Flashing orange to green?

Mine does this at random intervals as well, and I've only really noticed it since I upgraded to Leopard. It's driving me mad!

My Macbook Pro power adapter just starting doing the same thing. What the heck is the deal...With either a full charge or while charging (just from plugging and unplugging so always almost charged), the LED blinks 5 seconds GREEN then 5 seconds ORANGE (AMBER).

It's charging, pins don't seem to be stuck.

Just installed the Battery Update (1.3), seems exactly the same. I'm going to try the SMC reset when I get home.

I'm having the same issue on my Macbook. It will sometimes flash directly from green to orange and back again, constantly. Sometimes, if I leave it unplugged for a few minutes, it will charge back up and then remain green. Other times, it works perfectly to begin with. I'm pretty good about training my battery once a month, and I don't have any stuck pins, etc.

Any other ideas would be welcome. It's not a huge deal, but it is mildly annoying.

Mine has just started doing this too. It has also started cutting out at around 77% - suddenly the computer switches off without warning or proper shutdown & won't start back up again.

My other battery is still working fine, so it's obviously a problem with the battery itself.
It has about 150 cycles, so should have plenty of life left in it I'd have thought.

Has anyone found a solution to this?
Thanks, Jon.

I've started having this happen too.

What are the steps I need to take please in resolving the problems.

I've seen the cable go from orange to green even when its 97% charged.

The laptop justs stops and turns itself off too.

This same thing has been happening to me. It started after the 10.5.1 update. I get the intermittent green-amber flashing on the charger. I can never get over about 95% charge before this occurs. Not only does this thing not charge all the way, I can't get it to discharge. The laptop shuts off (no warning or anything) around 30% charge. I hope this gets fixed in a hurry. My Macbook Pro isn't very mobile at the moment. 😟

Same thing with mine. I can never fully discharge due to the instant off after 30 minutes of use. It flashes about 60 times per minute. My mini logger shows it cycling over and over.


( I posted this on another thread and then found this one. Sorry for the similar replies).

Ok I became so frustrated with this doing it during class (caused my screen to darken and brighten with every cycle), that I took the battery out completely. It was about 75% at the time I took it out. It stayed out for about 2 hours. When I put it back in I have had no issues with the cycling. It now works just fine.

It started behaving correctly a few days ago (no more flashing and fully charging the battery). But it started up again today. This doesn't seem to be something that occurs all the time. I just hope this isn't destroying my battery.

I have the same fear: I hope it's not destroying my battery! Or hurting something else. Has anyone gone into the an Apple Store or called Applecare? I am just getting into finals, so I will postpone my visit until mid December... If by then no one else has paid a visit to Applecare, I will post my experience.

I would honestly get it checked right away. I contacted Applecare yesterday, and we're not sure how, but my six month old battery dropped from 5200 mAh to about 1500 since I installed Leopard. Go into your System Profiler and see if this is happening to you too! The folks at Apple were kind enough to send me a new battery, and I'll post here if the problem recurs with the new one.

I went into the Apple Store and the tech guy thought the issue could be 2 things:

1) The battery, which is what we all suspected.
2) The logicboard, something I had not considered.

Unfortunately, they did not have ANY spare batteries to test in my MBP, so they are ordering one now and we will see if that resolves the issue... If not, then the logicboard might be at fault; which would not be a good thing!

I will post an update when I go into the store again.

I had the same issue 4 months ago with a MB, the MAh was slowly dropping off and the battery only had 53 cycles on it. The charger would flash green, amber and would never fully charge the battery.
There is a little know recall on MB batteries, I'll find the link again and post it. Anyway took the MP to Apple with a print out of the recall, I got a new battery.

Thanks for the postings White Dog. I had done the battery upgrade and my battery was not one of the model numbers recalled.

I have updates on my replacement process. First, I have a new symptom to add: when discharging the malfunctioning battery, when mine got around 10% it would just shut off without properly going to sleep mode. SO I think that was a sign of calibration issues.

Anyways, I took in my malfunctioning Sony battery and received a new SMP Brand battery that upon initial calibration seems to be working great. The original power rating was 5455 mAh, which seemed pretty good to me. I will post if there are any issues, but it appears a replaced battery is the solution...
