    Hi All... my problem with the display is solved.
    The laptops were still under warranty and the service centre is nearby. So, I took them to the service centre and since it's under warranty, they changed the ribbon cable free of charge. Both service and the ribbon cable. And both are working fine. But it took about a week to order the ribbon cables because they had to order from abroad. Lenovo service rocks. This I would like to add.

Sounds like you have a faulty ribbon cable or the ribbon cable it needs re-attaching to the motherboard.

    Hi, Chris. Thanks for the reply. That could be the problem. Which means I need to open up the cover(s). I have 2 laptops with the same problem. Will see how I can manage it. Thanks again.

SOURCE: Missing Docking Station key

You will have to take the docking station apart until you can see the locking mechanism. Once you can see the mechanism, you should be able to get a screwdriver ron it and release it. Make sure that it releases, don't force it, and most of all, be patient.

SOURCE: dvi port doesn't work with 23'' samsung monitor

6710b does not support DVI even though they never said so in the documentation, i'm betting that 6715b does not either. I'm pretty bummed about it. My nc6400 worked great, just switched to the 6710 and my dual monitors would not work, with a little research i found that the DVI on the docking station, simply is not supported. No matter what your monitor configuration is...Ctrl+Alt+Del to you too HP!

My asus universal 3.0 docking station will not show monitor with my ux32vd Zenbook


Ok It would help if you mentioned what operating system you have! Windows 7 or 8 or MAC
In windows go to display then resolution you will have a choice to duplicate displays or extend displays, make sure the external monitor is plugged in to the VGA or HDMI port.

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

I want to use a external monitor keyboard mouse and close the lid and keep working on the computer


I'm not sure if you'll be able to close the lid because you might need a laptop that is designed to work with a docking station to do that.

Anyway, you can hook an external monitor, usb keyboard, and usb mouse to the laptop and continue working as usual.

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.
