One trick is to go to the manufacturer's website and get a detailed list of all the hardware in the computer. Then go through Device Manager item by item and cross of the ones that are installed correctly. Whatever is left on your list after you're done is the unknown device. You can then get the proper driver(s) from the manufacturer.

With Netbooks, wireless network stuff, touchpads, USB hubs and IR stuff are the most common to have trouble with, assuming the things boots and does the basic stuff (sound, video, etc) all right.

Usually, when you buy any hardware the drivers come along with it on a disc. If you lose the driver disc you can always download the necessary drivers from the manufacturer's website. But what do you do when you are not sure of the manufacturer of the hardware?

Every device has a Vendor and Device id associated with it. If you can find this ID, you can find the manufacturer. In Windows it's easy to find the vendor and device id.

1. Open Device Manager (Control Panel>System>Hardware>Device Manager)
2. The hardware whose drivers are missing will appear as Unknown device, so it's easier to locate the device.
3. Right click on the unknown device and click on Properties.
4. Under the Properties window click on Details tab and select Device Instance Id from the drop down box.
5. You should see a code similar to this
   
   PCI\VEN_8086&DEV_27DC&SUBSYS_30868086
   &REV_01\4&1E46F438&0&40F0
   
6. The portion of the code highlighted in RED is the Vendor ID and the portion highlighted in GREEN is the Device ID. In this example:
   
   Vendor ID = 8086
   Device ID = 27DC
7. Once you have obtained both the IDs, proceed to PCI Database. There you can either search for the vendor from the vendor ID or directly get information about the device along with the vendor name by searching with the device ID.

Great isn't it? Now you will never have to go hunting for correct drivers.

ACPI should have something to do with the netbook battery controller.

The services.msc is "CmBatt", maybe check if its set to automatic & is started.

Did you try Unknown Device Identifier? (My post #5 above)

 

[Saba Zubadze]

Yes,but did not worked.

Here is what I did and it worked for me:

I have a Windows 7, 64 bit machine with an unknown driver ACPI\FnBT0000. I downloaded the file
"nb-driver-i1320-win7-64-configuration-center.zip"

It is available for download from here:
GIGABYTE I SERIES I1320 ? Descargar drivers @ PCDrivers.es

Once it downloaded, I unzipped the zip file (using 7 zip) and navigated to the folder:
\nb-driver-i1320-win7-64-configuration-center.zip\CC_x64\support\FN\Win7\

In the above folder, there is a file called "virkbd.inf". That is the driver for this.

==========

Manually install the above "virkbd.inf" driver file as follows:

Start Button -> Control Panel -> Hardware and Sound -> Device Manager -> right click on the unknown device -> Update Driver Software -> Browse My Computer for Driver Software -> Let me pick from a list of drivers on my computer -> Have Disk button -> Browse button -> find the "virkbd.inf" file and follow the prompts.

When you are done you should see "Virtual Keyboard Device" as a new, working device under "System Devices" category listed in Device Manager.
