Satellite Pro 440cdx - how can I change the brightness or contrast

My screen is weak and hard to see objects on the screen, any advice will be more welcome.many thanks for any help.



The brightness of the display can be changed by pressing the FN or FN + F6, F7 key combination.
The contrast could not be changed on the screens of laptops that it is set automatically.

But if it of very difficult to see anything on the screen, then an FL inverter may default.
The fl inverter is a small part that controls the brightness of the display.
Maybe it s need to be replaced.

    How can I chance the A10 coastal boot?
    With ESC, I can access the BIOS, but I can't chance anything except the time.

    Thank you


    I think you should check the BIOS again because as far as I know, there you can change the boot priority.
    In addition, you should find more options in the BIOS as only the Date and time.

    Check it!

    The CURIOUS reader is fixed with a screw at the bottom of the unit. Then, turn the computer over and remove one screw an optical disk drive.
    The second screw is hidden under the keyboard. That's why this screw must be removed also. And then disconnect you should be able to pull-out of the optical drive.

  • How can I adjust the brightness and contrast of an object that is part of a vector?

    I have edited one (text & symbols of color, brightness, contrast, etc.) file, generated from its original file, LOGO.eps LOGO.tif, . Now, I am trying to edit the EPS to match the TIFF. I got regarding the extraction of the color of the text in the TIFF file and applying it to the text in the EPS file. My problem is that I can not change the brightness and contrast of the symbol in the logo. Is it possible to adjust the brightness and contrast of an object that is part of a vector? I need make a darker symbol and I tried change > change colors > saturate and adjusting the intensity to 100, but it does not darken. And I can't really spend extra money on plug-ins like Phantasm cs. Help, please.

    I may be as simple as adding a transparent overlay with some gradients.

    It can be incredibly complex and be better done in photoshop.

    even a clipped sample can help.

  • Satellite P300D-220: How can I change the Toshiba Multimedia Buttos config


    How can I change the options for the buttons to support key Toshiba?

    I want to change the button to 'cut the computer', in 'turn led light on or off.
    Toshiba Button support shows only two possibilities: CD/DVD and in German "Your aus" what means "mute".

    What it means?

    In Vista was the button with the right option, now I have installed Windows 7 Ultimate x 86. Since then the mute only it.

    I hope you understand my question.

    This two threads did not help me, because I find no "utility control" in the list of the drivers for my computer.


    Win 7 is different!
    The configuration of keys on Toshiba utility is not available for Win 7!
    After the installation of the VAP (value added package) for Win 7, you can configure the keys by pressing the button for the first time.

    I did it on my laptop after changing from Vista to Windows 7.
    I pressed a button and the window a pop-up asking me which application should be attributed to this button.

    As far as I know after the configuration it of not possible to change this once again

    Maybe after the new TPC facility you could configure the new buttons

    Have you tried to update the display on your laptop driver? Check the Toshiba site for an update: decision-making supported Downloads & => Download drivers

    In addition, it would be interesting to know if you are running the factory settings or you have installed your own version of Windows?
    And what operating system are you using? Have you installed all Windows updates?

    For external LCD, monitors, you must set the screen refresh rate of 60 Hz.
    And if you want to change the resolution of the screen, you must select the second monitor in the graphics options on Windows.

  • Satellite Pro 6000 - how can I update the BIOS?

    Hi all

    I have the problem that my laptop does not start 9 of 10 times with the message: * block 1 BIOS is damaged, call your service man.

    I want to update BIOS but for the Satellite Pro 6000 I can only find an update the BIOS from Windows. But my laptop does not start! Rarely the machine starts, but when I try to update the BIOS, I get the message that I already have the latest version of the BIOS

    My questions:
    * Is there a BIOS update file that is a BIOS floppy? (for example the Satellite Pro 6100 has 2 BIOS files, 1 Windows and 1 making a floppy disk)
    * Is it possible to update the BIOS with the same version of Windows?

    Or perhaps there is another solution for this problem? Has no need to update my BIOS?

    Thank you.



    I agree with Luke.
    The rom Bios module seems to be damage.
    Either it must be replaced or flashed again.

    But you won't be able to do that! The update of the Bios on the Toshiba page focuses on winning and you will not be able to update if the windows are not running.

    You last chance is an ASP that could check the BIOS ROM.
    As I said, most high, maybe new reflash module Rom help but cela can be answered simply by an ASP technician who checked this.
