Will a hard reboot reset the IMAC after a potential power incident

I have had a lighting incident and 2 items on the surge protector did not repower up.  One is the cable modem which had to be replaced.  The IMAC will not start up.  Is there a way to reset the IMAC so that it powers up?

I concur with Rudegar. If you took enough of a lightning strike to permanently knock out the cable mondem, it was probably enough to permently knock out the iMac also.

  • Why does my iPhone 5 take very grainy flash photographs in the dark will a hard reboot be safe to do to try to fix or is it a hardware issue?

    Why does my iPhone 5 take very grainy flash photographs in the dark will a hard reboot be safe to do to try to fix or is it a hardware issue?
    And By hard boot I mean holding the home and power button down at the same time for 10 seconds or whatever
    I see other people have these grainy flash photographs if you try to take a picture in darkness the picture comes out very dark and grainy I thought the software would ultimately fix this but it's been going on for over a year I usually take my photographs in daylight but I need this to be fixed
    If it is a hardware issue I hope Apple will replace my iPhone 5 because I was just waiting for one of the iOS updates to fix it I bought my phone in November 2012 its the iPhone 5
    Please help or advise if you can was this just a software or hardware issue I know Apple was aware of it but I was advised that iOS update would fix it but obviously not
    Is it safe to do a hard boot on my iPhone five by holding the power and home button at the same time for 10 or 20 seconds I saw someone said that fixed there's at least temporarily
    I'm typing this on my iPhone five right now why do the words go off to the left and right no matter if I hold the phone vertical or horizontal the words bleed off to left right so for me to proofread it I have to move my text left to right to proof read it
    Thank you

    The flash on a smartphone camera is tiny. It only lights up a very small area right in front of the camera. It won't light up the whole scene.
    Have you seen the size of the flash on a professional camera? Even they can't light a whole scene in the dark.
    Fact is, a smartphone camera is not capable of taking good photos in the dark, even with the flash.
    You'll need to buy and learn how to use a professional, dedicated SLR camera to be able to take good photos in the dark. It is not easy.

  • Have been advised by my email provider (recently blocked account requiring password reset) that they will only reset the password after a proven anti viru and malware scan has been done on ipad and iphone. Is this necessary and if so what do i use

    Have been advised by my email provider (recently blocked account requiring password reset) that they will only reset the password after a proven anti virus and malware scan has been done on ipad and iphone. Is this necessary and if so what do i use

    As KP has pointed out, there actually aren't any anti-virus programs in the App Store. There are a few that allow you to scan e-mail or stuff like that, and a few that provide you with information about malware and new threats for other systems. But none are available that can scan your iOS device for malware, because the security restrictions in iOS do not permit any apps to have that kind of access to anything. Which means that you also cannot be infected with a virus (unless you have jailbroken your device).
    If your account got compromised, that had nothing whatsoever to do with your iPad. Someone simply hacked it remotely. Happens all the time. It's really amazing that, in this day and age, e-mail providers are so ignorant of technology and how their own systems get compromised that they would try to require you to run software that does not exist!

  • The back button no longer works. I have disabled all add-ons, rebooted & reset the defaults for the browser and nothing has changed. This happens on all webpages.How do I get the back button to light up again?

    the back button no longer works. I have disabled all add-ons,rebooted & reset the defaults for the browser and nothing has changed. This happens on all webpages.How do I get the back button to light up again?

    Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
    *Don't make any changes on the Safe mode start window.
    *https://support.mozilla.com/kb/Safe+Mode
    If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
    *Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
    * Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
    Another possible cause is a problem with the file places.sqlite that stores the bookmarks and the history.

  • Possible to attach external Esata hard disk on the Imac Quadcore 27?

    Is it possible to attach external Esata hard disk on the Imac Quadcore 27? Or any other Imac? The purpose is for video editing, but maybe Firewire 800 is good enough for hd video in Final Cut Pro?

    Hi Simen,
    The iMac series do not have an ESATA connection and there isn't a way to make a connection inside. The only possible way is to perform surgery on the iMac which
    1. probably will not work and
    2. almost for sure Invalidate the warranty
    This is a fairly common questions however there just isn't a way to do it. If your external drive also has a Firewire or Firewire 800 connection that is your best bet. As you probably know your iMac has a Firewire 800 port and you can daisy chain Firewire devices.
    Regards,
    Roger

  • What does it mean on itunes when it says a movie will not be available on the cloud after purchase?

    what does it mean on itunes when it says a movie will not be available on the cloud after purchase?

    It means that you get only one download of the movie per purchase, so once it's downloaded, you'd be wise to make a backup. Otherwise, if something happens to delete the movie, you'll have to buy it again.
    Regards.

    There is nothing you can do. That is the Activation Lock that Apple has implemented tout down on theft of their iPhones.
    Most likely the iPhone is stolen.
    It is totally worthless to you.

  • Wary about upgrading my wife's 3gs from ios4 to ios6. will the data associated with an app be lost or will it be restored from the backup after the upgrade completes. There is no way to export, email or even print the data contained in the app

    wary about upgrading my wife's 3gs from ios4 to ios6. will the data associated with an app be lost or will it be restored from the backup after the upgrade completes. There is no way to export, email or even print the data contained in the app so I am concerned

    If the backup and restore takes place properly, you shouldn't have any issue as millions of people have done an update from iOS 4.

    Help help please... I'm running Photoshop CS, on a Windows XP machine.   After re-booting the machine after an unexpected power failure I have been told that the "Configuration appears to have changed since the time this product was activated. To continue using this product I must re-activate it".  BUT the activation link informs me that they no longer support the product (neither online nor telephonically).  So how can I re-activate this software?

  • What hard drive does the iMac use ?

    I have a 17 inch iMac with intel Core Duo with 80GB hard drive. The screen is damaged because of vertical lines and i am replacing it myself and i thought it would be a good idea to upgrade the hard drive while i am at it.
    Am i correct in assuming that the hard drive is a SATA 2.5" laptop drive ?
    I found a cheap Hitachi 200GB 2.5 inch 3 gb/sec 5400 RPM, 8MB Cache, 12MS SATA II drive. Is this suitable ?
    Will any 2.5 inch SATA drive, be it SATA, SATA II, SATA III etc. work fine ?

    Are you sure, the 17" Early Core Duo iMac's came with a 160GB Hard Drive.
    see > iMac (Early 2006) - Technical Specifications
    No, the 17" Early Core Duo iMac uses a 3.5 SATA Drive.
    Personally I have upgraded the Hard Drive in several Early Core Duo's using both 320GB and 500GB WD Cavair Blue's.

  • How can I wipe my imac hard drive if the imac is not recognising my keyboard

    I fell into the same trap many others have with installing Windows via bootcamp &amp; not setting up the hard drive formatting properly. So I've got a "Disk error. Press any key to restart message."
    I've tried pressing command to get it to boot into OS and using 'c' to get it to boot from the OS cd. But my mouse and keyboard are not being recognised so these don't work.
    I'm thinking that there must be a way to wipe the hard drive so I can reinstall OS. I thought it may work to connect it to another computer in target disk mode, but the iMac won't recognise me pressing T. Would anyone know whether there is any other way I can wipe the hard drive or otherwise get OS back running?

    If your keyboard is a wireless one, wait until the startup chimes sound and then immediately press the appropriate key.
    If your keyboard is a non-Apple one, then startup commands may not be embedded. In this case, using an Apple keyboard should work, such as the original one that came with the machine.
    The key to hold down to bring up Startup Manager during booting is the Option key, not the Command key.

  • Will it cause reboot to the server.

    Hi All,
    In one of our production server, currently we have default setting to the SQL Server memory 2147483647, and the version is Microsoft SQL Server 2008 R2 (SP1) - 10.50.2500.0 (X64) Jun 17 2011 00:54:03 Copyright (c) Microsoft Corporation Standard
    Edition (64-bit) on Windows NT 6.1 <X64> (Build 7600.
     Customer wants it to set 4.5 GB as mar memory to SQL, Now my question is " when we set it max memory required by customer,  will this(setting Max memory) cause a reboot to the server or have any significant chance of causing a problem
    since this is production server?
    Thanks.

  • Want to reset the Imac - Can't Login using Leopard

    I just got a brand new 24" Imac and upgraded it to Leopard following a transfer of all the files from my old imac. Then all problems started as I could not login as it does not recognise any password incl the admin one. I tried everything mentioned in the forums and decided to give up as I have all the info back-ed up.
    someone knows what I need to do to reset/re-install all software again as nothing would have happened and start all over again with the Imac.
    Thanks

    thanks
