Hi, I have a HP Pavilion Entertainment PC Model dv6 laptop that I use at two locations ie work and home. I can shutdown the computer at home without problem but at work it refuses to shutdown. I have had the computer back to HP three times and there is nothing physically wrong with the computer. It has been totally restored to factory settings twice but the problem remains. I believe it is a wireless or network issue (I connect wirelessly at both locations and we also have a local area network at work) but cannot put a finger on the problem. I am pretty sure it is trying to look for something to closedown at the work site, hence the hang, that it doesn't need to look for at home. No other computers have the problem at either site but this is the only one using Windows 7. Any suggestions will be most appreciated.
