I have purchased HP Compaq 610 and I have installed the windows 7and it is working absolutely fine. When u connect the internet using the cable at that time I donít face any problem but when I try to connect internet with my wireless internet connection at that time wireless button remain as it is . it does not change from grey to blue. I have tried so many time but it doesnít make any difference for me. I donít know what is going wrong with my laptop. Please help me to solve this problem it will be very helpful for me.
