I've had a power cut and now cannot turn the mac back on! Any ideas most welcome.

Try the following: 
Make sure the plug is secured on the back of your iMac.

    I have an old (first generation) iMac that I still use sometimes for the applications that are on it. I was using it yesterday and unfortunately had a power cut. I went to turn it on today, and nothing at all happens. It's as though no power is getting to it. I've checked the obvious things, changed the fuse, tried different cables, poked paperclips in reset holes, but nothing doing. I wonder if there is anyone who knows what might be wrong. I was hoping to get some of its content transferred soon, but I'm guessing that can't be done if it can't be started up. Many thanks, if you can help

    Hello,
    >It's as though no power is getting to it.
    Would it be correct to assume that no sounds at all can be heard? Also, no lights, not even green or amber at the power button?
    >unfortunately had a power cut.
    Was it possibly a power cut in connection with a thunderstorm? Any other evidence of higher than normal voltages (light bulbs, et cetera)? Has the line voltage been checked (measured with an appropriate voltmeter/multimeter)?
    If necessary, it would be possible to remove the hard drive, and then connect it to an external IDE/ATA to USB adapter (example below). That way you could gain access to files on the hard disk from another computer.

  • I changed companies and had icloud with my old company - now i want to just use my personal id and can't change any icloud info to match my personal ipad id - i can't delete the icloud without the old company id and password which is not available to me

    i changed companies and had icloud with my old company - now i want to just use my personal id and can't change any icloud info to match my personal ipad id - i can't delete the icloud without the old company id and password which is not available to me - it probably doesn't even exist anymore!
    Because I can't delete the icloud account, I keep getting view terms to accept and it wants to go to the old company account.  I can't do anything to get rid of this - when I try to delete the icloud it wants me to delete find my ipad and asks for the old co. id and password - it's a vicious circle and i just want to get rid of it and start fresh with my regular personal email id and password!!!  Help!

    You will need that old Apple ID and password, which does indeed still exist. Apple doesn't delete Apple IDs, though if this ID was in the control of your company they may have changed the password. If so, you will need your former company to log into the iCloud account using that ID and password and erase the iPad or remove it from iCloud:
    http://support.apple.com/kb/TS4515?viewlocale=en_US
    Until that's done you cannot change those settings, and if you try to restore the iPad will have it locked with Activation Lock and thereafter be unusable.
    Regars.

  • I have had my ipad for 6 months. We had a power failure and ever since my ipad will not charge with the wall adapter that came with it.  It will SLOWLY charge when plugged into computer port. Can anyone help me resolve this?

    I have had my iPad for 6 months.  We recently had a power outage and my iPad was plugged in with the adapter that came with it.  Since then I can not charge iPad with adapter, however I can charge it SLOWLY on my computer.  Do you think the adapter got fried?  Also do you HAVE to have iTunes with an iPad, they were charging me alot of fees for games I did not download NOR give my password to have them downloaded so I cancelled iTunes because fo too many fees. Could this have anyting to do with the battery not charging?

    Since then I can not charge iPad with adapter, however I can charge it SLOWLY on my computer. 
    Well, something's definitely wrong if it won't charge from a wall outlet. Make an appointment at a Genius Bar or take it to an Apple certified repair provider.
    As for iTunes charges, according to Apple  iTunes Store: All Sales Are Final

  • I was in Lightroom and had a power surge and now Lightroom will not launch....what can I do to fix it?

    I was in Lightroom and had a power surge and now Lightroom will not launch. It encountered an error when reading from its preview cache and needs to quit. Lightroom will attempt to fix the next time it launches. I have shut my system down and Lightroom still will not launch. Does anyone have any suggestions?

    delete your preview cache (.lrdata folder).
    Here has location:

  • My Mac Book Pro has just had a new memory and solid state drive installed. After the installation, the Lightroom tools all became grey. There is no longer any color on the screen other than my picture. Even the color sliders are grey.  Can you please help

    My MacBook Pro just had a new memory and solid state drive installed. Since the installation, the Lightroom tools are now all grey. Even the color sliders are grey. Please help!

    My guess is that your operating system got updated to Mavericks and that you are running an old version of Lightroom:
    Sliders are white, look different | Mac OS X 10.9 Mavericks
    Be aware of a Lightroom bug with color management in mavericks that makes shadows too deep in the Develop module: Jao's photo blog: Serious color management bug in Mac OS 10.9 "Mavericks" and Jao's photo blog: Further quantification of the Mavericks color management problem.

  • Has there been trouble with the charger.  I am getting to re-order but the one i had the had the power surge and the end was blackened.  Not sure if it safe to use the laptop again?

    Has there been any trouble with the charger?  I am getting ready to re-order but the one i had.... the had the power surge and the end was blackened.  Not sure if it safe to use the laptop again?  Thanks.

    Can you also see blackening in the power jack on the PowerBook? If so, I would be worried that the surge also damaged the computer/
    Does the computer run OK on just the battery? If it is working on battery power, that limits the number of things inside the computer that could have been fried.
    If the computer is severely damaged by the surge, it's not worth repairing. However, a couple of posters in Apple forums said their homeowners'/renters' insurance paid them replacement value of their computer after power surge damage due to known problems on the grid, like the huge power outage that hit the SW Untied Stats and part of Mexico yesterday.

  • Power cut and now freeze mid start-up

    Help, help, help!!!
    I had a power cut today and my mac obviously turned off!! When I try to re-start it it comes up with the apple pic and starting Mac OS X window and then goes to a blue screen and freezes. I have booted off the install disc and that worked - I ran disk utility / first aid and it came back with no problems on the hard disk. I haven't got enough room on the hard disk to re-install OS X (Im running 10.4.6 if that is relevant)??
    Does anyone have any suggestions of what else I can try? I really need my beloved mac to be up and running!!!
    Many thanks in advance

    Power hits can do crazy things to machines. It looks like you're stuck with trying out various things to see if they are the problem. So...
    1) Try pulling out all the RAM sticks but one (maybe a RAM stick got smoked).
    2) Try removing all external peripherals except for the mouse and keyboard.
    3) Try seeing if all your fans are running (cracking the case open before you turn on the machine can help). Some freezes happen due to overheating.

  • Power Cut and HomeHub3

    Hi all,
    Had a Power Cut last night, well about 20 of then within an hour, and they have caused the Home Hub3 to do an automatic Factory Reset.
    This morning I noticed that it had done a Factory Reset as all the passwords and setting had changed.
    I also noticed that WPS has been enabled again aswell as the BTFone SSIDs being changed back to BTOpenzone-H and BTFON from BTWifi and BTWifi-with-Fon.
    Is this an update or just caused by the factory reset?
    Cheers

    ah ok, so it was unlikely that the generator even started as it was very short bursts of inturrupted power.
    haha all equipped then, We've just got an old corded BT 400 Decor phone when the cordless ones have no power and lots of torches 
    Would the homehub be ok apart from factory resetting it's self or could it also corrupt the firmware? All seems ok at the moment, just weird how it's enabled WPS again and changed the BTFon back to BTOpenzone-H, thought that thoses settings would be coded into the firmware and not actually user-changeable settings.
    cheers

  • I just bought a power adapter and it is not working, says "not charging".   The same for the mobile charger.   Anything I need to do in the setting?

    The device is locked to the carrier it was purchased through unless you specifically purchased it as unlocked directly from Apple.
    Only the carrier to whom it is locked can authorize it's unlocking.  To do so, the user much contact them to start the unlock process.

    What type of encryption are you using with your wireless network -WEP or WPA?
    If your wireless router supports both which it should unless it is quite old and you are using WEP, try switching to WPA which is much more secure than WEP which is important if you have a Windows PC or any Windows based device connected to your network.
    In addition, when was the last time you checked Netgear's website to see if there is a firmware update available for your wireless router model that you haven't installed?

    You could go hunting for a fair price on a refurbished or restored Intel-based Mac or MacBook, as most early models of CoreDuo and Core2Duo can run Snow Leopard 10.6.8, and some much more recent.
    The Apple Store's Special Deals section that is online has some fairly recent examples of hardware with an OS, original accessories as noted, power cord, and complementary one year coverage. Eligibility for extended AppleCare plans are noted & may be available for various items in the store. Subject to availability. Refurbished. Like new. The price difference can be about the same as the additional two year AppleCare plan may cost, so get that too.
    Third party repaired restored or available through other channels vary in quality, quantity, condition, and may be lacking in some or most original accessories; they should include basic hardware as originally equipped and have the boot-install software disc set as intended for that build model & year specification, included.
    Auction sites rarely have that much of a kit together, w/ missing discs, scruffy, extra fees, etc. On the other hand, companies that restore and repair Macs for a living and are authorized Apple service centers may have something, if you aren't in the market for something holiday new or really quick. Older models if reasonably refurbished can still shine years later.
    Hopefully this helps somewhat.
    Good luck & happy computing!

  • Just downloaded adobe XI trial and can not convert pdf to word, says trial is period over

    just downloaded adobe XI trial and can not convert pdf to word, says trial is period over. what can i do

    For some reason this seems to happen to some. It may be that you have a date issue on the machine and Acrobat noted it. By the way, Adobe is the name of the company, not a product.
    I have no idea how Adobe sets and tracks the trial information. It may be there is something else that has caused an issue and Acrobat thinks you have already had the trial on the system and uninstalled it. As far as I know, there is nothing you can do. You might be able to check with sales to see if there is a work-around, but users can do nothing to help you.
    Sorry, hope you can find a way to test the product. It might also be related to the version of Windows that you did not state.
