MacBook Pro :: Do Magsafe Adapters Only Initiate Charging After Laptop Closed
Apr 18, 2012
I purchased a replacement magsafe 85w adapter for my MacBook Pro and was wondering if the new cable requires you to have your laptop closed to initiate the charge process on your computer.I notice that if I attach it with my laptop powered on and my computer open it will not initiate a charge (light up on the cable or show the charge icon on screen). If I power down my laptop and close the lid, disconnect and reconnect the magsafe cable the light on the cable will light up and initiate the charge. I tried this also on sleep mode with the laptop closed and the light on the cable started up without disconnecting. I was able to boot up my computer and continue working and the charge continued but I had to initiate it first with the lid closed either in an off or sleep mode. Just wondering if this is the new norm as I just moved from the old "T" style magsafe to the new "L" style magsafe.

These are the specs of the MacBook Pro that I have. Long story short a dog got near the AC adapter cord and had its fun. I need to purchase a new AC adapter and went to [URL] to look for one. I noticed there are many different 60W adapters listed for specific MacBooks. I was curious if there was a big difference? Right now I've had to use my ac adapter from my early 2006 MacBook and I haven't noticed any problems. My main question is if it would be OK to buy an ac adapter on Amazon such as: this.

My MagSafe adapters does not stay green. If I unplug it from the wall and plug it back in it will light up. When I open up my laptop the light goes out. It is still plugged in and the computer still works.

I'm having some major problems with my Macbook pro. First, since I first got it my macbook has eaten through 4 magsafe adapters, no matter how nice I try to treat them. My husband, who got his at the same time, is still on his first. My latest one just bit the dirt today, and I'm using my husbands adapter to get online long enough to write this. Even with his adapter, the battery is no longer even charging. The icon shows it as charging, but it says it will take 10 hours and it has not increased in power since I plugged it in. The computer is currently at 0% charged. I'm afraid to just buy another adapter for fear it will break again, and I don't want to ruin my husbands adapter either. My computer is no longer under warranty and I'm afraid to bring it in for diagnosis for fear of the cost, depending on the problem.

My friend has a late uMB and his magsafe port is very very lose. Coincidentally, his battery stopped charging around 10 days after. His computer always runs on AC power and it says the battery isnt charging but it gains around 4% every hour. He thinks its because the lose port, but I think something else is wrong. Anyone have any ideas?

Having weird problems with my MacBook Pro 13 (MacBookPro5,5). I bought this needing repair and replaced the LCD, the LCD Glass, the Camera/mic cable, and bought a used battery because the old one showed "Service Now". Just when I thought putting all this work in would get me going, I ran into two different problems that are driving me crazy. The battery will not charge with any magsafe attached (I have quite a few). The only way I can get it to finally charge is to remove the bottom cover, unplug the battery, and use a new, l-shape 85W Power supply to get it to charge again, It charges ONLY until I remove it. Once I remove the power suppy...even for a second, I will not light up again and it will go on battery power until it disappates (then I start all over ). I've tried every reset in the book, so it has nothing to do with the PMR or SMC (or however they are named). Also, before anyone asks...the old "Service Now" battery behaves exactly the same way .The isight camera STILL does not work, even with the new cable. Furthermore, I had another cover for the same unit with a camera in it and its own cable and tried to use the camera with that setup, and it still did not work. My guess is there is either an issue with logic board or the cable connector on the logic board.
The Apple Hardware test passes perfectly every time I run it (quick and extended). Disk is fine...checked it with drive genius and disk drill. I am open to suggestions if anyone has them. I'm guessing this is out of warantee, nor was I the original owner. Anyone have any ideas? Open to anything at this point.

My magsafe 2 is plugged in but the light's not on. My battery status shows it plugged in, but says "battery is not charging."
I've reset the SMC several times and have been able to get it to work again, sometimes after going through the process several times. Sometimes the yellow light stays on even after I unplug the magsafe.

just moments ago i plugged in my mbp and literally 1 minute or so later i hear a static fuzz sound (hard to describe) but if i had to give a similar sound it was exactly like the sound your radio alarm clock makes sometimes when your cell phone is nearby receiving an incoming call or text w/e, your alarm clock sometimes makes that sudden static fuzz sound.
well my mbp made that sound, wasn't as distorted as an radio alarm clock would make, but it sounded more precise. the sound came out of the left speaker for a second or so (no music or movie or any program with sound effects were active at this moment) i believe right where the magsafe is hooked into. and i was like "what the heck was that?? and was it from my mbp??" so i looked at the magsafe and sure enough the orange charging light was out as if it was unplugged (but it was still plugged IN) so i unhooked it then rehooked it and now it charged like normal again, still hasn't done it again while i started this thread.
any thoughts?? additional info i have to add is, i was swapping out the extension pieces from the smaller cord adapter, to the full 8 foot or so cord one. but when i switched out the small single piece i tugged in the opposite direction, i pulled up against the metal circle joint, instead of sliding left to unhooked the metal circle thing (w/e u call it). i felt the piece and its in full contact, i didn't loosen it or anything. could this be the random cause?
lastly, that static noise i heard that ended up causing the magsafe to stop charging. could that static noise damage my speakers?
additional info i also had my cell phone like 8 inches away from the magsafe. could the cell phone have the same static frequency or w/e that can interfere with the magnet/charging cycle?? i didn't receive any calls or texts when it happened. so i dunno if cell phones have frequencies constantly that could possibly cause my issue without having the receive incoming calls or texts etc.

Someone tripped over the wire of the MagSafe charger, and it came away from the macbook, but split the L-Shaped part in half, and left the magnetic end stuck inside the charging port, and the other part exposing the gold pins. Is there any way I can remove the magnetic part myself? Or should Apple be able to do it for me?

I was playing Starcraft on my macbook (old 2008 white macbook) as I have windows 7 ultimate installed on this as well and all of a sudden the macbook died. I went to get the charger to connect it back to the macbook so I can play again. After a while I decided to just use the macbook on the battery alone but when I pulled the magsafe out the whole thing shut off and it wouldn't turn back on. The battery indicator shows 3 out of 5 left on it so I know the battery still works..i think... then I turned on the macbook with the power plug connected and it says "Not charging"...Is there something wrong with the magsafe or the battery? I dont think its the magsafe since it is working when I connect it and the macbook turns on...However it just keeps staying lit GREEN the whole time. It usually turns orange too mean it is charging

I have a macbook pro and I want to be able to hook it up to my TV and close the laptop lid. Every time I close the lid, the TV goes black no matter what settings I change! I'm not sure if the laptop is going to sleep, or just disconnecting the TV as a display.
I've tried something called Caffeine, but it didn't do a thing.

I dropped my MacBook Pro only about 12 inches and the corner of the shell where the Magsafe connector is located was bent slightly inward. When connected to the AC power there is enough power going through to run the laptop. However, the battery is not charging and now has no green lights when I push the button on the battery. I checked and the battery has been through 129 cycles so should still be good. I'm assuming that means something was damaged with the Magsafe connection when the corner was dented. Does anyone have any advice? How much it would cost to repair the Magsafe connector? My MacBook Pro was purchased in 2007 and I have no other issues with it. Would it be worth repairing or should I get a new one?

i have been a 13" macbook user for over a year and love every moment of it.
I work on large spreadsheets daily with the laptop open and another 19" monitor. I am considering adding another monitor and keeping the laptop closed.
Is such setup possible? Have 2 screens on my desk, plugging the laptop to them, keeping it closed and working solely of the 2 external monitors?

I have a macbook pro 13" and I'm running on Snow Leopard Mac OS X 10.6.6. What happened is that I close the laptop while it was turned on. After a while I opened it and the screen wouldn't turn on. Other thing I noticed was that the sleep light was also turned off, instead of blinking.

I just bought a new MacBook Pro with a solid state (flash memory) disk. The battery life is good while I'm using it, but if I leave it with the cover off for a few days (asleep, I assume), it'll be mostly discharged when I open it up. I assume this isn't normal - it shouldn't be losing that much charge when closed and hybernating. I don't have "wake for ethernet access" checked, if that makes a difference. What's going on - why won't it hybernate?

Just got my first Mac last night, MBA 2.13/128SSD. So far it's been a questionable purchase, the two things I need it to do I cannot do with Mac OS X and Safari. Need to use a digital ID for law school which won't install in safari and can't watch Real Player lectures as I cannot enter log in info. Installed Vista Ultimate using Parallels (have not tried VM Fusion) and it works but the videos lag.
I partition 10G in Boot Camp and tried to install (1st) Vista Ultimate, (2nd) XP, (3rd) XP SP2, (4th) Windows 7b, none of them worked. After I set the partition and select to install, the Mac reboots and then the gray Apple screen appears with an Apple Logo and Folder. I've searched for hours on Google and I can't find a single article that answers my question as to why this is happening and how to avoid. I realize I cannot use XP, but Vista Ultimate and XP SP2 and possibly W7 should have done something..

My Macbook pro is not charging. If I move the cord (specially at the Macbook charging port) it charges. But again if the cord is slightly disturbed then it doesn't charge. The problem got worse as my Mac randomly shuts down (especially when I remove the mag at the Macbook charging port). I dono what to do. Apple care (Genius) is far from my place.There is no visible physical damage on my mag charger. Could anyone suggest what I should do? I checked the battery status in system profiler and it says NORMAL. The details are as follows:

I have an 13" MBP that I ordered new in April, 2012. It is running Lion. I have an external monitor that is capable of 1440x900 resolution. I have an external keyboard and trackpad hooked up, and I like to close my MBP up and stick it in a BookArc. I want to be able to have the internal display disabled and to have the MBP only allow me to put windows on the external display, so long as the lid is closed. I also want to be sure that I am taking advantage of the resolutions available on my external monitor, which are higher than those supported by the internal display (specifically 1440x900).
This doesn't seem to work because I either have to allow the MBP to continue to draw my desktop across both screens (internal and external), OR use the "mirror displays" mode, which restricts my resolution of my external monitor. This means I either forgoe the additional resolution benefits of my external monitor, or I end up with windows that fall off-the-cliff, so to speak, because they are drawn in the portion of the desktop that would be shown on my internal display (which is closed).
I've read the community support pages on using the MBP with an external monitor, most relevantly, this page. It simply recommends using the "mirror displays" option. However, this option, as I mentioned above, doesn't allow me to make use of the additional resolution, and my external display looks bad. how to keep the 13" MBP in closed clamshell position, with the internal display disabled, and use my external monitor at resolutions higher than those allowed by the 13" MBP but which are available to my external monitor when not in "mirror displays" mode?

My mac has been acting very weird since i installed leopard and ilife 3 weeks ago.
1. Running slow (taking a long time to open programs)
2. Sometimes when i click on my external drive icon its empty.
3. Grey screeen comes on telling me to restart.
4. Starts making a loud fan noise when i leave it on for a over 24hrs.
Then this morning i turned it on to copy a file to my jumpdrive and i click on the external (seagate 250) drive and again its no icons or anything inside.
So i go to spotlight to see if i can type in the name of the file and no file is found. But i did notice that it said "indexing"
So i waited for 3 minutes. Then i did what i always do when it starts bugging out. "restart"
After the restart it ask me would i like to initiate the disk drive or something to that affect.
Please dont tell me my external is fried. I have tons and tons of work on it.
