• Computer freezes on logging off the screen.

  Our computer required a restart of the system, we have followed all the instructions (computer restored last time it updated) & was able to connect and find our computer in a normal state.

  Then told us to restart. The computer is now frozen on the screen "logging off". What does that mean?

  Hello
  1. why the ' computer required a reboot of the system?
  2 have you made any changes to the computer before the show?
  3. you are working on a domain environment?
   
  Method 1:
  If you have external devices attached to the computer, I you recommend trying to disconnect and then try to shut down the computer.
  Method 2:
  Step 1:
  You can try to use the power button to turn off the computer and then try to start at startup and check if the problem persists:
  Some options, including the mode safe mode, start Windows in a limited State, where only the essential is started. If a problem doesn't reappear when you start in safe mode, you can eliminate the default settings and basic device drivers and services as a possible cause.
  Follow this link provided below to start your computer in safe mode.
  Startup options (including safe mode)
  http://Windows.Microsoft.com/en-us/Windows7/advanced-startup-options-including-safe-mode
  Step 2:
  If it works fine in safe mode, and then perform a clean boot.
  To help resolve the error and other messages, you can start Windows 7 by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

  How to solve the problem by running the clean boot in Windows Vista:

  Note: once you have completed troubleshooting, perform the steps in the step 7: to reset the computer as usual.
  Method 3:
  You can update the drivers and application software by visiting the manufacturer's Web site.

• How to restore the calculator application to drag it to the top of the screen to control

  Can how I restore the calculator to drag it to the top of the screen to control center? It seems to have been removed from the bottom row? Thank you

  Are - what you got to remove the calculator of your applications on the phone? You can find the calculator on the phone itself? If you find it, then try a reset. Hold down the home and sleep/wake together until you see the Apple logo and then release. The phone will restart. There are no settings to change what appears on the display. See if the reset solves your problem.

  EDIT: what exactly you see in the Control Center? If you see only controls the music, then drag to the right to see the rest of the access to the control center.

• I tried the clean boot and now the hard drive works simply and screen went black. The mouse still moves around the screen without any outher work keys? That is what it is?

  I tried the clean boot and now the hard drive works simply and screen went black. The mouse still moves around the screen without any outher work keys? That is what it is?

  Hello

  You will need to reverse the clean boot, as it is either incidental compared to
  the real cause of the problem. What, where you try to fix initially using the cleanboot?

  You can access Mode safe? Repeatedly press F8 as you start? If so you can try the configuration - control panel
  The Device Manager - graphics card - Double click on - driver tab - click the driver UPDATE - then
  Right click on the device and UNINSTALL - REBOOT.

  Another method to try to get to the desktop (try in normal Windows Mode without failure) is
  CTRL + ALT + DEL and the processes tab find EXPLORER.exe and COMPLETE the PROCESS on this subject - and then
  on the Applications tab - lower right - new task - type in EXPLORER.exe. Safe mode is reached
  by tapping F8 as you start several times.

  First check this thread in case it is simple and if not to come back to this thread.

  Black screen problems are extremely difficult to repair and all patch is usually on a base hit or miss.
  That there is no information on a black screen as it is on a blue screen just adds to the
  Difficulty. Often using a restore point or Startup Repair will have no effect. You can try a
  Google to see the proposed repairs, whom some have worked however these cover a wide
  field efforts.

  Here's a video of one of them.

• Satellite A100-998: brightness & DVD Hotkeys never worked again

  Brightness of the screen for my Satellite 2 years could easily be adjusted by the Fn + F6/F7 keys, but not this new. In addition, the keyboard Play/FF/Rewind for the DVD Player do not work.

  Toshiba Hotkey Utility shows a file 1.37 MB on my Add/Remove Programs list. A solution might be to delete and reinstall this program? If so, my recovery disks, such as provided by Toshiba, would allow me to re - install the Hotkey utility?

  Thank you very much for all your comments.

  Hello

  Sorry, but I can't believe that the brightness Hotkeys & DVD never worked again. With the settings everything should work well.

  Before starting any discussion can you please check your laptop model? A100 is fairly new and may not be 2 years old.
