MacBook Pro does not charge

I feel that this question is asked a million times, but I'd like to walk you guys through my situation.

Retina Macbook Pro 2013 (out of warranty of course) in excellent condition. Fully updated software.

A year ago, I had a problem with intermittent loading. Of course, I went online and followed the instructions on resetting the SMC. Sometimes it would work, other times not. Sometimes the software updates would trigger the loader to activate when the system is restarted. I would like to try various outlets around the House with none of them work. Is my next laptop Apple certified tech and is it charged out of their fine magsafe charger. I thought, cool, I'll buy a new charger. I understand House and it does not load. This process is repeated for a year. I could get the new charger or one laptop comes with to work. After a time I kind of nailed what I could warm up the bricks of charger with the warmth of the body and get them to come. Kind of weird but it worked... sometimes. If fast-forward a couple of weeks. I could not the computer to load at all. I took a day and I have tried everything in the book:

  • Resetting the SMC
  • Try the different points of sale
  • Warming of the charger
  • Update the system software
  • Leaving the charger unplugged for hours and try again (it of in case of dirty power coming out walls and locks the charger?)

So I took it to my local tech again and it started to load automatically off not only their Chargers, but both of my friends... He performs a reset SMC, talking about me on the House of tension circuits and sends me on my way, pretty confusing. I get it home and charge the battery to 100%, but two weeks later here I am again with a Macbook Pro which does not load... This time I even tried to load out of a UPS System.

I consider myself very savvy computer, especially with the Mac. I have a decent background in electrical systems of the classes I took in high school and college. I read the manuals, I do my homework, I take excellent care of my devices. But honestly, *...

Any ideas would be appreciated. I'll take in addition to anyway. My local tech makes an appointment and I can't get an appointment of bar genius until next week. I have a laptop dead at this time.

I do my homework,

Certainly, you made and excluded from all the obvious concerns besides a few non-obvious. The only remaining uncertainty, I can suggest is your domestic food, since your Mac seems to load very well everywhere else. Power of the Mac adapter intelligently will close if it detects bad quality. Other than to call it 'noise' Apple is characteristically silent when it comes to debate just what are the parameters it uses to accomplish this.

Most inverters do much through food. An alternative is to use a 'real online' or 'double conversion online' UPS, which are more expensive because they are still deriving their battery power, thus isolating their input and output power. Another esoteric alternative that I don't necessarily recommend is to use a ferroresonnant transformer. They are inherently inefficient, but concretely achieve isolation even.

    Try:

    Try these in order to test your system after each see if it is back to normal:

    1. a. reset the PRAM and NVRAM on your Mac.

    2. restart the computer in Safe Mode, and then restart again, normally. If this does not help, then:

    COMMAND and R keys until it appears the Utilities menu screen. You can also restart the

    computer and after the ringing, press and hold down the OPTION key until the Boot Manager

    the screen appears. Select the Recovery HD and click on the arrow pointing down.

    3 fix the hard disk and permissions: at startup, select drive in the Utilities menu utility. Repair hard disk and permissions as follows.

    When the recovery menu appears, select disk utility. After that the charges of THE select your entry from hard drive (mfgr.

  • iPad Pro does not charge

    My iPad Pro (10.0.2) says not charging when connected to the nearest 4th USB port of lightning on my iMac OSX end 2015 10.11.6. Another thing that I connect it works so there is nothing wrong with this port.

    However, my iPad charges when it is connected to the other 3 USB ports. Tried other Apple cables, restarted my iMac and reset my iPad.

    Basically, it's not the iPad, and it's not USB port cuz that they both work when plugged in with something else. It's just the 2 at the same time with the other who do not work.

    I'm so confused. Does anyone else have this problem?

    Hello. It seems that the charge voltage/current monitoring software has been changed in iOS 10. It is much more sensitive. Your device's charge when says "do not load", but he is in charge, probably faster when it shows the Flash. See the iPad is cool the computer after an upgrade to iOS 10 batches of a discussion of this issue.

  • Excel files created on a MacBook Pro does not open on PC

    Hello

    I created a large number of worksheets with the help of Office 365 for MAC on my MacBook Pro (OS X - El Capitan 10.11.6) and then transfer them to a computer that uses Office 2007.  Since week last I was able to open spreadsheets on my PC but I get a warning on the PC that said to check the file comes from a reliable source because that might have viruses that are dangerous for your PC.  I click Open anyway, and the file will open IF you do not see the data.  You do not see the cells.  However, you can see the number of cells and worksheet data in the Ribbon at the top of the screen.

    I tried:

    various parts and get the same problem.

    Reinstall Office 365 on my Mac and Office 2007 on the PC.  No change.

    Change the version of xlsx to an earlier version.  No change.

    I looked the preferences on my Mac to see if something has changed.  Nothing has changed.

    I have installed a new software

    I did not put up-to-date Office 365 or my Mac software

    Does anyone have any suggestions on what I should look on my MAC?  I posted questions about the Microsoft PC to see if there a problem with 365 I really dislike?  Help.  I have a spreadsheet that is massive, I don't want to have to recreate on a PC, simply because I can't open it.

    Thank you

    The problem is Office 2007 on PC. You must either 2010 or higher without converter. 2010 and more have an automatic converter for the most recent files, but 2007 will not work. Go to the Microsoft website and you should be able to find the converter here. When the college so I have to work changed in 2010, had to add a tag to our emails with a link to the converter for people using older versions of Office.

    After reading your post again, you should be able to save the spreadsheet as a version of Office 97-2003 and be able to open it in Office 2007, but if you still have difficulties, this add-on for Office 2007 must repair.

    You can go there. I knew what to look for.  https://www.Microsoft.com/en-GB/download/details.aspx?ID=3

  • MacBook Pro does not start. Tried a lot of things, but no luck. Ideas?

    MacBook Pro mid 2012 does not start. Getting the various screens of gray. When trying to make right boot, get flashing folder.

    Other things does not: recovery of OS X, without failure, verbose mode, Boot Manager, single-user mode. IRA to the re-establishment of the Internet, enter the password, stall (error - 2002F-).

    Tried to reset the memory NVRAM and SMC, but nothing.

    Tried with the new hard drive, but accurate results same with the old hard drive (I thought that the old hard drive can be damaged, so got a new one, but get the same results).

    Any ideas? Could go to the Apple service center, but closer to here where I am is 3 hours away.

    Should note that there are many attempts Mac starts up fine (by divine intervention I think), so saved all all on, but after computer use as usual for an hour (especially Internet browsing using Safari and Chrome), computer slowed to snail pace, so tried to restart but still got results above.

    Any help or ideas greatly appreciated. Thank you!

  • Printer HP C310 hung wireless for MacBook Pro does not allow me to choose printing options.

    Just replaced my MacBook with a MacBook Pro (NICE!) I have an iMac that has my C310 printer Photo HP Smart connected on it.

    Pulled up the new laptop and it was immediately find and access the right printer YAY?

    I run an online business and am constantly printing on purchases (portable) coming in. My PROBLEM is that I am not given ALL the printing preferences options, all prints off the coast in color I don't need (price wise - considered ink as)

    The options are given to me on the iMac I think that since it is literally connected to it. However, on my old MacBook that I had a few days ago the options all came when I went to print (wireless connection as is the new MBP).

    Any thoughts? I tried to click on anything whatever possible in screen printing that is displayed when sending to the printer and he basically tells me what I'm doing not giving options for change to the basic black that I need.

    Thanks in advance

    For starters, you can remove the software and reinstall it from the link provided below? Let me know how the printer responds and if these options are put at your disposal once more.
