How can i update dell dock?

A docking station is an extension or addition of ports for a laptop computer. Once the portable computer is docked, you can access the docking station's ports, such as PS/2 or USB 2.0 ports, through your computer. Some docking stations have monitors that you can connect your computer to, placing your video on an external screen so you can turn off your computer's monitor and conserve some of your computer's energy. All Dell docking stations will have the same general troubleshooting steps.

Plug your laptop's power adapter into the docking station and dock your laptop onto/into the docking station. If there is no power going to your laptop from the docking station but it works when the power adapter is plugged into the wall, the docking station is bad and needs to be replaced. Plug your power adapter into the docking station and dock your laptop onto/into the docking station. If power goes on but your computer doesn't recognizes accessories such as a USB mouse--plugged into the docking station, try a different port on the station. If it works in a different port, the previous USB port is burned out. Plug your power adapter into the docking station and dock your laptop onto/into the docking station. If power is going through the docking station but no accessories are being recognized, you might have a corrupted docking profile. Undock the computer and dock it again once it has fully started up to reset the docking profile. Plug your power adapter into the docking station and dock your laptop onto/into the docking station. If you have an external monitor and it is not working, completely close the lid on the laptop so the image will move to the external monitor. Plug your power adapter into the docking station and dock your laptop onto/into the docking station. If power is going through the docking station but no accessories are being recognized and resetting the docking profile fails, update all drivers through Dell's support website and then re-dock the computer. Some of the software that runs the hardware may have become corrupted. Hope this helps

Problem with external monitor activating with DV6 1360-us

You can switch to an external monitor or data projector by two methods. 1. Connect the external monitor to the laptop's video port, power up the external monitor first and the laptop. The video information will automatically switch to the external monitor. 2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop. You can also toggle between the external monitor or both LCD screen plus the external monitor or back to LCD screen only by pressing the Fn key plus one of the function key a few times. Here is a list of key combinations for some of the laptops :- IBM ThinkPad = Fn + F7 HP and Compaq = Fn + F4 Toshiba = Fn + F5 Dell = Fn + F8

My screen goes dark when I use my laptop. I have a docking station with monitor and the machine works fine. However when I undock or start up with just the laptop the screen goes black. I can still see...

Hi wilhejl,

I see that you are experiencing a video issue with you back light on this case,
you mentioned when docked on your docking station you see the video on you monitor but when undocked you get a black LCD screen and see shadows of what is on the LCD screen.

this is a back light issue that you are experiencing.

We can try and check some settings regarding this concern and se if there is anything we can do to correct what you are experiencing with your laptop

As soon as you turn your Laptop on keep on tapping F1 to will bring you to the BIOS screen if the BIOS shows up on you LCD screen without going black then most probably yo may need to change some settings in windows regarding the the LCD and power options.

  • Try docking back into your docking station and inside windows go to power options, and set your system power options to balanced.
  • On your Desktop right click anywhere on an open space to get the menu list click on personalize then click on display then click on advance settings, look for screen refresh rate change it to 59Hrtz then undock from your docking station and try booting into windows without using the docking station to check if the video will show on the LCD again on this issue.
I hope that this can help regarding your case,

Have a nice day.

unplug everything from the docking station, and press and hold the power button for about 15 seconds. Afterwards, plug in only the power and the monitor to the docking station and dock the laptop (make sure the laptop is turned off before docking and turn on after docking). If you still have issues it could still be hardware or software at this point. If you do not have issues, plug in one thing at a time to the docking station (mouse, keyboard, ect.) and restart the laptop each time until the problem starts again. this is how you will know if a device in the DS is causing the issue. if your monitor is vga (port on back of docking station where monitor is plugged into is blue) try plugging it directly into the laptop. also try plugging in the keyboard and mouse directly into the laptop (if they are usb) and anything else you may have plugged into the DS. This will be a better way of testing your devices. If all devices work fine, i would say that it could be more of a hardware issue with your DS.

Dvi port doesn't work with 23'' samsung monitor

yeah, you can set the display setting as extension display your DVI

Intel, ATI,Nvidia have tools also to set up,

i have ATI and use the ATI Catalyst tools and autodetect the monitors that i connected to my docking station, intel and nvidia also have this utility.

it depends on setting if u wanted the external monitor as CLONE monitor of your laptop or extension Monitor...

or they might have problem on DVI port of your docking station.

download and install the video utility ( must have .net installed before you install the utility)

the utility will detect your video ports (VGA,DVI,S-video)

let me know the update ..

Inspiron 600m,"no input signal check video cable"?

Do you have an external monitor for use when the laptop is on the docking station? If so, does your laptops screen come on when it's not docked?

If you're using an external monitor while the laptop is docked, make sure that the screen selection is for external monitors, by pressing/hold the FN key and then press the F8 key to cycle through the choices between LCD, Monitor/LCD or Monitor only.

No Power,No Booting,...

try to visit

probable cause: there is an external device connected to your computer like printer, external hard drive or docking station. remove any if there is
could be a video card issue: try using an external monitor if you will get to see anything on it. if video card is integrated and you still have a warranty in your system have your motherboard replaced. when you use an external monitor be sure you know how to switch the screen from your lcd to the external monitor.

when you turn on the computer do you get to see anything come up on your screen before it goes blank?

try also removing the memory/ies of your system. see if you will get to see an error message on the screen and beeps from your computer without the memory. then try putting back 1 at a time and try using other memory slot to check if one of the slot is not working or just your memory

No ethernet with docking station

It could be the connector on the bottom of your laptop that's creating the problem. Does any other ports work on the docking station when docked?
