Unable to turn off screen after docking Latitude E7440 to E-Port II docking station

Q: Unable to turn off screen after docking Latitude E7440 to E-Port II docking station

I have a Latitude E7740 that runs Ubuntu Xenial (16.04). I dock it to a "Dell EURO2 Advanced E-port II" docking station.
If I boot it in the docking station, everything works fine, and I find all my two DVI-connected monitors.
However, if I undock, then put it into the dock again while running, it fails to enable the screens. I'm using a script called autorandr for switching between display modes - it uses xrandr. It tries to run:
xrandr --output DP1-1 --gamma 1.0:1.0:1.0 --mode 1920x1200 --panning 0x0 --pos 0x0 --rate 59.95 --reflect normal --rotate normal --output DP1-2 --gamma 1.0:1.0:1.0 --mode 1920x1200 --panning 0x0 --pos 1920x0 --rate 59.95 --reflect normal --rotate normal
But the X server responds with:
X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 21 (RRSetCrtcConfig) Serial number of failed request: 48 Current serial number in output stream: 48
Running this exact command after booting in the dock is doing the right thing, but after undocking then docking, it doesn't work.
Any ideas here? I have updated to the latest BIOS version.
Problem also reported in launchpad with lot's of debug info, here:
Autorandr script is here: github.com/.../

Preferred Solution: Unable to turn off screen after docking Latitude E7440 to E-Port II docking station

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


I attached my laptop to an older docking station and now cannot get it to release. There is space between the laptop and the release box. Any suggestions to unlock it?

We have around 100x E7440's and on most of them we have the same problem. 
When the machine is operated on battery then the lid is closed it goes to standby/hibernation (this is not the problem).
But when the machine is docked into the port replicator / docking station and switched on, as soon as Windows starts, it goes to Blue Screen.
OS: Windows 7 Enterprise 64 bit.

Hello -  My x220 does not lock into  Mini Docking Station Series 3 that I bough recently. The rubber pads on the battery seem to be preventing the laptop from being docked.

all I got a new E6410 and 2 docking stations around a month ago.
The problem I have is that when the notebook is in my office docking station it is really really slow.
I can watch while window contents are draw, switching messages inthugnerbird takes a couple of seconds.
In the home dokcing station everything is fine.
Can anyone give me a hint what I can do about.
I'm planning on calling dell support, but I guess they'll be pretty sceptical.

A:Latitude E6410 slow when in docking station

it may be taking forever trying to access network shares which are available at home but not at work.
I suggest swapping the two docking stations. If the same docking station has the same performance, then the one which causes slow performance is defective in some way. If the laptop is still slow at work and fast at home, then the problem is caused by there being something different about the environment.

Hey guys,
I have a latitude e7450 on a Dell E-Port Replicator Docking Station with USB 3.0, with an external monitor attached to the docking station.
When I boot up the laptop with the lid closed on the docking station, if freezes on the "dell" logo,
and does not get pass that to the windows welcome screen. I tried using the power button on the docking station to no avail. So I have to open the lid whenever I power up the system and it's really frustrating.
Is there a fix to this or is the system rigged to not boot up to windows whenever the lid is closed?

Thank you

Hello there,
I dont really belive that anyone is abble to help me fix this problem but ill give it a shot coz this is reallt weaird and annoying.
So i am using an docking station to my dell, it has 5 USB ports (3 on the left and 2 on the back).
Now i am using a logitech wireless mouse. Whenever i plug the usb mouse receiver to any of the left ports, it works just fine. If I use any of the 2 on the back, it lags as hell and it seem to get stuck in every procces action, like moving files over explorer etc.
But thats not the most anyoing thing im expiriencing...
I wanted to make my life esier, so i bought a mini-pcie usb adapter, this one: 

And i plugged my mouse receiver to it- it works great! BUT WAIT, only if laptop is not connected to the docking station! If it is, im getting the exact same problem as i would connect the mouse receiver to the back of the docking station...
I tried reinstalling the root usb hubs but it havent changed anything. This is weird as hell.
I would really aprichiate if someone could help me with this problem. rly.

A:Latitude E6520 Docking station USB problem

I fixed the problem, im not sure if this was the cause, but lemme show what i did:
So at the start, please look at this picture:

The way those 2 slots are populated is not natural- what i mean is that at the beggining i only had the wan card and one slot was free. But, before installing the usb dongle with its card i had to move the wan card from wan slot to sataflash slot and insert the usb dongle into wan slot. Why? See the place i circles (squared?) with red color. This metal border was to close and the dongle was to long so it wouldnt fit.
This way it was buggish and when i turned the switch my mouse wasnt working instead of wireless...
What i did to fix this problem:
I ripped off some of the metal borded using sharp pliers and replaced the cards to the proper slots (wan card in wan slot, usbdongle in sataflash slot).
Everything seems to be working so far.

I am trying to connect 3 monitors to my Latitude 5480 when hooked to a K17A docking station.
I have one hooked up DP, one VGA and the other HDMI but the 3rd monitor will not work.
It appears that the Intel 520 supports 3 monitors and from what I read, it looks like the K17A should be able to support 1 analog and 2 digital but I simply cannot get this working.

Running 2 external monitors ( LG-34UC87C-B)

HDMI 1 @ 2560x1440 ( I cannot reach this, I can only get 2560x1080..?)
HDM 2 is not used
Running the HDMI @ 2560x1080 just looks horrible, how can I achive the 2560x1440 that this device states it can handle?
If the D3100 cannot handle what I require does Dell make a Docking station for the 7370 that will handle idealy 3440x1440 x2? either HDMI or DisplayPort.

When the laptop is plugged into the docking station headphones won't work, regardless of whether I plug them into the laptop or the docking station.  This means that every time I want to make a Skype call, for example, I have to disconnect from the docking station and plug the headphones into the laptop.  Any one have any suggestions?

A:Latitude E5550 - headphones won't work when laptop is plugged into docking station

Is the headset being detected at all by the notebook when detected? Right click on the speaker icon on the task bar and choose playback devices, are the headphones listed? If they are listed click on it and then click the configure button to bring up speaker setup. Click the test button and do you get the test chimes via the headset?
If you did hear the test chimes then the headset is working fine.   Clicking cancel should return you back to sound properties. Make sure that headphone is still selected and then click the “Set Default” button. This should but the green “default” checkmark icon on the headphones now. Test to see if the headset is working correctly now.
If you continue to have problems please reply back with the model of docking station and headphones that are being used. Please also include if the headphones have an analog connection (headphone jack) or are USB. Please also include the version of Windows on the system.

              We bought Dell docking stations D3100 to go with our Dell Latitude E7450.
I’m trying to configure the laptop for when the user disconnect it from the docking station, it automatically connect back to the network Wi-Fi.
Adapter Switching work great if I use the Ethernet adapter on the laptop itself. Once I disconnect the Network cable, it looks for the Wi-Fi and connects to it with no issue.
If I connect the network cable to the docking station, once I remove the connection from the docking to the laptop(usb3), I lose the wired network and it’s not even looking for the Wi-Fi.
I did configure the Dell gigabyte adapter on the docking station to be the first priority over the Wi-Fi just like I did for the laptop network adapter.
I updated the bios, firmware and drivers.
I also looked at the bios power management: Wireless Radio Control settings
Both local area network connections are above the Wireless one (priority)
Both Local area network adapter metric are set to 10 (only 1 is in use, both are set for testing purpose) while the wireless adapter metric is set to 9999.
As anyone had this issue or was able to get this working? Am I missing something ?

Hello,I am using the Lenovo Thinkpad P50 with the 230W Lenovo docking station, with the latest BIOS (1.59) and all Lenovo driver updates. It runs Windows 10 Pro v1903, has 40GB RAM, Intel i7 @ 2.7GHz, Nvidia Quadro M1000M. The problem: Fan (even on low CPU loads) never turns off (and the noise is getting on my nerves). I have read a number of forum posts here, some of which speak of BIOS updates and firmware updates for the docking station, but none seem to apply.Changing the Windows Power Options (Processor management > System cooling policy > Plugged in) from passive to active makes no difference. What must be done so that the fan turns off on low CPU use?Thank you in advance for competent hints and guidance in solving this.

I have a Toshiba Tecra M11-17V laptop, which I frequently use with the docking station that came with it.
There is a DB9 serial port on the back of the docking station but I do not know what COM Port it is.

I am using Windows 7.

In Device Manager, COM9 - COM22 are identified as BT Port (bluetooth). COM7 - COM8 are RIM Virtual Serial Port v2, COM17 is Prolific USB-to-Serial Comm Port and COM18 is USB-Serial CH340.

I figured that COM17 or COM18 were the most likely candidates, but have not been able to get it to respond using either of them.

I am connecting a Psion 5 (Comms app) to it, and have set the ports and the Psion to 19200 baud, 8bits, 1 stop bit, no parity.

I am trying to build the following setup:
1) Asus laptop (TUF gaming series FX504 with 1 hdmi port), Windows 10
1) 2 or 3 high resolution external monitors connected to laptop via a docking station
3) Multiple peripherals like keyboard, mouse, speakers etc.

I did a lot of research about docking stations to buy but I can't seem to find the one that I need. The things that I would like my docking stations to support are:
1) 2 or 3 external monitors
2) many usb ports
3) high performance

I am also not sure about the performance between docking stations that connect to the laptop via USB vs docking stations that connect directly to laptop ports, is there a performance difference? Am I confusing the port replicator with the docking station here?

I am also confused about the hdmi, vga and other graphical ports. My laptop has only 1 hdmi port so what's the appropriate docking station to buy and can I for example connect external monitors with graphical ports other than hdmi to the docking station and then connect the docking station to the laptop's hdmi or usb if it's a docking station that connects to the laptop via usb?

I would also like to just use the external monitors and not use the laptop display. Some people on the forums say that this can be done by changing the power settings - set "Choose what closing the lid does" to not sleep or shut down the laptop while the lid is closed and instead leave it running. Is this correct?

Hi All, I have a brand new Elitebook 850g3 (T9X36EA), a HP Slimline dock (D9Y32ET)  and two Dell P2415Qb 24" monitors. My aim is to extend my desktop to the two external Dell monitors  whiclst still viewing the display on the EliteBook. The monitors are DP monitors with MST technology so am able to set one as a primary and one as a secondary. I can achieve my goal simply when the laptop is off the dock (See image)But on the dock I get nowhere with it. I noticed the dock had a firmware update on the drivers page which specifically talks about the DP functionality, but on running the update it tells me I am already running at the latest FW version on the dock. At best, I can extend my desktop to one Dell monitor which duplicates to the other. I know my cabling is setup correctly and that the equipment is ok as it works off the dock, I have been banging my head for a while now, so any help would be really appreciated. ThanksPaul

I have a brand new Latitude E7470 that I'm trying to connect to a 4k monitor thorough an E-port plus II docking station. Unfortunately the image keeps blanking out on the monitor, at a variable rate between once a second and once every few seconds. I've tried both a displayport cable and a DVI-to-HDMI cable for the connection, and the result was the same. Changing the resolution did not help either.
I am running the latest BIOS and latest Intel graphics driver from the dell support page (both about a week old). (By the way, the BIOS update messes up the OS installation - buyer beware.)
I've tried many other combinations to trouble-shoot the issue:
1. Different laptops (E64xx), same E-port, same monitor -> works fine
2. Same E7470, different E-port (old USB 2.0), same monitor -> monitor blinks
3. Same E7470, same E-port, different brand 4k monitor, different DP cable -> monitor blinks
4. Same E7470, same E-port, monitor switched to DP 1.1 -> monitor stays black
5. Direct connection between the E7470 and the monitor via HDMI -> works (but only at 30 Hz due to HDMI limitation)
So the conclusion is that the combination of E7470 + E-port + 4k monitor doesn't work, regardless of the exact monitor or exact E-port. That leaves the E7470 as the only logical culprit.
Is this problem a design limitation of the E7470, a known driver issue or a faulty notebook?
Thanks in advance!

A:Latitude E7470 produces flashing/blinking image on 4k monitor connected to docking station

I am also having a similar problem with my 7470. Newest bios and drivers are installed. Happens on both the laptop's screen and using an external monitor through a docking station.
Seems to start after the monitor has been turned off due to PC activity. Can fix it with a restart OR by changing the resolution and changing it back. Both highly annoying options. Switching from external to laptop screen does not fix it, it will continue.
my external screen is using a DVI connection from the dock to the monitor which is also DVI so I am not using some kind of adapter. Removing the connection from my KVM does not resolve the issue either.

Hi Guys,
I just bought a Latitude e7450 and I am trying to use it with my PRO3X e-port docking.
I have found some issues but the most annoying one so far is the imposibility of using the Power button on the dock to start the laptop. The Power button is blinking (blue) but I cannot use it to power up or power down the laptop.
Am I missing any setting on my laptop? Is there a problem with my laptop? The docking worked fine for the past 4 years with my Latitude 6320 so I suspect there is nothing wrong with the docking.
I have installed the latest BIOS update today.
Thank you in advance for any suggestion.

I have just bought a Dell XPS 15 (9560) and a Dell WD15 docking station with 130W power brick (same wattage as the laptop's AC-adapter). When I only use the docking station to power the laptop the discrete graphics card (GTX 1050) does not seem to work. When I am in a game (eg. Starcraft 2), I get like 15 fps with the NVIDIA recommended settings. Then when I plug in the laptops's own power brick (while still in the game) I get an immediate four-fold increase in framerate. When I unplug the laptop's own power brick the framerate drops down to 15 fps again in a heartbeat. Furthermore, when I only power the laptop through the docking station, I cannot even find the discrete GPU in the list when I'm trying to run the Geekbench 4 compute benchmark (OpenCL). Only the integrated graphics shows up. When I plug in laptop's power brick I find GTX 1050 in the list.
I have run the Dell Command Update application and all my drivers and firmware are up to date. 
Does anyone have any idea to what the problem could be?

The newer Dell laptops (the Precision 7510, for example) have the bottom dock connectors very close to the back edge of the body, so that when you connect to them you have this huge gap at the back even if you slide the little dealy forward that is meant to account for different battery sizes. Yes, I know you can get this plastic spacer to fit in the gap so it is easier to line up, but the way it fits makes it take up a stupid amount of space.
Is there a Dell port replicator that actually has the connectors close to the back so that it doesn't waste all this desk space?
And, yes, I know that they make port replicators that the laptop doesn't sit on, that use the thunderbolt or usb port instead of the dock connector on the bottom. I'm asking specifically about port replicators that use that bottom connector.)
And BTW, Dell, it really doesn't help that you try to hide this by offering one photo of most of these replicators taken at an angle where it's really hard to judge that space.

blackbrook,Below is a link to our Dell port replicators and docking stations. You will need to chat to the sales person for more information. Also, is a post from a user on the DCF with the same system. He was issues an E-Port plus II.Dell Sales http://dell.to/2hBxzd9Quote from DCF Forum User-GeoDosch2"At work my laptop was upgraded to a Precision 7510. With it I got an E-Port Plus II docking station, which was basically the same as the one I had for my Dell Latitude E6520, except wider. It's a stretch to say that the laptop fits this port expander. Yes, you can connect it, but it's like putting a 5 year old kid in a 42 large suit-- he can get into it, but it certainly doesn't fit.I told our procurement dept. that they gave me the wrong port expander, though from the answers here it seems that Dell doesn't make one to fit this laptop. Is that something that's coming out soon? Or am I stuck with the kludge I have now"

Please help. I have Lenovo Thinkpad X61T. Everytime I docked my notebook I need to restart it before it detects the usb ports (I'm using an external monitor with keyboard and mouse attached on the docking station). I have updated bios but problem still persist. Please help. Thank you...

A:Unable to detect USB ports on the docking station

Your problem relates to Windows "Plug and Play". Specifically, it's called "hot docking". .

In order for hot docking to work as a Plug and Play event, several things must be in place and supported by both your hardware and software.

First off you mention a Thinkpad X61T. Is that a X61 Tablet???? Their site only lists X61, X61 Tablet and X61s.

What Windows operating system (I'll guess at XP Professional) and what Service Pack level?

And what is the version number of the "latest BIOS" you have installed.

Tell me if XP is running in ACPI mode
- click Start->Run, enter devmgmt.msc
- Look for Computer and double click it to expand it.
- Does it say "Advanced Configuration and Power Interface (ACPI) PC"? If not, exactly what does it say?

Hello, does anybody know if ThinkPad Thunderbolt 3 Dock is compatible with T480s? I have installed all the drivers  https://pcsupport.lenovo.com/ie/en/products/accessory/docks/thinkpad-thunderbolt-3-dock/40ac/40ac013... I have searched this forums and followed some advice re BIOS settings for TB3 (didn't make any difference). Everytime I connect this dock the mesage comes up "Display connection may be limited".All it does it charges the laptop, but no USB devices work (mouse, keyboard), also Monitor connected through display port does not work. I replugged and restarted everything multiple times. I also updated all possible drivers for T80s (Win10 x64). Any ideas how to get this working, or are those products not compatible? Many thanks for assistance

I have a HP 6530b Laptop, and on-board Broadcom NetLink Gigabit Ethernet adapter.
When I remove my laptop from the docking station, I obviously lose Network connectivity, however, when I replace the laptop back (or even just plug in a cable directly), I cannot reconnect to the network until I reboot.
I've had this problem for about 2 years now, and finally decided to try and fix it.
I've googled it and searched on here, but without luck.

When I open Network and Sharing Center (Win7), and click change adapter settings the adapter is missing from the list (after i have removed laptop from docking station).

Can anyone please assist?


A:Unable to reconnect to Network after removing and returning to Docking Station

Some kind of lack of communication among PC, docking station and router I suppose. Let's see if we can find any hints in the following. Show an ipconfig /all for when you are docked with connection, un-docked, and then re-docked before a reboot. After the last one try

ipconfig /release
ipconfig /renew

to see if that will get you going w/o a reboot.

Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)

Type the following command:


[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If necessary use a text file and removable media to copy the results to a computer with internet access.

I have ThinkPad T470 laptop with Windows 10 pro x64 installed. Sound plays just fine from the laptop's speakers, and when I plug external speakers into the laptop's 3.5mm audio port they work just fine too.But...when the laptop is docked in my Ultra Dock 90W docking station and the external speakers cable is plugged into the dock's audio port, no sound is heard. If I'm playing music through the laptop's speakers, as soon as I plug a cable into the dock's audio port no sound is heard. I can still use the laptop's audio port to connect external speakers, but that defeats the object of having an audio port on the Ultra Dock. I believe the driver of external speaker plugged into dock is well-installed and well-detected by the device managerI already set it as default audio output and can see the volume symbol up-and-down while testing it.I also had my T450 docked and the audio port from this Ultra Dock worked just as expected!! It seems everything works fine but still no sound can be heard when T470 is docked.Is it a bug when using Dock with T470 docked ??What do I need to do to get the Ultra Dock's audio port working?Anyone can help ?? Thanks a lot in advance!Kind regards,Jimmy

When I start my laptop or login to my laptop in docking station, the laptop screen often remains black. Appearantly it is sending the screen signal to the tv only. The tv is connected with an active 4k display port to hdmi adapter to the docking station. Windows key + p does not help. When taking the laptop out of the docking station, or, when disconnecting the display port plug from the docking station, there is no issue.Is there a way to set this up ensuring that the laptop always shows at least its own screen? I use the tv connection less often. I prefer not to have to plug in the display port for use. many thanks for your help!
