    I tried all the suggestions listed there and even went to the local registry to state some of the services. I also run Windows Update Assistant, still the problem was unresolved. Although I was able to solve a similar problem in Lenovo ThinkPad from the Bios but finding it difficult to solve same problem in Asus and Toshiba Satellite laptops
