Hi All, I am using HP Pavillion dv3005tx. I am using this laptop since 2 years without much trouble. However recently there were few important updates that i downloaded and installed. After few days i shut down my computer to complete the installation. But now when i start my computer, i can only see light flashing at the front but I dont think my hard disk is working. So in short my computer does not start at all. Only lights flash at the front near keyboard but nothing is displayed on the screen nor is hard disk running. I tried to remove battery and start my computer with power cable but it still does not help. Please advice any quick solution. I need laptop for urgent use. Thank you.
