my macbook pro does not

my macbook pro doesn't turn on. It makes a noise and the light turns on but then turns off. Nothing on the screen. Can anyone help?


Is the noise, a chime or something else?  You can try. A landau SMC redefined and. there are also R command to get to recovery where you can run the utilities disk to check/repair the disk or reinstall it.  Do you know what year the MBP? Is the screen black or white?

  • 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.

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


    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.

  • MacBook Pro does not start safe mode or recovery mode without start up

    I use my MacBook Pro almost daily for several months now, and all of a sudden I stopped and start it up to a kernel panic (so it seems) who never lets me start normally, safe mode is a nothing helps. Recovery mode does not start, and when I try to use an external drive usb in the selection of drive it will appear. I don't know what to do more and I'm stuck. I'm not able to get in all the menus, so all I have is these pictures of panic before it restarts. Post picture soon submit iPhone photo.

    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-).

  • My MacBook Pro does not start all of a sudden upward


    I turned my MacBook Pro yesterday and when I went to start it up again today, I pushed the powerbutton comes the startup sound and clear grey screen with an Apple comes up with a progressbar under. about a cm from the bar gets full and then a code appears on the screen for a few seconds, then the computer tries again to restart and it circulates in a loop. I took a photo of the code that is displayed for a few seconds and attached to it.

    What should do?

    I have timemachine copies the MacBook on my TimeCapsule, but I have no idea how to use when the computer refuses to start.


    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.

    b. Macs with Intel processors: reset of the controller (SMC) system management

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

    HD recovery start: restart the computer after the ring, press on and hold the

    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. ID and car size) in the list on the left.  In the status area, you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is faulty or has failed. (State SMART is not reported on external drives Firewire or USB). If the drive is "verified", then select your OS X volume in the list on the left (subentries under the entry for the road), click the first aid tab, then click the repair disk button. If THE reports any errors that have been corrected, and then run repair disk again until no errors are reported. If no errors are reported, click repair permissions. Wait until the operation is complete, then exit FROM and return to the main menu. Select restart from the Apple menu.

    4 reinstall the 10.10.5 update: OS X Yosemite 10.10.5 Combo Update.

    5 reinstall OS X: Reboot of HD recovery Select reinstall OS X in the Utilities menu, then click on the continue button.

         Reinstall the 10.10.5 Update: OS X Yosemite 10.10.5 Combo update, if necessary.

    Note : You will need an active Internet connection. I suggest to use Ethernet if possible because it's three times faster than wireless.

  • 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

    iMac osx 10.7.5
    MacBookPro with Retina

    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.


  • Mid-2012 retina Macbook Pro does not stop

    My mid-2012 retina Macbook Pro running El Capitan (v 10.11.5) won't shut down or restart. Taken to the Apple store where they ran diagnostics on it and can't find anything wrong. Suggested I have reinstall the OS. I reinstalled, then backed up with Time Machine. The problem persists.

    I think I can get a report of incidents which may be helpful, although I've never shared before. To include or omit any information would be helpful.

    Especially the crash report reads "identifier" and "responsible" as: "". Type 'Exception' is ' EXC_BAD_ACCESS (SIGSEGV) "and the" subject crashed ' reads ' queue 5 sending: DispEventQueue "."

    Any help would be appreciated.

    I see now mid-2012 retina Macbook Pro El Capitan (v 10.11.5) running.

    It does nothing?  I think I would resume.

    They run the VST (video-Test systems)?  If this isn't the case, I'll ask for it.

  • MacBook Pro does not detect monitor Dell through CDM

    Guys, a few weeks ago I asked a question if bolt of lightning 2 CDM-compatible monitors. You guys lied. I got the Dell P2715Q today and I have connected to the computer with the USB cable I had Plug and cable thunderbolt. I did everything, but my Mac has not detected even if I pressed the "Detect" button in the system preferably several times. I restarted my computer and still nothing happens. The monitor speaks to me of * like 'Enter in Safe Mode' then what I do now? What the * Apple? You create all by yourself? Your useless thunderbolt screen is worse than the air show 2011 MB! Help guys!

    What USB connection?  There is no "monitor" for this Dell Monitor USB connection.  The USB connection is a USB hub built into the monitor for other devices.  You must select one of the following values: DP, HDMI or mini-DP.

    I'm sitting on my right now uses a new MacBook Pro computer w/Retina.  It is connected via the Thunderbolt port to a Dell U2715H using the connection of the RFP at the back.  No problem at all.  I used this type of connection for the most recent years (previously an old MacBook Pro, 2011 model).
