The Unknown device problem solved

                      The Unknown device problem solved

The famous problem that every computer operator face is the "unknown device" problem. It appears when someone opens the device manager menu, a yellow color triangle with an exclamatory(!) mark appears in the sub-division of "other devices". All of us have had this problem at least once a while and it is really irritating. So here is the solution to the problem.

Steps

1.Right click on the unknown device and select properties.

2. Now select details from the dialog box.

 3.Now this is going to be the most important step. Inside the "Value" category, some alpha-numeric values will be written, like in my case, it was "ACPI\HPQ6001\2&DABA3FF&1". Now right click on this alpha numeric value and copy it, then open google.com and paste it in there. Now erase the numbers or alphabets written after the 2nd slash and keep the rest as it is. now erase the only slash left (i.e.only ACPI HPQ6001 should be left),then click on enter. 

4.The results will show your laptops/PC's website with the driver needed or some site where you can download the driver. Select any website and download the driver and install it. After restarting the computer, you will no more find this particular "unknown device.  

If you are still facing any problem with the drivers, do mention it in the comment.
