EOS 7D will not come on when a fresh rechargeable battery is installed and switch turned to on

A real Canon brand battery and a real Canon brand charger?If not it may be a faulty cheap battery and/or charger.  If it is, your 7D might need service.

"One is located on the memory card door (a tiny tab on the door engages the switch hidden in the edge of the door-frame.)" It has been a while since I sold my last 7D but I don't think this will stop the 7D from powering on.  The door being closed or open or even no CF card will not stop it. On the other hand the battery door switch will. ...I do still have my 7D's, and Ernie is wrong. If either door is open, the camera will not turn on. (But he's right that a CF card need not be present.) Sorry, Ernie!

    Thank you I tried the reset again did not fix- I think I am down to calling Apple and paying for a tech - phone company says it is a software problem.  I just updated to 8.1.3  - I thought the update might fix it.

  • HT1338 MacBook Pro 13.3: Desktop screen will not come up when turned on.  Screen is blank except for an icon of a folder with a question mark on it, in the middle of an otherwise blank screen, laptop making a clicking noise.

    My MacBook Pro 13.3 MAC OS  X v10.7 laptop will not come up.  Blank screen comes up, no color/desktop, etc., only an icon of a folder in the middle of the screen with a question mark on the folder.  Laptop making a clicking noise. Suggestions? Thanks!

    It's under warranty. Take it in to have Apple fix it.
    The "flashing ?" means the machine can't find the start up disk. The clicking noise is a give away that the drive is damaged.

  • I accidently dropped my iphone from about 15 feet in the air, had an otterbox gel case on it but phone will not come on, I can still hear the voice controls and will play music randomly by pushing the center bush on phone any clues on how to get phone wor

    I recently dropped my iphone 4 from about 15 feet in the air, had an otter box gel case on it and it did not break the screen, but it will not come on, no back light but can still hear the voice contorl and randomly hear music when I push the center button, I have it password locked but can't see to unlock, any help out there

    Just guessing here, but dropping your phone is probably the reason your screen or backlight doesn't work.
    Only solution I see is to take it to Apple and buy and out of warranty iphone 4.

  • My Iphone 4 battery will not charge, only when I no level battery

    Hey, like the title.
    My Iphone 4 will not charge, only when the battery is totally dead.

    Hello, DrSmith_01. 
    Thank you for visiting Apple Support Communities.
    I would make sure you are using an Apple branded cable with your iPhone.  If you are, the troubleshooting steps in the article below may help.

  • My Reminders app will not open. When I try to open it, quits and gives me an error message: "Reminders quit unexpectedly while using the CalDAV plug-in." My Reminders is synced with my iPod touch, and it is fine on that. How do I fix it?

    Also, the Calendar is loading very very slowly, and sometimes it quits and gives me the same error message as above.

    The problem has been fixed with the most recent OS X software update.

  • Installed 7.0 on computer yesterday, will not come on when I clock on

    I installed the update for Firefox yesterday and now when I click on it to go to Firefox, clicking twice, the arrow & hour glass disappear and nothing happens. When I updated yesterday, it asked me a question about the apps or something on my computer and I may have answered when I didn't want to but I cannot get to the internet using Firefox now. What can I do?

    Not sure what the problem is, but you may have temporary dificulty getting firefox 7 back again, IF it is not already installed.
    (Updates from Firefox 6 to firefox 7 were apparently [https://support.mozilla.com/en-US/forums/contributors/707670#post-42774 suspended] yesterday. It appears an update probably firefox 7.1 is being released to correct a problem with it loosing some extension updates as it updated firefox in some instances. )
    What exactly is your current problem
    * is it that firefox will open but not connect to the internet ?
    * one problem is security software or firewals not recognising the new software, they may need resetting see also

  • Hotsync Manager will not come up when I double click on Hotsync - device will not Hotsync

    I have a Windows 7 64 bit PC and am trying to hotsync using USB to a MEZ1000 Palm device from Aceeca.  I am using their 64 bit driver for the USB.  I installed Palm Desktop 6.2 and the Acceca 64 bit driver about 4 months ago and it was working fine.  A few days ago I tried to hotsync and it wouldn't.  Tried rebooting PC and uninstalling and reinstalling the Palm desktop and Aceeca driver.  I have done that 2 - 3 times following the clean uninstall instructions that I found on this forum.  The install hangs when it tries to configure the registry.  I can see the hotsync.exe process in the task manager.  The install will not proceed past this point unless I end the process in the Task Manager.  Also, in searching the PC for anything named hotsync, I found a file called Report.wer that was dated 04/02/12 (the day I first tried to hotsync and failed) in C:\Users\ADMIN\AppData\Local\Microsoft\Windows\WER\ReportArchive\Critical_Hotsync.exe_599940f2117296adef2f8cf88fb71dd13d49811c_453e7b5c

    Post relates to: HP TouchPad (WiFi)

    Okay - I got preview back - it seems to have gotten hung and corrupted, so I went to library and fixed the permissions there
    Click on "Go" in the Finder menu bar while holding down ⌘ key     and you will see Library appear in the pull-down menu, click on it and it     will take you to the "Library Folder".
    Hit the ⌘I keys, to get to pull up the “Get Info” window on the     “Library Folder”.
    Unlock the pad lock in the lower right hand corner.
    Click on the + symbol to add a user.
    When prompt add the 'root user'.
    Give the root user Read/Write privileges.
    Lock the pad lock and open Preview.
    But that wasn't enough so I went back to disk repair and even though I had just run it , this tim it fixed a slew of permissions problems -
    I then restarted and viola - I was able to use Preview again.
    Computer is running a little fast too.
    Thank you everyone..

  • How can i get my iphone 4 back up after it went dead. It had plenty of power, and it will not come up even after i hold down the home and power buttons for 30 seconds.

    My iphone 4 went dead even when there was plenty of batery life. I ran through the reboot for holding down the home button with the power button and it still did not come back up. Any thoughts?

    Plug it into a wall outlet for at least 30 minutes, then try resetting it again. If no respose, you most likely have a hardware issue. Make an appointment at an Apple store.

  • My iphone will not power on - when plugged in the battery will display, but it does not charge

    My iphone ran out of battery a few days ago, and now it will not charge back up. Its been plugged in for over a day, when the home button is pressed it displays a battery with 3 small red bars. I was able to get it into recovery mode and restore factory settings - but this did not solve the problem! it is still not turning on. I have tried changing chargers etc. already and i believe it is a problem with the phone. please help!

    Could be a battery problem. You'll have to visit an Authorized Apple Service Provider to Apple Store to get it checked for hardware issues.

  • My webcam will not come on when I am using a usb port for my mic.

    I have recently started having an issue with my isight not coming on if there is an agregate audio device plugged in, such as my usb presonus, I would like to be able to simultaneously Record in GarageBand or other recording software while recording video imovie. This used to work fine  So I'm not sure if I changed a setting or what happened.  Please help me with this issue. 

    That unfortunately did not help. Is there any more info I can give to help you understand whats going on?
    I have an Audiobox 44vsl that plugs into a USB port to be used as a mic/ instrument interface with my MacBook Pro.
    When I open Garageband or Presonus Audio software I can record and all that but if i try to simultaneously use iSight such as in iMovie or Skype it doesn't even turn the camera on (no green light) but if I unplug the Audiobox it works fine. I used to be able to do this just fine but just recently it stopped working.

    You may have to let the battery fully drain
    Try:
    - iOS: Not responding or does not turn on
    - Also try DFU mode after try recovery mode
    How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • IPhoto (and Aperture) will not start up when iCloud is activated.  Programme stalls and have to force quit.  If iCloud sharing and streaming deactivated, programmes load OK

    IPhoto started locking up on loading having worked fine previously.  If I disable iCloud streaming and sharing programme starts up with no problem and works perfectly.  If I attempt to start iPhoto with streaming/sharing active the programme locks but if I then disable sharing and streaming it will then continue to load.  There are no other iCloud problems with other programmes as far as I can see.

    Try this fix discovered by User photosb189:
    From Finder, hold down the option key on your keyboard and click on the Go menu at the top of the screen
    Select Library from the drop down menu
    Then navigate to Application Support > iLifeAssetManagement > assets
    Right click on the 'sub' folder and choose Compress
    Drag the resulting zip file to your Desktop (as a backup)
    Go to your System Preferences and choose iCloud
    Turn OFF the iCloud Photos option
    Go back to Library > Application Support and DELETE the iLifeAssetManagement folder
    Now, in System Preferences, turn the iCloud Photos option ON
    iPhoto should now be able to launch. Give it enough time to re-download your Photo Stream content. if you are missing any of your My Photo Stream photos (more than 30 days old), unzip the sub folder on your desktop and drag that into iPhoto.
    Back up first, of course.
