MacBook Power in Japan ???

My daughter & her boyfriend are off to Osaka, Japan with his new MacBook in a few weeks.
Power over there is 100 volts, and 50 Hz in some parts of the country, including Osaka, & 60 Hz in others.
Any warnings about how to use or not use the MacBook power supply to protect it from possible harm ??

I guess you have nothing to worry (at least for the magsafe), since it built for those voltage range 100 v to 240 v and 50 hz or 60 hz.
Just use proper socket adapter to connect it to their native power outlet if it differ.
Good Luck.

Will I need a converter/adapter for my Macbook Pro in Japan?

I'm currently set to study abroad in Japan, and I have a few questions about what converters/adapters I'll need. Regrettably, I need to admit I'm not very tech-savvy, making this issue a bit more complicated for me.
Electricity in Japan runs at 100 volts and 50 hertz, and most (if not all) outlets only accept 2-prong plugs, according to the predeparture information I was provided with.
I should note that I lost the "plug" attachment of my Macbook's charger, meaning I have to rely exclusively on the 3-prong extension cord to plug my Macbook in. Needless to say, I should definitely get an adatper to be able to plug the 3-prong charger into Japan's 2-prong outlets.
When it comes to voltage and frequency, though, I'm essentially clueless. What converters and/or adaptors will I need to use my Macbook Pro in Japan? Are there any converters/adapters available that can address both my 3-prong plug and volts/hertz issues in a single product, or will I have to buy a separate product for each of these needs?
Thanks in advance.

You can purchase a wall outlet plug adaptor by purchasing any international travel kit such as Apple's or from AAA. No other device is needed. The power unit for your computer is auto-detecting/switching.

Is it ok to use the other macbook power adapters with the mb air?

I have a few extra power adapters for the Macbook Pro and Macbook. Does anyone know what Apple officially says about plugging one of those into the Macbook Air? I've heard rumors that it's risky and might void the warranty, but I would like to see a direct quote if there is one.
I know those other magsafe plugs are impossible to use if you keep the MBAir on a flat surface, but it's definitely convenient to use a spare Macbook Pro / Macbook power adapter if you put your Air on a laptop stand, or even on a book.

I think we are mixing terms here.
I believe the Macbook Air, Macbook and Macbook Pro power adapters are 45W, 60W and 85W respectively. The power adapters don't push power to the notebooks, the notebooks draw power from the power adapters, Consequently you can always use a higher wattage adapter.
The Macbook and Macbook Pro use different voltages but all the power adapters seem to be able to use each. The Macbook Pro uses 4.6A (amps) and the Macbook uses 3.65A and the Macbook Air 3.1A. Pushing to many amps to a device would ruin the unit, but it seems like this has been planned as you can mix and match all the magsafe adapters today and they all function properly.
I have read that the notebook knows whether it can draw enough power to recharge the battery or only enough to run the computer while it is on and that in the latter case it will charge the battery when the notebook turns off. Whether this is bad for the charger or the notebook is unclear, but since the notebooks seem to respond intelligently in those different situations I think that the apple engineers have planned accordingly. If you draw too much power from the airline adapter for example, the airline adapter will simply stop providing power temporarily and the light will go off for a moment.

Macbook power supply

I just recently purchased a black macbook from the Apple store in Japan. I have a apple travel adapter kit, but what I was wondering is this, can I use my 17" powerbook G4 prong cable with the macbook's magsafe brick? The prong extention cord that comes with the macbook here in Japan only has two prongs.
Powerbook G4/MacBook Mac OS X (10.4.8)

This part isn't rocket science - if it fits, you can use it.
I just switched the cables between my 15" PowerBook and MacBook. They look the same, fit the same, work the same.

Macbook Power Adapter not being replaced

Hi,
My macbook power adapter got burnt first from Magsafe connector end and I stapled it myself and now its burnt from the end where it connects to the adapter itself.
I appraoched the service center but they are saying that they cannot replace the adapter because it is tampered. However all I did was I tried to fix the wires from the magsafe end just to make sure it is well connected and it was a minor issue. Now this small fix is causing me this big cost.
I am worried because the way the adapter is, it got burnt from both end as the cable is so soft and weak that it gets damaged with uses and even if I invest money again there is a good chance that it will get damaged again.
Please suggest. I was in love with apple products but this adapter issue is a big setback. I even started bloggin about apple products and now it seems that I have to tell the truth to people how bad this apple adapter is in deed. Bad experience overall!

Actually, Apple is very good at replacing faulty adapters. It is fairly inexpensive for them to do and to not do so could cause them more serious problems if those faulty adapters should ignite and catch fire.
It seems the most common problem people have with the MagSafe connector is pulling on the cable to remove it. The MagSafe connector is designed to be a safety feature to prevent damage to your MacBook in case the cord is accidentally pulled (someone tripping over it, etc.). The idea being to sacrifice the adapter vs. the MacBook. When removing the MagSafe connector, you should be removing it at the connector itself, not by tugging the cable. The connector is very easy to remove if you simply tilt it either side to side or up/down.
The biggest problem here is your attempted repair. To use a staple to fix a problem such as a loose power connector that, as you say, was burnt is a questionable repair. You really shouldn't play around with items related to power supply. A staple used to hold the cable to the MagSafe connector would have to be VERY close to the connector itself and also like very close to the broken and possibly shorting wires. It is possible that the repair may have caused more damage. A staple in that area and one stapled tight enough to actually hold everything in place could easily short the connectors in the MagSafe.
You really should have brought this to Apple's attention when you had the initial problem. "None of this would have ever happened had Woody gone directly to the police".

Macbook power (charging) adaptor hot

On occassion the MacBook Power (Charging) adaptor gets almost too hot to touch. Any insights ?

That will be a function of the session time it has been connected to the MBP and the electrical power that the MBP has required. I have recorded temperature of 52°c on my power adapter with any noticeable problems.
If you are concerned, place the power adapter on a thick aluminum plate which will act as a heat sink and help dissipate the heat.
Ciao.

Black MacBook Power Adapter

Will the 60W Magsafe Power Adapter currently listed at the Apple Store work with my 2006 black MacBook 3,1?

If that's the same wattage as the one you now have it will be fine (I'm pretty sure all the MacBook power adaptors are the same wattage.)

Will a Macbook Pro in Japan Have different dimensions to a Macbook pro bought in America?

I am in Japan at the moment and bought my Macbook pro with an American style keyboard from Apple Japan's website, so I assume it is an American model.
I now want to get a hardshell case for it. They have the Incase cases in my local computer store here in Tokyo, but I am not sure if they will fit my Macbook or not.

If you bought the Mac in Japan and you are buying the case in Japan it is fairly safe to assume the case will fit your Mac. If you don't like the fit and feel of hte case you can always return it to the store. Apple only changes the keycaps between countires... the alphabet is internal to the MacOS software.
In aticipation of a future question, your Mac will work electrically and charge no matter what cuontry you are in around the world since the charger is a universal power supply... all you need to do is buy a country specfic plug adapter compatible with the electrical socket..

US IBook AC plug adapter into European MacBook power adapter?

Hello everybody,
I have a MacBook white, bought in France, and I would like to use it in the US. Some years ago I bought a power adapter for my IBook G3 in the US, so I kept the AC plug adapter. Do you think it is safe to use the old AC plug adapter with the new power adapter? It looks just like the plugs shown in the Apple World Travel Adapter Kit, but I prefer to be sure. I just don’t want to burn my Mac!
Hoping someone could help…

Perfectly fine. It's a standard connector that Apple hasn't changed in years. It's an extremely simple passive connection with no electronics. I've been freely swapping the adapter plugs from iBook, MacBook, and iPod power adapters.

MacBook Power Consumption

We operate tens of macbooks at our campus for student loans. We are trying to cut on the power consumption of the loans operation. I am interested to know how much power does the power brick consume when:
a) nothing is connected to the MagSafe jack.
b) the macbook is fully charged and the LED is lit green.
Please don't guess or think! give me a firm answer if you know. I appreciate that!

I pulled out my 1940s era General Electric Wattmeter. This is a two-coil instrument that measures Vrms * Irms * cos( phase angle) = actual Watts. This type of meter does not measure reactive power that does not deliver energy to the load but circulates in the system. Reactive power is a concern because the out-of-phase current of reactive power does cause energy loss (I squared R loss) by heating the wires carrying the current.
Power brick energized, but not attached to computer - unmeasurable.
Power brick energized, attached to computer, green LED on - about 0.7 Watt.
Power brick energized, attached to computer, OSX booted, but idle - 8 to 10 Watts.
Power brick energized, attached to computer, screen saver running - 8 - 12.5 Watts.
Power brick energized, attached to computer, 5th Element DVD playing - 12.5 -15 Watts.
Power brick energized, attached to computer, Grapher, contours.gcx - 18.5 - 20.5 Watts.
Once in a while, I could get the MacBook to peak at about 25 Watts (averaged by the mechanical dynamics of my meter) of power consumption. The initial plug-in of the power pack to the socket also consumes several amps for a split second - too hard to measure accurately with my crude equipment. There's also a little audible crack! as the prong touches the outlet, so it is obviously a pretty large momentary in-rush of current.
When the power brick is unplugged, the Irms current draw is about 22 mA according to my Fluke 8060A. Presumably that's almost all reactive at close to -90 degrees phase angle relative to the voltage. Switch mode power packs like the MacBook's tend to be capacitive loads. That's about 2.64 VARs of reactive power.
When the MacBook is idling at about 9.5 Watts of real power consumption, the current draw is about 245 mA. The real power corresponds to about 70 mA of in phase current. This gives the surprising result of about 234 mA of lagging reactive current.
In terms of what real-world thing can you do? For 10 to 100 MacBooks, I don't belive it is worthwhile to do anything. Probably remediating the power supply to reduce the reactive current load would be good thing. At industrial scales, factories worry about current phase angle a lot. Power providers bill for reactive current they have to generate, otherwise they would lose revenue by heating their transmission lines, but the customer gets no energy delivered to the manufacturing process by the out-of-phase reactive current.
Probably, the energy consumed and eventual environmental waste generated by remediating 10-100 power supplies, not to mention the engineering hours required, would not offset the power that would be saved over the useful life of the MacBook.
On the other hand, grumbling at Apple to contract with the manufacturer for a greener design for the power pack for the many thousands of users would be a good thing on which to expend a little energy.
PS: just to be sure my Wattmeter is giving reasonable results, I plugged in a "60 Watt" bulb that's been used for about 200 hours. According to the meter, it draws 58 watts.

Macbook pro retina japan change

Hello, 5 days ago I bought a Macbook pro retina 13 inch and I just check that apple release a new one model for the same price, so it will be possible to change for the new one model if I am in the 14 days of refund? I bought in the Ginza apple store and I'm living in Japan so It will be possible do in the same store?
Thanks for your help

this really helps!

you have to basically minimize all programs besides iphoto (or etc) and system preferences

Very strange macbook power behavior

Hi!
I have a white macbook CoreDuo 2G.
A week ago the light from the power adapter's magsafe connection went off and the computer stopped getting power.
A few hours before this, I had a very minor incident. Some tea got spilled on the table and reached the bottom of the computer. Only the plastic case was wet, I removed the battery and everything looked very dry inside. However, some minor drops reached the connectors, but I quickly wiped them.
The laptop worked fine for a few hours, before I noticed the magsafe's light off.
I've tested the power adapter and the battery and they worked fine on another computer. Then I changed the magsafe board connector (from inside the macbook) with a new one.
Now the macbook has a weird power "behavior":
- When I connect the magsafe with the battery inside the laptop, the computer gets no power.
- If I remove the battery, the light turns green. If I put the battery back, it will charge normally.
Basically the power doesn't get to the computer unless the battery is removed when the magsafe is connected.
Like I said I tested the battery and, beside the fact that is at 60% capacity, it works fine on another computer.
Do you have any idea what can cause this and how can I fix it?
Thank you.

Something new just happen. I have a big X in the battery icon.

MacBook Pro and aluminium MacBook power query...

Hi Guys,
I have a 15in MacBook Pro and my wife has a 13in aluminium MacBook. The power supplies are rated differently but is there one that will charge both? For example will her power adaptor charge mine safely?
We're trying to reduce the clutter on our desk, so one less power cable would be welcome!
Cheers for any help!
HNY
Rich

Hiya,
there is a *firmware update* for older macbooks; if your wife has not got the 2007/8 one, have a look on this *general LIST* . This then enables you to use the new power adapter on both machines.
Do ensure to read all documentation prior to installing the firmware update if you need it (the notes will be attached to each relevant download).
Hope that helps.

Macbook power adapater with Macbook Pro...??

Hi guys,
So I just got home for the holidays and realized I forgot my power adapter for my *Macbook Pro*. However, my dad has a Macbook. I know they're not the exact same adapter, but is it a problem if I use his adapter with my laptop?
Thanks!

If the battery is fully charged it will power it (or if it is not running it will charge it a bit slower than normal) e.g. the 60W will be enough to do one or the other.
Search here for the other 1000 times this has been asked.
Lower wattage = charge or run not both, higher wattage = both and in the case of a MacBook with a Pro adapter, it won't catch on fire (which is a common theme as people confuse power adapters with light bulbs in terms of power consumption).
Searching google will come up with 10,000 more confirmations of this.
