Lenovo G50-70 Graphics

Hi,
I have recently bought a G50-70 (i7) which comes with the intel HD 4400 and the R5 M230. I've found that there is no way to disable the discrete/integrated graphics at a time. So does this mean that both are powered on at the same time? Also, is it okay if I update my drivers to the latest AMD and intel drivers available? Or is it recommended I use only the lenovo ones?
Thanks,
Best regards,
David

It is recommended using the lenovo drivers, Both the GPU's are not powered up at all the time, your Integrated GPU is the one which is powered all the time, the Descrete just handles the GPU intensive tasks, like gaming. Once that application is fired up as per configuration, the discrete will automatically start processing the game instead of the integrated
Lets make 2015 the year of the #DO

  • Graphics display problems (dialog boxes) Lenovo G50 AMD A6 Win 8.1

    Graphics display problems Lenovo G50 AMD A6 Win 8.1 Greetings to all. After having spent a number of days trying to find a solution to a display problem, I turn to this forum for help. I own a Lenovo G50 AMD A6 Win 8.1 ever since November 2014, and have had display problems ever since the first day, be it while using internet (Firefox or Explorer) or various software (Text editors, etc.). Many dialog boxes, including colour settings and controls (open, close etc.) either have an inappropriate appearance or even do not appear at all! I manage to "click" on the right places using memory: most areas are INVISIBLE! Another example would be that I do not see any backround colour or image on most webpages such as this one).  Some suggestions included checking for graphics updates (but the drivers used were already up-to-date).  I 'd be most obliged for any new suggestions. Thank you very much. George

    Greetings to all, I finally decided to express my utmost discontent with- the Lenovo G50-45 I bought before Christmas 2014,- the summary response with inappropriate links that I received after exposing  my problem- the fact that I tried to dowload the following graphics driver  (Beema) AMD Driver (VGA, HDAudio, SATA) for Windows 8.1 (64-bit)
    exe
    526 MB
    Windows 8.1 (64-bit)
    VGA V14.502.1002.1002-Logo'd_HDAudio v9.0.0.9905_SATA v1.3.1.220;VGA v13.302.1601.1001_HDAudio v9.0.0.9905_SATA v1.3.1.220
    3/19/2015from here(http://support.lenovo.com/fr/fr/products/laptops-and-netbooks/lenovo-g-series-laptops/g50-45-notebook-lenovo/downloads/DS100174), and after REFUSING to accept cookies and some "Lenovo Service Bridge", finally managed to obtain something  HERE(http://www.notebookcheck.net/Lenovo-IdeaPad-G50-45-Notebook-Review-Update.125641.0.html).  I find it quite disrespectful to NOT provide customers with EASY support, as well as avoiding to  answer their requests for further help when some simplistic "assistance" that one can find almost anywhere on the web leads to no further solution. I shall not repeat the problems I have faced till now: vide supra. The problem, however,  is NOT just with browsers.I simply cannot see any dialog box content and colour in MANY software programs, such as OPEN OFFICE; for instance:  PRESENTATION colour dialog boxes show BLANK squares instead of squares filled with different colours. This has occured AVER SINCE DAY ONE! Finally, a new bug has appeared: Windows 8.1 keeps popping up some email program to which I am invited to register - I never created a Windows email account, and certainly don't intend to do so.NOR shall I accept some "Lenovo Service Bridge", however "discreet and inoffensive" it might be. I don't know if there are any legal grounds for customers to complain for all these problems. I DO know, however, that I shall NEVER buy a LENOVO device ever again. The pricing and processor might be competitive => yet,  the support that ensues is, as far as I'm concerned, LAMENTABLE. To make a presentation, I have to switch to a Samsung R20 using XP..... What is the meaning of all this? George

    hi Ashish1793,
    If you're running on Windows 7 64bit, can you consider the following:
    1. Navugate to the Control Panel (icon views) > Display Adapters and uninstall both the Intel and AMD Display driver then reboot.
    2. Install the Intel Display Driver first then reboot.
    3. Install the AMD Dislpay Driver (the files will be extracted drivers to the C:\Drivers\VGA folder - overwrite if prompted and reboot if necessary)
    When finished,  you should now have both the Intel HD Graphics 4600 and AMD R5 M230 in the Device Manager > Display Adapters
    If you get a Code 43 error on the AMD Display Device Manager, try to install the AMD R5 M230 driver directly from AMD website and observe.
    If you have Windows 8.1, download the Intel and AMD Display driver from the G50-70 drivers page and install them respectively.

  • Lenovo G50-30 Can't adjust the brightness

    HI 
    recently i bought a lenovo G50-30 laptop with windows 8.1(64-bit)
    the performance was low and i downgraded it to windows 7 professional (32-bit) which improved the performance drastically,
    Now when ever i try to install the vga driver i get this message saying "this computer does not have the minimum requirements for installing
    this software",and also i cant adjust the brightness
    Did i do anything wrong,does anyone know what to do
    please
    Thanks

    sorry for the late reply, here's the things you can try , try rolling back the driver or you can access the registry to adjust some values here's the step:
    1- install latest driver of your graphic card
    2- This step will fix the problem:
    3 go to registery by regedit and change the value to 0xf048
    [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000]
    "FeatureTestControl"=dword:0000f048
     OR
    [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0001]
    "FeatureTestControl"=dword:0000f048

  • Lenovo g50-45 aceleradora de graficos

    hola a todos y agradezco a quien me pueda ayudar, tengo una lenovo g50-45 procesador AMD E1-6010 APU with AMD Raedon R2 Graphics 1.35 GHz, RAM 4 Gb, disco duro de 500 Gb, y quiero saber si puedo adaptarle una aceleradora de video y cual me recomiendan. gracias

    Hola piplup que tal,
    Este modelo no cuenta con una pantalla táctil lo que supondría que no consigas un repuesto o pieza para este cometido, pantallas externas con la tecnología táctil en el mercado existen pero el precio es elevado.
    Tu segunda pregunta no la entiendo bien, el menú inicio te manda a la nueva interfaz metro de Windows en donde existen acceso a aplicaciones divididas por rectángulos , de estos rectángulos tienes problemas con tema color, este problema solo sucede en esa interfaz o en general.
    Un saludo.

  • Lenovo g50-30 sudden crash

    Hi everyone! I bought a new lenovo g50-30 (i am not sure about the correct serial but maybe like this or similar: g5030116aus).
    My problem is that if start a newly installed offical win 8.1 with basic options after a 20-30 min using the laptop going to black screen, and crashes. Restarting and the win 8.1 loading again. Sometimes it`s stops just after the booting, sometimes after 5 minute using win 8.1. One time I`d like to use the music player with headphones and the OS stopped  and the headphones gave me a scratching, annoying noise.
    I tried with an my old win 7 OS from my old laptop (yes I know should install a new but I hadn`t much time). Same problem, especially if tried to run videogames.  I installed the basic drivers like amd vga driver, lan and wlan driver etc, so the win 7 worked fine. But I started a R6V2 (rainbow six vegas 2)  and stopped after starting. Second time stopped after I quited from a the game.My question: Have anyone same problem and could give good solution to fix the problem?
    Second: Could be a problem, that I laying in my bed, and moving my laptop then it crashes because of denting the inner parts?
    Sorry for my english I am not good at that.  Thx for the help

  • Lenovo G50-30 - "No Bootable Device" error message when trying to install windows 7 via DVD-ROM.

    Hi all, Recently purchased a Lenovo G50-30 as a birthday present. After recieving the laptop, I tried putting a fresh install of Windows 7 64 Bit onto it. After changing the BIOS settings to allow legacy booting from the DVD drive and changing OS Settings to Win 7, I noticed I was getting an error reading "No Bottable Device -- Insert boot disk and press any key". After googling for a few hours on how to fix this I am still stumped and nothing seems to work. Has anyone had a similar issue or would know how to fix this?

    Hi omegafeggy,
    Welcome to Lenovo Community Forums!
    Im kind of confused with the sequence.
    Have you installed Windows 7 first then change the BIOS or You changed the BIOS first then Load Windows 7.
    Thanks

  • Can't find drivers for Lenovo G50-30 for Windows 7 32-bit

    Hi,
     I can't find drivers for Windows 7x32 bit for my new Lenovo G50-30. Looks like Lenovo support doesn't have them. Am I wrong?

    hi ziris,
    Can you try these drivers:
    Chipset:
    Intel® Chipset Device Software (INF Update Utility)
    Bluetooth:
    Bluetooth Driver (Intel, Atheros, Realtek, Broadcom)
    Camera:
    (AVC, Bison) Camera Driver
    If the  above drivers doesn't fix the unknown device under Device Manager, can you follow this guide on how to install the drivers via their Hardware ID or you may want to consider installing Windows 7 64bit (this would be best if you'll be utilizing 4GB RAM and above).

  • Lenovo G50-30 Unable to access BIOS settings after Windows recovery

    Hi
    I recently 'downgraded' a recently purchased Lenovo G50-30 with preinstalled Windows 8.1 to Windows 7 using a UEFI USB install on a GPT partition. I also updated the BIOS from A7CN40WW to the latest A7CN43WW and all was working fine. However, after performing a necessary restore of an system image created using the Windows 7 backup and restore tool, I am suddenly unable to access the BIOS settings, either with the novo button (I do get the menu to select BIOS) or with Fn +F2. All that happens is that I receive a blank screen with a static cursor in the upper left corner. I can however still access the boot menu Fn +F12. This is a particular pain as I obviousl can't select USB 3.0 in BIOS.
    Any help here would be greatly appreciated.

    OK, I managed to clear CMOS by disassembling and desoldering a leg off the the RTC battery but to no avail. The problem seems to be that BIOS a7cn43ww itself has somehow been corupted. In theory this should be able to be resolved by a reflash. The trouble here is there seems to be no way to reflash with a current or previous BIOS version, so I'll have to either wait for a newer version or someone may know better.
    C'mon Lenovo support this simply isn't good enough. It's a brand new laptop and I'm considering returning it for a refund.

  • Lenovo G50 BIOS in this system is not fully ACPI compliant

    Hello everybody !
    I kinda have a problem as the title states.My neighbour has a Lenovo G50 she bought and came with windows 8.1 x64 ( which she doesn't like at all and in my opinion win7 is far more superior ). The thing is I wanted to install her the Windows 7 Ultimate but everytime the " loading files " ends right after it boots from the dvd I get a bsod with the message " The BIOS in this system is not fully ACPI compliant Stop 0x000000A5 "
    I tried all kind of different settings through the bios, changed from UEFI boot to Legacy / disabled secure boot / fast boot / I set the ACHI to compatible / but the end result is almost the same ( two times with different settings my screen froze with a red line over the top after loading the files )
    My question is what is the problem and is there a fix for it? (of course it is,but I don't know it )
     Thanks !

  • LENOVO G50-30 stuck at lenovo logo and cant even enter bios

    Hello
    I yust got my lenovo G50-30 and wanted to install win 7 on it. after the first BsoD I went to bios and changed the AHCI to legacy mode. Got the same BsoD.  After that I changed the Os mode from win 8 to win 7 ... loaded the factory default settings and putted from AHCI to legacy mode again.
    After that the laptop turns on, but it stucks at lenovo logo. I cant access the bios anymore to make any other changes. If I insert a win7 instalation disc, it start to spin but with no sucess. also cant acess the boot options anymore.
    Any help greatly apreciated

    I suggest removing battery and AC, holding the power button for more than 15 seconds to reset the BIOS back to default settings then see if the issue remains.
    Make sure to post the results.
    Good luck.

  • Lenovo G50-70 HDD Ticking Sound

    Hi I bought my laptop last august, now its HDD makes ticking sound when idle but it is fully functional. That sound is very annoying .

    Hi Stchoy903,
    Welcome to the Forums.
    As per the query we understood that you are facing issue with unable to detect external HDD and DVD ROM in your Lenovo G50-70 laptop.
    Check any other USB devices like pen drive, or your mobile through USB cable and check if the devices are detected? If yes then it might be issue with the external HDD and DVD rom, also check this devices in other USB ports as well.
    Boot the system into and check if the USB ports are enabled, if disabled enable it. Also boot the system into safe mode and check for the issue.
    Best regards,

  • Lenovo G50 NOT plugged in, but 'charging'.

    I just bought a new Lenovo G50 about a month ago. The only strange problem I have picked up in the last 2 weeks, is that even when my notebook is NOT plugged into the charger, it still indicates that it is charging from an incompatible power source. Where my previous notebook, warned me on 10% battery left, my new Lenovo does not, because it is under the impression that it is 'Charging'.
    The battery life is not really affected and when plugged in, it charges the battery normally.
    Can anyone help me with a solution, before I take it back to my supplier. I know simple fixes like this can take up to WEEKS if I have to take it in.
    Thank you in advanced.

    hi dentonbronkhors,
    Welcome to Lenovo Community Forums!
    Can you try these steps:
      Open Device Manager and look Under Batteries, Right click and uninstall the item Named Microsoft SCPI compliant control method battery.
      Shut the computer down instead of doing a restart like the computer ask.
      Now Remove the Battery and Unplug the Ac adapter, Hold the poer button down for at least 10 sec.
      Turn the computer back on and See if that resolves the issue.
    Let us know your findings
    Cheers!

    Thanks
    - Kasper

    Hi
    Welcome To Lenovo Community
    The graphics card in your machine is actually a chip that is incorporated on the motherboard.
    It's not upgradeable.
    Manufacturers use a lot of notebook components to keep the profile slim. 
    Hope This Helps
