• S230u Windows 7 unknown device

  My company recently bought a ThinkPad S230u for use on the ground, time management and others, to help relieve the duties of our managers. However, my company only supports up to Windows 7, so it was my job to make this thing work on Windows 7. I managed to compile almost all drivers for the machine with hardware ID and various research, which I'll be happy to help provide if anyone needs them. However, there are still two items in my device manager I have not managed to solve yet, and I do not have any progress. Any help would be appreciated.

  Two unknown devices have hardware ID:

  ACPI\MSFT9000

  and

  ACPI\MSFT9001

  My guess is that it's the battery, but I already have the lenovo power management software installed with no luck. If anyone can help me to get it working on Windows 7 x 64 (Professional), I would be very grateful. Thank you!

  As a note, if anyone needs help for other drivers together for a similar project, I'd be happy to help you. I already did the work, so no need to repeat the process if you don't have to.

• XPS 15Z Windows 8 unknown device on PCI Express Root Complex

  Hi, I have a Dell XPS 15Z, which I bought off a friend. They have recently updated to Windows 8 and now, that's what I have. But when I go into my sound drivers telling me I have an unknown driver. some online solutions responded to my questions even though some came close. So, here's what I know:

  Unknown device

  Type of device: other devices

  Manufacturer: unknown

  Location: on PCI Express Root Complex

  Hardware ID:

  ACPI\VEN_SMO & DEV_8800

  ACPI\SMO8800

  * SMO8800

  I don't know if it's related, but my laptop also does not load. I just bought a new AC adapter to replace the one I had, and it is not yet supported. The light flashes red 4 - 5 times and blue/green once. Ive looked online to see what the problem is, but I can't do some of the patches that the computer is at 0% battery.

  The hardware ID, it is the free fall sensor:

• M18x R2 Windows 8 "unknown device".

  Hello everyone, I have an Alienware M18x R2, which displays "Unknown device" in Device Manager.

  Here are the specs:

  I7 3920

  32GB 1600 Mhz RAM

  2 x GTX 680's

  2 x 1 TB drive HARD Western Digital 5400 RPM

  1 x 60 GB OCZ mSATA HDD

  380 Bluetooth

  WiFi killer

  Win 8 Pro 64-bit

  This particular "unknown device" does not appear with a Windows 7 operating system

  If I use Windows seven and install all recommended drivers, there is no problem, the "unknown device" in question is not yet with Windows 7 running, I did a clean Windows 7 and verified installation each device ID in Device Manager before installing anything else to see if I could find the one causing problems in Windows 8 - this is no where

  As soon as I install Windows 8 and check Device Manager, then this particular "unknown device" appears again, even after the installation of all the drivers in Windows 8 recommended is the only 'unknown' on the left.

  I tried searching the Internet using the hardware vendor ID and the device ID provided in the details section of the "unknown device" but could not find an entry useful, even using the databases of the seller and the material has been a waste of time

  Here is the hardware device ID exactly as it appears, three lines altogether, but I think the top one is relevant.

  ACPI\VEN_DELL & DEV_ABCE

  ACPI\DELLABCE

  * DELLABCE

  Any help would be great.

  See you soon

  Hi, this is certainly the driver for switching to airplane Mode. I finally could get mine put to update the other day. If you let Windows search the best pilot, it can automatically find now, he appears to have done on my machine.

• 4 "other unknown devices" in Device Manager. Windows 7 RTM 64 dv7 1450

  Just bought a computer HP dv7-1450 laptop with AMD Turion X 2 64 processors. Installed Windows 7 RTM 64 and everything seems to work except there are 4 unknown "other devices" listed in Device Manager. The 4 devices are:

  -System base unit (x 3)

  -Unknown Device (x 1)

  I have no idea what are these devices. I tried looking for drivers for chipset on the AMD and HP Web site without result. But I do not know if these are the associated chipsets. One of the devices would be the disk fall sensor hard (it does not appear in the device no matter where Manager)?

  Unfortunately on the HP site, there are not many downloads of drivers available for the 64-bit (Vista). I know that Windows 7 64 drivers won't be available until in October, but if there are not any available Vista drivers either, I expect to see all the drivers for Windows 7?

  The most important thing for me is just to know what are these "other devices" 4 and get the drivers installed.

  Thanks in advance!

• Unknown devices in device Windows 7 Manager - dv7-2170us

  I have a laptop dv7-2170us.

  I did a clean install with Windows 7 Home Premium 64-bit.

  I used the drivers for this model of laptop on HP's site.

  I get a few unknown devices in Device Manager.

  I tried to uninstall the device and re - install to allow Windows to re - detect but no drivers are found.  See the pictures below, what devices could they maybe refer to?

  I have all the necessary drivers load that I know and I installed a driver who looked valid on the site of HP drivers.

  

  

  EDIT: Everything works!  Thanks for the tip of Daniel.  I googled how to identify the ID of material and is here with this site http://www.pcidatabase.com/ , punch in the device id and bam, it IS the card reader.  Weird because it worked perfectly.  But I downloaded the driver even re-installed and this solved the problem.

  =============================================

  I tried the Intel Chipset utility, did not work. However, here is the hardware id:

  

  

  

  If you look closely, you will notice that each of these devices are in fact different.
