you can't start the MacBoook, the only thing you can do is to take your computer to an Apple Store or reseller

MacBook Air will not power on after going to sleep

I have a 13" MacBook Air (2012) that has been giving me some issues on and off lately. The past month or two, it has had a few instances where it would take a lot of time and work to get it to "wake up" after the lid was opened. A few times I had to hold the power and reboot it as it was non-repsonsive and would not display anything on screen (black screen). Then a few weeks ago it was un-responsive for a minute upon opening the lid but I eventually got it to come alive but it was very slow to get going as there were quite a few programs running and it auto-rebooted itself. Once I logged in, it did it again but this time it got hung up on the apple logo on boot and was in a cycle of trying to reboot itself but failed at the apple logo. I eventually got it into recovery mode and went into Disk Utility. It found some problems with the hard drive and fixed them. After that, it booted up fine and hasn't given me any problems UNTIL... yesterday, it won't even attempt to power on at all. It was working fine yesterday morning and I was only using Safari (no other programs running) then I closed the lid and left for a few hours with it just sitting there. I didn't take it with me, drop it or anything like that (In fact, it's never been dropped). I just left it right there where I was using it and closed the lid. I came back in the afternoon and opened it up and waited for it to come on but nothing happened. It wasn't even powered on as I put my ear up to it and listened for noise. I've tried holding the power button, I've tried Option+Power, I've reset the SMC, but nothing happens. I don't know what else to try. I believe this model may have a recall on the solid-state-drive but I'm not sure that is it as it should at least power on and display a folder with a "?" mark if the hard drive was bad. I'm wanting to attempt to resolve this before I make a 1.5 hour trip to the Apple store so any help and suggestions are welcome.
Things you should know:
It successfully resets the SMC as the orange light flashes green for a few seconds before turning orange again.
I've tried the charger with 2 different plugs with and without the extending cord. I've also tried booting on battery power only.
The power button is not broke as it recognizes it while doing the SMC reset.
Thanks so much for all your help, Silas

does the little light on the mag safe dongle turn green to indicate it is charging?
Are you sure you mean green? Mine is orange when charging and green when fully charged - always been like this with the 3 macbooks I have owned.

Does my Macbook Air need a power converter in the UK?

I am traveling to the UK soon - will I need a power converter for my MacBook Air, iPad and iPhone?
thanks

Input voltage for iPad and iPhone is same. 100 -240 Volts.
You will need plug adapters for those power adapters.
No converters are necessary.

13" MacBook Pro w/ 65W power adapter.

Are the 65W power adapters for the 13" MBP sensitive to power fluctuations? Mine is not working at my inlaws (rural area) but seem to work at home in a more urban area.

Every power supply has input power quality tolerances.
If yours works in one location but not another, then the input power is not within those tolerances.
This excerpt from Troubleshooting MagSafe adapters may be applicable:
Identify line noise issues.
Unplug the power adapter from the wall, let it sit for 60 seconds, then plug the adapter back in.
If the adapter works after this 60-second "rest", you most likely have a line noise issue with your power source. You should reset the adapter periodically by repeating this moment of rest. This issue occurs when the AC adapter's "over voltage protection" feature senses ground noise and then turns off the adapter.
Some possible sources of line noise include lights with ballasts, refrigerators, or mini-refrigerators that are on the same electrical circuit as your computer. This behavior may not occur if you plug the power adapter into an uninterruptible power supply (UPS) or plug it into a different circuit.
Unless the adapter continues to exhibit this behavior on a known good outlet, it does not need to be replaced.
