Question about Dell Computers & Internet
Plug the adapter into the wall outlet or power strip. If using a power strip, make sure the strip is on. Most laptop power adapters have a small LED light; the light will illuminate when power is being transferred from the outlet to the adapter. If the light illuminates, chances are you have sufficient power to supply your laptop. Wiggle the power cord if the LED light did not initially illuminate. If the light turns on and off when you wiggle it, you might have a loose cord in the adapter, or the outlet could be faulty. Plug the adapter into another power outlet, preferably a different circuit in another room, if the LED light did not illuminate the first time. If it lights up from the second outlet, the first outlet either does not work or other devices were using too much power on the initial circuit. Connect the other end of the adapter to the laptop and turn the laptop on. When the computer starts up, you should see an indication of how the laptop is being powered in the lower right-hand corner. If you see a battery icon, then the laptop is being powered by the battery, not the adapter. Make sure both ends of the adapter are securely connected. If they are, and if the LED light on the adapter is lit, then you likely have a faulty wire that is not properly connecting to your computer. If you see a plug or adapter icon, then the laptop is successfully being powered by the adapter. If the LED light on the adapter is not lit, then the bulb is out, but the adapter is still working.

Could be one of two things the adapter that you are using is not rated for your laptop or you have a loose power port .if you have a test meter set it for 20 volt dc touch the the silver outside contact with the black ground probe and the inside contact with the red positive probe the voltage should match what is labled on the adapter.if not you may have a faulty adapter .if the power port is loose you will have all kind of problem like starting and shuting down after 10 to 20 secounds or blue screen and serious error meassage and the board getting hot and failure .

as long that driver already installed go to control panel and open scanners and camera, if not work go back to bios and select factory default.

hi...volume wide open but no sound,, check your setting configuration on your setting control panel and look for sound & audio device, also check... control panel system see if you dont have any yellow mark indicate missing drivers, if yes... re-install your sound drivers from your CD-recovery if you have one, if you dont have one, you may have to look on exemple.... dell.com and look for drivers & update
