I am a bit of an Apple hoarder. I have four laptops and 5 desktops dating all the way back to some G3s... Anyways I have three magsafe adapters here, and only one "L" shaped one. This L shaped one, for whatever reason, will not charge my laptop unless I unplug it and plug it back in if it sits around unplugged for an hour or more...

 

Is it defective or is this some kind of safety feature or something?

 

Kind of annoying that I have to go crawl/bend down unplig/replug the adapter everytime...

Mac Pro, Mac OS X (10.6.8)

    Be sure to use the right one. The latest 15" and 17" Macs have an 85W adapter, smaller and older models have adapters with less power. If using the wrong adapter, it may be overloading and shutting down as a protective measure. On older Macs, the L adapter required a software update to run properly.

     

    Last but not least, an SMC reset may also help in the newer Macs, especially if hobbled with that fat cat called Lion: http://support.apple.com/kb/HT3964

    ds store, greetings:  Regarding your section on the Apple Hardware Test.  Pre Lion MBPs do not need an Internet connection.  All that is necessary is the appropriate original install disk.

     

    If you make that addition/correction you will be entitled to two blue stars.

    The AHT started residing in the HDD starting from the Early 2008 model. An AASP I know and I did the tests way back then to confirm. Of course, if the drive went kaput, the install media was the only recourse. In the media-less Lion and post-Lion world, Internet becomes a necessity.

    I have a 2006 MBP that can use the 'L' shaped adapter with no problems and I am not aware of any software updates that were installed to accommodate same.  Perhaps su excelencia Courcoul knows something I don't or he is ingesting some local organic substance.

     

    It is also my understanding that no harm will come to any MBP using the 85 watt power adapter, but the 60 watt has insufficient power and is not appropriate for the 15"-17" MBPs.  If I am incorrect, educate me.

     

    The power adapter has no brains so the unusual behavior has to be in your MBP.  What are the wattages of your adapters, especially the 'L' shaped one?

     

    Ciao.

    Mi amigo Ogelthorpe, no I am not partaking of any of the mind enhancing substances the local narcos are so keen in providing, thank you. My now-dead Early 2008 MBP bought in April 2008 came with a straight-white MagSafe T-connector. Awhile later, Apple came out with the L-connectors AND put out an update so the older Macs like mine would know how to deal with it and flash the lights correctly. Yours probably got patched as a side effect in one of the major updates.

     

    As for Mr. Flash, just in case this helps, have you thoroughly cleaned the MagSafe connector, male and female? Another forum visitor had scads of power problems that were magically resolved when he cleaned the thing.  http://support.apple.com/kb/TS1713

    su excelencia Courcoul, saludos;  You just forced me to shut down my 2010 MBP and restart it with the 'D' key and lo and behold, the AHT was initiated.  Then I tried the same on the 2006 and got the normal desktop.  Can you determine with 100% certitude when this phenomenon occurred (Early or late 2008)?  If you can, you will be awarded two blue stars.

     

    Ciao.

    Señor Ogelthorpe, when I received mine in 2008, Friday before Semana Santa, quickly discovered the self-loading AHT. Told as much to an AASP I visit, who insisted the DVD was indispensable. Off we went and did every Mac he had in the shop and the storefront. Only the newest ones like mine did not need the DVD. Early 2008 model, last of the non-unibodies. Like the old geezer in Titanic, all that now lives only in my memory, cause the Mac's logic board croaked in Dec. 2011.

     

    Today, my Late 2001 media-less Lion MBP will load the on-disk AHT if I press D and the Internet AHT if I press Option-D.

     

    Saludos!
