So this is my second time posting the following, as it got deleted and completely disappeared (even from my own posts in my profile).

I own a 13" white 2007 MacBook:

Model Name: MacBook
Model Identifier: MacBook2,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 4 MB
Memory: 4 GB
Bus Speed: 667 MHz
Boot ROM Version: MB21.00A5.B07
SMC Version (system): 1.17f0

My girlfriend has a brand new MacBook Pro from this summer.
Both our computers suddenly started behaving weirdly about a week ago. I'm writing now on 5% batter power so I'll make it short. We have tried everything but our chargers just don't work properly. We have about 3 chargers and 5 heads/cords and all combinations have failed to yield result more than once. I have restarted my computer, taken the battery out, restarted PR-things and SMC and I have cleaned the heads and I have even tried to install an update from Apple but it told me my mac didn't need this update.
So what the * is wrong with the magsafes? It's a real pain because we can have them working for many hours as long as we don't touch them - then if we move or want to unplug the charger for even just 1 second, they might not work again for 2 days.

So please help us. We're both writing our BA theses and need our computers working. Thanks!

PS: I received a message telling me this was a duplicate but it is not the same issue addressed by most people here because we are using both L and T shaped magsafes and it makes absolutely no difference. Both behave stupidly.

    I swear I'm about to go insane. So my computer just died at 0% and I plugged the charger in and out maybe 50 times in different orders, spots in the house. Then suddenly i started working. I'm sitting here with 28% and BOOM, stops working OUT OF NO F** WHERE.

    If this was happening a few hundred years ago I would say that my computer was possessed by the devil himself.

    Everything you're mentioning is classic symptoms of a battery that needs to be replaced. I highly suggest you do so.

    Hmm. An oddball question, but have you guys seen the same troubles if you're at someone else's house?

    She has had the same problems at school and I have had the same problems at work - with the same 3-4 magsafes we have.

    Does anyone know if there is an update fix to address issues associated with new (supposedly improved) power adapters NOT lighting / charging with a MacBook running OX S 10.4.11? I find update fixes (SMC Firmware Update 1.4) at apple.com for OX S 10.5.8 and 10.6.4 and later only. Thanks.

    At 1366 cycles your battery should be replaced, hers I'm not so sure but maybe. Get a new battery for yours and see how the Magsafes behave, take hers to the Apple Store and let them diagnose.

    Hi, I am having exactly the same issues with my new Macbook Pro 15" (2011) . Tried different outlet at different locations (home and work) and I got different results; sometimes it works sometimes it doesn't. Did you get resolution for this issue?

    Same problem, MBA 11" Juli 2011. Laptop sometimes charges, but most often not. Friends 60w Magsafe works, own 45w Magsafe works on friends MBP, no signs of wear on adapter. Tried SMC reset, with no effect.

    I am having the same problem with a MacBook Pro 13, intermittent charging, any solution yet?

  • Stin0 Level 1 Level 1

    Hi,  After I had it checked at the Apple store Genius desk, a new adapter fixed it for me.

    I had this problem 2 months after I bought a MBP in 2013. I followed theese steps http://support.apple.com/kb/ts1713 and found that there was a little metal speck in the magsafe port on the laptop. I cleaned it with a q-tip and the problem was solved.
