"Hi!

I've just had the exact same problem as Dirk had, on my MBP 15 Mid 2009 and its genuine battery: no charge, magsafe LED always green, battery stuck @ 40% & MBP would only start with the power cord connected. It would shut down instantly when removing Magsafe.

Coconut battery was pretty confident regarding the good condition of my battery, but still it wasn't operational at all!

I've tried all the resets you could imagine (SMC, PRAM & NVRAM & so on...) and all the fingers/keyboard combinations the guys at Apple came up with, without any success!

I finally found this post.

All my little ""mac world"" was about to collapse when I read Dan's answer > Logic board problem (no offense Dan) - but I kept reading. Hope came back when I read Andreas' contribution.

I couldn't swap battery like Andreas did, but I tried to remove it from the mac (without any pentalobe screwdrivers - that's a challenge).

I started the mac on power supply without no battery fitted: booted up fine.

I finally reinstalled the battery in the MBP and powered it without any power supply: AND IT WORKED !

It looks like the battery needed a ""hard reset"" SMC couldn't offer.

Anyway, I hope this trick will help some of you.

This message is not aiming at trying to determine who's right and who's wrong, I only want to share my experience.

Big kiss from Paris.

"Dan - I felt bad about using the word ""wrong"" from the moment I submitted the post...let´s blame it on my English skills, I definitly did not want to deny that your conclusion in most of the cases is right. I just wanted to share my experience, in which checking the battery saved me from dumping a MacBook Pro that might be outdated but with SSD and FusionDrive still beats the new MacBook of my wife...Your explanaition (cheap battery lying to coconutBattery) however makes perfect sense...

So lets sum up: Check your battery, if problem is not solved, repair/replace the logic board....

Greetings from Munich,

Andreas"

"I've been trying everything.

Magsafe stay's green, when powering up de machine (Macbook 6.1) with the battery connected, I hear the chime, see the apple logo on the screen and than the machine switches off.

When unplugging the Magsafe, holding the power button for 10 secs, connect the magsafe while still holding down the power button for 10 secs. once more hitting the power button, the machine swithes on with vens full speed. With or without battery connected, the battery sign in the displays shows a black cross and is not charging. Magsafe stay's green

When battery is connected, I need to do SMC reset, than unplug the battery, hit the power button in order to switch on the machine. Magsafe stay's green.

I noticed that the Magsafe green light blink's off and on every 6 secs"

"Had similar problems. MegaSafe would be green, and laptop would power on, but the battery icon on the screen had an ""X"" through it as it was not charging. Also found that pressing the battery indicator button did not produce any results.

Ended up replacing the Battery indicator board as the ribbon cable attached to the logic board was fragile. Once replaced, laptop started charging properly."
