2015 mbp has lost all power

Plugged my iPod Classic 60 GB to try to synchronize with my iCloud library. ITunes has shown, but wouldn't a synchronization and then it wouldn't show it, so I restarted computer. IPod is connected and then the computer would not start. Not nothing behaves as if there is no power at all. The fact to unplug iPod did nothing. Any suggestions?

Try resetting the SMC http://support.apple.com/kb/ht3964

It is the following:

Stop the Mac.

Plug the MagSafe or USB - C adapter to a power source and to your Mac.

Use the built-in keyboard, press on and hold the shift-control-Option on the left side of the keyboard, then press the power button at the same time. Letting go at the same time. A very passive movement. It seems that nothing happened.

Try resetting the NVRAM/PRAM http://support.apple.com/kb/ht1379 memory

It is the following:

Stop your Mac.

Locate and hold the following keys on the keyboard: command (⌘), Option, P, and R.

  • iPhoto has lost all the additions from June 2015 to 21 Feb 1016. Tried to restore from Time Machine, it still has the gap.

    The date is February 24, 2016.

    I'm studying me ways to copy the library iPhoto in full on an external drive. I've been in the Finder > my username > photos, simply by looking at the dates, and I'm not aware that I made any changes.

    I was adding a handful of photos every day for the last week or two.

    I noticed that the file system is not quite as it was a week ago, and it seems that the last event is June 29, 2015, up to an import on February 22, 2016. In other words, it seems iPhoto has restored to its state of June 2015 then accepted imports from February 2016. I had not yet been in Time Machine!

    In the Finder > username > images, from now on, I see there: -.

    "Today."

    "iPhoto Library", type - package, with a white page icon folded, created may 2012, 30.8 GB, modified today, version 9.4.3.

    'iPhoto Library (original)', kind - iPhoto Library, with a colored icon, created may 2012, 27.46 GB, today, no modified version mentioned.

    «Past 7 days»

    "iPhoto Library (2 originals)" type - package, with a blank icon page folded, created may 2012, 30,77 GB, modified February 19, 2016 (its Feb 24 today), version 9.4.3

    In Time Machine, I restored version Feb 19, I find that the library was complete at this date, but the library has the same gap to date.

    I would be grateful for any suggestion. I didn't have it backed up to the cloud. Please have mercy, I'm not that tech-letter, so I would appreciate instructions step by step to the intermediate level.

    A big thank you Doug - greetings-

    You do not use the finder in any way with your iPHoto photos - when you launch iPhoto see you - especially in the last import, and last month "n"?

  • What happened today? (18.October.2015) Firefox has removed all add-ons "or" bring to install

    Hi all
    So, today, my father called me to help you, because he could not start Firefox.
    After awhile, he showed that Firefox has crashed and the previous session could not be retrieved.
    So we restarted Firefox and discovered, that all modules have been removed, then Firefox seems to work normally.
    I thought that it's a misfortuned event and I left, because Firefox seems to work normally after that.

    Later that night, I had a similar thing happens to me, I start Firefox, and it opens with the default view (I use modules that modify that) with 11 tabs, one for the page by default, and on the other, asking me if I want to install an add-on said or delete it. (all 10 modules were those that I installed the way back and there is no additional/unknown modules)

    So I wanted to ask if someone could tell me what could have happened. I could not find official news that something has gone wrong. Was it a coincidence that we both had a similar, if not the same strange problem?
    I'm using Firefox 40.0.3 and my dad uses Firefox 41.0.2 (current version), we both use different computers and we both use different routers.

    Thank you in advance!

    BIG EDIT:
    So apparently there was a big broad cyber attack on the 18th. October 2015, my father the other laptop (not the PC I mentioned) may not even load Windows more.
    I guess that this is not a specific question of Firefox more, so this thread can be closed.

  • Thunderbird has lost all my accounts and settings

    I have been using T-bird for years with only the default profile. I have my personal Setup account separately 2 corporate accounts that are grouped in the local folders.

    Yesterday, when I rebooted and started the T-bird, it was as if I had never set up all the accounts. There is no folder or messages and all my accounts had disappeared.

    I checked the C:\Users\Owner\AppData\Roaming\Thunderbird\Profiles\xxxxxxxx.default and the files are still there. It is just that my default profile is not to use them, even if the correct folder is displayed when I go to help/troubleshooting and click on 'display the folder '.

    I suspect a main index file (prefs.js) is damaged or has been deleted, which should bind the T-bird to all other files in my profile. How to make T-bird to reconnect with my data files of this profile?

    Found my own answer, even though none of the research or the pages of support.mozilla.org were of no use either.

    Google found Disappearing mail - MozillaZine Knowledge Base led me to retrieve a profile that suddenly disappeared - MozillaZine Knowledge Base

    In this last article, I found this text

    • A quick way to say what problem you are suffering from is to look at your personal address book in Thunderbird. If it seems correct, proceed to the section corrupted or empty prefs.js . Otherwise, follow the instructions in the lost profile section.

    After going to the section corrupt prefs.js or empty , I found this is my answer:

    • Otherwise, you need to rebuild prefs.js. You can do this by creating the same accounts again in the existing profile and Thunderbird to use directories that contain always the missing mail, by this article that Recovering deleted accounts e-mail - MozillaZine Knowledge Base. Another option is to create a new profile using the Profile Manager, create the accounts again and then migrate your e-mail, address books, filters, and other related files of mail of the old profile by this article.
  • slate of 21 has lost all the previous icons

    Until it is has about 2 weeks 21 slate worked perfectly with all icons app downloaded, displayed at startup.

    Now at the start of the slate is a large red and Brown arrow that occupies the entire half right side of the screen appears, but not all of the previous icons.

    Included in these missing icons is the Skype icon, which, once selected previously worked with great video.

    I tried to download Skype once again, but all I can install is "Skype to go.

    I think that this app is only for mobile phones.

    Skype has always works well on my XP desktop but does not recognize the web cam.

    That's why I bought the slate 21 to have Skype video calls on the big screen.

    Hello trouze,

    Sorry, but I can't say that I've never seen or heard of this before.  I don't think you could attach a screenshot of the issue on the forums.  Take a screenshot of just hold 'Volume -' and 'Power' buttons at the same time.

    Right now my only guess would be that you have downloaded an app that has replaced the homescreen on your device.  If this is true, you have 2 solutions:

    1. Return to the default home screen.  There are some instruction how to http://www.techrepublic.com/blog/smartphones/pro-tip-reset-your-android-home-screen-back-to-the-default/
    2. Reset the device by going to setting > backup and Reset and choosing Factory Data Reset.  This will return the unit by default, but it will also be possible to erase your data, please backup first.

    Again, this is only a guess at this point that I have never seen this personally.

    It will be useful.

    Kind regards

  • Windows 7 has lost all my settings and started looking for XP

    I have a new laptop with Windows 7 (64-bit). I'm about to install the software, I need for work and customize the settings. Everything worked up to now, when happened the following.

    -J' installed software (nothing special, for example (from a reliable source) existing communication software)

    -J' restarted the computer

    -All my settings for the taskbar and toolbar are lost (they disappear). The button (which is instead of the XP Start button) effectively changed to start button (looks like the XP Start button). The translucent window headers changed to those not translucent (as I'm used to XP). The bar of tasks/toolbar settings won't save any more (even if I register, they go back to an earlier version)

    How can I go back to 'Windows 7' and get my settings? What could have caused this strange behavior?

    I did this before on my own just see if I liked better. I did not so I went back to the Windows 7 look. In your case, there are a few different scenarios that can cause this.

    1. your theme has changed without your consent. -You can fix this with a right-click on your desktop and go to personalize . Change your theme to one that you have registered or by using the Windows 7 default labeled "Windows 7" theme. From there, you can simply add your images to customize your wallpaper.

    2. your Visual effect have been replaced by 'adjust for best results' .

    Open the menu 'Start' and right-click on computer . Go to Properties .

    Near the top-right corner of this window, you should see "advanced system settings" , click on it.

    Click the Advanced tab. Under performance , click settings .

    From here (depending on your graphics card), choose either ' let Windows choose what is best for my computer ' or ' Adjust to improve the appearance '.»» Click OK .

    3. Finally your graphics card driver.<->

    Is not as likely to happen by simply installing a program, but it's not of the unheard. Windows 7 will come back to that look older if somewhat your driver is corrupted and windows is still trying to allow you to use your computer. If you uninstall or damage your driver (ex installed a new graphics card) your computer can use graphics embedded gives you the possibility to use some of the nicer features of Windows 7 like the transparency and Aero Peek.

    Again, this is not as often, but if the other 2 suggestions above do not alleviate your problems try to reinstall your graphics card driver.

    http://www.nvidia.com/download/index5.aspx?lang=en-us-> for Nvidia

    If you are not sure of this graphic card you have click on your Start Menu , go to the search box and press Device Manager type enter. Click the arrow next to display adapters .

    A drop down menu should appear showing you graphics card. Go to one of the sites above to update or restore your drivers.

    The program froze, with the beach of rotation ball.

    I did a Force Quit, then tried to re - open LR. Received the following message:

    A search shows that all the photos are still in the users folders > pictures > Lightroom then in different folders and collections.

    How to get or create a catalog to post a link to the photos on my hard drive?  So far it seems no harm done, but the photos are inaccessible.

    Geoffrey Luck wrote:

    Increasingly more complicated! Add. OLD as suggested did not LR to open the catalog with pictures. Instead, he opened with a single picture, exactly what happened when I first got the accident and responded to a command prompt to open a different catalog. It seems LR keeps pointing to this 'new' catalogue, but why he has a picture in it, I can't explain.

    You must manually select the Lightroom 3 original catalog file:

    Menu item: file > open catalog

    Navigate to this folder and select the file to Lightroom Catalog.lrcat 3 .

    Geoffrey Luck wrote:

    As to the "edited copies", I checked some of these pictures in sub LR files that were last imported and worked on and found they were modified versions. I had been scanning negatives b & w 60 years of age, and from LR to PES 9 to repair, so I am sure that I look at the modified pictures. I knew that LR edition is non-destructive, but I don't know where the originals were stored.

    When you use 'Edit in PS' with 'apply changes to Lightroom"a new file is created with changes in LR & PS. That's what you see. The original files are always in the same place... not shake... not deleted... no written.

  • Last update of developer edition has lost all my favorites and addons

    I love Firefox! I use it exclusively. When I opened Aurora today (11.10.14) ALL my favorites and addons disappeared! Of course, I want back the way they were. How to achieve this?

    Hi rudeann, sorry to hear that you have problems with the bookmarks. My heart stops if I see ALL of my favorites have disappeared. Fortunately, we can fix that.

    I have an article in support of Firefox everything on here get these bookmarks. You have to take a look because what you do depends on how you put Firefox in place. It is if you use the normal Firefox and developer edition That's if you use just developer edition .

    Take a look at the article that fits your situation and let me know what happens. Hope you find your Favorites quick return. Let me know if you have any questions or this does not work for you.

  • Firefox has lost all the tabs and bookmarks on startup.

    Computer ran out of memory, I quit firefox because he did not like it usually does, and then when I restarted, all the Favorites have disappeared, the bookmarks bar is now empty and all the Add-ons have disappeared from the top of the browser, but not the background. However, all the Add-ons are still there, but not all work (e.g. further development of Reddit). I tried to restore the bookmarks or even import chrome, but this says it fails in the first case and terminates the process, but nothing happens in the second.

    What is going on? I really don't want to switch to chrome after using firefox for more than 5 years.
