HP m8120n no Ethernet in the Device Manager and not detected

Hey all:

I have a desktop HP Pavilion Media Center m8120n (product sheet here) and I recently did an installion of installation clean factory, Windows 7 Pro 64 bit with a DVD retail of Windows. I managed to get the drivers for almost everything, but there are some persistent problems.

The most serious of them is Ethernet. I can't find drivers ethernet for this machine, even after the update of Windows running several times, no hardware drivers have been found. The ethernet controller/port is not still appear in Device Manager at all!

I tried to use the driver for this calculation pager on the HP support site, but there is no mention of all the Ethernet/LAN drivers at all.

I read that sometimes it is important to update the chipset first driver in order to get the job of ethernet. Since HP provides no chipset driver, I decided to try updating the chipset 8120n with theutility to update Intel drivers Intel's Support page.  I have updated to version 9.4.0.1017, once the Web page has scanned my system. However, even after the update the chipset and Windows restarts, I have still no Ethernet at all.

Depending on the product specifications page, under the section network, the computer uses a controller Ethernet Intel 82566DC. However, after trying to install the driver for the Intel 82566DC since the Intel, the installer website told me that no network controller Intel were present on the system.

What is really worrying, is that not only does the Device Manager does not even see an Ethernet controller, but the Intel drivers update utility didn't recognize it under the section "Wired" after that the latter had analyzed my computer. Ethernet controller also does not appear under system information.

I'm starting to wonder if it is a hardware issue and not a driver problem at all! The Ethernet port may be damaged or does not work for Windows do not install the drivers, or even recognize it.

Does anyone have advice or steps I could take to rule the hardware problem and find a driver that works for my installation of Windows 7 on this computer?

"Violence is the last refuge of the incompetent." -Issac Asimov, from its roman Foundation.

Good new! It worked! It was really the BIOS that was causing the problem.

On the Advanced Settings tab, there is an entry called Onboard LAN off, just like the desktop I have to work!

After booting, Windows installed the drivers for it right away, and now I get to enjoy this sweet Gigabit speed on my network!

I'm so happy that it was not a hardware problem, and that it was a simple change to the configuration of the BIOS.

Thanks for all your help!

I'm as resolved marker.

  • Download "Bluetooth device driver not installed." with my mobile phone in Lenovo laptop. I could also see a yellow mark on this device in the Device Manager and a code 28 error

    I have a very serious problem about Bluetooth. And it's really frustrating. I don't know exactly what the problem with it, but my problem is as follows

    When I connect my mobile phone via Bluetooth for laptop (win 7 ultimate), my system shows the connection. Also, I see my mobile phone listed in the device window. Earlier, when I brought the computer laptop, everything seemed good, at this time, when I use it to open the device (IE to control ); a window would show the option for playing music (there was a lot of option as a 1 ' headset and speaker") and other services supported by the device. but now, suddenly somehow window appears but with in a 2 sec to disappear again. Whenever I try to open the device I get this error. I must say that it is very very frustrating as you try to move your cursor to click on audio playback on this portable display option, the window disappears. Help, please. Now, let me tell you what I tried to solve this problem.

    I have laptop Lenovo, which has something like that for bluetooth

    Broadcom Bluetooth 4.0 USB

    Microsoft Bluetooth enumerator. I have 32 bits of the system, processor i3, win 7 ultimate, one port wifi

    In the center of troubleshooting, I tried for the material of scanning that show this Bluetooth device driver not installed (I could see a yellow mark on this device in the Device Manager and a code 28 error).

    But windows cannot fix it.  I have tried multiple devices but nothing turned up. also I tried the same devices on different laptops and all of them worked very well.  I checked online trouble - shooting.but not very useful. Please don't tell me about recovery. I don't know when it happened.

    Please help me. Please give me link if there is no download needed

  • External hard drive in the Device Manager but not in disk management

    So I have this external hard drive Western Digital 1 TB. I've had for over a year now and it was working fine. I would like to trade my XBox 360 and the computerregularly. Then one day I brought home, plugged into the computer and nothing. My friend and I couldn't understand anything. We have gone as far as removing the hard drive and put it directly into the computer. I have reviewed, that he has lost.

    Then yesterday, on a whim, I tried to connect it again to the USB port. It is presented in the Device Manager but says that its drivers have not been installed. Then, I changed the USB ports on the back of the computer and as if by magic, that this is once again. I had full access. Stupid (and you can see where this is going) did not immediately transfer anything off the hard drive. I'm looking for an image and listen to a song off of said hard drive when the drive went suddenly not recognized.

    I can see now the reader in the Manager of devices under disk drives, and USB devices. However it does not appear in the disk management window. And Yes, I checked as well the Productdocumentation upper and lower, that it is not listed. Go to the area where you assign drive letters not shown not be. Normally this is E:.

    I also tried to remove the UpperFilters registry in regedit. It was not to remove LowerFilters. Obviously, that didn't work or the other.

    I tried several cords and all my USB ports with no luck either.

    I went on the WD Web site, but they do not offer anything other than a partitioner that I would save rather than as a last resort as there are a number of things on the hard drive I want to save.

    So it's not like it's a new HD to be partitioned or an old man who comes out crapped. I know there's the data I just need to get home long enough to get what I need. Maybe I missed my window, but maybe I did not. Maybe someone can help. I'm at the end of my mind on this thing.

    Sounds like a problem of partition (maybe corrupted partition tables) if the device is recognized, but not the 'disk '.

    There are recovery/repair partition about tools.  Western Digital actually have some but I think that they are made for internal drives.

    If I were you, I start with WD and start looking for partition recovery/repair tools.  If this is the problem then it is the right kind of problem and you using the right type of solution can fix it easily.

    If this is not the case, some data recovery tools can help you recover some files even if you have to recreate a new partition, although I wish you much luck with this approach!

    Good luck whatever you try and make sure that you do not overwrite the what partition information, you have without making backups (many partition edititing software will offer backups)

  • Device Manager does not detect the gpu performance

    Hello everyone, I've had my laptop for a couple of years now. He is currently the normal edition of HP Envy 17 t - 2100. A time back well before this problem I had to re - install windows 7 and of course while I downloaded all the drivers. I was still not able to download the switchable graphics driver / program. I don't know if this is related to the issue or not.

    The MAIN question, I though, is that my laptop no longer recognizes the high performance GPU (AMD Radeon 6850 M). I tried to install the drivers, uninstalling and reinstalling again. But no luck. If someone can point me in the right direction or has any idea what I can do, I would be very gratefull!

    Hi JoshSa,

    Thank you for visiting the Forums HP's Support and welcome. I read your son on your t-2100 HP Envy 17 laptop and graphics problems. Here is a link to your driver and software for graphic design. Download presents first and then uninstall what you have within you the graphics drivers in Device Manager.

    any suggestions please?

    or any other required information?

    Thank you very much.

    It's part of the problem that I do not in the BIOS, I know that many make the CD/DVD of my first startup. I just can't make the first boot from it! What about the second problem which I can't make changes in Device Manager.

    Thanks for your reply.

    Using a portable OEM version or office? They have total control over your system? You can only use it for the calculation of daily life.

    If you can not enter the BIOS so no way to change the boot device priority.

    Better, you contact the OEM.

    How are therefore continue on you can't get into the BIOS? Have you tried several times by pressing "Del" or the "F2" key during startup (when the first time OEM or any screen logo into your monitor after restart or reboot)?

    The Code 10 error code is generated when the Device Manager has not enough information or error that spread upwards by device drivers is not recognized by Device Manager.

  • Bluetooth has disappeared from the Device Manager

    My computer does not detect bluetooth devices. I went to the bluetooth menu and unchecked and rechecked the boxes 'discovery' and so on. However, when I hit apply, the window became unresponsive and I forced to close. When I tried to repeat this, when you type apply I get a Bluetooth Service error message saying my device is disconnected (my bluetooth adapter is built-in). I went to the Device Manager and disabled the Microsoft Bluetooth Enumerator and generic adapter Microsoft to try to restart them. However, instead of just disabling, the owner made them disappear from the list (even show hidden devices will not bring them back).

  • Latitude E5470 TPM has disappeared from the Device Manager

    At my employer, we had several problems with the TPM secure disappears from the Device Manager.

    This brings us to not be able to reactivate bit-locker.

    We would be the image the device with Windows 7 company.

    We had this happen with several machines who did and does not have dealt with windows updates.

    Same thing with Dell drivers and BIOS treated and untreated.

    I ran tool HWINFO and it lists the TPM with a memory address something like 0000FED4000 but I can't find that in the Device Manager or msinfo32.

    I have went to the BIOS and turn off the TPM and it turned on and activated it.

    I reloaded the BIOS firmware.

    If recreate us the image on laptops the TPM appears in the Manager of devices as planned so I don't think this as a problem with the motherboard.

    Curiously, although we had some motherboards replaced and the TPM is displayed.

    I feel that replacing the motherboard is the solution to this question we can restore the functionality with a new image or reload the operating system from scratch. But that does not satisfy the risk of the issue and already its appearance again.

    I searched for weeks a solution to this problem, but I came up short.

    I am sure that others have this problem.

    With all the processed drivers and windows updates treatment it does not solve the problem.

    Think you I'm missing?

    Thank you for taking the time to look into it.
