Electric charge on Macbook Pro casing
I just notice that when I rn my fingers across the casing on either side of the trackpad on my Macbook Pro 17" I can feel a small current passing through the casing. This only happens when the AC adapter is plugged in and charging the laptop. Anyone else notice this? I have searched the posts but could not find an explaination.
I have this issue too, only when I plug in the UAE (Dubai). We have 110V three prong adapters there, and still, it buzzes and sometimes shocks me like a mad girlfriend.
I called Apple Care, added it to my list of issues, and they're sending me a new one. Although some say it's not a problem, it most definitely is. After my MagSafe sparks, battery grows fat and computer vibrates from electric currents, there is most certainly a defect w/ my unit.
Sorry I can't help you w/ your issue. One thing to note. Once I got back to Toronto, the electrical issues stopped, but suddenly, for about a week, there was a nasty scraping sound coming from behind the keyboard. It was about 5x louder than the whine and sounded like a hockey player sprinting down the ice.

Why won't my charger charge my macbook pro?
I am currently on my 2nd charger and it is the "L" shape charger, It just suddenly won't charge my macbook Pro anymore. Is there something wrong with my mac or is it the charger? The first charger, i can still somewhat use it if I bend it a bit...but it's just too much of a hassle to have to hold the charger to have get my macbook pro charged. Is there something I can do other than to buy another charger?
If possible change the battery anyway. The maximum cycle is 1000 (according to Apple). From my point of view your battery still could have a problem.
Those battery health infos are provided by the chip in the battery. Maybe this chip (controls dis-/charging, counts cycles, measures capacity...) has a damage. This could defeat the charger. Probably... :-)
Or, you play often games which requires more power, than the ratter low power magsafe charger can deliver. This is quite easily possible and when this is the case, the charger and the battery deliver electrical power at the same time. The problem in this case is, that the only 85W from the charger are not enough to charge the battery. The charger can in this case be in the fridge, it still gets really hot... to hot maybe after some houres (when I play games, this happens as well).
Install iStateNano (free widget), it does proviede the health in percentage calculated with the max capacity. If it shows around 50%, you really should change the battery... or sell the mac :-) -
I want to charge my macbook pro in my campervan,what is the best way
when i go travelling i want to charge my macbook pro on the move,not noticed a in car charger,although i have seen a in plane charger,is there any difference between my swift kontiki and a boeing 747.
ianApple's Airline adapter is designed for the apx 15V DC of airlines to NOT charge the computer's battery, rather to slowdown the battery discharge and extend the use of the computer. It also works in vehicles with 12V DV although it's not as strong as the 15V on airplanes.
So that means you need a fully charged battery before you use the Airline Adapter.
To CHARGE your battery your going to have to use the powerbrick adapter for household current on a house hold current outlet, that's in most cases the only thing strong enough to push the electrons back into the battery.
DO NOT USE step up transformer devices that tap off the vehicles 12V up to 110v and then use the Mac's powerbrick to attempt to charge the laptop, it WILL PROBABLY FRY YOUR VEHICLES ELECTRICAL SYSTEM as most vehicles are not designed for that purpose to draw that much current. Most are just strong enough to power the car, the lights, charge the battery and your light your cigarette.
Unless you specially know it can handle it, like big RV's and boats have large appliances powered by the engines 12V system, likely the engine will have to be running all the time to produce that much power to feed the power needs of the converter and the powerbrick to charge the battery.
IF you had a portable generator that could produce enough watts to power a small air conditioner, then you could use the 12v DC to 110v AC converter and the Mac's powerbrick to charge the battery. But most generators of that capability already have built in 110v convertors.
Now there is another option, because the MBP uses DC and the 12V is DC you can use a adpater to convert one to the other, no step up or down needed, so you wouldn't need such a strong source of DC current to use the 110v converter.
Unfortunatly Apple's MagSafe connector is proprietary and patented technology and Apple doesn't want anyone using it. So your stuck either splcing in a MagSafe or using a bootleg charger out of China someplace with no recourse if it fries your Mac.

Charging a MacBook Pro in Europe
I will be taking a trip to Europe next month and need to know if I need to use a power converter to charge my MacBook Pro, or can I just use the plug adapters for the country I'm in. The countries I'm visiting use 220/240V power and someone told me that the computer has a built in converter for this purpose. I don't want to ruin my computer by plugging it in improperly.
"Give a person a fish you feed them once, teach them to fish you feed them for a lifetime!" Any device you want to use overseas there is some little print on the device near the plug input or on the small box inline with the cord. On this box you will see Input power XXX If this only reads 110 (or 115) then it is only designed for 110ish voltage. If it reads 110-240V than it can accept any voltage from 110 to 240 without damaging the product. This applies to any electronic device, hairdryers, shavers, appliances, etc... The 50/60Hz is the speed the electricity flows. Unless it has a motor or a timer, the Hz should not affect things to much.
You will notice there is a output value as well, don't worry about that too much as long as you are using the original cord or acceptable replacement. Your main concern is to make sure any device can accept the 220V.

Hi all
The last couple of days when I wanted to charge my Macbook Pro 13", my magsafe adapter stopped working when my MBP found the remaining charging time.
When I charge my MBP with another adapter, it works fine.
What can I do? Do I have to go back to the store? It is only four months old.sounds like a funky charger, go to the store and try anoher if it messes up have it replaced. They've been having issuses wuth the new charger

If you are using the included Apple charger, you will simply need a plug adapter.

Can I use an adapter that goes up to 250 volts to charge my MacBook Pro?
Am I able to use an adapter that goes up to 250 volts to charge my MacBook Pro? I just want to make sure that way nothing goes wrong.
Use the "adapter" that comes with the Macbook Pro. It is rated for voltages from 100v to 240v.

I forget to charge my MacBook Pro and it turned off because of that. Now it wont automatically connect to saved networks. I have to put in manually to make it work. Even after restating still the same. If I close the lid it looses conection. Sometimes pulling the Battery out will fixes it untill we forget to chage it.

Charging a MacBook Pro (60 MagSafe) with an Air (45w MagSafe) plug.
Can I safely charge a MacBook Pro (60 MagSafe) with a MacBook Air wall charger (45w MagSafe)? I ask because I'm replacing a 2009 MacBook Pro with a new Air and the Pro cord is dead. I'd like to charge the pro with the air charger so I can transfer files.
The short answer is NO. MacBook Airs use the 45 Watt adaptors, 13" MacBook Pros use the 60Watt and the 15 and larger use an 85Watt adaptor.
You can use a larger size to chage one that needs a smaller wattage, but not the other way around. -

Which incar charger for Macbook pro ?
Advise please - I need to charge my Macbook pro 15"(2011)in the car, and having looked around it seems like the choice is;
a Belkin AC Anywhere - 300W DC/AC Power Inverter for £15.87 (Amazon)
or
HyperMac Pure DC Car Charger (Protronica) for £119.95
Seems a no-brainer does anyone know of a reason I shouldn't get the Belkin?
The HyperMac says "it is the ONLY non-Apple solution that supports the MacBook Pro dual voltage (16.5~18.5V) operation." Do I need to worry about this?I have been also looking into getting a car charger and also an external batter and I have to agree with what hypermac say on their website that using a set up transformer and then step down the voltage agian with the normal apple charger is not an option I would liek to consider. in the way of efficieny it is not great you have two transformers radiating heat out so thats a mass of energy down the drain already. and also the comment they made on changing the current form DC to AC then from AC back to DC does not seem very good.
Personally I would suggest buy the airline adapter from apple and then get the Hypermac stuffs. also if you use the Airline apater version rather than the Hypermac box thingy where oyu have to modify the cable it will be an easy thign just plugging in the airline adapter into another adapter so its simple for peopel who dont like messing around with cables I think
I would of cause be interested to hear other peoples opinions on this.
sadly I gotta say I am very dissapoited that apple do not have their own car charger. and also even more a backup battery this is a real downfall I have to say which dissapoints me. Since you cannot just simplly swap the internal battery in the mac. -

No.
Power Adapter/ cord wattage
“Power adapters for Intel-based Apple notebooks are available in 45W, 60W, and 85W varieties. Although you should always use the proper wattage adapter for your Apple notebook, you can use an adapter of a higher wattage without issue.”

Can I use my thunderbolt display without charging my macbook pro?
First off- Here's what I have-
2012 13 inch Macbook Pro
2.5 GHz Intel core i5
8GB RAM
Stock 500GB 5400rpm HDD
Mountain Lion OSX
Anyone know how I can use my thunderbolt without charging my Macbook Pro?
Also, my Thunderbolt jack, port, and my overall computer get really hot when I'm using my display. Anyone else have this issue?
Thanks!Ohhh I see it now.... The thing is I only have 13 cycles on my battery, but the max is only 92% percent charge... I thought that would be the charger charging my MBP and using the battery at the same time.... Another thing, would you happen to know why I have a max of 92% charge and only 13 cycles? (Two different apps are telling me the same thing...)
