Does not work Z930 satellite - black screen

Recently, there was a problem with my Z930 and I don't know if it's a damaged screen or if it's something to do with the software. I also use Windows 8 as the operating system.

Earlier today, the unit was functioning normally, but later it began flickering with a mess of pixels around like a small problem, with black lines rising from the bottom of the screen.

A few seconds after that cleared up, the whole screen is black.
It is still on, but there is that a screen white, black - I can't even see the cursor.

Every now and then the screen flickers as he struggles to continue working. I connected it to a different screen and its typical display showed on the other device, so I'll take a guess that it is a damaged screen.

Before starting to prepare getting a new screen or even a new device, is possible that it could be something other than a broken screen?

Because it's strange because I take great care on the screen because it is fragile at first, I didn't hit it or had fluid on-screen, so have break a coup like this is quite strange.

Hello

The symptoms described as flicker with a mess of sounds of pixels like a graphics card problem.
Also the fact that the same symptoms are visible on the 2nd screen, could confirm my assumption that would affect the GPU.

In the case where the internal screen would be defective, the external screen should work fine, but this isn't the case.

From my point of few the motherboard so that the GPU must be replaced for fox the problem but of course the laptop everything must be tested by a service engineer before starting to replace all parts.

    Nothings happening. I tried turning market and its still does not.
    I also tried to connect to my TV with an hdmi cable.

    Connect it to the TV and wait until Windows 7 is fully loaded (you will hear sound Win) than trying to use FN + F5 several times. It may happen on the TV Office. Be sure you use the right settings on the TV (HDMI port must be enabled on the right).

    F nothing helps I presume the display can be defective then contact the closest service Toshiba and let them check your laptop.

  • Scrolling does not work on Satellite Z30-A-1DJ

    Hello

    Summer on the internet trying to find an answer for my problem; How to make scrolling, pinching etc on my touchpad?

    Scrolling never works with this laptop (2 months) and up to now, even moving cursor was not reliable, since sometimes when starting the laptop touchpad was completely dead and has not reacted to what.

    Now there seems to be problems with it since I uninstalled the driver for the touchpad and restarted my computer, but still scroll does not work.

    Troubleshooting for this problem was no good.
    They all lead you to the first research of mouse in the start-> mouse-> advanced properties screen and from here you can adjust the parameters of mouse pad.

    I don't even have this tab on my laptop, while all the others are there (buttons, pointers, pointer, material options).

    How can I adjust the settings of touchpad on Satellite A-z30-1DJ?

    The characteristics mentioned touchpad should be accompanied by software as hardware.
    There are standards of touchpad different as Synaptics, Alps, but also momentum that support different features and different software.

    In the case where this software isn't installed or is not working, the touchpad to scroll as well as other features are not available.
    It could also be that tactile built-in module support no additional features.

    To my knowledge the Satellite A-Z30-1DJ should be equipped with an Alps Electric touchpad and this touch pad is different and does not support the same parameters as MOMENTUM or Synaptic touchpad.

    However, as you said, the additional parameters for touchpad Alps Electric are in
    Control Panel? mouse? last tab (Advanced)

    If you wish, you can try to install the driver for the Synaptics touchpad that has been released for other series of laptops as Portege Z10T-A

    I'm not very well if this Synaptics software would work correctly under the Alps touchpad m power but its definitely worth a try.

  • MicroSD does not work with Satellite click 10 LX0W

    Hi all

    I recently acquired a Satellite phone click on 10 LX0W Toshiba.
    The card says it's compatible with micro SD with UHS - I (maximum size: 128 GB)
    According to the SD Association, the Mode Bus UHS - I is compatible with the classes of speed UHS 1 and 3 (http://www.sdcard.org/consumers/speed/)
    However, the card, I bought (Kingston 64 GB, micro SD XC I, UHS speed class 3) does not work properly in this laptop but it works perfectly in other devices.
    The card is recognized by the Satellite click 10 but reading or writing is extremely slow and often give error messages. I can't even format it using this laptop.
    I think that there is something wrong with the Toshiba laptop, but can you give me your opinion please?

    Thank you!
    Kind regards

    Same thing here

    Can someone help me with this?

    Hello

    It is not easy to say what the problem is here. What you need to do is to activate the BT module correctly and software BT must start properly.
    Are you using the original operating system that you got with your laptop satellite? BT Stack (software) is installed on your machine?

  • Drive HARD Win 7 recovery does not work on Satellite L750

    Hello

    I have the Toshiba Satellite L750 with preinstaled win 7.

    I instaled the upgrade to win 8 (from dvd).

    After that I improve the MS site to Win 8.1 System.

    The system does not work properly (DVD is not recognized) so I have to install previuos system.

    First of all, I'm improving my BIOS for the new one - 3.60.

    After that I try to win 7 reinstal my HDD recovery (which is located on the d partition). But it does not work: it has been impossible to start recovering in the menu of the bios (F8 key does not work, it was only possible to press F2 or F12).

    So I have to install my dvd 8.0 Win and now I have it and it works. But this is only a clear system without any addons like nero, ms office etc.

    My question is how do reinstal win 7 of my hard drive recovery that I always on the d partition?
    in the bios the F8 key does not work.

    After clean OS installation installation of HARD drive recovery not working anymore. If you want to have the original image of recovery preinstalled on your machine, you must use recovery DVDs.
    I assume that you did not create this disc, right?

    In the user s manuals document clearly described how it works with the image recovery and the creation of recovery disks.

  • Audio driver does not work on Satellite U400-112 with Vista 64-bit Buss

    Hello

    I installed Win Vista Buss. 64-bit on my Toshiba Satellite U400-112 but the original driver for the Toshiba site does not work properly, honestly does not at all. The only driver that works is a winner. Vista driver but when I plugged in her headphones just got pregnant shape, but there is no sound in headphones.

    Can someone help me, please?

    Hello!

    I have a Satellite U400 with Windows Vista 64 bit also, and I used the driver on the Toshiba site (Conexant 4.36.7.0).
    It works without problems, I can hear sounds with the speakers and headphones.

    Maybe you have an old BIOS. After the installation of Windows Vista, I made an update of the BIOS so try that too.
    The BIOS you can find also on the Toshiba site.
