Satellite P750 PSAY3A: Intel GPU switches do not to NVidia GT540M

I have a Satellite P750 PSAY3A 0MQ001.
I can't make Gpu Intel HD 3000 to the Gpu Nvidia Gt540M via the NVidia Control Panel (switching Optimus is not do properly either).

I choose the settings to use the Nvidia card high performance for some programs, but do not use them, it goes the same for games. The strange thing is, if I install the latest Nvidia 301,42 drivers via a facility clean, said programs will use the NVidia card, if I restart the laptop, they use the card NVidia still once, until I re - install the NVidia drivers again.

I tried to install the latest drivers Intel HD 3000, but the system said their inconsistent and I must use the Intel from Toshiba driver (I am sure I have the latest downloaded correct drivers).

I did a factory restore today that having the same problem, the Nvidia card is not used even if it is enabled by default, until I have go through reinstalling driver routine.

I am at a loss to know what to do. I talked to Toshiba support on the phone I have the warranty, but I want to make sure it's a "hardware problem" not "Software", before sending it to the sea.

I saw a message somewhere in my "trip of suffocation of the parameters" that says something along the lines of my Intel GPU must be plugged into a housing PCI Express x 16 for maximum performance, I know that the NVidia card is via looking through the Information when setting up Bus system, it's PCI Express x 16 Gen2 Perhaps the two Gpu need to be plugged into the PCI Express connector to move seamlessly between the two (I couldn't find the Info Bus for the Gpu from Intel), if so, this maybe the fault of hardware. I haven't looked, I don't want to void my warranty, but if that were the case, I would be willing to send it to get it looked at by Toshiba.

Can someone please give me some advice on forcing Intel to switch to Nvidia, as it is supposed to without having to constantly re - install drivers NVidia Lol...

Usually, you should be able to install the latest driver from Intel HD graphics card, but you must do so via Device Manager. You must choose the graphics card Intel and point to the folder of the Intel driver that you have downloaded from the Intel page manually.

    You must use the page of the Toshiba driver graphics driver because this driver is designed for mobile use. Drivers from other sources are not changed and lead to overheating GPU. This may damage your laptop.

    Hello

    I agree with resident.
    The Wlan switch on the side of the laptop has all the drivers and it works independently of the installed software!

    The FN + F8 key combination that allows the WLan should work on if install you value added package.

    You should also check if the WLan card is set on IT in Device Manager-> properties-> Advanced tab WLan card.

  • Satellite P750 PSAY3E: Win 8 Eco Utility will not install

    Hello

    ICH just tried to install the eco from the following site utility

    It's the right laptop and I installed Windows 8 Pro 64 Bit.
    Whenever I try to install the eco utility, the installation process says that the operating system is not supported.

    And another question: using WIndows 7, I had to install a driver in order to use the full cpu performance. Without the driver, the windows experience index has rated CPU with 6.9 Points system, with the pilot 7.4 points. As I installed most of the drivers available for WIndows 8 - including value added package - I think the eco utility must be the driver to ensure the performance gain.

    Could someone tell me if I'm right with this quess?

  • Satellite L500 14 X - Fan switches do not properly under Fedora 12

    Hello people,
    I seem to have the same kind of problems with the fans of speed on my recently purchased Toshiba Satellite L500 14 X and Fedora 12
    The fan turns slowly until the processor gets 37 degrees. Then it runs at maximum speed, and never slowed until the reboot.

    I updated the BIOS to 1.60

    Now, in the Ubuntu 9.10 on the same notebook it WORKS CORRECTLY. When the CPU is hot on 37 or more senior degrees it starts to spin faster and when CPU back to 34 degrees, the fan slows down and works almost noiselessly!

    I tried all the options of the kernel: acpi.power_nocheck = 1, acpi = off, acpi_osi = 'Windows 2006', and so on — nothing has really changed.
    I tried different Fedora kernels, include 2.6.32 - nope...
    I tried to find a reason why it works under Ubuntu and does not work in Fedora 12... But have yet to find something fishy... And I think that the problem is somewhere in the kernel.
    The main difference I see is that on fedora 12 I can not install the proprietary ATI driver, who normally installs on Ubuntu 9.10. It is because of the xorg version in Fedora 12 and seems that we must wait for the next version of the ATI drivers.

    One last thing - in Fedora 12 notebook became hot very quickly and without reasons of course.
    In Ubuntu, it's not so fast and requires CPU load with something serious.

    I don't want Fedora to Ubuntu, just because of this problem of FAN (nothing personal :))) so I need to get this working in Fedora 12)

    Maybe someone faced the same thing?
    Any help much appreciated! :)

    Hey!

    I found the solution. Incredible, but the index is ATI owner driver. As I mentioned previously, the Fedora 12 version of the ati 9.11 driver cannot be installed due to the latest version of xorg.
    I reinstalled my toshiba with Fedora 11, install the driver from ati.com ATI and here us are :) now fans are working properly!

  • Satellite Pro A200: Intel GPU - screen rotated 180 degrees

    My laptop screen went backwards!
    I tried CTRL - SHIFT - R to put right, but I don't have NVIDIA Intel graphics card so I think it's why it does not work.

    Please help-

    I have so many things to do and I'm stuck!

    JJ

    Hello

    I think I can help you ;)

    All Intel (any laptop) graphics cards support the same shortcut keys.

    You can rotate the screen of the laptop by using these buttons:

    CTRL + ALT + UP = turn to normal
    CTRL + ALT + LEFT = rotate 90 degrees
    CTRL + ALT + DOWN = rotate 180 degrees

    and so on.

    PS: You can use this keys only if an option called enable hotkeys has been verified.
    You can disable this in Accelerator Intel GMA. You can reach this through the control panel or properties of the graphics card-> settings-> advanced.

    Good bye

  • Satellite L350D (PSLE0E) - WIFI hardware switch does not work

    Hello!

    Next problem: since yesterday, I have Windows 7 on the laptop, almost everything works perfectly. Not been necessary to load the drivers from the Toshiba site, Win 7 provides with the pilots, the rest comes via update...

    What does not work is the Wi - Fi switch. Whether on or off - Wi - Fi connection is always on, or in other words, the switch has no function.

    Someone at - it similar experiences and perhaps the solution?

    Thank you and excuse my English

    Hello

    This strange because the hardware WLAN switch should always work because s he based material s

    Anyway, in your case, I'll try this:
    -Updated the BIOS and load default settings
    -Update the WLAN driver

    One more interesting thing: can you turn the WLAN functionality by using the FN + F9 key combination?

  • Satellite P750-136 - left mouse button does not work

    I don't understand what the problem is. My left mouse button does not work. If I put a little pressure on the Panel located under the button space then the left button of the mouse works.

    What should I do? It feels like a hardware problem, since I bought the laptop in November my laptop is still covered by the warranty.

    What you can do is to check the touchpad settings and make sure that everything is OK.
    I'm don't know if you noticed this since day 1, but if you think it is hardware problem I recommend you contact the nearest Toshiba service provider as soon as possible. Warranty will cover all repair costs.

  • Satellite P750-05F reserved graphics memory and best driver nVidia

    For the graphics GT540M said he dedicated 2 GB, 4 GB available.

    Obviously 2 gig of system ram is reserved for graphics. How can I cancel it?
    I think that 2 gig dedicated is more than enough.

    I want to free the RAM of the system 2 gig reserved for RAM in the system.
    I can't find any bios or graphics driver for this options?

    Also, what is the best driver nvidia latest to use for best performance on this laptop?

    Share the graphics card only if memory his need. But you can't change it manually. This is controlled by the graphics driver and the whole process is executed automatically.

  • Satellite P750: Impossible to install the Bluetooth Stack on Windows 7 (x 64) driver

    Hello.

    I own a * Satellite P750-02 t * (part No. * PSAY3A - T 02 001 *).

    In the order I did:

    (1) I formatted the HARD drive and reinstalled the operating system of * Windows 7 x 64 Ultimate SP1 *.

    Then I downloaded * ONLY the BIOS and drivers * of [his downloads page | http://www.mytoshiba.com.au/support/computers/satellite/p750/psay3a-02t001/download?os=25]:

    (2) I've updated the BIOS for * v1.90* (the laptop came with v1.80)

    (3) I have installed all drivers:
    -LAN and WiFi
    -Chipset Intel latest (available)
    -all video drivers (NVIDIA Graphics, Intel HD Graphics and Intel HDMI)
    -Card reader
    -Realtek HD Audio (later)
    -Synaptics Touchpad
    -USB3.0
    -IR
    TV tuner
    However, I * cannot install Bluetooth driver (v8.00.06 (T) *)...

    When I run the installation program of the [aforementioned page | http://www.mytoshiba.com.au/support/computers/satellite/p750/psay3a-02t001/download?os=25] it detects partially *'Bluetooth USB Controller-10 TOSHIBA'* (USB\VID_0930 & PID_0215 & REV_001)
    and then the installation freezes simply displaying + "install the Bluetooth driver. Please wait +.' and stay like that forever...

    I also tried to download a driver [another location | http://aps2.toshiba-tro.de/bluetooth/index.php?page=download-toshiba] for laptops TOSHIBA - v8.00.02 (T):
    and followed installation instructions displayed under "Details".
    but he had the same result: the installer simply crashes...

    Install fix (* KB978258 *) recommended it did not work either - the message "+ update is not applicable to your computer +" appears.
    And I understand why - this fix is [already included: http://download.microsoft.com/download/E/B/A/EBA55FE2-373A-4351-9346-6D762B79AA69/Updates%20in%20Win7%20and%20WS08R2%20SP1.xls] in Service Pack 1 for MS Windows 7.

    I spent hours searching the Internet for a solution. Although there are some similar cases, none of the recommendations actually worked. I tried to install:
    -WiFi driver before installing the Bluetooth (someone suggested that these two are parts of the same card);
    -Repeat Mode Setup without failure;
    -* Toshiba value added package * hoping that somehow these tools will kick in.
    Nothing has worked...

    It is interesting to note that when, in the interests of experimentation, I tried to run installation for my generic Bluetooth adapter (using the driver [for non-TOSHIBA notebooks | http://aps2.toshiba-tro.de/bluetooth/index.php?page=download]) then everything runs smoothly!

    * Using connection Bluetooth on this laptop is absolutely crucial for TI
    I hope that I won't get back this beautiful laptop as I know that TOSHIBA is one of the best manufacturers and I am sure, that there is a solution to this problem.

    Thank you very much.
    Evgeny.

    specified on the use of another generic Bluetooth adapter with non-TOSHIBA driver

    You can use the key combination FN + F8 to toggle WLAN?
    You can also see BT symbol there?

    Before you begin installation battery BT try to activate BT module by using the FN + F8 key combination.

    Generally avoid some problem with it. Toshiba BT stack is tested on al models proposed by Toshiba and fireplace installation BT has, in my view, nothing to see what version of Win7 you use.

    Do not return this laptop. It has to do is just install drivers, tools and utilities. Please note: BT stack is included in the recovery image so BT must work.

    Also, I must say that OS installation of drivers, tools and utilities on Toshiba laptop must / should be installed in the correct order. Many tools can work only and must be installed on basic stuff that can be installed with other specific tools of Toshiba.

    Please send a few comments if this FN + F8 will work.

  • Satellite P750 Win 7 update for Windows 10

    Hello everyone,

    I was recently offered to upgrade my Satellite P750 (PSAY3E-01K00WY4).

    I'm getting confused because of these things. On the list of devices allowed for the Toshiba upgrade I just discovered that my model is not on it.
    However, I managed to install Win 10 and use it for about 20 minutes when error "unhandled exception in thread system" approached. Found out that it is thanks to the inadequate graphics card or its driver.

    Could you confirm me my device is not appropriate for the upgrade and tell me is there a way to upgrade the graphics card because I really like my Toshiba?

    All the best, Bravo!

    Try to extract the exe from another place, not in the temp folder.
    In my case, I created a folder on a second partition (D) and have extracted the exe file in this folder. Can go to the Device Manager, and then can install the driver through the Device Manager.
    Choose the installation procedure advantage and point to the folder that contains the extracted files.

    With regard to the issue of the BT;
    Download the new battery of BT from here:
    http://APS2.toshiba-tro.de/Bluetooth/

    Then clean the registry using the CCleaner.
    This tool is freeware and can be downloaded on several different pages.
    So after cleaning check if you could install new BT of the register stack.
