MacBook Pro does not start. Pls help

Hello

When I turn on my mac, a white screen with a record (with an exclamation mark on it) appears.

It flashes on the screen several times, and then the mac turns off.

Anyone know what it is?

Is that what you see:

If the included directions do not work for you, suggest the EXACT year/model of your MBP.

Ciao.

    Hello

    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:

    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.

    ITunes on my old MacBook Pro does not recognize my new Iphone... but apparently I can't download the new version of Itunes to this model of MacBook Pro? (according to the message that I get)... So I can't transfer my photos / apps / data, etc., for my new phone... Does anyone have advice?

    It is not so much the Macbook Pro model as what operating system your help, for example, if you're running Lion and trying to download Itunes for El Captian. Impossible to run your operating system which. Updates for your system come from apple. Ether through a software update or the Apple app store. Generally, you will receive a notification if an update is available. What operating system you're running and what Iphone model? IPhone 6plus has for example need OS 10.7.5 or newer.

  • my epson dx4050 will not work or open I use wind 7 now, but it does not work pls help

    my epson dx4050 will not work or open I use wind 7 now, but it does not work pls help

    Because your message was clearly not your comments on the web site of MIcrosft responses, I have he left the comment forum in the forum 'Hardware and drivers' Windows 7.

    When you say it "will not open', do you mean physically or you want to tell the printer object in the printers and devices folder does not open when you double-click it?

    Have you tried to delete the printer and add it again?

    He has already worked?  If so, have you changed between yesterday and today?  The device is supposed to be compatible with Windows 7 and should not need a separate driver, but if you have Windows 7 32 - bit, you can try using the driver on the Epson website.
    http://eSupport.Epson-Europe.com/FileDetails.aspx?LNG=en-GB&data=lkuCfcvA9cw77whFcRdwis4JOQH9mtNd&ID=324678

    How do you connect to the Stylus DX4050?  It is USB, wired network or wireless network?  The documentation says it is USB, but I connected USB printers to the network, then maybe you have as well.

    The more details you provide on your printer and your system, the better people can help you.

  • Tablet Dell coming 8 Pro does not start

    Hello

    The Tablet is only about a year. And I've kept it's safe and sound, no damages or drops. Nothing.

    But yesterday morning when I got it, he went to sea and no matter what I do, it does not start!

    I press and hold the start buttong. Nada. I even press the windows key or was desperate enough to press the volume even toggles!

    I thought that maybe the load isn't enough. So I let it charge overnight. Still nothing.

    He used to have a small problem before that sometimes he used to take a few minutes to actually boot (startup). But it's random and many times, it was when an update has been installed. But not always.

    But this time, he stayed off the coast and after more than 24 hours, does not illuminate!

    What should I do?

    Thank you

    I think just, I solved this problem. Make absolutely certain that you are using the supplied with your coming Pro USB wall wart, similar and ordinary phone chargers don't work reliably and sometimes not at all! There will be a sticker on the side of her windows. The Pro should need more energy than what is normally fed by normal phone chargers. I hope this helps!

    Also, I think that light orange/red momentary while that push the power button is actually an indicator of battery flat (as crazy as it sounds). These types of batteries are supposed to be completely empty as it will ruin their fast enough, so they are designed to power off with a few charges left to protect themselves to be completely discharged.
