Satellite P875-102: how to choose nVidia GPU to run in battery mode

Hi all

Displays the first time since a long time owner of laptop Toshiba.
Just bought a new P875-102, which I am very happy with (non - HD 1600 x 900 screen is the only downside).

In any case, I was wondering if there is a way to force the machine to use the graphics card from nVidia while on battery? Graphics performance through the floor when I unplug the power cable which leads me to believe that it is not through the nVidia card for the integrated Intel chip for low power.

I am aware that without a/c running nVidia card will limit my battery life, but I prefer to control this manually. The "eco mode" switch is fine for this.

The Setup is standard factory: Win7 x 64, 16 GB RAM, Nvidia GT 630 M GFX.

I checked the settings of the Intel and nVidia control panels and have done everything to use the nVidia card. I also checked under Win 7 power plan settings and everything put on max performance on battery.

I'm running out of ideas about where search - any advice would be greatly appreciated!

> I was wondering if there is a way to force the machine to use the graphics card from nVidia while on battery?

Optimus technology automatically switches between the internal Intel HD gpu and nVidia GPU in order to save the battery.

But you can force and simple application to run and use the nVidia GPU.
This can be done in the nvidia Control Panel.

1. click on start and then Control Panel. Select Classic view in the left side of the window.
2. double-click on the NVIDIA Control Panel.
3. click view, and then add the "Run with graphic processor" Option to the context Menu. Close the NVIDIA Control Panel.
4. right click on the title of the application and select run with GPU. Then, click on NVIDIA processor high performance.

  • Satellite P875-102 - sound freezes when the CPU is busy

    Hi guys,.

    I just bought a Satellite P875-102 with Windows Home Premium and all software by default, and card and I have a very annoying problem with the sound. Whenever the processor takes a little more time to process information (i.e. a website load) sound freezes for a second and then comes back.

    It happens with all my music software and regardless of local or streaming music. Is there a way can I fix? It gets really, really boring and it is a laptop which should do much better than the one with multimedia...

    Any help would be welcome. Thank you!

    Hello

    When I read something like that I would like to have mobile phone in front of me and see exactly what is happening. New portable computers are preinstalled with Toshiba recovery image and they contain about additional software running in the background.

    Windows Update set to automatic when you buy new laptop and connect it to the internet, I think first of all days notebooks are very busy with the update of various facilities and all this happens in the background.

    Updates collection pre-installed antivirus, scan disk and all these activities slow down s for laptop performance. Result can be these thresholds when you listen to music or watch movies.

    What to do with the new notebook is the optimization of the OS. With other words, I dsable Autostart for many applications that I n t need, remove preinstalled antivirus and install Avira antivir, disable updating automatic Windows and, at least, remove some stuff preinstalled system.

    After this start is much more fast and portable ready for use. I can't say for sure, but I think you should do the same thing and check if this problem occurs again and again.

  • Re: Satellite C660D-102 - how to copy Windows on DVD?

    Hello people. I bought a new Toshiba Satellite C660D-102.

    The seller told me to copy Windows on DVD soon to open the laptop. Don't know where to take the Windows installation files. You have encountered this problem? How can I solve this problem.

    Hey,.

    I think that the seller meant to create the Toshiba recovery disc that contains a picture of the factory settings. In the case where you can start t more Windows or the drive HARD must be replaced, you can use this disk to restore Windows with all the drivers and tools. With other words, you get factory settings back, the same settings as you bought the laptop so it of very useful and easy.

    You can create this disk if you start creative media recovery Toshiba which is preinstalled on your computer. According to the installation, you need certain blank DVD media. I recommend high-quality mediums, type: DVD-R from Verbatim or TDK. They work well and others here can recommend them also.

    Last but not least, you should also read your user manual. It contains interesting information on this subject and other interesting things. It s also preinstalled on your laptop. :)

    But it s really great, the seller gave you an indication in this regard. If you check the other forum discussions you will read a lot others that they forget to create this disc and are not able to restore the factory settings if Windows could not start.

  • Satellite A500 - 17 X - Games slows down if I play on battery mode

    Hello
    When my laptop (Satellite A500 - 17 X) is connected, the game I play (Call Of Duty 4) works very nice, but if I try to play the game while my laptop is on battery, the game slows down. If you know what I mean.

    Is this supposed to happen because the graphics card does not work well when the notebook is on battery or something wrong with my laptop?

    Hello

    That's is a bit strange, I've never had such a problem and I don t often play on battery mode, only on AC/DC adapter.

    The only idea I have for the moment, is that you should check the power Windows settings. Maybe in the power profile that you use is something different for battery operation, e. g. CPU maximum performance set to 50% for battery operation.
    Check it!

    Here is a good article on these parameters:

    > Is it possible to format with an OEM - XP cd?
    > Is it possible to get the Toshiba help or not?

    You need a Setup disk if you want to install a Windows XP operating system.
    Unfortunately, the laptop seems to be very old and I don t think you will be able to order a recovery disc, you will need to purchase the Microsoft Win XP.

    After Installing Win XP boot, you can download all the drivers for this laptop from Toshiba's European driver page. The drivers are located in the archives. (on page Toshiba European pilot, in product type click Archive instead of the laptop)

  • Satellite P875-102 - touch pad / cursor freezes regularly for 2-3 sec

    Very happy to get very new P75-102 Toshiba (Windows 7) - £1. 1 k - WAITED so it works well immediately the day 1 - from the box. Unfortunately, the cursor on a regular basis (either 5 - 6 times in a surf web minutes) hangs for 2 to 4 seconds. Everyone knows that with this very recent machine?

    This has nothing to do with the speed / sensitivity settings - it is intermittent gel that makes use of the laptop really frustrating. The official troubleshooting says that the system could be busy - but I have nothing else running and the CPU usage is minimal, no surprise given the power to the computer. Help, please!

    From my personal experience this could happen due to stressed CPU.
    Even if you do not use a heavy performance, the NECK may be stressed due to the background processes that should be launched when the laptop starts
    So I would recommend checking the processes in the process tab (CTRL + ALT + DELETE) Task Manager.
    Here you can see which process stresses the CPU and can disable it if possible.

  • Satellite A200-1AE: How can I configure the settings of buttons Dual Mode Pad?

    Hello

    I recently bought a Satellite A200-1AE. I tried to configure the default first button on my touch pad (lower left) so that I can fire up MSWord, but it did not work.

    Now every time I have set the mode button and press this button, that nothing not to pass - I lost practically this button.

    My question is how can I configure the mode button on the touch pad settings? Even if I was able to start a program by using the 3 buttons how can I modify these programs?

    Thanks for your help!

    p.s. I read the extended version of the manual for my laptop. There is no explanation of my problem - it says I should look "Synaptics Dual Mode Pad properties.

    I don't know where are these properties.

    Hello

    It s is not so difficult as you think, the properties of the synaptics are in the "mouse properties" of your "Control Panel" of windows. When you reach the 'mouse', then click on the "Advanced" tab and you should find a button 'Advanced functionality settings'.
    It could be that the button is not named as mine, but it must be identical.
    After clicking on it, you should look for this 'easy' Launcher in one of the tabs.

    I think that you will make it, but I'd like some feedback from you.

  • Battery does not charge, but by Satellite Pro L510 is running in battery mode

    Hi, I had a few odd battery problems these days:

    I had charged my laptop completely to 100% and then used it on the train on my way home (in Windows 7 64-bit), how I got it to about 70%, shut down normally, put it in my bag and left there until I got home. When I got home, I tried to turn it on but it lights and battery light orange blinking indicating that there can be no charge. I plugged it in and it worked as usual (Linux), so don't think too hard on this subject.

    Later I realized that the battery was still the load after longer that it should have been and running the acpi + (linux) command told me has the battery + charge, 0%, charge at the zero rate - will never fully charge. + I disconnected to see if it worked, and the battery lasted as usual, although always it's 0% charge rate.

    I started in Windows 7, and the battery reported that it was at 68%, so I assumed it was back to normal. A while later, I noticed that he was still 68%, despite having connected for a while - at least an hour. Start on linux, acpi showed data battery normal search, except that it was 'blocked' to 68%.

    I disconnected the laptop and run it as usual, and it ran until he cut; I guess with him out of power. I plugged it back in and it is 'charge' again, even if it is still 0% battery and "load at the zero rate".

    Before all this happened, the battery works well - apparently to 94% of its capacity. It would be modified for a few hours unplugged play movies or games.

    Summary: PC laptop battery suddenly going to works "attributed to the zero rate" and 0% complete; battery still seems to work very well, seems fresh and portable no power plugged in but the battery is not 'charging' or have his percentage of charge remaining increase.

    Someone at - it ideas? I have yet to try a BIOS update, but it seems that there is one available, so I will give that a try. I feel that the problem is not the battery as the battery controller, so I don't want to invest in a new battery without knowing it, the problem will be solved.

    Thank you!

    Hello

    I think you should try upgrading the BIOS
    BIOS default value, and then try to charge the battery again.

    > get the impression, the problem is not the battery as the battery controller, so I don't want to invest in a new battery without knowing it, the problem will be solved.
    Well, it of really difficult to tell if the battery or the mobo may be affected
    In my opinion, the battery must be tested without a doubt

  • Satellite P20-102 - receiver remote not working do not after running recovery CD

    Hello

    I am running Windows Media Center Edition and on my laptop Satellite P20-102.

    I recently needed to run the recovery CD, the process went well except that my box of external remote control receiver provided with my laptop no longer works.

    The box works with XP Media Center Edition and the remote control before I ran the recovery CD. The receiver is detected and installed on the computer when it is connected and recognized in device like a USB Serial Converter Manager. The inner light flashes about 4 seconds. When you press a button on the remote control light both in the housing of the remote control receiver if it receives the signal.

    I guess it's a software problem, I can't find any information on the installation of the receiver or all the drivers for it.

    Any help would be greatly appreciated.

    Kind regards

    Hi Paul

    I also P20 but unfortunately without MCE. I can't give you any help, but in my opinion, you should try to contact Toshiba hotline in your country. Maybe it's possible that one phone call can help you manage this matter in the right direction.

  • How to use card NVIDIA on the Satellite P875-321?

    Hello

    I have a Satellite P875-321 with operating system factory upgraded to Windows 8.1, all the latest drivers installed.
    Whatever I do, it seems built in graphics card is used only (Intel HD 4000) and the Nvidia GT640M is never used.

    I check this:
    1. with the NVIDIA Control Panel (PhysX configuration shows that all screens are connected to the Intel HD 4000
    2. in resolution 8.1 windows settings / special settings lead me to the Intel HD 4000 properties, which indicates that this card is active

    What I tried:
    1 leaving everything default and use the external power supply (hoping that the computer automatically switch to NVIDIA when the external power
    2. use control panel NVIDIA and NVIDIA 3D as favorite graphics card settings

    Hello

    The Intel graphics chip, which is part of the central unit should be used for low performance applications, because it allows you to save energy and reduce the internal temperature.

    But to get best performance all in game, it s advisable to use the external GPU (nVidia or AMD)
    This setting can be changed in the nVidia control panel s

    Here, you should choose manage them 3D settings (can be found on the left in the nVidia control panel)

    Now in the main window, you will find two global settings and program parameters tabs
    In the program settings tab, select the (game) program that needs to use the nVIdia GPU

    If it is not listed, click the Add button
    Then choose the graphic processor preferred for this program (generally must be nVidia processor high performance)

    Last but no less, in this program-specific settings, you can assign additional features to improve performance.

    HI :)

    I come from Germany and my English is very bad, sorry.

    I need help, because I want to play Worms: revolution on my Qosmio x 770 with a Nvidia GeForce GTX 560 M and it does not work.

    This is the post coming from "support @ team17.

    Hey,.

    Sorry to hear that you are having problems during the revolution of Worms. It seems that your computer is trying to run the game via the integrated Intel graphics card, rather than the dedicated Nvidia GeForce graphics card.

    If you want to run the game through your dedicated graphics card, you will need to consult your computer manufacturers documents or instructions if you are unsure on how to do this, or if you do not have these documents, contact the manufacturer directly.

    Unfortunately, we cannot directly provide you with instructions on how to proceed.

    Hope this helps and thank you for your continued support,
