  • My IPhone is frozen on the lock screen, and will not restart or respond to ITunes. What do I do?

    I really need help. It's not functioning at all. It's frozen on the home screen, will not respond to Itunes, or its charger, it wont turn off, no matter how many times you hold down the Lock button. What do I do?

    Try a reset: Hold the home and power buttons at the same time until the Apple boot logo appears. No data will be lost.

  • How to repair "No bootable device insert disk and press any key" problem?

    I was browsing sites using Google Chrome when all of a sudden, my laptop completely turned off. I turned the power back on only to find the error message "Intel UNDI, PXE-2.1 (build 082)" appear in white letters, followed by a bunch of other error messages, ending with, "No bootable device insert disk and press any key". Whenever I try restarting my laptop, the same error messages show up.
    I've been reading about Toshiba laptops, to try to remedy this issue, and I've learned that as of 2007, Toshiba discontinued the recovery disks that had always accompanied the laptops, and instead, allow you to totally restore your computer without the help of a disk. (The model of my laptop is Satellite L300D - 01P).
    Now, apparently to restore a Toshiba laptop, you're supposed to press the '0' key while also pressing the power button, but when I do this, there is a beeping noise (which is apparently supposed to happen), but the error messages (ending with "No bootable device insert disk and press any key") still show up. Other than the affirmative beeping noise, no changes occur.
    Anyone had this problem or have any suggestions of how to fix it?
    Thanks so much.

    Have you also learned that you SHOULD create recovery DVD using preinstalled Toshiba recovery disc creator tool? When something goes wrong with HDD you can use this disc for operating system installation. This is clearly described in Users manuals document.
    Back to your problem:
    I don't know for sure but Im afraid you have some problem with HDD controller or HDD itself.
    Is HDD recognized in BIOS settings (F2 at start up)?

  • "no bootable devices" insert disk and press any key

    hi i just bought leopard yesterday AND I LOVE IT!! The only problem is after waking up i went over to my macbook and turned it one but the message: no bootable devices insert disk and press any key.
    came up i rebooted 3 times but i keeps coming up. so i decided to select the mac hard drive by holding alt when i boot it up that worked! but i still want it to be able to boot up straight away by pressing the on button. Also i deleted my boot camp partition yesterday could this be the problem?
    Many thanks in advance.

    Hi,
    in OSX open System Preferences (from the Apple Menu) go to Startup Volume choose your OSX Volume and do the needed restart.
    Should boot right into it.

    Leave it in the rice for at least a day and change the rice every other day or so. The rice and iPod should be in a sealed container.

  • I am having problem with my notifications bar and control centre bar. It doesn't work with sliding my fingers on the screen and when I restart the phone it works properly  but again after few days the problem persist? My phone is an iphone6 8.1.3

    notification bar and control centre not working by sliding on the screen and when u restart it works fine for 4-5 days then again the problem persists

    First, try to reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again. You will not lose data by resetting.
    If this does not help, set it up as new device, explained here:
    How to erase your iOS device and then set it up as a new device or restore it from backups
    If still no luck, get it checked by visiting an Authorized Apple Service Provider or contact Apple Support to get it serviced:

  • My ipod 5th generation is frozen on the lock screen and i tried restarting it 4 times and it continued to get stuck what do i do

    My iPod 5th generation is stuck on the lock screen and I tried restarting it 4 times and it continues to get stuck on the lock screen. What do I do.

    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.
    - Try another cable                                                       
    - Try on another computer                                                       
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
