OS X :: Need To Unplug Magsafe Adapter When MacBook In Sleep Mode?
Jul 28, 2009
This may seem like a really simple question to someone who is familiar with Macs, but I am brand new. When I hibernated my old Vista laptop, I always unplugged the power adapter (it go too hot if I left it plugged in overnight). With the Macbook (Macbook Pro 13, mid-2009), should you leave the Magsafe Adapter plugged in, or is it OK to put the Macbook into sleep mode overnight, and leave the charger plugged in? I don't want to deplete the battery (that flashing LED makes me wonder what kind of battery draw there is in sleep) by putting my laptop into sleep mode for eight or so hours, and not have the charger plugged in.

I've got the new i5 mbp which has the right angle magsafe plug. Can I use any older magsafe adapter on the machine?I need 2 more (one for work and one for home), i'm too lazy to take it out of the bag, or I always forget to put it back when I need it.

I have tried SMC and PRAM resets, and the issue has not been resolved. My magsafe is lit up with a bright green led. Battery status is "Not Charging." When I unplug the magsafe, the system immediately shuts down. Battery is brand new with only 2 cycles. While I can use the laptop with power connected, this is an issue that needs to be corrected asap, as I use this computer for performances consistently and if the power cord gets removed, I'm not in a good place.

1) If my MacBook Pro is fully changed and I plan to put it to sleep mode, do I still need to let AC adapter plug in?2) Let the computer to sleep or turn off is better when I don't use it?3) What's the normal "Fully Changed Capacity"? Because I saw it changed from time to time when I check in "Apple system profiler"?

I have a Macbook that is nearly three years old, and I'm on my second power cord. The first time I had trouble, the casing had melted off right next to the MagSafe part that plugs into the computer. I got another, and now it seems it won't charge at all. There is no apparent physical damage. At first, I could do a little jiggery pokery and if I got it in just the right place, it would charge. It seems that now even that is gone. I'm wondering if: 1. There is some obvious fix that I am missing, or 2. Where I can get an affordable replacement. I realised this makes it sound as if my current cord is brand new, that is not the case. It is about a year old.

It especially happens when I am watching videos. I bought a cooling pad to help with how hot the macbook gets, but the magsafe adapter is burning hot to the touch. It's making me nervous. Is this normal? Can it be replaced? My macbook was only purchased

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).

My Magsafe adapter for my Macbook Pro all of a sudden stopped working. It's no longer charging my MBP. I've noticed usually when charging my MBP if i listen to the adapter it will give the sound like very small motor or gears are running. Now it just sounds like a long beeping sound. I was wondering if this is some known defect, because I made an appointment with the Genius bar for tomorrow and from what I have heard Apple is known for replacing defected parts even if they are out of warranty.

I had my original MBP charger replaced a while ago because the magsafe adapter light was not working. (but it charged the computer fine, weirdly enough) Then, about a month ago, the light on that one went out too. The apple store replaced it with one of the new MBA chargers style. That one worked for about a day, and now intermittently goes off. What is wrong here?

I was very surprised and scared at the same time when I see my magsafe power cable frayed badly at one of the connections to the magsafe unit. I was very lucky to notice before sleeping, or else I would have ended up in a fire at my home. I was planning keep MBP for charging and go to sleep when I noticed this. But luckily I smelled burning and noticed that the frayed had part started blackening due to burning. I immediately disconnected it. See the pic below.
I use the charger as it is expected. Remove it from the solid plug and not cable. Actually I use all apple products with care and respect and I love them. But this incident broke my heart. I have so many presentations to give this week, how I am going to survive without my laptop is a big question. I just saw many people have had such problems, and I am hoping Apple customer care helps me out tomorrow morning. Only 14 minutes left on charging before my MBP dies. Apple help.
Strange thing is my power charger was just replaced 6 months ago for a different problem(it just stopped charging without any reason or visible damage, no fall nothing). And now after 6 months the new charger gave up with a frayed cable. I work as a Teaching Assistant and have so many presentations every week, this is a unnecessary trouble for me.

The line just get ripped or teared even when carefully wrapped around the plastic corners. Apple won't replace it for it is considered "physical" issue. Yeah, you got it right, Apple. It is a physical design flaw! No wonder so many websites selling third-party Adapters. I know Apple's products are nice and beautiful, but they should not be encased in glass container to be admired! They are supposed to be used in the REAL WORLD! Come on, Apple. Fix your badly designed products, already!

I recently bought a new charger called the 60W MagSafe Power Adapter, for some reason for the first time when I plug it into my Leopard Macbook, it works. But when I take it out and plug it back in, it doesn't seem to charge. I would have to remove my battery and place it in again for the charger to charge my macbook. I don't think the charger is the problem because it charges on my macbook Tiger fine.

Firstly i have a MacBook 10.4.11 that is somewhere between 2 and 3 years old. I have had no problems with the Mac up until yesterday. Yesterday i was charging my Mac and everything was fine but i noticed that the MagSafe Adapter was lit up Green, even when unplugged from my Mac. I shrugged it off until this morning when i realised that when i unplug my adapter the Mac just turns off and won't turn back on until i plug the adapter back in. I have seen different threads about it being a battery problem or a charger problem but i am not sure where to start as most of the threads say that their Battery Icon on the Mac screen has a black "X" through it. Mine just has the Forks in the battery icon and where it would have a Time or % of what is left in the Battery, it just has a (Calculating...) and when i click to see how much it has charged, it says 0%
I also downloaded Coconut Battery and here is what it says:
Current Battery Charge: 0 mAh
Maximum Battery Charge : 5093 mAh
0%
Current Battery Capacity: 5093 mAh
Original Battery Capacity: 5020 mAg
100%

My battery doesn't last much more than a few hours during continuous web streaming, 2.) That my battery stopped charging to 100% two days ago..and 3.) Last night when I went to unplug it, the power adapter was very hot to the touch. Out of curiosity, I went and used my laser thermometer to get a temp reading of 120-128 degrees F.

As of last night, my MBP started acting very strangely. After entering my username and password, it would enter the desktop for a short period of time and then kick back into sleep mode; the screen would turn back to black. Sometimes it will let me stay on the desktop for a long time and other times it will hardly let me stay on the desktop. I called apple support and they had me start the computer in safe mode; even then it occasionally kicks me out.
The tech guy said that it was a "strange software issue" and not a hardware issue. I thought it was a hard drive issue; my hard drive makes an odd sound when it unlocks (a grinding sound), but it has been doing that for quite some time with no issues. I tried to reset the SMC and it didn't do anything.
How should I remedy this problem? Is this a hard drive issue? Hard drive failure? Has the grinding sound finally caught up with me? I am running OS X; not leopard or snow leopard. I know I need to upgrade, but this shouldn't be happening.

I have both a MacBook (personal) and MacBook Pro (work; provided by NASA). The MacBook has a 60W Magsafe Power Adapter; the MacBook Pro has a 75W power adapter. I am going on international travel for several weeks, do I need to bring both adapters with me? Would there be any problems caused by using a higher-power (75W) power adapter to charge a MacBook or vice versa?

I wonder if somebody has a similar problem. MacBook pro 2008 (15", 2.2 GHz, 2 GB RAM) has the Magsafe adapter light off when fully charged. When disconnected-reconnected, it starts glowing green again.
History: about 6 months ago, the screen wiring and video card were replaced by Apple. The battery was replaced a long time ago. Symptoms after card replacement (not necessarily related to it) included spontaneous wake from sleep when the lid was closed, although the "wake from sleep at Ethernet activity" was disabled. In the Apple store they reset the power management unit and the unwanted wake up stopped. The computer is always plugged into the wall outlet when at home but travels often during the day and is on battery power then.
Two other laptops (2007 and 2009) always have the adapter green light on when the battery is fully charged. The "abnormal" one now has a replacement adapter plugged in and for several days the light was on when charged. Today it turned off again. Apple does not list that option and only vaguely states that when fully charged, the adapter light is green. Anything to do with the power port contacts? If yes, how can one diagnose or repair it? Will Apple hardware test do it? Or is this within normal behavior? Also, I am not sure whether this is serious or not since the battery charges...
I did not find any answers on the web, so I am posting it here.

I saw over the last couple days some type of rubber/plastic (maybe even neoprene?) case/holder that you put the MBP magsafe adapter in and then you could wind the cord around it. I think it was orange in color. Does anyone know what this item is called? Added after about 20 minutes of searching the web: [URL]
