Imac suddenly shut down and will not connect to internet

Hi, my imac running snow leapord was working fine. Then when I came to it a couple hours after using it it was shut down. When I restarted it would not connect safari or google chrome to internet. However, some websites it could access. All the login websites can still be used. My internet connection is good, I have another computer running on same modem and it works fine and internet provider has checked out the connection and it is good.
Error message - server has unexpectadly dropped the connection.

    I was charging and updating my mini ipad last night when it suddenly shut down and will not turn on since then. What do I do to turn it on again?

    Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased.

  • HT1766 My iPhone 4S suddenly shut down and will not come back on.  Does anyone have an answer for this problem?

    My iPhone shut down and will not come back on. Can anyone give me an answer on how to correct this problem?

    Connect to a wall outlet so you have solid power, then do a reboot by holding both the power and home buttons until the apple logo appears, ignore the red slider if that appears.

  • X220 Sudden shut down and will not turn back on

    I have a Thinkpad X220 Tablet. It has worked fine the last 1.5 years. It recently shut down suddenly, no shutting down screen or warning, just straight to black. The battery was full and it was plugged in. It will not turn on and when plugged in with the AC adapter no lights come on. I have no idea how to go about fixing this or what could be causing this. Any advice would be greatly appreciated. 

    Hi Zevain,
    Welcome to Lenovo Community Forums!
    I’m sorry to hear that your Lenovo ThinkPad X220T is not powering on.
    I would suggest you to perform Flee Power – remove the battery and any other peripheral device connected to the computer. Hold the power button for 10-15 seconds and then connect only the AC Adapter and try to turn ON the computer.
    Swap the battery and AC adapter with a good known one if you can to check if it’s a battery/adapter failure. Take out the memory, start the system and check if you hear beep sounds.
    Please let me know the happenings!
    Best regards,
    Mithun.

    my iphone shut down and will not turn on.  how do i get it to turn on?

    Connect iPhone to Wall Charger for 10 minutes it may turn ON itself. If still OFF, keep on charger and Reset, hold both home and power buttons for about 20 seconds until the iPhone begins to start.

  • Help! While editing a photo in CS3 the program shut down and will not reopen my psd file.

    Help! While editing a photo in CS3 the program shut down and will not reopen my psd file. The error message reads "cannot complete your request because of a program error" -- it is a very large file (I have been saving it all along) and I had just "flattened layers" and went to open up a new, blank photo file when it shut down. Is there anyway to get this file to open? Any advice would be greatly appreciated! (p.s. after reading a couple of similar threads, I have a feeling it's hopeless. But I'd also like to know WHY this might have happened!) Thanks in advance!

    Thank you. I appreciate you taking the time to respond and for sharing the article--I did panic. Here are the details of my system:
    Model: HP p7-1247c
    Processor: AMD A8-3820 APU with Radeon HD Graphics
    Installed Memory: 8 GB (7.48 usable)
    System Type: 64-bit
    Windows 7 Home Premium
    I am using Photoshop CS3. It seems that I can work on photos and save them. But I am unable to open them back up. I have tried saving the files as psd and tiff with the same result. The error message is:  "cannot complete your request because of a program error"
    The interesting thing is that I can open up InDesign and "place" the psd file within InDesign (then export and save as a jpeg). So I don't think the files are necessarily corrupted. I uninstalled Photoshop and reinstalled it last night, but there's no change.
    If you have any ideas, I'd appreciate it. Or, should I repost my question with this more complete info? Thank you!

  • My Ipad2 just shuts down and will not turn on. Rebooting does not help. He switched on when I start charging it. In this case, the battery is charged.

    My Ipad2 just shuts down and will not turn on. Rebooting does not help. He switched on when I start charging it. In this case, the battery is charged.

    Standard troubleshooting steps in the following order:
    1. Reset: Press the sleep/wake button & home button at the same time, keep pressing until you see the apple logo, then release. Ignore the slide to power off.
    If no change, continue:
    2. Restore your phone from a backup, note: if the problem is related to corrupt data, while this will restore a fresh OS, it will also restore the problem.
    If no change, continue:
    3. Restore as a "new" phone in itunes & re-sync your content. All saved data will be lost.
    If no change, make an appointment at an Apple store.

  • HT1222 I started the lastest iPhone 5s software update then my phone just shut down and will not turn back on. I've tried the home button, the button plus the top right button together for 20 sec, plug it in and nothing

    I started the lastest iPhone 5s software update then my phone just shut down and will not turn back on. I've tried the home button, the button plus the top right button together for 20 sec, plug it in and nothing

    Plug your device into the original charger & block in a wall outlet and leave it alone for a couple of hours. Then, while it is still plugged in, restart it by holding down the home button and the power button for 10-15 seconds until you see the Apple, then let go.

  • My IBOOK has shut down, and will not start back up

    ok here is what has happened. yesterday my 1.2ghz g4 ibook started randomly shutting down. it would shut down and it would take a while of me pushing the power button to get it to start back up. when it would come on, it would switch between charging and not charged quite rapidly even though my power cord was in. now however, it has shut down and will not start up. the battery is fully charged. anyone have any ideas?

    I'm telling you. I have lost all faith with Apple. The old iBook I had, 800MHz G4, simply worked fine with no problem waking up or starting up, although it's just a bit slow. Now, I am super frustrated when it just couldn't wake up, either with the sleep light flashing or not, ie it's black screen initially and when I press the Power button once to get it back to life, it just stays black!!!
    So the only thing to do is to force power down by pressing the Power button for 10 seconds. Then I press the Power button once to start up, but it just stays black screen. I've left my iBook in that state for a day now, hoping that it will come back alife. But no! And the worst is, I had a similar problem starting up from wake just the day before. I called the Help Desk and they advised me step by step, from taking out the battery, to pressing OptionsCommand+PR, and OptionsCommand+OC, and doing Apple Hardware Test. The iBook seems to just work fine while on the phone with them. And barely 3 hours later, the thing just couldn't wake up. I've powered down and up many times now, and I've left it powering up, but still black screen till now (one day already).
    Finding out about resetting PMU on the support page, I've also tried that, but it still can't work.
    And you know what? I've sent this unit for repair 3 times already! First they say it's the HDD problem, so they changed that. Then when it still happened, they say it's the logic board problem, so they changed that for me. And again when it happened, they changed another logic board for me. So now, it's the fourth time, what do you think I should do? I don't think going back changing another logic board will help!
    I am in fact ****** off! If Macs are great, then why me? Why my iBook? I am telling this forum that we cannot accept a big corporation giving us sub-standard products. I've since read this forum carefully and found that many of us faced the same problem! We just cannot sit down idly and let the company get away with it. This is a warning to fellow users out there that face this same problem. Let us voice out our frustrations and make Apple give us some compensation for it. I say this because I depend on my laptop iBook for presentation to clients, and this happened exactly twice when I was in front of my clients. I don't mind losing face but can Apple compensate me for my loss of business and future business from my clients?
    Voice out strongly your unhappiness to Apple now!

  • My iphone suddenly shut down  and  it not trun on  what  is the  problem?, my iphone suddenly shut down  and  it not trun on  what  is the  problem?

    hi
    i don't  know  why  my  i phone suddenly shut down and  not  be  on at all
    may u  halp  me ?

    Assuming that the battery isn't empty (and it can take 10 to 15 minutes of charging before it will respond), then have you tried a reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds, after which the Apple logo should appear - you won't lose any content, it's the equivalent of a reboot.
