Reference Dell E6540 - ATI Radeon HD 8790 M does not appear in the BIOS

Hello

I have a Dell E6540, which, according to the data sheet must have a graphics card than ATI Radeon HD 8790 M. but looking in the BIOS, there is no entry in addition to the dedicated graphics card Intel 4600.

I have the latest version of the BIOS and the latest graphics card driver. I am using 8.1 Windows 64 bit.

Please let me know if I need to do something else to make it the primary video controller.

Also, is it possible to see if the graphics card is "there"? I think that if it does not show in the BIOS menu, either is missing or broken.

Any help is appreciated.

Thank you
Teo

There are two ways to create a mobile video hybrid:

1 hardware control - with a multiplexer equipment

2 control software, where only the GPU from Intel is hard wired to the display and the secondary GPU is used as a coprocessor.

Your system is of type 2.  It is not a true independent GPU - this is a coprocessor for the Intel's GPU, fully controlled by software and drivers.  To use the AMD GPU, choose using the Catalyst Control Center under Windows.

The AMD GPU can never primary rendering on this system: it's a secondary GPU by design.

  • Windows 8.1 does not appear in the store Windows Dell XPS 8700

    My desktop computer Dell XPS 8700 arrived yesterday, but I can't upgrade Windows 8 to 8.1 of Windows. I went to several Microsoft Web sites where they say on a Windows update and I have to have before the upgrade is displayed in the Microsoft store. I checked I did all Windows updates available including
    you need to upgrade to 8.1. I tried "wsreset.exe" running to clear the cache of Windows store. This is not a business system. It's a regular OEM Dell version of Windows 8 that came with the machine. No matter what I do the update does not appear in the Windows store. I thought maybe since I was using the same Microsoft account for my laptop I already upgraded 8 to 8.1 that maybe he thought I was already updated. So I created a new account of Microsoft, created a new user, delete the old user and tried to get the upgrade as a Microsoft account fresh and a user. Still no luck. I saw another person posting a message on a forum somewhere that had a similar problem on this exact model as the only answer that I was to go to the Microsoft page that tells you to do what I've done. Any suggestions or websites where I could crosspost this problem would be much appreciated.

    I copied and pasted the steps below from another thread. The procedure worked for me both my 8700 s after that I had tried just about every other proposed solutions. I hope that the procedure will work for you too (assuming that you have not already tried).

    (1) uninstall KB2871389 and restart.

    (2) download the update of Microsoft KB2871389--> http://www.microsoft.com/en-us/download/details.aspx?id=40098

    (3) manually install the KB2871389 update and reboot.

    (4) you must now (I hope) see the 8.1 update in the Windows store.

    Hello, I have a Dell Dimension 4600 older XP. The hard drive is dead and I replaced and then reloaded pack 1 with the intention of making all the revisions on the internet. The problem is that I cannot now connect to the internet via my broadband router directly connected to the computer. It seems that the wizard to connect only wants to use the dial upward and does not connect to the router. Just recompose. It seems to ignore the connection from the router to broadband and wants to use the dial upward only.

  • My computer does not load past the Bios Dell screen

    Vista 32 bit Home Premium on Vostro 200
    Hey, my name is Christian and this is my problem:

    It all started last night when I (stupidly) decided I should change my screen windows open, you know, black screen, where the green bar would float through from left to right while the computer responsible. I decided to change to a sort of landscape of Lake, but this is not the point.
    Before that, I chose at the next restart, the registry would be defragged and there would be controls memory.
    I am so down and restart the computer.
    Computer turns on and I the landscape to the instead, loading screen unless it's just a picture, so there is not move bar telling me whether or not the computer was loading.
    And the screen just wouldn't change. I assumed that defragments the registry and memory check took place, but I was rather paranoid about whether or not something is going on I turned manually the computer off hold the button down.
    I turned it back again and he went to the same - screen landscape and would not pass as usual. Paranoia took ahold of me and I turned it off once again. I did it a couple of times (and I apologize) until a system repair came automatically.
    I thought it was my way out of this problem, but it didn't really fix anything, and the screen landscape had changed now in a black screen which seems to have a background image screen to vista aurora discoloration in the Center.
    And it's right now. It does not seem to go beyond that and I think now that it was all due to the change in the loading screens.

    I even left on overnight assuming the scans took place and it would be frozen until the tests were performed.
    Nothing has changed.

    I tried the obvious; safe mode does not work exactly. I click on it and all I get is the names of the drivers being loaded then a very slow black line through every driver leading one by one.

    Unfortunately, I deleted the backups of my restore system checks an hour before this happened and I did a lot of memory by pressing F8 and choose the option.

    I'd even do a factory reset as long as I've had all my files and drivers on a hard drive.

    I don't know what to do, I am completely distraught. Any advice would be helpful and thanks in advance!
    (a factory reset would be VERY VERY last resort)

    Christian.

  • I have re-installed Windows Vista on my laptop (Dell Inspiron 1525) and now my wireless does not work.

    Hi, I have re-installed Windows Vista on my laptop (dell insparon) 1525 and now my wireless does not work. ive tried re installing driver, but it says operating system not supported. I used the disc that came with the computer of the re install and I even tried to install service pack 1. .

    original title: Wireless problems after install.

    I just tried both, the dell is one that says OS not supported"and the intel, it went very well, but my 'network controller' still have a yellow top thing in Device Manager. and I always wireless. any other ideas? Thank you for the help

    Question...  You have whatever it is listed in the "Network adapters" section of "Device Manager" now?

    While ensuring that the exclamation point is not for your wired network device (plausible) or bluetooth (plausible) and you just need to configure your wireless network to connect to * your * wireless network now.

    You may have to contact Dell to see why none of their drivers receive your wireless device works on the original operating system, what they included.  This could be a hardware problem PURE.

  • Dell Vostro 430 sometimes breaks down and does not find the hard drive in the bios

    So I have this old - ish Dell Vostro 430, intel cpu, windows 7 hard disk sata 250 GB, 4 GB of ram.

    Update BIOS to the latest version 2.4.0

    In certain exceptional circumstances, this PC sometimes crashes in windows, it is restarted, and then when he comes back it does not find the hard drive as a gift. He is not seen in the bios and does not start.

    To fix, I have to unplug the power cable, wait a few seconds, plug in, reboot the computer and it starts normally, load windows and everything.

    So far, I have tried to paginate on another hard disk, reinstall the Windows operating system from scratch, and same thing happens from time to time.

    It is difficult to find the cause of the problem, because this happens very rarely.

    Sometimes, when the pc is turned on for the first time in the morning, the hard drive is not found by the bios and we reappear at the same trick (disconnect the power cable) to take him back.

    When it crashes when using inside Windows, it seems that the reason is the computer can't find the hard drive.

    Such computer is out of warranty.

    It would be nice to just throw this computer because it is still fine for the work it has to do, + I have Windows and Office OEM license on it, as well as many other software that I have to reinstall etc.etc.

    No idea what I could troubleshoot?

    Maybe change the motherboard? How can I buy a new motherboard for an out of warranty Dell?

    While possibly keeping all the OEM licenses (Windows 7 and Office 2007).

    Desu
    .. .once in a while...

    That will make hard to resolve this situation.

    • Have you tried to replace the battery in the motherboard, if nothing else than to exclude it? CR2032, 3-volt lithium-ion, ~ $2 at discount stores. Do not forget to open the BIOS Setup and copy down all current settings first because remove battery BIOS resets the default values, which is maybe not correct for your specific system.
    • Have you tried another SATA data cable, or reinstall the existing at both ends?
    • Have you reinstall RAM and PCI card in their slots?
    • Have you used canned air to blow out the dust?
    • Maybe a power supply problem... ? If insufficient voltage, he could not start the HARD drive quite fast at startup, or quick enough after your option settings to be able to turn the HARD drive off when it is not accessed, what may cause this error message 'not found '.
    • If you use a power strip or surge protector, have you deleted and the PC connected directly to a wall jack?

    If it is a motherboard defective and you replace it with another jury of Vostro 430, you shouldn't have any problems with Windows or Office licenses. Assuming you are using Windows Dell reinstall for exact same version of Windows drive that was installed at the factory, it should not even ask the product key, if you must reinstall Windows on the HARD drive. But even if she asks, there should be a sticker somewhere on the PC with your unique product key so you can enter if the installer made the request.

    and make sure you have the Office product key too...

    Hi Kalyan,

    From my research, this error message indicates that you have an old version of Samsung drivers installed on the computer.

    Several clients are faced with this question after that they have updated the version of Android to 4.3, but the version of the driver is not updated.

    I suggest you uninstall all traces of Samsung is installed in the list programs and then reinstall the device drivers Samsung from the link provided in the previous post.

    To uninstall a program see the link below.

    Uninstall or change a program

    Once you uninstall programs related to Samsung download and install the drivers for Samsung devices.
