I am using another laptop, whilst mine is away for repair, had to send it back to the manufacturers, couldn't ask you, as was unable to get on line. See if you can fathom it out, I could send & receive emails [Outlook Express] & my AV could download updates, but no way could I use Internet Explorer, either by icon or hotkey, neither could I get to a website via an address shown on an email. I did get an expert in IT to look at it, [12 years experience] here at my home, he struggled for nearly an hour, then took it away to his workshop,....still no luck, so he, as I said, has sent it back to it's source. I'm not trying to outguess him, or the manufacturers, but your views on this will be very interesting, especially if they cannot repair/correct the fault, you've done it before!!
