Charging New MacBook Air

All wattage ratings aside, will using a 16.5 volt MacBook adapter damage the batteries in the 11" MBA? The output of the 45W adapter that came with it applies 14.5 volts.

I also wondered about the voltage difference between MBP 60w+ adapters and the MBA 45w adapters.
Note that the article also states (it was updated 2/2011, since your last post) that:
Note: Adapters that shipped with the MacBook Air (Original), MacBook Air (Late 2008), and MacBook Air (Mid 2009) are not recommended for use with MacBook Air (Late 2010) models. When possible, use your computer's original adapter or a newer adapter.
newer adapters should power and charge your MacBook, MacBook Pro, or MacBook Air just like the adapter that originally came with your computer
indicating backwards compatibility between newer adapters and older computers - but not necessarily the other way around, nor universal compatibility.
So I'm wondering how safe it is to power the Late 2010 Macbook Airs from older Macbook Pro adapters...

I bought a new MacBook Air the other day and I have been trying to connect my iPhone into the laptop to charge. However every time I plug it in, the phone connects and disconnects very quickly and doesn't charge. How do I fix this?

I Bought a new macbook air and it won't charge my phone. This is the second laptop ive gone through as i got a replacement one only two days ago for the same problem. I need to be able to connect my iPhone so I can download songs etc from iTunes onto my phone. How do I fix this?

Since this is the second computer you've had this problem with, I recommend you look for answers on the iPhone forum. My thinking is it is an iPhone issue rather than a computer issue (unless it is some software incompatibility).

Brand New MacBook Air Won't Charge

I just bought a new Macbook Air 1.8 GHz (the more expensive version) and from the second I opened it, it would not charge. The only way I can use the laptop is if it is plugged in. When I look at the computer's info, it says BATTERY INSTALLED: NO CHARGING: NO CYCLE COUNT:0
What happened? Was it supposed to come with the battery installed? Should I send it back?

if the store is close take it back and ask for replacement, otherwise call and ask for replacement
you could call support and get it fixed under warranty...
U.S. iPod and Mac technical support: 1-800-APL-CARE (1-800-275-2273)
...but if it is brand new you have a reasonable expectation to get what you paid for, so going for replacement is the beter option

Can i use a 85 watt charger with a new macbook air

Can i use a 85 watt charger with a new macbook air that comes with a 45 watt charger. One says its 14.8 volts and the other is 20 volts.

To be clear, the wattage of the adapter is not the power delivered to the Mac, but rather the power the adapter is capable of delivering.
Think of it as the difference between a 200 HP and a 400 HP engine; both can drive at a certain speed with no issues, the difference is what happens if you floor the gas pedal.
The same is true between the higher wattage power adapter that comes with the iPad and the one that comes with iPhones; you can use the higher wattage adapter to charge and iPhone with no issue, but if you try and use the iPhone adapter to charge the iPad it may work, but it will take much, much longer.

Adaptive charging in "new" macbook air?

Hi,
I've seen many peoples wondering about the new macbook air's battery.
But didn't clear me up.
So I'm still wondering about the adaptive charging used in the macbook pro's.
Does the new macbook air have adaptive charging or not?
and if so, are they functioning as the macbook pro?
Because in one of those topics someone asked the same stuff, and the answer was: "type=yes, Size=no"
So the new macbook air series are will adaptive charging chip, but are they functioning with 1000 charging cycles?
I'd understand that the mba won't last for 7 hours or anything like that as the macbook pro, because its not a battery with the same quantity cells, cuz the mba uses a lil bit smaller battery.
Anyways, I just want to know if the new macbook air series are built-in with adaptive charging, and if they are functioning.
Thanks

I cannot be absolutely sure - except that when the latest revision of the MBA was released - Apple never announced that feature in the battery - and - they really made a big deal of it last fall when they released them with the MBP.
So - I think they didn't mention it because that technology is NOT in the MBA.
If it was they would flaunt it to sell more MBA's.

If I buy a new MacBook Air will the Apple Store help me transfer everything from my old MacBook Pro?

Will Apple help to copy over all the settings, apps, programs, files, etc. from an old MacBook Pro 15" on OS X 10.6.8 to a new MacBook Air 15"? Will it work easily and painlessly? Will they help me set it back to factory once everything is copied so that it can be sold or given to someone else? Will they charge for this?
I want to get the new MacBook Air 13".
The current 15" 2.53 GHz MacBook Pro Mid 2009 has the following specs and OS:
Mac OS X version 10.6.8
Model Identifier: MacBookPro5,4
Processor Name: Intel Core 2 Duo
Processor Speed: 2.53 GHz
Number Of Processors: 1
Total Number Of Cores: 2

According to Apple's serial number identifier it's this: https://support.apple.com/kb/SP544
Thanks.

You sure about this? https://www.apple.com/why-mac/better-support/
"Purchase a One to One membership at the same time you get your new Mac from an Apple Retail Store, and you won’t have to spend hours transferring all your stuff. Just bring in your old PC, and we’ll do it for you. A Specialist will move all your files — email, contacts, music, photos, documents, calendar, desktop items — and make sure everything is exactly where it should be. One to One costs just $99, and it includes a year’s worth of one-hour, face-to-face training sessions. It’s like getting a head start before you start."
This is really disappointing. Buy a $3,000 computer from them and then buy another one for $1,000+ and all they want to do is screw you over, nickle and dime you and price gouge you on setting it up.

My new Macbook Air hard drive gone bad

My new macbook air hard drive just died on me last saturday while I was working on my paper. With that I've lost all my files. I took it to Apple store, but I was told that all they can do is to replace the hard drive for me.
I'm not really happy with the service. You pay so much more to get your money's worth. I was suggested that if I wanted to retrieve my files I had to take it to an outside source for about $500-$700. It's like buying a defective device that causes you some nasty injury and when you ask for their part of responsibility they tell you to take a hike.
I wish there was a law that would be more protective of people's time and (intellectual) property as opposed to leaving us to the mercy of, ultimately, the greed that drives these companies.

Fellows,
Please don't read my e-mail with your emotions. I have nothing against Apple other than my disappointment in this particular service that I received. I can make a long list of all the good things that Apple has brought in this world.
My point is this: whether Apple or a PC, when you buy a brand new computer, the manufacturer should not only replace the failed part (in my case it did, as is the norm in the industry), but TRY to retrieve the lost file(s), when is applicable, free of charge, during the warrantee period.
Does it make sense? I find this a very reasonable request/demand. Remember that, according to Apple representative, an outside source was potentially able to retrieve my files.
As a customer, I want to have a better service, especially when I pay more for the promised quality.
If we customers were happy with what is offered/or not, then we would have still worked 70 hours per week, our cars didn't a seatbelt, and ...
I hope this helps to clear my argument.
Cheers,
I understand where you are coming from, however, there is nothing that they can do. If the drive has been damaged and does not work, then there isn't anything that they can do. When those other places charge the prices that they do, it's to pay for them having to physically remove the platters from the drive that you currently had, and keeping every tiny spec of dust off them as a spec of dust could render the platter useless if it gets caught between the heads and the platters. This being said, they would then have to take those platters and place them in a new drive basically. Most people understand that there is nothing that can be done when something like this happens, they have external drives and they backup all their data. I have mine backed up on two seperate drives and in a remote location away from everything here. Let's put it like this, say you bought a house, and then you put a lot of your memories and things and whatnot into your house, say pictures, papers, things like that. Now your house burns down, would you expect the people that built your house be responsible and demand that they somehow get your pictures and things like that back from your house that were burned up? It's kind of asking the same thing that you would get if you were to demand that they somehow magically make your drive start working and get the information off it.

Problem - new MacBook Air cannot see external HD

Hi, I'm hoping someone can help, as I have seen similar questions in the forums, but not with an answer that helps me solve my problem.
Ok, I have a new MacBook Air running Lion (bought last year), a MacBook Pro running Leopard which is approx 4 years old and a Windows Laptop. I use the MacBook Air for Work and when travelling (weekly with work), the MacBook Pro for home and managing my other apple devices (iPad/iPhone etc..). I no longer use the PC, but there are loads of files both work and home, I wish to keep on an external HD for use with both Apple Laptops.
So, the external HD used to work with the MacBook Air when I first bought it (a couple of weeks ago) and formatted it with the MacBook Air, but it couldn't be seen or used with the Windows PC. When I formatted it with the Windows PC, I could use it with the MacBook Air but could not write to the disk.
So I have now partitioned and formatted it with the MacBook Pro running Lion, but now the MacBook Air cannot even see the disk in Disk Utility.
My MacBook Air otherwise runs absolutely fine with no problems, and the MacBook Air is a critical piece of kit that I use on a daily basis to do my job. As such, I have no appetite for deleting any drivers etc... from the MacBook Air as it could originally see the disk and I do not want to make a mistake and cause myself problems.
So the question is, how on earth do I get the MacBook Air to see the drive again in Disk Utility? So I can do the partitioning and formatting there, this drive is of no use if can only be seen by the MacBook Pro. The drive is a portable USB powered Toshiba 1TB disk Part Number: HDTB110EK3BA.
Am going to wait for some suggestions, my next thought is to erase everything using the windows PC assuming it can see it, and then see if the Mac Book Air laptop can see it in Disk Utility... no other options left really.
I hope someone can help, otherwise I may be off to buy a new disk and could hit the same problems again!
Thanks
Alex.

Toshiba Acknowledges MacBook Woes in Canvio USB 3.0 Hard Drives
By Christopher Price on December 27, 2011
Following tests conducted by PhoneNews.com, Toshiba has acknowledged an issue affecting their Canvio USB 3.0 hard drives. The issue prevents current-generation MacBook Pro and MacBook Air models from properly connecting and powering up the drives.
Read more to see our findings, and the resulting (ongoing) investigation by Toshiba.
We began our tests based on tips from readers like you, and went out and purchased five (yes, five) Canvio USB 3.0 drives, along with a brand new 2011 MacBook Air.
Drive problems happened immediately, and were relatively isolated to the MacBook Air. Of all the systems we tested on, we were only able to reproduce issues on a Sony VAIO laptop late in our testing, as well as a current-gen MacBook Pro.
Essentially, the drives failed to mount, and in most tests never even spun up on these systems.
The Canvio USB 3.0 hard drives have sat under many people’s Christmas trees, as they were hot sellers during Black Friday. Retailers like Office Depot slashed prices on the slim, 2.5-inch drives down to $79 for a 1TB hard drive. With coupons, Radio Shack was selling the 500GB model for a mere $39.
Canvio USB 3.0 drives tout on the box compatibility with USB 2.0 systems, including both Mac and PC. The advantage of a Canvio USB 3.0 hard drive for a MacBook owner lies in Thunderbolt. Purchasing such a drive today can achieve USB 3.0 speeds with upcoming Thunderbolt-to-USB 3.0 adapters. USB 3.0 mass storage was designed to be fully backwards compatible with USB 2.0.
To get to the bottom of the problem, we probed the five Canvio drives purchased, in an effort to better understand the issue. And, we were able to isolate the problem; the Canvio USB 3.0 drives draw more power than the USB standard permits. The drives were drawing, upon connection, slightly more than the five watts that the spec allows. And, the new MacBooks appear to promptly shut the device down because of this.
Why? Well, Apple can assert that this is to protect the MacBook Air/Pro from a malfunctioning USB device. However, the answer really lies in tablets. Apple allows iPad and MacBook to perform a hardware handshake, which then allows Apple devices to draw 10 watts from the USB port. This is why you can charge an iPad directly on a Mac, but not on a PC.
Apple does not want to allow rival tablet manufacturers (Android) to have the same access to Apple’s USB port. Hence, any device (like a tablet) that wants to draw even slightly more than five watts, is shut off from communicating with the Mac. We affirmed this by testing a powered USB hub. With a powered hub connected to the hard drive, and the hub connected to the MacBook, the drive instantly came to life, and worked without issue.
This creates a bit of an odd situation; Toshiba is technically in the wrong for making drives that technically breach USB specifications… but Apple seems to be the only manufacturer to enforce this aspect (as well as breach it with their own devices).
Toshiba, to its credit, has owned up to our issue, right down to our suggestion to them that a powered hub works around the issue. Quoting an official statement in response to our research:
Toshiba DPD has identified an isolated USB connectivity issue between the Canvio USB 3.0 drive and currently shipping MacBook Pro and MacBook Air laptops. The issue involves the MacBook Pro and MacBook Air being unable to recognize the Canvio USB 3.0 drive when connected directly to the laptop USB 2.0 port. Toshiba is actively working to remedy this USB connectivity issue. In the interim, Toshiba recommends MacBook Pro and MacBook Air users employ a powered USB hub to connect their Canvio USB 3.0 drives.
We have asked Toshiba if they intend to inform retailers to accept returns for affected drives, or if they will offer some form of refund program in the interim. Retailers such as Office Depot do not permit refunds on opened technology items, including Canvio drives. Toshiba has said are looking into that aspect of this problem, and will get back to us shortly.
In all, we spent a few hundred on hard drives, and confirmed the issue. Unfortunately, because it is a power drain concern, Toshiba will likely have to offer an exchange program to fix it. We seriously doubt that this can be fixed at the firmware level. Theoretically, it’s possible a USB cable replacement might be able to mitigate this issue however, so there is hope that Toshiba won’t have to recall a bazillion hard drives.
Update: As a follow-up, Toshiba has informed us that they have completed their investigation, and will replace affected drives.

New Macbook Air with bad battery life

I've got a new Macbook Air (2013, 11-inch) and I upgraded the RAM and the processor. I'm only getting 6 hours max from the battery, which is disappointing because I wanted to be able to do a day's work without a charger. I've already sent one back and had it replaced, but the new one has the same problem. I've done a call with Apple Support, where they directed me to the help article I'd already read. I've checked Activity Monitor and killed everything I can. I've turned off Bluetooth as well. I use Chrome a lot, Tweetdeck is running, but neither of these things I'd expect to result in a 6 hour battery at 100%.
Does this sound like normal performance? If it's the processor speed, I'd be tempted to return this one and downgrade the processor as battery life is more important to me than speed (my work is mostly online anyway).

Quit Chrome and try Safari for a while. See whether there's an improvement.

I just bought a new Macbook air 3 weeks ago and now there is out a newer model

I just bought a new Macbook air 3 weeks ago here in Thailand and found out that since 3 days the new ones where lunched. is there a chance to get the new one for no charge? it happend to me with the iphone in the US before and apple changed it to the new model for no charge. But does this service work for Thailand too??

After 3 weeks, probably not, but it's up to you to at least try. If you purchased your computer through Apple's online store in Thailand, there's a phone number you can call. If you purchased the product through a premium reseller (iStudio, for example), you should take it back to the store. If you purchased it from a dodgy storefront in Pantip Plaza, or MBK, you can always ask...but, I'm guessing that they won't help.

New MacBook air and Iphone 4 won't connect via CABLE

Hi, hoping someone can help.
I bought a new MacBook Air a few days ago however when I insert my USB cable to connect it to my Iphone 4 to sync to my Itunes it will not recognise or charge the device, let alone sync. It simply flickers between charge and not charge so seems to be connecting for 0.2 of a second then goes off instantly afterwards- which allows many warning notices to appear on my macbook air. I have no idea what to do and I cannot even sync to Itunes.
My Iphone still works and syncs with my other PC and the cable is in good working order......
Any response would be fantastic.
Regards

If the phone still syncs to the other computer and you are using the same cable then the problem must involve the computer. Try performing a reset of NVRAM and PRAM.
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

New Macbook Air 13" battery questions?

I just got my new Macbook Air 13" i7,8gb Ram/512GB SSD last December 25. I just came to notice after fully charging and using it (straight usage, no powering off doing installing, learning, etc... beacause I'm new to Mac ), It doesn't reach 12 hours, maybe it took 6 hours Max to recharge again on 10%.
Is it normal for a newbie? or it should be really 12 hours usage in reality?
Please advice.
Thanks in Advance..

12 hours quoted is the result of testing the battery under lab conditions.
Battery runtime will be lower when battery is under real life conditions.

My New Macbook Air :(

I have just converted from window pc to mac. I got my new macbook air on 21 October 2011, the first day I charging my macbook air I could feel the a light electrical current in my hand, it's serious and horrible. thus, I have contacted apple shop, and they told me it's normal for mac. sometimes, I even got electricity shock, uncomfortable feeling, hate this kind of feeling.
And, I have been to apple shop to do testing on the disply mac there, I realized there's no any mac there has same kind of problem. after telling staff there my mac problem, they said it need to takes one to two weeks for repair.
This problem has spoiled my impression towards apple mac, as a fresh user of apple mac who converted from window pc.
Jett.

The problem is your electrical source not properly grounded. Do a search on 'mac tingle sensation'. You can also do a simple test by getting your feet off the floor while plugging in e.g., try it on your bed. Or, bring your laptop to some other place where the receptacle is properly grounded e.g., the apple shop.

I can't sync my iPad 3 with iTunes using the new Macbook Air

When I connect my iPad 3 with its original cable to my new MacBook Air, the charge symbol in the iPad starts to blink and the iTunes keeps connecting and disconnecting the iPad (more than one time per second).
I can sync my old iPhone 3GS with the new Macbook Air and I can sync both iPhone and iPad with my old 2009 MacBook.
I found similar questions in the forum, but didn't find a solution. I can charge my iPad using the outlet, by I still need to backup and sync the iPad.
BTW, every software is updated.

i have the same problem. I am noy able to connect the iPad3 to my new Macbook Air. It only cycles the charging icon and itunes states the phone has been disconnected.

Battery Leakage? On New Macbook Air 11"

Everything is working beautifully on my new macbook air except for one thing. When plugged into the mains the usage on the battery monitor gradually goes down after about 12-16 hours. When it got down to 98% I decided maybe it needed calibrating with it being new so I let it run down after fully charging, and carry on overnight. Re-charged it up again and the same thing is happening. Down to 99% while plugged in at the mains.
Any advice appreciated

Each computer and battery is unique, even for the same computers. Each battery contains circuitry that controls how the battery is charged, detects what the charge level is, etc. Once the charge level drops to 94% the charging circuitry notifies the charger to turn on. When the battery is fully charged the circuitry tells the charger to stop. Otherwise a battery may be overcharged resulting damage to the battery. However, the connection between the hardware and software sometimes leaves a menubar display showing a battery is 98 or 99% full but never hits 100%. In some cases it hits 100%, but only when the computer is asleep or turned off. I have an older generation MBP that rarely ever shows 100% full. This is not a necessary indication of a battery, charger, or computer problem.
If it bothers you then reinstall OS X in case it'as a software problem, otherwise take it in for service.
