Use macbook pro on power adapter or on battery?

Is it recommended to use my macbook pro with the power adapter plugged in or using the battery? how does it affect the battery?

http://www.apple.com/batteries/notebooks.html. i keep it plugged in most of the time. i use it on battery only when i need to, or at least 1-2 times a month.

Macbook pro 15' power adapter not working

When I was using macbook pro 15' early 2008 this morning, the power adapter suddenly did not work. The led light on the power adapter blanked and the status bar showed that I was using the battery. I am sure about the power adapter is fine cause I try it on another macbook pro and it works well. I have tried to take off the battery and the power adapter for 30 secs and then press the power button. But it does nothing good. I have tried to press the option + command + "R" + "P" and power button to reset PRAM. But the problem is still there. Now I have run out my battery what should I do ?

It sounds like the power board inside the MacBook Pro has failed, best get it to an authorised repair centre.

Late 2008 Macbook Pro: Which power adapter?

Hello all. I have a Late 2008 Macbook Pro 15", MacPro5,1. A few months back my dog ate the power adapter (unplugged, thankfully.) I thought I did the proper amount of research to order the correct adapter from a third party on Amazon, because I'm pretty darn broke and need to save every penny I can. When I got the adapter, the connector was different from the one that came with my Macbook Pro. It was 85W, all the numbers matched up, but the style was different. But, the plug worked enough to let me get the work done that I needed, so it didn't concern me too much.
That is, until this cord just stopped working. That's what I get for getting a third party cable from China off Amazon.
So now, I'm trying to research again to make sure I'm getting the right cable, and I want one that's made by Apple, and is exactly like the one that came in the box when I bought my Macbook Pro new. I went to MacSales.com and checked their compatibility pages, and ran into some issues. What is showing as compatible with my Mac is the 85W Magsafe MC556LL/A, but this is shown with the incorrect connector (like the one I got off Amazon.)
When I looked at the other adapters that were available, I found the MagSafe 2 85W MD506LL/A, which has a connector that looks like the original, but it only shows as compatible with 2012+ Retina Display Macbook Pros.
So, do I have to buy the MagSafe that is not like the original that came with my Macbook Pro, or can I get the MagSafe 2 that does match what I got out of the box?
Reference pages from MacSales.com:

Thanks! I didn't realize there was a revision, but that makes sense. I guess I don't understand they would change it, then use the original design for the later Retina Display models. Oh well, as long as it works!
On a similar note, is OWC the best option for a cheap Apple-brand adapter? They're selling them for $47, when the cheapest I can find anywhere else is like $75. They seem pretty reputable with all the options and Apple-specific stuff they offer, I just didn't want to make the same mistake again and would like other options if they are available.
Thanks again!

Macbook Pro Magsafe Power Adapter

Hi,
I recently have bought a new Macbook Pro 13". Will using its charger (model no. A1344) to charge my white Macbook (late-2006 model) damage it? The white Macbook's charger is no longer functioning and I didn't buy a new one… Do you recommend buying a new charger for white Macbook? I just don't wanna end up with a new laptop and a damaged charger..
Thanks...

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 Pro 17" power adapter lights orange when NOT plugged into laptop.

My MacBook Pro power adapter lights up orange even though it is not plugged into a device. When I do plug it into my laptop it remains the same and does not charge. Due to this my laptop is now dead. What does this orange light mean?

You should take both your MBP(Macbook Pro) and your power adapter to an Apple Genius bar or an AASP(Authorized Apple Service Provider) for a free evaluation. This is a strange occurance, and it seems that it may be a hardware malfunction.
Make an appointment so you don't have to wait too long.

Macbook pro magsafe power adapter - cord melted

Has anyone had the cord on their power adapter burn or melt through? I've had my Macbook Pro for 3+ years and taken great care of it. I experienced the battery bulge issues and has two batteries replaced under AppleCare. I came home yesterday to find this:

Any ideas?
I realize I'm outside of my AppleCare now but I still find this alarming.
Thanks.

I would take MBP & Magsafe to your local Apple Store or AASP. Otherwise, see the following KB Articles;

Macbook Pro 13" power adapter

I bought my Macbook pro 13" from someone around Christmastime last year (who bought it only a few months prior) and it works great. However, my power adapter is dying and my AppleCare and warranty are up. It's very finicky and only works about 10% of the time anymore. It's the newer model of adapters that are round and thinner than the old flat rectagular adapters. Could I buy the older model for my Macbook and it'd still work? Or do I have to buy another newer model adapter?
Thanks!

I recommend getting the one designed for the unit to ensure long-time reliability.

New Macbook Pro Penryn Power Adapter Whine/Buzz

Hi all,
While I was using my new 15.4" 2.4Ghz MBP Penryn last night I heard a high pitched whine coming from the area. I tracked it down to the power adapter that was plugged into the wall. I tried it on several different outlets in my house and heard the same amount of whine.
Interestingly, that if I have the adapter plugged into the wall, it doesnt have to be plugged in to the MBP to hear the whine. This is reassuring as it doesnt appear to be anything from the MBP causing this.
Has anyone else heard this type of whine from a apple power adapter?
Jeff

I do not know if we are talking about the same thing, but I wanted to at least add my situation to the thread to help others in narrowing down the issue. I am experiencing a strange buzzing issue right out of the gate with my new 2.5Ghz MBP. It is on the right side and is a constant low pitched buzzing that sounds either like a fan or hard drive. The best analogy to a sound would have to be the noise a loose wire, on a home audio system for example, sounds when not properly connected. This noise is pretty annoying in a quite environment and not something I could say sounds appropriate. I have never heard such a consistent noise in the in the nine years I have been using apple notebooks.
I called apple care today and they said it is increased fan speed due to the smaller chips and higher processor speed, which is total bs considering I just had a 2.4Ghz MBP. I am slightly irked by the fact that customer support would come up with pretty pathetic explanation such as that and obviously bothered by this noise even more.

2ghz intel core duo macbook pro 15 power adapter

What is the model number for the correct power adapter for this laptop?
Which models will work? There are 60w and 85w.

The 85 W model is for 15" MBPs. Either of the two listed on Apple's Online Store will work.

Macbook Pro Magsafe Power Adapter is very hot. I never noticed this before. Is this normal?

Has anyone experienced this? Is it normal to have this adapter soooo hot?!

Warm to touch is normal.

Use MacBook Pro power cord with iPad?

Hi all - if I remove the two prong AC plug from the iPad's power brick, the exposed connector looks like it will accept the extension cord that was included with my MacBook Pro's power brick. Is there any reason I couldn't use the Mac's cord with the iPad's power brick this way? I assume not but just want to be safe.

Hi,
Is there any reason I couldn't use the Mac's cord with the iPad's power brick this way? I assume not but just want to be safe.
Not is correct.
Only use the cables and the 10W USB Power Adapter that came with your iPad. Otherwise you could damage the hardware and void your iPad warranty.
If you are running v10.4.8 on your Mac as your profile suggests, be aware the minimum system requirements for the iPad for Mac is v10.5.8 as noted here.

Connecting kurzweil sp88 to GB I want to connect my Kurzweil sp88 to GB. The Kurzweil has a baffling array of buttons and possible MIDI channels. It also has the old style MIDI plug ins. I've got the MIDI out connected to my MacBook Pro via USB adapter.

I have my Kurzweil connected to my MacBook Pro via an adapter (old style MIDI from Kurzweil to USB adapter connecting to Mac). The Kurzweil has a baffling array of buttons and possible MIDI channels. Can anyone please tell me which of the channels I should use? Also, should I leave the MIDI In cable out of the Kurzweil? Thanks for as detailed an answer as possible. If you like you can respond directly to me at [email protected]

First of all I do not own this keyboard. But a quick look at the manual (found on the internet) says that when first powered up the SP88 is in Internal Sounds mode. Meaning you hear the sounds selected when playing the keyboard. It also stated that the default Midi Transmit Channel is Midi Channel #1.
Looks like you would need to go to the SP88 Keyboard's MIDI SETUP and simply select LOCAL OFF. Now the keyboard should be ready to transmit Midi Out only and no internal sounds should be heard.
Next you may or may not need to do this but you might need to go into the Utilities Folder found in your Applications Folder on your Mac and double click AUDIO MIDI SETUP the keyboard Icon. Figure #1 below.
Next you need to make a physical connection from the Midi Out of the SP88 to the Midi In on your Midi Interface. Figure #3 below. You may need to Click on Add Device first. Figure #2 below.
In the examples shown below I have a Yamaha Electronic Drum Kit that is Midi Out only... not USB out. I had to plug a Midi cable from the Midi Out Port on the back of my Drum Module to the Midi In Port on the back of my Motu 828 Audio Inferface which is connected to my Mac. Next I created the Audio Interface and Drum Module "Devices" as mentioned above.
I then double clicked on the Drum Module and made my Midi Out Selections. Figure #4 Below. And once it was setup and the icons closed I used my mouse to draw a virtual cable connection from the Drum Module Out to the Audio Interface In. Figure #3 below. This is how I got my Midi Devices to talk to one another.
Once you have made your setup as I have outlined create a MIDI Instrument Track in Garageband, select an instrument for example a Piano then Record Enable that track in Garageband and see if you now hear what you are playing. In this example the SP88 is a Midi Controller only and you will only hear sounds selected in Garageband which is what you want.
Keep in midi your setup may be different than mine. You can keep your SP88 Keyboard on the default Midi Channel #1. That would be a good place to start. Garageband receives Midi on all channels.

What is the best way to use a macbook pro? Plugged in or on battery?

Is it better for the computer if you use it while it is plugged in or to use it on battery until it needs recharged and then recharge it all the way before using it again? Which way is it better for the computer in the long run?

It doesn't really make any difference unless you don't really need to use it on battery power. Use the battery when you can - when you are mobile. Otherwise, use the charger.

Okay to use MacBook Pro without battery?

Now I fully understand that it is not such a great idea but I wanted to get some opinions: It's my third NuPower battery. All of them have lasted less than a year and failed pretty bad. This one started bulging quite bad and then I couldn't use the trackpad click button anymore (because it was putting pressure on the trackpad / button.) I took it out and the battery started expanding even outside the laptop! I don't consider myself a rough user. I do occasionally reccaliberate the battery per Apple, make sure I raise the laptop off the table etc. to let air pass under. Currently I am overseas and many Apple resellers do not carry the battery in stock. So I have ordered the battery from Amazon. In the mean time, I am using the MacBook Pro directly hooked up to the 240V outlet with the Apple supplied adapter.
I have heard a few people do this in emergencies. But what say you?! Unlike the US 120V, it's 240 Volts here in India! Somehow I felt better with the battery being there to absorb the jolts! but I have had no issues so far - two days. The Mac wakes up, runs, sleeps fine without a hiccup! I am taking extra care not to trip the extra-easy MagSafe adapter
Has anyone done this? Any direct adverse effects caused by running it straight from the outlet without the battery?
