  • Re-install Windows 8 pro on PC, how many times before that the product key is not valid?

    Due to problems with Windows Update, and more specifically by using the 8.1 free update, I had some problems and have re-isntalled twice now on this PC.

    You install previous motherboard no re-day after the first installation.

    First install on the replacement motherboard activated via telephone due to the new material.

    2 more reinstall without a phone on the same PC.

    The general consensus is that, once you get to the installation of 5th Activation of the phone is necessary.

    How many times before that the product key is not valid?

    I only ask that the errors are related to data that is not stored on my PC.  and given that Windows 8 is nowhere near the performance and stabilty before I used the App store update I have to reinstall until it's resolved.

    Required to reactivate by phone after the 5th reinstalled only happen based on the license.

    If you make significant changes with a license pre-installed as a motherboard, then you will not be able to use the phone or Internet activation.

  • Is it possible to have iMessage turned off automatically when the phone detects that it is not connected to wifi?

    My daughter continues to send iMessages when she's out and about (IE. When it is not connected to wifi) and iMessages are sent using its data allocation, and it continues to go over its data allocation. Is it possible to get the phone to turn off the iMessages automatically when it detects that it is not connected to wifi, so that messages are then sent via sms texts, and then it reconnects to iMessage when reconnected to the Wifi? (I know it can be done manually in the settings, but she keeps forgetting to do so).

    Not automatically.

  • Satellite Pro L550 - 13 M - screen turns off several times


    Strangely the portable above turned several times its screen off several times. The lights are all on, but the screen goes completely dead. During the restart, the screen is OK for about 10 minutes, then it turns off again! We rebooted several times and its been over and over again. I started in safe mode and check the latest updates AV etc, which are updated. There have not been recent software additions.
    We are now back up things just in case!

    Can anyone help with what this might be?

    Thank you!

    Best way to check this problem needs to connect to an external monitor. If you notice the same behavior on external monitor it seems to be an internal hardware or software problem. Otherwise it of just the internal monitor that is faulty.

    You did changes to the computer before the show?

    Method 1

    Step 1: I suggest to start in safe mode with network and check if the problem persists:

    Note: select Safe mode with network.

    Step 2: If the question does not persist in SafeMode with network, then put the computer to boot and check what third-party application's driver is causing the problem:

    Note: after a repair, be sure to configure the computer to start as usual as mentioned in step 7 in the above article.

    Method 2: Run the Microsoft safety scanner to ensure that the system is free of infection by the virus:

    Method 3: Try the suggestions in the link and check if it helps:

    This should ask in the answers – Windows Forums for your version of Windows.

    Check the cable at both ends. Try the monitor on another computer because it could be the monitor.

    The issue could be the video card in order to check with the system manufacturer (manufacturer of motherboard for custom
    systems) or if actual video card manufacturer a separate device.

    If there is a separate video card you may need to remove ALL power and then remove and reinstall
    the map - in fact, remove and replace - do not just tight.

    The video driver may need to check updated and then re-installed with sources of support above.

    I hope this helps.
