  • BlackBerry Bold 9000 Blackberry Smartphones - could not load any software and unable to use the phone

    Hello

    I have a blackberry bold 9000 and has been updated from the last app on this subject yesterday. Due to the low battrey my laptop turns off until the software has been installed to prperly. I tried the following:

    (1) to take the battrey and turn on the phone and tried to load the software again but that doesn't seem to work because the software does not recognize my phone it says unknown device.

    (2) I tried to use the option of updating the Web site, but also, which doesn't seem to work

    The display shows the following message appears when turned on.

    The application's permissions:

    The driving security application tries to access the information from the phone. I can't move the trackball on the appropriate option.

    Not really sure if there is a way to solve this problem.

    Help will be very appreciated. Thanks in advance.

    Concerning

    Ashish

    (1) make sure that you have Blackberry Desktop Manager installed.
    http://NA.BlackBerry.com/eng/services/desktop/
    (2) on your PC, go to start > run and copy and paste the following line exactly (i.e. with quotation marks):

    'c:\program files\common research in motion\apploader\loader.exe' /nojvm

    (3) the Application Loader Wizard will appear - click on "next".
    (4) in the ' connection: ' drop-down menu, you should see "USB - PIN: UNKNOWN". Click on the button "next".
    (5) you should see a list of applications ready to be installed for your Blackberry. Press Next and finish, and that you are well on your way to get your Blackberry to life.

    Just unplug and let the process finish completely.

    NOTE: If you do not display the list of applications mentioned in step 5 and instead to see the message "the Blackberry Desktop Software has no Blackberry Device Software for the device you have connected to the computer. Contact your wireless service provider or system administrator', then you must download the Blackberry operating system for your support and your device.
    http://www.BlackBerryFAQ.com/index.php/BlackBerry_Operating_System_Downloads
    Just select the appropriate type of carrier and network, select your Blackberry model from the list and download the latest version. Install this download and follow the steps above again and you should be on the right track.

  • Cannot use Windows + space and unable to see the language bar.

    Yesterday, I just did a full system recovery (at the original factory image). on my new laptop Dell which has windows 8.
    I had two languages in my preferences of Arabic and English
    Basically, the problem is that I can't use the shortcut Windows + space to change the language. everything works just Alt + Shift
    Also, this is not the language next to the clock bar! The taskbar looks like this

    and when I activate the indicator of "entry" system icons:
     
    It appears only as an empty space between the clock and the sound!

    also when I press Windows + I
    There is no language next to the power icon icon!

    Everything worked perfectly after recovery, but just after the execution of windows updates, he disappeared.
    I tried to remove Arabic and leaving only English alone and then add it back. but did not work
    also tried to change the settings here:

    also here

    but nothing has worked.
    so I restored all default settings and they don't currently exist in the two photos above.

    I already reinstalled the operating system!
    in any case, I did what you mentioned and did not work.
    Thank you.

  • Unable to limit the display of the window reduced to Thunderbird

    Until a few weeks ago, I could reduce the window of Thunderbird to complete only half of my screen from left to right. Now, it will only minimize to about 2/3 of my screen. When I drag the edge to a closer position he goes only so far and stops. I don't know why suddenly this change happened. Is there a way to make the reduced window narrower Thunderbird? I use Windows 7 Professional Version and Thunderbird version 24.4.

    Is still there, the problem in safe mode? Hold Shift (Option: Mac) when you start TB.

  • Satellite Pro M70-113: cannot install Vista graphics driver and lines appears on the display

    Hello

    I have satellite pro m70-113 with ati x 700 graphics card.

    When I installed vista, he installed the default drivers for the x 700 'mobility radeon x 700-microsft Corp.-WDDM '.

    I've updated the display drivers for vista, that released by toshiba 2 days back... but the driver is not updated to the latest version, only the catalyst control center is installed when I ran the update of the driver of toshiba.

    The problem is that whenever I put my laptop in standby or hibernation and resume... the screen shows thin lines vertical/horizontal... and I can't use the laptop... and I have to still put the system to sleep, just to hope that it is not blocking the screen this time...

    This problem is 25% of the time only when resume...

    This problem is not resolved by the update driver for toshiba has released a few days back... as is not installs the drivers (I can't even install the drivers with the option "update drivers" of Device Manager and select file driver update from toshiba.) It says windows find new driver, but could not install the driver... Contact the manufacturer...)

    This snap shows the problem... : http://img360.imageshack.us/img360/2783/12042007366copyod1.jpg

    I updated the driver from an earlier version of catalyst, as it is downloaded from the ati site before that toshiba has released the update... this time it updates some 8. XXX version but the screen problem remains...

    Second, this update of the driver leaves me not sleep my system... the process starts for a sleep, but go back to the locked screen without making sleep ever... so I have no choice to get stuck with the default Windows... drivers having only the problem of the screen... and not the problem of sleep...

    Anyone here with a solution?

    Thank you.

    Hello

    I have Satellite M70-159 and I noticed the same thing several times. For most Vista works well but I don't remember cases in which the described problem occurs. I was just curious on M70 Vista and have had no time to intensive testing.

    Anyway, it will be interesting to know if you have already updated the BIOS to the latest version 5.10. If this is not the case to do this and watch carefully if the problem persists.
