Any of you guys savvy on laptop workings?
For years I have been using a Dell laptop and a separate Dell monitor. The are connected through a junction box which has the keyboard, mouse, audio, monitor connected to the laptop via a USB cable.
I would turn the monitor on then the laptop and after going through its motions both monitors would show the same screen. Then I would close the laptop and work from the stand alone monitor.
I have Norton security which has been working fine for years. Well I did some type of latest upgrade and then I couldn't get anything to work. You know you do the usual and turn off everything and reboot. Did that and the side monitor is no longer recognized. I can turn it on but it goes to sleep mode right away since there is no connection with a PC.
I checked the laptop's system where you note or connect a monitor. It cannot find it. nothing. Plugged , unplugged, turn off - on...nothing.
Its like the monitor isn't connected...but it is.
Any ideas?
