Coprocessor, Aspire 7530g Drivers
Dec 6, 2009
As I was exploring my Aspire 7530g I stumbled upon an uninstalled component, the "coprocessor".
Device Status:
"The drivers for this device are not installed. (Code 28).."
I did my research and found a mass variety of solutions.
I opened Everest and saught out the unit myself.
nVIDIA MCP77 - Management Unit
I asked my good friend google for some drivers and how to's.
I downloaded and installed the latest drivers to my Nvidia 9400m.
Alas, the effort led me to the same climax of me having an uninstalled CoProcessor.
Am I supposed to install M-board drivers, suggestions?

I installed Windows 7 Beta Build 7000 (from official windows site, but i got a windows key from a friend of mine ^^) a couple of months ago, its all working fine.I recently installed the Windows 7 drivers available at Nvidia.com for my Nvidia 9500GT and got a noticable FPS boost.Today when I was just browsing some stuff i noticed that I had 2 driver errors:
USB Camera <-- old thing, bought it years ago, so screw that xD
Coprocessor <-- No further information given O.o
so I tried to use the troubleshoot thing by rightclicking on my computer (with the yellow sign next to it ) and clicked Troubleshoot. It tried to reinstall the coprocessors drivers, but couldn't find earlier drivers so it failed.so now is my question: What the hell is my coprocessor? Could it be the onboard Nvidia geforce 7050? I personally doubt it becouse when installing Windows 7 it showed it had downloaded the WMD drivers from windows update for the 7050 and the 9500...

I have an AMD Phenom II X3 710 2,5 GhZ, and after fiddling around some in the device manager I notice that the "coprocessor" is unknown, and I can't find drivers for it.I've an nVidia 8200 chipset with plans on changing to AMD 890GX/SB850.As a sidenote I'd actually also like to hear the experience of you wise fellows if any has tried changing motherboard without reinstalling windows.

Location: PCI bus 0, device 1, function 3 .
The drivers for this device are not installed. (Code 28)
There is no driver selected for the device information set or element.
To find a driver for this device, click Update Driver.
The above is found in my Device Manager under "Other Devices" "coprocessors" . I have already tried to install drivers for my sound card (Win 7 drivers are available)but when I do , Im told they dont need to be updated, I have the latest edition. I assumed the coprocessor was my sound card because I dont have any sound. Im tempted to do a system restore ! My m/b is a MSI K9N2 Diamond.

I have an HP DV6500 with an AMD TL-64 processor and the NVidea GeForce 8400M GS graphics card. It's the rs085av model.
I recently installed Windows 7 Pro 32 bit, and I managed to install all the drivers except for two items. It shows "Coprocessor" and "Unknown Device" as incorrectly installed. I don't know what the Unknown device is, but it might be my cd drive (slimtype DVD A DS8A1P ATA), which also isn't working. Also not working is my Ethernet port, which is on the motherboard.
So, if anyone knows what drivers I need to grab to get those to work, or if I need to reinstall the chipset, I would love to know.

I have an AMD athlon 64 x2 dual-core TK-53 processor but i can't find an driver for the coprocessor not even on the offical site. Windows say's in the device manager that it isn't working properly because there are no drivers installed.
I am getting this message... The drivers for this device are not installed. (Code 28)
This is resulting in my laptop in crashing regularly and windows tries to recover the display driver.
I have a HP dv6525 with 7150M / nForce 630m - driver version 7.15.11.7948.
Running Win 7 Pro x32 bit.

After installing the new drivers from Nvidia (195.62, 197.16 and then 258.19) I still have the drivers for this device and are not installed (code 28) error. I have tried to uninstall the driver and re-boot the machine and windows finds the hardware and I get the same error. When I updated the driver, I download the driver file, go into the extracted directory and run the setup.exe file. Then I go to the device manager and update the driver for this device and specify the directory for it to search on my hard drive. I have a GeForce 8400M GS video card and am running Windows 7 Ultimate 64-bit. My laptop is an HP dv9500z (Product GP347AV). I am running an AMD Turion 64 X2 2.2 GHz processor.

I have an Acer Aspire 6920 with Windows 7 Ultimate 64bit and can not find the drivers (Even from Acer Website and Windows Update) For the following:
-Sim Card Reader
-Fingerprint Reader (and software)
-Media Control (Seems to work, but the volume does not follow the pad properly)
I have been on the Phone with Acer Support due to a battery problem (the battery is not charging) and they say it's due to Windows 7, as opposed to the battery being dead (I just received my laptop back from Acer repair due to the motherboard being dead, who knows how the handled the laptop, I obtainned it back with several deep dinks which where not there when it was shipped) so maybe I need the right driver for it to.
Acer wants me to reinstall their Vista OEM - not going to happen.

I recently did a clean install of windows 7 home premium (64 bit) on my notebook Hp Pavallion Dv6700z CTO. It came from Hp with Vista home premium (64 bit) installed. My processor is an AMD Turion 64 x2 Mobile technology TL-60 2.0 GHz (amd lists this as a dual core). It has 2.0 Gb ram w/ 64 bit OS. I am getting an error message which states...
Coprocessor-The drivers for this device are not installed. (Code 28). I tried to have windows resolve the issue but it could not locate any drivers.I tried Microsoft support but after almost 2 hours and many driver installs they say they cant find a solution and its Hp's fault for not supplying drivers. I went through Hp they but its my problem because they dont support any OS updates so any help would be apprecited.

I have an Acer Aspire 5720. It is not listed on Acer's website as compatible with Win 7, however many other models with the same specs are. I have been able to find drivers for most of the hardware. The only ones I cannot locate are a Windows 7 x64 driver for both the Alps Touchpad and the Bison Crystal Eye webcam. I am an adventurous one, and have a solid backup, so I am going to try it anyway. I was just looking for any assistance in locating those two drivers.

Sorry if I'm posting this in the wrong place, but any pointers would be hugely appreciated! I'm running an ACER Aspire 5920G laptop, which comes with Vista 32-bit installed. I'd really like to give the Windows 7 RC candidate a try, but don't want to screw anything up!
I'm going to add a new partition so I can dual-boot the existing OS with the new one, but my major concerns come from ensuring the hardware works acceptably. The graphics chipset in the 5920G is a Radeon 3470 HD Mobility, and I keep it up to date under Vista using the Mobility Modifier software. Will the same modified drivers work fine with Windows 7 RC? (I'm hoping that there might be someone on this board who's been in a similar position).
Also (and this isn't quite on the topic of drivers), the laptop has 4gb of RAM installed - is it worth using a 64-bit version of Windows 7 RC, or does that complicate matters unnecessarily?
