T540p - when undocking internal display unusable

Q: T540p - when undocking internal display unusable

Hi community, we are using several Thinkpads for years mostly without issues. But for a while now we have to experience issues with our T540p's in combination with pro and ultimate docks. And lately we also run into the same issue with a T570.Here our configuration, there are two external displays connected to the docking and one of them is the primary screen.And this is the issue: When we undock the T540p, the internal display should switch to be the primary and only display, but it doesn't. It seems to be that the T540p is still thinking to have external displays connected. The internal display is all black but I can move the mouse pointer from the right into the screen and can also move it out of the screen by pulling it downwards.All windows are opened on the virtual screen,which means I cannot see any configuration windows to change display behavior. Pressing Fn+F7 and up or down arrow blind does not change anything.It does not matter if I undock the T540p while it is running, or if I shutdown the system before undocking. When this error occurs it also does not matter if I connect an external display to the T540p directly, I still cannot see anything. To set the internal display to be the main display before undocking does not change the behavior anyway.If I put the T540p into the docking again, mostly everything is fine. The two external displays are running as before. If it was a desktop PC that would be fine but it is a notebook and we need to carry it with us and we need to connect a projector to it from time to time, so what do we have to do to get the machines running as expected ? Has anyone a solution to this issue ? Thanks in advanceThomas P.s. sorry for my bad English but I hope I am understandable enough.

My internal display just stopped working for no reason with Windows 10. The external monitor still works fine though.I checked the Device manager, the internal display had disappeared from the Monitors section, only my external monitor was listed there.It had happened twice. I brought the display back the 1st time after I uninstall the monitor driver and re-installed the latest driver from Lenovo website, but this time it's already with the latest driver and the same trick did not work.Luckily I still have a clone image of the system with Windows 8.1. Once I switched back to Windows 8.1 the internal display worked fine so I think it has to be a driver issue.The display adpater is Intel HD 4600. The internal monitor is the original HD display that came with the laptop. Please help.

I have a T540p that I am having unusual issues with the internal mike with.  It first showed up when attempting to use Skype and the internal mike would not pick up my voice.  All settings, both Lenovo and Skype, were checked and are set to the recommended ones.  In the course of troubleshooting this with the Skype audio panel open, I noticed that if I ran my finger across the top of the screen border where the camera and mike pickup are located, the Skype sound bar (green bars) would enlarge to the right as if it were picking up sound OK, but when I would use my voice, nothing moved on the Skype sound bar.
 
When I have the Windows sound app open, I can also see green bars appear on the mike indicator when I speak, but again, nothing seems to go out that is picked up by the mike.
 
Any ideas to resolve this would be welcomed.

Hi All, I have a T440s in an Ultradock with the monitor closed and three external monitors connected (1 HDMI, 1 DVI, 1 VGA). Everytime that i undock the laptop and open the display, the display stays black.  This doesn't seem to happen if i put the laptop to Sleep, undock the laptop, and then turn the machine back on.  The only solution after undocked is to do a hard shut-off (losing any open data) and then turn the laptop back on. I've used the Lenovo Updates and Drivers application as well as the support website to validate that the Intel HD Graphics drivers are on the latest version. Any help is appreciated!

Hi guys! I'm really having a bad time, my laptop is currently unusable since the backlight is not working on either the TN panel or IPS panel that I have for it. when I first got the laptop it worked fine, allthough it ran a bit hot 65c idle. So I decided to change the thermal paste for with some Arctic Silver MX-4 and the idle temps dropped to 43c idle, a very nice improvement if you ask me. Then I decided to change the awful TN panel that it came with since I've done that a thousand times before with other laptops, so I went ahead and ordered one from eBay (it came from UK) since I did not want to risk some china panel potentially breaking my precious new laptop. when I got the new panel, I turned off the laptop then removed the battery and pressed the power button for 30 seconds, then porceeded to take the bezel off and remove the "old" working display and install the new display. No problem.... or so i thought... There was only a black screen when i booted it back up!turns out that the backlight was not working (I was shining with a flashlight and getting a picture on the monitor itself)I then did the same procedure and replaced the "new" monitor(IPS) with the "old"(TN) still no backlight...

Hi,I'm having some trouble with the t540p in the UltraDock. I have a setup with 3 displays:- internal- external on DVI- external on DisplayPortThe external ones are connected to the UltraDock. I've got the problem, that the external monitor on the DVI-Port blanks frequently (about every 15min) for 2-3 seconds.Less frequently (about once every 1-2 hours) all external Monitors blank for about 5-10 seconds and you can hear in the speakers the Windows sound for disconnecting and reconnecting devices. Another abnormality I discoverd is, that when I use the t540p without the Dockingstation (but a power supply connected) the screen dims down to "battery level" from time to time (also only for some seconds) and the Battery-Symbol changes from "mains operation" to "battery operation" while the brightness is dimmed.This happens with both power supplies (the one shipped with the t540p and the one shipped with the UltraDock) Maybe these effects could be related somehow?Does any of you experience the same issues or has got any clue what could be the problem here? Best Regards,Andre

In the last week or so (can't remember last time I used the calculator, but about that time span) my calculator has serious display issues.

The display is cropped and also doesn't get invalidated (if I press clear). I can drag it off screen and it will invalidate.

The machine took updates from MS sometime between me using the calculator normally and now but I couldn't find anything in the update history that seemed to have any bearing on this issue.

Sounds like something related to Windows Themes. Right click on the desktop, choose Personalize and then select a Aero theme. See if that cures it.

Hello SMAGThanks for using the Lenovo forums.Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.(If the battery is internal, please just skip the remove/replace battery steps.)1. Turn the unit off2. Remove the battery and the Mains adapter3. Press and hold the front power button for 30 seconds4. Replace the battery and the Mains adapter5. Turn the unit on as normal If you`re able to, try to download the Video and Chipset drivers for the unit from the support page.
See if this will make any difference.

I currently only have one external display using the display port and I want to get a 2nd external monitor but I'm not sure if I can.

I have a Toshiba satellite a500.

The display stopped working about a week ago, and had not shown any previous signs of failing before then. I simply shut it down, and the next time it turned it on the screen had no display.

It can't detect it's LCD screen in any display options, and all brightness options have disappeared, as if it doesn't exist at all. There's no display on the screen, but other than that it still runs normally. For now, the laptop is only detecting the external monitor I have connected, which it designates as the primary display, rather than a secondary one.

However, I'm positive that it's not a hardware failure (for a weird reason I won't go into..), any advice on how to fix this, assuming that the problem is that the laptop isn't detecting the internal display? ( and not that it's a loose cable or a faulty screen..)

Thanks.

Hey guys, so i'm running B10074 on my laptop , and I connected my external display to it as well as my external keyboard and mouse at my desk so I could sit there and do the setup etc without moving all of that out of the way. I had the laptop lid shut and off to the side while I was doing this. Then, I shut the laptop down, unplugged all the external peripherals, and turned it on again. It went through the windows boot sequence with the spinning circles, then black screen. After 20 minutes of frustration, I realised that the laptop would show a login prompt only when I plug in the external monitor BEFORE i start it, and only if the laptop is closed while it is booting (when the lid is closed during boot, the Dell logo and spinning circles come up on the external display)

I further figured out that in Control Panel, it only displays the external display, its like the computer doesn't even recognise the internal display anymore. I dont know why that would be since when I first booted it up and installed drivers, I was using the internal display and everything was working fine.
Any help appreciated as well as pointers on not running into this again

Hi Everyone:

So I want to set my Yoga 2 Pro QHD+ (3200x1800) screen to 2560x1440 and am having some issues. windows will let me use for 16:9 3200x1800, 2048x1152, and 1080p. Trying to set a custom resolution in intel control panel gives me an exceeded bandwidth message with the HD 4400. I am using drivers 15.36.19.4170 and I have researched the issue but they always seem to point to using the hdmi out for a dual-link dvi display. One person on superuser had a similar question but I don't think it had a solution that worked I could follow. Can't create custom resolution using intel custom mode app in windows 8.1 - Super User

So does anyone know of a regedit to make this work or if my display can not support this resolution since the way the pixels are laid out or something. I think 3200 is to much for this gpu to handle well but love the real estate, and 2560x1440 is I think the sweet spot for 13 inch displays atm. My desktop res is also this resolution so I feel right at home.

Thanks again

Hi, My Thinkpad Twist does not display anything when turned on except on external monitors. The Device manager shows a greyed out internal display icon, says it is not connected. 1. Could this be the power connect ribbon cable p/n DC002C003W00 have a fractured wire(s)? I have tested for open circuit between PWR1 and PWR2 connectors and there are 4 sequential pins which are open circuit. Is this normal? 2. The touch screen works 3. There appears to be absolutely no LED backlighting working 4. Is there a possible fix for this and if so is it the power cables or some physical problem with the ribbon cables OR is it definitely a new display that is needed using existing cables? Thanks in advance Andrew

A:Thinkpad Twist s230U no internal display, works on...

The last 4 pins on the connector are unused I have determined so it is not the power ribbon cable connector. I found two wires fractured in the LCD ribbon cable right at the point where it feeds through the twist mount. I expect this could be a common problem after use. After repairing these two wires it did not fix the screen problem. I have ordered a replacement LDVS ribbon cable and will report back once I have replaced that.

I have a 9360 with the 3200x1800 touch screen and 16 GB of RAM.
When I connect an external 4K monitor and also use the internal laptop monitor, the external monitor flickers on and off every few seconds whenever the laptop is doing something graphically intensive (just zooming in and out of google maps is sufficient to trigger it, but lots of other things can too).
So far, I have tried two different 4K monitors, two different 9360 laptops, two different docks, connected directly to the laptop w/o the dock, a bunch of cables, and different intel graphics driver versions.  Currently running the Dell driver (21.20.16.4664) but they all have the same problem.
I can avoid the flickering if I disable the internal laptop screen when using the external screen - but that's not exactly optimal -  I'd love to be able to run both simultaneously.  I can also avoid it if I use a lower resolution monitor, but, according to the specifications, this laptop should be able to run 2 4K external monitors at 60 Hz simultaneously, and here it is choking on one + the internal display which isn't even 4K!
Has anyone else experienced this problem?

My Thinkpad Yoga 15 has a problem, which may or may not be related to the BIOS update recently performed. When booting, the bootup screen only appears on an external monitor via the HDMI output. When performing the hardware tests in the BIOS, tests are done on the HDMI-connected display, the internal display does not seem to be recognized. I verified this using both Linux and Windows. It does not seem to be a hardware failure; I have been able to get the display on the internal LCD a few times, by powering down the laptop, holding the power button for about 20 seconds, then powering back on while pressing F1. The laptop will then function for a while, but loses its display after coming out of sleep. Needless to say, this is unworkable. Does anyone have any tips on how this could be fixed in a more permanent fashion or any indication to cause? BIOS does not allow me to turn off NVIDIA, or its opposite, to enable it exclusively. I also tried different drivers, from both Lenovo as well as NVIDIA and Intel, but to no avail. Any pointers appreciated.

Hello,

I have had this problem with both the RC and the RTM builds of Windows 7 Ultimate x86 on two different Dell laptops--a Latitude D830 and a Latitude E6500. Both are running nvidia Quadro display adapters (the D830 is a Quadro NVS 140M and the E6500 is a Quadro NVS 160M). In the case of the D830 I am running the latest drivers from nvidia's site (Dell didn't post Win7-specific drivers for this laptop). For the E6500 Dell has posted Win7-compatible drivers on its support site for the NVS 160M so that is what I'm using there.

In any case here is the issue. I install Win7 on the laptop and install the video drivers... native rez on the laptops is 1900x1200 (WUXGA). Aero glass is enabled and all is well and good.

I then take the laptop and connect it to the Dell-specific docking station (the D/Port in the case of the D830 and the E/Port for the E6500). In both cases there is an external monitor connected via DVI that also has a 1900x1200 native rez. The laptop lid is closed and the laptop is in suspend/sleep mode when docking.

Once in the docking station I power the laptop back on (it resumes from sleep) and then it goes about detecting the presence of the dock and the attached peripherals. The welcome screen comes up on the external monitor and I type in my password to get back to the desktop.

The only problem is that aero is now disabled (the taskbar and window borders are now opaque and aero peek no longer works, etc.). I have looked all over the net and tried ... Read more

used to use ThinkVantage's Access Connections to manage my network connection profiles on my Thinkpad. I just recently uninstalled it because I decided to just rely on the Vista has natively.

Since our office requires static IP, I set that up at the LAN properties.

Everything works fine when I start from a clean boot. It's when I undock and redock to the docking station that problem starts.

I lose the static IP configuration. Instead Vista assigns:
IP: 169.254.77.37 (supposed to be 10.11.2.xxx)
Subnet: 255.255.0.0 (supposed to be 255.255.254.0)
Gateway: blank
DNS: correct

I now find myself having to do a reboot everytime I just need to undock and go to a 30 minute meeting when I used to be able to undock and redock without any problems whatsoever.

Why does Vista assign this random IP when it is hard configured?

How can I solve this problem?

Thanks.

When I come to work I dock my laptop, lid closed, press the power button on the dock and after a few seconds I'm ready to work. When I leave for home I undock and put in my bag. It takes me an hour to reach home during which time the laptop is in my bag, not being used. When I get home it is hot since it didn't go into sleep. At home when I leave it for a while, it goes to sleep (plugged is 15 minutes or unplugged 30 minutes) 1. Why won't it go to sleep after I undock?2. Why won't it go to sleep after an idle timeout wake timers are disabled when unplugged and powercfg -requets shows an empty list. How do I fix this situation? I know I can undock, open the lid (wait for it to come on), then close again, but this is tedious and a lot of times I'm in a hurry and forget.

Hi I have had two X260's now which after undocking ( from a Lenovo Think pad pro dock ) the laptop keyboard stops working, charcaters dont appear on the screen until you tap the small red mouse in the centre of the keypad, each time you want to type you need to hit it again.  Once the laptop is redocked the keyboad works as normal again.  Is this something anyone has come across before ?

Hi, I have a User that is being disconnected every time she undocks. It remains disconnected for about 5 mins, unless she reboots and it connects straight away. The Dock is connected via a Ethernet cable, would this override the WiFi connection whren docked? If so would this then when she undocks it has to restart the adadpter and reconnect to the WiFi? If so is there a way to disable this feature?SpecsX250 Thinkpad40A0 basic dockO/S windows 7 enterprise 32 bitIntel Duel band Wireless AC 7265 adapter Thanks in advanceSU91

A user of mine is telling me she gets a BSoD often when she wakes up her laptop from sleep, or if she tries to undock it. My free tools for analyzing the dump file aren't giving me anything useful, so I figured I'd post it here in case someone with better tools would give it a shot.

Thanks!

A:BSoD when coming out of sleep or undocking

I've just had a quick look and the dump is blaming memory corruption, it would be worth doing some memory tests while you wait for the BSOD folks to take a good look at the dump.

Hi folks, I've just gotten a new laptop at work (Dell E7270 - Windows 7 Pro 64-bit) and every time I undock it I get the BSOD. I've trained myself to make sure nothing is open when undocking but have a been burned a few times, where I lost open files.

Hoping someone can lead me in the right direction to get this resolved.

Thanks in advance.

I used to use ThinkVantage's Access Connections to manage my network connection profiles on my Thinkpad. I just recently uninstalled it because I decided to just rely on the Vista has natively.

Since our office requires static IP, I set that up at the LAN properties.

Everything works fine when I start from a clean boot. It's when I undock and redock to the docking station that problem starts.

I lose the static IP configuration. Instead Vista assigns:
IP: 169.254.77.37 (supposed to be 10.11.2.xxx)
Subnet: 255.255.0.0 (supposed to be 255.255.254.0)
Gateway: blank
DNS: correct

I now find myself having to do a reboot everytime I just need to undock and go to a 30 minute meeting when I used to be able to undock and redock without any problems whatsoever.

Why does Vista assign this random IP when it is hard configured?

How can I solve this problem?

Thanks.
 

A:Vista loses IP config when undocking

I suggest re-installing the working solution, perhaps that's why it's there.

HiI have massive problems here with my setup:2 screens connected to WiGig 40A6. 1 HDMI, 1 DPX1 Yoga 1st Gen (20FQ) freezes every time when I undock. Freeze means: only possible way to get out of this is the power button. It seems, that it is not always the same:Worst case is, if both screens are connected. Then it freezes at every undock.A bit better is, if only DP is connected.A lot better is, if only HDMI screen is connected. I tried a fresh Win10 64 Bit install with all windows updates.I tried with the drivers on the X1 Yoga site at lenovoI tried with newest drivers for WiGig, from Intel, with newest driver for Intel HD graphics 520 from IntelI tried with older driver for Intel HD graphics 520 from X1 Yoga site at lenovoI did not find any working configuration. Undocking (and also rebooting, or shut down) is not possible without freeze. Does a working  configuration exist?Thank you for any suggestion!Roger

Hello all. We are seeing this issue on a handful of T440's. When the user has the laptop docked and hard wired his network drives are connected and accessable. When they undock the laptop the drives is still showing but when they try to open any home drive folders they get the error " This file is currently not available for use onthis computer". The users are connected to our network wireless before they undock so it would seem that the connection to the home folders would still be there. Any help would be great. thanks, Matt

I have a Dell XPS 15-9550 with 512Gb SSD, NVIDIA GeForce GTX 960M, and Intel 530. The SSD is encrypted using Bitlocker. I use it with an external monitor Dell U3415W. I’ve had intermittent problems with internal display blackout since day 1. I’ve had to force power down (10 seconds on power button) dozens of times. Sometimes it takes 2 or 3 cycles to come back.

As of a couple of days ago it appears the internal display has completely stopped working. There is back light but no image and no mouse. How do I recover this display?

I have encountered an issue with the volume control on my T460S that occurs when I remove my thinkpad from the docking station hot.  The volume control goes all glitchy, flickering between ON and MUTE rapidly and popping the volume monitor (pictured) up in the top left of the screen on top of everything.  Hitting <Escape> briefly dismisses it, but it comes back randomly.  When I return the laptop to the docking station (hot) the problem goes away.  I've checked the Realtek driver, and it appears to be the most recent one.  Any ideas?   Windows 10Pro, T460s

Anyone know of a solution for this? Almost every time I undock or re-dock my laptop after a meeting, something will be unresponsive, i.e. my Ethernet cable will fail to be detected or my wired keyboard becomes unresponsive. This is generally solved by a reboot (reseating the cable to the device that is failing has not generally worked), but I don't think this is necessary to solve the problem each time. I am still needing to look at things such as drivers (knowing that Windows 10 has its own method of fetching compatible drivers over HP Support Assistant or what's offered through the site). Specs: HP Zbook 15 G2Inten 6th gen I7 Processor16 GB RAMWindows 10 Professional 64-bit  Hardware attached to docking station:Wireless MouseWired KeyboardEthernet CableVGA cable to Samsung Syncmaster BX2431Power Cable
