Wifi won't turn on after os update today

Did the update this morning and can't turn wifi on

Hi John,
Thanks for the additional information.  What I would try next is resetting System Management Controller:
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer. 
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

If this still doesn't help, it would be time to take it in to be looked at.  You can setup an appointment at a Genius Bar by clicking on the following link:

  • HT1222 iPhone 5s won't turn on after this update. Battery was at 98%, tried holding sleep & home button while plugged in, no good. Any ideas?

    iPhone 5s won't turn on after this update. Battery was at 98%, tried holding sleep & home button while plugged in, no good. Any ideas?

    P.S. I just noticed; when I hold the power and home button at the same time while it's plugged in as if I was going to restart it, my computer acts as if I'd plugged it in again (it makes the USB notification sound, itunes opens up again, I get the same "your iphone is in recovery mode" message, etc.), but that's the only response I've been able to get from pressing anything on the iphone. thanks again.

    iphone 5s won't turn on after downloaded recent update

    Hey lillyluv2010!
    Here is an article for you that will help you troubleshoot this issue:
    iPhone: Hardware troubleshooting
    http://support.apple.com/kb/ts2802
    Will not turn on, will not turn on unless connected to power, or unexpected power off
    Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
    Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
    Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
    After at least 30 minutes, if:
    The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
    The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
    Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
    If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
    If the display turns on, go to step 4.
    If the display remains black, go to next step.
    Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
    If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

  • Help! Phone won't turn on after ICS update

    So I just updated my phone a few hours ago. I looked down at it to see if it was finished and noticed it was off. When I tried to turn it on it wouldn't power up. I've had it on the charger for an hour now. When it goes on the charger, the red Motorola insignia comes on the screen but nothing happens after that. My phone may have died during the upgrade so that could be the problem. I've reset it about 10 times and it still won't turn on. Any suggestions???? I had a baby a month ago and would be devastated if I lost my pictures.

    Jess i can tell Ya is Hook your Razr up to the Charger and Leave it on there for about 3 Hours Maybe 4 and then with the Charger Hooked to it Try to Restart it.. if you Can See were your at on the Download it Takes about 15 Minutes for the Initial Download then the Phone Will Power itself but should Come Back on and Finish the Rest of you Will see the Little Android Character And Below it A Rectangle box and you should see another Bar in Yellow moving across it. When that's Finished Give it some Time and it Reboot itself and then Update you Apps then it should Finished After That.. But hopefully By leaving it on the Charger for a While Will pull it out of the State it's in Now..

  • IPhone5S won't turn on after software update

    iPhone5S is bricked after software update.  Apparently this is becoming widespread.  Hello, Apple??????  http://www.techienews.co.uk/976861/apple-ios-7-0-6-update-allegedly-bricks-iphon e-5s-ipad-air/  http://www.thebitbag.com/iphone-5s-and-ipad-air-bricked-by-apple-ios-7-0-6-updat e/70286

    Hey Stheus3,
    Thanks for the question, I understand how frustrating this may be. It sounds like the update process may have been interrupted, and to resolve the issue, we’ll need to restore your device in recovery mode with iTunes:

  • IPhone won't turn on after software update

    Last night I went to update my iPhone 4S to the latest iOS 7. I went to sleep while it was updating and it was charging and when I woke up it wasn't on and it kept vibrating every few seconds when it was charging. I tried to turn it on, then I tried to restart it and held the home and sleep buttons for 20 seconds. I tried connecting it to iTunes and iTunes won't detect a device. Any help??

    I tried to restart it and held the home and sleep buttons for 20 seconds.
    Try it this way ...
    Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, then swipe the slider to power off.
    Then press and hold the Sleep/Wake button until the Apple logo appears.

  • Laptop won't turn on after BIOS update

    A few days ago, my 9470m Ultrabook automatically updated its BIOS. This was fine, as it has updated its BIOS before in the past. I went to do some things while it updated, and when I came back, the laptop had turned off. The charge light (the lightning bolt light on the edge of the laptop) was blinking white and amber and did not turn on when I pressed the power button. When I took off the battery, the light stopped blinking, and when I put the battery back in, the light began to blink again, but the laptop still would not turn back on when I pressed the power button. I've tried taking off the battery and plugging in the AC only, but still the light would just blink and the laptop would not turn on when I pressed the power button. I do not know what is wrong. The laptop had been working flawlessly until the BIOS update. Any help would be appreciated.
    Thanks to any support.

    Hi,
    At first, please try a Hard Reset as follows.
    Performing a hard reset
    Disconnect all peripheral devices and remove all USB devices and SD media cards.
    Disconnect the AC power adapter, remove the battery and then press and hold the power button for at least 15 seconds to drain all residual power and restore default startup settings.
    Reconnect the AC power adapter (but do not insert the battery), press the Power button, look for glowing Light Emitting Diodes (LEDs) near the caps lock and num lock keys, and listen for sounds of a fan or other moving parts turning.
    If the computer starts normally after performing a hard reset, you are done troubleshooting.
    When the Notebook restarts keep tapping the f10 key to enter the bios menu.  Press f5 to load the defaults (this is sometimes f9, but the menu at the bottom will show the correct key), use the arrow keys to select 'Yes' and hit enter.  Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.
    I am waiting to hear back from you.

  • E71 won't turn on after marketplace update

    Hi,
    My phone does not boot anymore. When I try to turn it on I can feel the vibration and see the keyboard and display light. However, the screen remains blank. Not even the Nokia logo comes up. After a minute or so the phone turns off again.
    This all happens after OVI marketplace update. I was going to the application folder and it said I had to load a marketplace update to proceed. I did that and the installation seemed to be successful. It then asked to restart. I confirmed and boom...now my phone is deard.
    Please please help me. I tried to do a hard reset (3 + * + green + on) without success. When I connect the phone to my computer, the nokia suite does not recognize it anymore. What can I do?
    Thanks

    Remove the battery for about 10 minutes, remove the memory card, try the 3 finger reset again. If that doesn't work you've to bring your E71 in for servicing.

  • Computer won't turn on after Software Updates

    About a month ago my computer had some Windows Updates, I installed them as per usual, it asked to restart the computer, but once it shut down, it wouldn't turn back on. I tried a few different outlets, no change (all of these outlets work). I left it unplugged overnight (8-10 hours) and when I plugged it in the following morning, it turned on and was fine until this past weekend.
    Again, there were more updates, this time it was for AVG and when it went to restart, it again wouldn't turn on. I tried the same thing, and it's not coming on. The light by the power button will flash when I push the button, real quick, but nothing. The light in the back shows power going to it.  I believe my computer is in the HP All-in-One 200 family, but I'm not sure which one (and though I've registered it, it doesn't tell me on my account which one I have, or I just can't find it).
    Is the motherboard done, maybe the RAM, or the HDD? I don't have the money to get a new computer at the moment so I really want to try and get a few more years out of this one (I have had it for 5 years). Any thoughts would be appreciated. Thanks.

  • My phone(4) won't turn on after latest update

    I ran the latest update last night & now can't turn on my phone. All I get is the iTunes emblem & a picture of the plug in on a charger. any suggestions besides a reboot. Don't think I've ever backed up my phone.

    If you get that screen then your iPad is in recovery mode.
    You will have to restore it on a computer using iTunes:

  • Blackberry Z10 won't turn on after software update. Black screen and LED light blinking

    Im using BB Z10 (stl-100-1 ) os version 10.3.1 for 9 months, recent days it hangs a lot and  it hanged later  not turning on and red led has been blinking simultanously. please help me

    Hi and Welcome to the Community!
    Please try this sequence...note that, throughout the entire 4h15m process, your BB must remain directly connected to a known-good wall charger (not PC USB, not a cradle):
    With the battery inside, connect your BB to the wall charger
    Leave it alone for 2 hours, no matter what the LED or the display does
    Remove the battery
    Wait 15 minutes
    Insert the battery
    Wait another 2 hours, no matter what the LED or the display does
    This has been known to "kick start" some BBs. If it fails, please do it again but increase the step 4 wait time to 2 hours, and perhaps as long as 4-5 hours.
    It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:
    Obtain an known good and already fully charged additional battery...use it in your BB and see what happens
    Obtain access to a known good and identical BB...use your battery in it and see what happens
    The results of this will indicate if it's your BB or your battery that has the problem. Note carefully please that "new" and "know good" are not necessarily the same things. While rare, a "new" battery certainly could be defective. Rather, the simplest (and least costly, btw) method to conduct this test is to find someone with an identical BB who has no issues...trade batteries and see what happens.
    Good luck and let us know!
