Satellite L750 - display of the bands of questions

In the last two days, my screen suddenly started degraded bands like reading to a depth of less than normal color. There is serious of bands in dark areas of the screen and low color values are clipping.

I tried to re - install Nvidia drivers, change the display profiles, change the depth of color and the management of colors without success.

If anyone has any experience with this problem and can help, I'll be very grateful.

Hello

Is there a possibility to test the GPU functionality and an external monitor? Just to see if everything is OK on the external display.

Did you notice the same problem when you start the laptop in SafeMode (F8 at startup)?

  • Satellite L750 charging and the question of the random stop

    Hi all

    Recently I had problems with my laptop Satellite load.

    The laptop is running Win7 64 bit and is a Satellite L750 PSK2YA - 0LN028

    Now the problem is not that his load not but that he chooses to charge and no fees when he wants to. With the laptop plugged into current alternative to a real charger Toshiba (3.96 tested A 19.48V) the laptop charge for a minute or so normally with the animated icon (moving) in the set by saying "plugged in, load. Then all of a sudden the animation stops in the status bar, but it still says "plugged in, charging" 2 lights on the front of the laptop flashes orange simultaniusly (power and battery NOT AC led) and the computer will decide to drain itself of the battery, then stop without warning (with connected AC).

    This will happen under simple highload AND webbrowsing. My dough said Toshiba PC health integrated program is 'good' and that CPU Temp is not more 70% and the fan works as it should. When I remove and reconnect the AC adapter it will stop blinking and start to load for a minute and then start all over again.

    I tried to remove and reinstall the battery Module controller via Device Manager and Reset BIOS by disconnecting all power and hold for 30 seconds, these two methods do not fix my problem.

    The computer still works on AC if the battery is removed and the only devices I plugged in a USB mouse that is NOT plugged into the slot of the USB3.

    Any help would be greatly appreciated or if someone knows what that flashing lights twin mean on a table of errors, or something (because I can't find the online error codes). It's my first laptop and I bought this one thinking that I could do most of my stuff a desk would be, but it's just been a nightmare...

    Thanks in advance, if you need more info let me know.

  • Re: Satellite L750 - advanced of the mouse settings do not work correctly

    Satellite L750 model (one month). The problem is that whenever I have start the computer, does the point of the mouse synaptics device, but retains the advanced settings that pressing on with three fingers, turn to turn, or you can use the wheel to move up and down the page. The funny thing is that is activated by clicking on the mouse icon in the control panel. Once I have access to the icon, the mouse works perfectly and is displayed in the toolbar.

    In device management, tells me that works perfectly and that the driver is up-to-date.
    Everyone thinks of any solution? Thank you

    Hello

    To be honest, I put t really understand what you're talking about.
    Do you have problems with the USB mouse or the touchpad?
    This device is not working properly: mouse or touchpad?

    The series L750 supports a touchpad with additional feature called gesture (multi-touch).
    Here you can find nice description on Synaptics how it works page.
    http://www.Synaptics.com/solutions/technology/touchpad

    In addition the parameters could be found in Control Panel-> mouse-> Advanced tab

    FYI: you can disable and enable the touchpad function by pressing the small button above the surface of the touchpad (POWER).

  • Satellite L750 - to change the input Mic and Line In

    Hi, I have a Toshiba Satellite L750 running Window 7. I have a small studio in which I have a mixer connected to a drum kit.

    On my old Toshiba Satellite C660, when I plugged it to the output of the mixer to the microphone, a pop box port up appeared asking me what I had just plugged.
    I chose Line In and everything was fine

    With the L750, I get no such box and the computer just treats it as a microphone, as it compresses everything from the port.

    I tried the Smart Audio installed in the control panel and it does nothing. Is there anywhere that I can choose the socket is treated as Line In, no microphone.

    Getting boring now!

    Thank you

    > On my old Toshiba Satellite C660, when I plugged it to the output of the mixer to the microphone, a pop box port up appeared asking me what I had just plugged.

    Yes, but the Satellite C660 was equipped with a microphone / lin in the port.
    Are you sure that your L750 supports a combi jack mic / lin in?

    You can find the description in the user manual.

  • Satellite L750 - stuck on the Realtek card reader

    Hello

    I just got a Toshiba Satellite L750 / 00K and I turned it on for the first time. He asked about the recovery and I chose 64-bit, and then on the settings in the box. It restarted once then I left it to charge. I came back and he was stuck on the Realtek card reader. It has been like this for maybe 2 hours, I can move the mouse but nothing has changed. He said that commissioning could take some time but I don't know if something is wrong. Help, please!

    Thank you

    Hey Buddy,

    Installation of recovery can take a very long time. In your case I'd wait a bit more.

    If it helps doesn t you should try to start installing recovery again. You can do this if you access Windows Advanced Boot menu and select Repair my computer.

    Missing a very important information: preinstalled OS the original that you have with your laptop or you have installed a clean version of Windows?

    When you buy the new book it comes with factory settings. If long your laptop has this plant, you will be able to install the recovery image according to instructions with F8 at startup. If you change something that it will no longer work (install own os, partition structure).

    In this case you must use the created recovery disc but I assume you didn't create one although it is clearly described in the document s user manuals.

    Problem is that you can't do much. Either it works or not. If there is no way to install image recovery I'm afraid you need to order the new Mr. recovery disk you can do it on https://backupmedia.toshiba.eu/landing.aspx

  • The mouse does not work on my new Satellite L750/L755

    Hello world

    I bought a toshiba Satellite L750/L755 but the mouse does not work, I have no control on it that if I use an external mouse, while I have put pressure on the touchpad.
    I tried the following options:
    I updated the driver - I changed the operating system

    but nothing, still the same problem. Next laptop will be a Mac for sure.

    I look forward to hear from you

    Daniele

    Hello Daniele

    It's really strange that the touchpad does not work even if you have installed the right driver and installed the operating system again. At the first moment, we can say there is probably a hardware problem, but please be sure touchpad is listed in the Device Manager and also active correctly (FN keys).

    Check it please all the properties of the mouse.

    My laptop (Toshiba Satellite L750) comes from the usual turn on, I tried removing the battery and the charger then hold the power button, remove the battery and the charger, keeping the battery but no charger, but all without success.

    Ideas?

    EH... it is not easy to say what the problem is, but probably power electronic is a troublemaker.
    When you connect power AC is one of the power LEDs ON?

  • Re: Several questions about the recovery of the Satellite L750 features

    I have several questions about the recovery of Satellite L750 features available to it. Any help and answers would be useful.

    (1) when I started the laptop first, he asked me to create a recovery CD incase I need to reinstall the operating system. But he also said that he built in the recovery partition, so therefore, I have to make a recovery cd or not?

    (2) will be the recovery CD is exactly the same as the recovery on the system partition?

    (3) is the partion of CD or recovery includes all the integrated software pre-installed with the laptop?

    (4) also in the device manage management it shows watch partion recovery but it is empty, is it true?

    (5) in the second partition (drive D) system, he has a record with what looks like the recovery of files and folders. Is it safe to move/remove it?

    Hello

    I'll try to provide answers:
    1 - to ensure that everything works perfectly you don t need these discs, but if something goes wrong with the HARD drive you will not be able to do anything. When you have the recovery DVDs, you will still be able to install the recovery image and once again the factory settings. So my advice to you is: create these discs as soon as possible. Use only on DVD-R media and buy products of high quality (TDK or Verbatim).
    2 - Yes.
    3 - Yes.
    4 - No. Don t be confused with this.
    5. in a first time create restore DVD, and later you can do what you want. I put t know which files mean you but don t touch anything before that of the recovery disks to be created.

    In the past, many people have been experimenting with the structure of HARD drive and partitions and later was surprised when installing disk recovery HARD has been damaged. Don t make the same mistake.

    If you have any other questions you are welcome.

  • Satellite L750-A114 - display does not

    Hello world

    So sad story, I bought a Toshiba satellite series notebook PC (L750 A114) 20th day of the month last through digital LLC Dubai. I gave the maximum care for the last 20 days. Sentence might have used for 10 hours.

    Yesterday, I started to do something and closed the screen and kept in the mode 'sleep' (I hope that it goes into sleep mode while closing the screen).
    Orange light on the far left at the front of the laptop was that I guess.

    Thought he was in the mode.then sleep later in the night after 3-4 hours I opened the laptop and you press the power button once to turn on the laptop, but instead of this, he went off.then do not think to put it on again.

    In the morning when I tried to turn on the laptop, it starts, but no display is coming.lights on the keyboard are all about. Can someone help me please on this?.

    I am so depressed thinking about the money I spent for this and works that I let go because I don't have another pc or laptop with me.

    Laptop specifications are:
    TOSHIBA SATELLITE L750 A114
    I7 2670QM D 6 750 15.6 BT 2 G WC W7HP white

    Thank you very much in advance.

    Hello

    Try this:
    The laptop must be turned off.
    And remove the AC adapter and the battery.
    Now press power 30 sec long and wait a bit.

    This support allows you to get the laptop working again?

    I have already created a new system image on the recovery partition and a system repair disc.

    Supermalx.

    > can you tell me how to use the recovery discs to recover
    The question is what you want to recover? The whole machine or only the missing files?
    In any case, a partial recovery is not possible, all you can do is complete recovery image installation.

    After the installation of portable full recovery you will have factory settings again, only in this case, you will be able to use without any problem recovery disc creator.

    If you still have some questions you are welcome.
