45W MagSafe Power Adapter for Air
What is the best way to tell the two power adapters apart 45W Air adapter and the 85W Macbook Pro adapter?
What happens if you use the 85W adapter on the air?
It's Ok to use an adapter of a higher wattage then the one that came it.

Is this the right power adapter for an 11" MBA?
My wife has an 11" MBA with model number A1370. The battery is dead so I can't check the exact model identifier. The thin cable on the power adapter has worn out where it enters the brick (which is incredible since she never ever wraps the cable around the brick) so she needs a new adapter.
This Dutch Apple Store page has three that look similar to hers, which has the L-shaped magsafe. Am I right in believing that the 45W version will fit all A1370 models?
Many TIA

Is a 60watt MagSafe Power Adapter compatabile for a MacAir?
I have a 45watt Mag Safe Power Adapter for my MacAir. I also have a 60 watt Mag Safe Adapter, and says on box, only for MacBook/Pro. Can I use this for my MacAir??
To quote from below linked article from Apple:
"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."

I need help identifying which Magsafe Power Adapter I need for my Macbook Pro Model A1398, EMC 2673?
Provided the computer-end fits, you are free to use one with a HIGHER Wattage rating. No damage whatsoever will be done to any component, but it will likely run cooler (but may be slightly heavier).
If you use one with too LOW a Wattage rating, you will not be able to charge and run at the same time, and your computer's top speed (for its most intensive computations) will be limited. -
45W or 65W power adapter for T440s
Which is the correct power adapter for the T440s....45W or 65W adapter that Lenovo is selling under the accessories section? The websites pulls up both adapters for the T440s. The 45W adapter output is 20 volts, 2.25 amps and the 65W adapter is 20 volts and 3.25 amps. Is one adapter more recommended over the other? Are their pros or cons to either? Does one charge faster but reduces the battery life?
@sjahanmi,
Parts list for T440s -> http://download.lenovo.com/parts/ThinkPad/t440s_fru_list_20130724.pdf
I will recommend calling the call center to get the recommended AC for the laptop.
Which AC did your laptop came with btw?
For mine I had the 65W for my T420 however one of my colleagues had the 90W one, its also usable however it seems like their laptops charge faster than compared to mine. I am not sure if its a placebo effect or it does charge faster.
I think the best way for you is to contact the call center and provide them with the machine type and they will recommend you accordingly.

Is this power supply (A1185 10.8 V, 55Wh) compatible with New White 60W 16.5V 3.65A Laptop AC Adapter Supply Magsafe Power Charger For Apple Macbook pro A1184 A1185
All of the A1181 polycarbonate MacBooks use the A1184 60W MagSafe power supply/charger and the A1185 battery. These are the Apple part numbers. Other manufacturers make equivalent replacement products, but the quality may not be acceptable.

Can I use my old magsafe power adapter?
I just bought MacBook Air, because my MacBook Pro died... I need two magsafe power adapters (for work and home) and I was wondering whether I could use my old ones from my MacBook Pro? The watt is way off, though (85 W versus 45W). Any experiences?
Thank you,
AndreaYes, you can use the adapter of a higher wattage.

Which MagSafe Power Adapter?
I have a MacBook Pro 5.4, 15" screen, purchased in 2009 I think. It came w. a 60W MagSafe Power Adapter. I want to purchase a 2nd power adapter for my alternate work site. I see that an 85W MagSafe is being specified for the 15" PowerBook Pro. Is the 60W one I have all right to use, and should I buy the second one as an 85W?
What about using the 85W Mag Safe 2 Power Adapter (used on MacBook Pro) for my MacBook Air which comes with a 45W Mag Safe 2 Power Adapter? Is there a problem with that?

I have been having a problem for a little while now, and I have decided to overlook it for the most part. However, it is really starting to get on my nerves. The issue I don't believe is with the MacBook Pro itself, however with the MagSafe power adapter. The adapter itself is in great condition, it is brand new, but when I attach it to the computer, the computer reads that it is there, as it shows it is charging or is charged as shown by the battery indicator in the top right of the OS X toolbar. However, the amber and/ or green light doesn't come on, right away - the first time - most of the time, on the adapter head itself. I usually have to unplug it and plug it back in multiple times before I get a light to come on. I have tried to clean the adapter itself, and the MagSafe port on the computer, but that seems to only help for a short amount of time, and it doesn't look real dirty, or like any pins are stuck on the adapter. I have also tried other outlets, but that doesn't seem to help, so I don't think I am getting dirty power.
Unfortunately, it *could* be the computer. And it could be the adapter. Aside from trying Resetting the System Management Controller there's not much you can do except taking it in for testing.

Question about MagSafe Power Adapter
I just got a new magsafe power adapter and wanted to know if leaving it connected to the electricity for too long damage it?
Last question, my battery is dead, should I take it off andrun on the adapter, or just leave the battery on?
A friend of mine told me tht "dead batteries" ruin power adapter?
Thanks allI'm afraid you should buy a new battery, Frank.
Running on the power adaptor alone will slow down your MBP. - see http://support.apple.com/kb/HT2332
Running with a seriously defective battery installed, though, may not only place a heavy load on your adaptor but may result in the battery deforming (causing other damage) or worse.
Leaving your adaptor plugged into the power when not being used probably won't hurt it, but it will use more electricity than a fluoro lightbulb.

85W or 60W MagSafe power adapter?
I'm buying an extra power adapter for my MacBook to use at the office.
Both the 85 watt MacBook Pro and 60 watt MacBook power adapters have MagSafe on them. They are both the same price. Should I consider the 85 watt adapter for my black MacBook? I was thinking that I could get the larger wattage version so that I'm not fully taxing the unit, allowing it to run cooler and potentially prolonging the life.
I know this is kind of an off-the-wall question, but I'm curious about these things. Any thoughts are welcome.It's easy these are very good instructions on How to Upgrade Your MacBook's Hard Drive.
Here is the Apple Apples DIY hard drive replacement instructions.
The only step they left out is the need for a number 8 *Torx Driver* to swap a shield from the old drive to the new. Apples DIY Warranty Info

Hello,
My white McBook (2008 or 2009) recently stopped turning on. When I hook up the Magsafe power adapter, the light shows green, but the computer will not turn on, or make a sound. I've tried the re-boot option, but nothing works. I first thought I needed a new battery because the lights at the back are all off, but shouldn't the computer turn on once the power adapter is hooked up and the light on the Magsafe adapter shows green? I'm a computer doofus, so please be kind. Please advise! Thanks in advance.
SSTake it in for service.

Can you plug in your 60w magsafe power adapter to peru without harming it?
Yes you will need a plug adapter, the power supply is rated for 100v-240v. Apple has a travel kit full of adapters you could also check the web for a particular one for your needs.
