I'm having HP Pavilion dv7-2173cl laptop on which i had installed Windows Vista as my operating system. Just few days back i had upgraded my Windows Vista to Windows 7. I had used Windows 7 upgrade disks from HP for the up gradation process. Overall I have no complaints, but above my laptops keyboard is a touch sensitive strip with volume control, movie controls, etc. Now the problem is when i try to turn on my volume, it shows as working whereas the volume on/off indicator can be seen in red. It states that the volume is turned off even tho my volumes on and fully functioning. So, can any one tell me that how can i resolve HP Pavilion dv7-2173cl Windows 7 issue? Any body knows about it? Kindly help me out to resolve the above issue. Thanks.
