Hi, i contacted the dlink helpdeskman. he asked me to boot the computer along with plugged usb adapter and asked me to ammyy.com to download, so that he could access my browser. i did and after verifying the presence of wifi thro his usb, he said that he will shut down my computer. i readily agreed and the computer shutdown without any hanging. So, he asked me to look for some other causes for this behaviour.
I have tried all the things, and found that this is the cause. when i not ejecting the usb adapter , it will not shutdown but hangs at shutting down process.
as seeing of doctor cures the patient in a way, the computer probably would have shut down. i suppose, there is no logic.
I have seen a film, where an auto driver start efforts would be nullified by two persons , by forcing the auto not to start from the back of the auto, and when the autodriver comes to look for possible reason, the person who stopped the auto, would voluntarily come for help and in a new way would adjust the view mirror of the auto of the other auto and ask the driver to start. It would start. the logic is such that , the autodriver tries to do the same thing when another auto fails to start, would give him doses from the fellowmen.
Ok fun apart, what would be the other issues. I fixed this issue, but the vendor would not accept, as when he analyses the problem could not occur.pl
