I have hp compaq 6720s laptop and it has Intel centrino 2.10 GHz T8100 processor. 3MB L2 cache, 3GB RAM. Means it is a solid machine specs wise. Isn't it? Now it often has the problem of Ethernet card and one more thing that I found today is its caps lock key don't give any onscreen notification for caps lock on or off however its light works that is on the button. Please tell me solution if anybody knows. Thanks.

It sound like drivers and software have been either disabled or corrupted. You need to go to the HP Compaq site and update all drivers and software.
