Dim green light on magsafe adapter when NOT connected to MBP

Yup just like that!

 

This is my second power supply for my MBP.
I have the 13" mid 2009 model.

I plug the adapter in and i get a faint green light, battery is SLOWLY charging, shows charging indicator.
BUT... says not charging, and service battery when i click the battery icon.

My magsafe isn't yellow.. just dim green.

 

NOW.. when i disconnect the magsafe from the MBP, the dim green light is still there! still dim and green! I have tried other outlets and still dim and green... ALSO i did notice, in my system profiler, under power, there is no information for my AC power. its all zeros...

 

I have tried resetting the SMC, but there is no for real telling if it worked or not.

I have cleaned my connectors.
tried other outlets.

 

ANY IDEAs??? NOW remember the dim green light stays on when the magsafe is NOT connected to the MBP1

 

Thanks!

My MagSafe Charger / Power Supply is not working

I am using mid 2009 13" MacBook Pro with 85W MagSafe  . My operating system is Lion 10.7.4.

I heard a "click" coming from the direction of where my charger and just before and now its not working.

• The light is not coming on the charger itself


• No power is shown be coming into the computer on the Desktop toolbar either, nor does my computer that there's a charger plugged in.


• I have tried the charger in a number of the different sockets around the apartment and still no joy


• The transformer "block" is cold

Could this be a s simple as a blown fuse in the plug or something else altogether?

I need to fix this asap. No power = no computer. All help much appreciated.

magsafe adapter not lighting up

Hi,

 

I've got a MBP Unibody from, perhaps, 2009.  It might be this model:

http://www.everymac.com/systems/apple/macbook_pro/specs/macbook-pro-core-2-duo-2 .66-aluminum-15-early-2009-unibody-specs.html

 

OS is 10.6.something.

 

I was using it yesterday without the magsafe adapter, on my lap, when I adjusted the screen a bit and then it went dark.  This has happened maybe twice in the past and I've been able to get it going again after letting it rest a few minutes, then plugging it back in with the magsafe adapter, and pressing on the power button.  So last night I did the same thing. 

 

It restarted fine but I noticed that the light on the adapter was not lit up properly - a faint green color did show up.  And of course the battery was not charging. 

 

I tried another adapter, no go.

 

I used both adapters on another macbook and both worked fine, bright green.  So I'm guessing it's not actually the adapter's fault.

 

I did a few things to try and remedy this:

 

a) I powered down and then powered up again.

 

b) reset the SMC

 

c) reset the PRAM

 

d) ran applejack (just for kicks)

 

Then I clicked at the top right on the battery icon to see this message: "Service Battery".

 

My MBP is no longer covered by Applecare and so I took out the battery just to see if I could power up the Mac to get some of my files before taking to a mac surgeon.  It won't power up without the battery at all.  I've got about 25% life left in the battery.  Does anyone thing that this is just a matter of getting a new battery??

 

Thanking you in advance........

MacBook A1278 (late 2008) MagSafe plugged in no power - help!

Hello all,

I have a MacBook late 2008 and it does not charge nor run off the MagSafe Power Adapter.

This appended the other day when I got the low battery warning on my MacBook. I unplugged and re-plugged the MagSafe power supply with no success.

The MagSafe light is very dim green when plugged (more visible in the dark). I shut down the computer as I had only 17% left on the battery. I left the MacBook plugged in a different outlet for the night. The morning after, it was still the same, not charging...

Then, I took an appointment at the MacBook Store and brought the MacBook to the store.

The employee at the Genius Bar was very helpful and here is what he said:

- The MagSafe charger adapter did charge another MacBook when plugged in.

- The possible culprit was the MagSafe board (dc-in board) and it would be somewhere around $60 to change.

So, I left the MacBook at the store to have the MagSafe board replace. He told me it would be done in three days.

Three days later, I got a call from an Apple Tech guy who told me I had to change the Logic Board, that the MagSafe board and the battery were ok. I asked him if his work guaranteed and he said no! Then he told me the cost to change the board would be 550$ Canadian dollars . I was holding to this MacBook as is and was planning to change it for a new one in maybe a year... I asked if he had some kind of trade-in program for my old MacBook and he told me : "the only thing we have is a student discount price".

Looking for an alternative, I found the iFixit website and videos but they sell the Logic Board for 700$ US!

I am very handy and willing to do some tests with the board (I have built almost all of my PCs ). I have looked at the tear down video and I am convinced I could achieve such a challenge... Is there any way to test the components on the Main Logic Board? Where and what should I look?

Here are the symptoms:

+ When plugged, the laptop does not charge, does not run on external power and nothing indicates that it is plugged (no charging meter icon).

+ The Power Adapter, MagSafe Board and the battery are known to be good.

+ The MagSafe Power Adapter has a very dim light green when plugged.

+ On the battery the MacBook works just fine (so, it is not related to the graphic card, CPU, memory, ...).

To me it looks like the power from the MagSafe board does not get into the Logic Board or is been short-circuited somewhere.

Here is a more complete description of the laptop:

Identifiers: Late 2008 Aluminum - MB467LL/A - MacBook5,1 - A1278 - 2254

"Unibody" MacBook "Core 2 Duo" (Late 2008/Aluminum)

os x mountain lion 10.8.2

CPU 2.4ghz

Ram 4Gb

HDD 250

Any help would be greatly appreciated!

MBP with almost full battery switches off if Magsafe removed.

I have an older MacbookPro (2.16ghz Intel Core, 17") . Its started behaving bizzarely today - with Magsafe connected, its shwoing a green light, and the battery is showing as 91% full, and not charging.

Checking the health settings on System Info shows its in pretty good shape.

The instant i remove the Magsafe connector, the Mac shuts off. No warning, just instant shut off.

 

I have reset the SMU following apples procedure of removing battery and power, holding power button for 5 secs before reconnecting everything and rebooting.

 

Nothing seems to have changed - the battery still refuses to charge and the Mac dies if the magsafe is removed.

 

Any ideas what the problem could be?

 

or how to cure it?

 

thanks

Why is there black stuff in my MagSafe power and MagSafe power connector?

I just got a brand new MacBook pro 13'' recently and I just realized there's seems to be black stuff in both my MagSafe power and connector and I have no Idea why and if or how I should clean it or what I would even clean it with? I have also noticed my battery doesn't last what it should. I checked my the activity monitor for high CPU's, my brightness is always on 50%, and the laptop is sufficiently charged when I begin to use it. Help?!
