My power cord will not charge my battery or even maintain the Macbook pro when I am in my mobile office!

Any one else having issues with the 60w MagSafe Power Cord not working when connected to an inverter or Generator?  My Inverter is a 2000w modified sine wave 12vDC-110AC unit.  The generator is a 6 KW diesel powered unit.  Both of these units are functioning and are in use powering other devices so I am at a loss as to what the problem might be!  I have been using the inverter for the last year to power a PC Laptop, and a small refrigerator, the last of which is still in use, but the PC died.  The generator powers a microwave without issue, thus I feel certain there is no problem with either power source.

USE FOLDING DUAL PRONGED ADAPTER FOR BEST RESULTS!!!  NOT THE GROUNDED EXTENSION...
It seems as though the solution in my case was to eliminate the 3 pronged (Grounded) Charge cord extension from the MagSafe Power Cord, use the 2 pronged folding plug instead and now I have the ability to charge the unit from either my (MSW) Inverter or my Generator without any failure!  Too bad I bought 2 more inverters and wasted a trip to an Apple Store as well as an hour of Phone Tech Support before figuring it out on my own!  Good Luck!

    Does the connecter seem to be making good contact?  Is yours a model with a replaceable batttery or not?
    Might have to visit an Apple Retail store genius bar, or authorized repair and have them check out the battery to see if it has failed.

    If you have all your music on the cmputer then i would connect up my phone uncheck the Sync Music option and apply.
    This should take all the music off your phone .Then you can resync the music back on to it.
    If this doesn't work maybe a restore to factory settings and start from scratch is the way to go

    Inspect the charging port area for dirt/debris/fluff build-up that may be preventing a good connection and use a wooden toothpick, soft clean toothbrush, or a can of compressed air to clean it. Also look for bent or broken pins. Try another cable and/or charger block (be sure to always use a genuine Apple certified brand) in a known good outlet. If you're using a USB port, try another port. If you're using a hub, try a direct connection. If you're using a USB port in the front of a desktop computer, try one in the back. If all these fail, make an appointment at your nearest Genius Bar to have the device evaluated.

    Unplug it from the Mac and the wall and let it sit for 20 minutes.  Try it again.  If it still doesn't work take it back to the Apple store.

    can you change battery, SSD Harddrive of the macbook pro retina

    Officially? No and No.
    Unofficially, OWC has come out with some suitably expensive replacement storage cards that can substitute the "drive" on the Retina, but that's about it.  You're stuck with what you bought for life.
    Battery and RAM are soldered and glued on, can't be replaced without replacing the whole logic board.

  • TS3499 macbook recognises but will not charge new battery

    I was advised to buy a new charger last week and have just been advised by an apple employee to buy a new battery for my MacBook 2009 and i am having the same issue as my old battery.
    The Mac reconognises the battery but will not charge or run off the battery.
    Just spent £150 in total on new charger and battery but still having the same problem as before.
    I have downloaded the firmware update but my Mac is already running the latest software.

  • Brand new cord will not charge it?

    Okay, so this morning when my mac was charging my dad moved it from the couch to the table, and in the process moved the extension cable it was connected to to the floor, my 15 week old rabbit decided that my lovely white power adapter looked tasty and decided to chew it. I came back to my computer and picked up the long white cord because i was going to move it so my rabbit wouldnt chew it and discovered he already had by the big chew marks he had made where the wires were exposed were sparking. Long story short, i took it to my local apple store they told me it wasnt covered, i payed $89AUD for a new one and got on with my life. I used my mac this afternoon without it plugged in as it was allready charged from this morning. I plugged it in tonight and realised that it wasnt charging. On my bar it says (Not Charging) and then on the drop menu it says.
    Battery Is Not Charging
    Power Source; Power Adapter
    Its keeping it working, but it isnt charging it? My old one and my new one are both 60W. I have tried plugging it into many different places none work. What do you think is wrong?

    There have been a lot of variants of the MacBook Pro since its introduction in 2006. One variant (can't remember which), required a software solution to work with the newer "L" shaped power connectors. Without knowing which you have, the best thing is to see if Software Updates offers you a patch.
    There are also reports of some of the older, silver-key MBPs having a problem with the fit of the new adaptors.
    Lacking that, I'd take the computer and the new adaptor to an Apple Store or AASP and stand there until they can provide an adaptor that works. Leave the rabbit at home.
    Man! I though cats were tough on computer cables!

  • IPad will not charge after IOS 7 update unless the brightness is dimmed,..Why?

    I recently updated my 4th gen IPad 64Gb to ios7. Previous to the update I loved my iPad and it worked flawlessly. Since updating the iPad now will not charge unless I dim the brightness of the screen, and slowly when it does. Why? Is there a way to remedy this?

    I do not know if it's iOS7 related or not. My 2 is still working. However, my first 2 was returned to best buy after the charging port on it died. So that can happen. ANd it happens with little to no warning. CHarges monday, doesn't on tuesday.
    As far as I know the issues with 'unsigned' lightning devices is just the cable, not the power brick, but there's no official word (nor do I expect one)
    Lightning cables have a little chip in them and if that chip isn't signed by Apple then your device kicks up an error but should still work.
    However since this is an iPad 2, that's not the case since 2's use 30 pin chargers, not lightning.
    Usually when a 2 doesn't charge, common troubleshooting is to swap out the charger, cable and outlet, to confirm or rule those out. Also to do the reset. (the soft reset that's holding down the sleep and home keys until it reboots). Also to look in and blow out the port in case there's some lint or such in there.
    Usually those things fixes it. If not, then it could be the port.

  • My iPhone 4 will charge on a wall socket but WILL NOT charge on computer or even connect to the computer and show up???

    My iPhone 4 will not connect to my MacBookPro. It will not charge on my MacBookPro, but it will charge on a wall socket and it will play music in a 3rd party speaker system??
