I have upgraded my Dell Studio 1558 laptop to Windows 8 Pro last week (fresh upgrade without keeping anything from previous OS). Microsoft has provided almost all essential drivers out of box, but not all. And, Dell is just not thinking about it anymore as the system is old. Now, I am stuck.
- Device Manager is displaying four
Unknown Devicesentry with yellow exclamation sign.
- Windows Action Center is suggesting to install drivers of sensor and card reader.
- I have installed driver of card reader from suggested link given by Action Center, but its not working.
- I am unable to use Bluetooth. It has not been detected by Action Center, too.
