Lenovo T400 / T500 :: How To Turn Off Display If Windows 7 Is Locked
Nov 20, 2014
I just bought a Lenovo ThikpPad T540p as a replacement of my old Lenovo ThinkPad R61i.What i'm looking for, is to turn off the internal Display if Windows 7 is locked. On my old R61i, it was the Hotkey FN + F3. I was easy able to changing the function of F3 in the "Energy Manager 6" on the R61i.I did not found any similar option on the new T540p.Because i use is very often when i run the laptop during the night and i sleep in the same room. Then i usually lock Windows an turn off the display.
Windows 8.1, 64bit, all drivers up to date, Nvidia 730m, intel 4600. Fairly new issue (couple of months), laptop wakes from sleep but display does not function, everything seems to be working normally during, just no display. Forced to hard restart.
Just avoiding using sleep mode for now. Seems to be a software issue, upgraded to 8.1 when purchased almost a year ago, worked fine until recently.
My T400 display works at BIOS startup but goes black was soon as Windows 7 starts to load.. Video out put works and I can see an UN Backlit image on the display. Is there some sort back light controller /driver that may be broken.
Bought a refurb T400 and installed a PNY SSD in it. It POST's okay and I can access bios. I can also read/install Linux from DVD just fine.
Trouble is when I insert my win7 home premium DVD into the drive and boot it, I get POST and then I get a black screen. It seems to be reading the drive and when I interrupt with the Esc key or open the DVD drive, I get a Windows menu explaining that the installation has been interrupted.
I've looked at the bios options and can't see anything obvious that should be changed.
How do I turn off the UltraNav pointing device? I just use the Trackpoint and its very frustrating to keep brushing against the UltraNav and move the cursor unexpectedly. Note that my T400 doesn't have either the Thinkvantage Productivity Center or the Thinkpad Configuration programs installed.
Just got a new T420 and tried the webcam feature but unfortunately it doesn't work. When Fn+F6 is press I only see the audio settings. I installed the latest driver from LENOVO and rebooted the system but it's still the same, just the audio settings. Updated the communication & hotkey as well.
My Lenovo T500 will not turn on, despite being plugged into the wall. Even when it's plugged in, none of the indicator lights show that the computer is plugged in. It also won't turn on using the battery.
I just got my new laptop today - but I can't open it to turn it on. My old T61 has a little latch on one side you just flicked and it opened right up. This has two silver things on the front, but I've tried everything and I can't get it to open. I've pressed one, both at the same time, pressed hard, pressed lightly. Been trying to open for over 20 minutes now but it won't budge.
Will I have to send it back solely because I can't open it?
Is there a way to turn on or off the wireless/bluetooth radio when the T420 is docked and using an external keyboard? I don't want to open the lid on the T420 every time to use the Fn+F5 keys when docked.
I have a t420s and so far I'm happy with it.Recently I purchased a MC7700 card from ebay with lenovo FRU. Everything looks smooth except that I found there is no way to turn on the mobile broadband switch.i believe I have a whitelist-removed bios otherwise it won't boot. The driver downloaded from lenovo website is installed fine, I can see the card working in device manager. I could read the iccid in windows network settings. Everything looks good, but I just can't turn mobile broadband on.
My laptop runs windows 8.1, I heard there is a thinkvantage connectivity tool that might work for windows 7 but not windows 8. I have quite a few files on my laptop and going back to windows 7 is the last option I would like to try.
I have tried to make a fresh Windows 7 installation, but after installing updates via Lenovo System Update the system gets corrupt.I replaced the hard drive on an T400 and loaded a image that I had on to the drive. After a installing a few updates and program I noticed strange system beaver. So I did a system file check and it came back that files was corrupt and cold not be repaired.So I did a new fresh Windows install. But it to became corrupt after just running Windows Update and Lenovo System Update.So I ran some hard drive and memory diagnostic without find and problems.
Then I did a new Windows 7 install again. After I installed all recommended updates from Windows Update I did a system file check, all OK. The I installed Lenovo System Update and all its recommended updates and did a new system file check, Windows system files corrupt. What Lenovo update is destroying the system?
When I connect second display via regular VGA cable I can set the maximum resolution to 1920x1080, although native resolution for my external screen is 1920x1200.
I could just find posts related to similar problems when using docking station - tried some of the solutions, but none seemed to work.
Found this [URL] ... on dpreview - suggests using miniDP to DP 2-link converter (screen has just VGA/DP ports).
I got T510. The display went out and all I can see is flickering screen so I cannot see anything. I am getting T540p. What is the best way for me to move data from my hard drive to the new one? At least I would like to move pictures and documents, I got no backup.
I was watching a film on my projector, from my Lenovo T510 laptop, using a Display Port to HDMI cable. There was a thunderstorm and a powercut during the film, but my laptop wasnt plugged in at the time. Then when I touched the Display port end of the cable, which is plugged in to my laptop, it was too hot to touch, and had was slightly bulging and mis shapen! Now it has cooled down and just looks and feels normal. Very strange, and I dont see how it could have been related to the storm and powercut, but it seems a bit too coincidental! I have used this cable multiple times before and never noticed this, but then again maybe I wouldnt have ever touched it until it had cooled down. But I it was pretty much metling it was so hot, so I would think Id notice it.
Using the projector setting, I'm noticing a slight lag when I open/close any of the applications (ie: there is a momentary pause before the window either appears/disappears).
The external monitor is a Samsung Central Station (1920x1080) and connects to the laptop wirelessly via a USB/UWB dongle.
I have a brand new TV with USB, RS232, HDMI connections and of course with a screen in16:9 aspect ratio. I want to use my existing RS232 cable to connect my T430 to the TV and display videos/movies that I want to view with others. HOWEVER, the video output always gets a black bar top and bottom from the T430 when the TV is connected. As a result, the image is stretched side-to-side both on the TV and on the T430 simultaneously showing the video. It is ugly. If I watch a movie in the very wide movie format 2.35:1, the bars are of course even larger and the movie is simply unwatchable it's so thin, top-to-bottom.
This is true regardless of the video source on the T430, either a movie via VLC or MediaPlayer off the hard drive, or streaming.
Two odd things: it does not happen if I play a movie on the TV directly from a USB key - it has a USB port and that works just fine. Also, if I simply unplug the RS232 from the TV then everything gets restored and the image on the T430 is perfect without any bars top and bottom.
In summary, a 16:9 video source connected to a 16:9 TV via RS232 is given black bars top and bottom, and there is no control on the TV that can correct this (TV has two settings for RS232 display, 4:3 and 16:9. 4:3 actually displays the 16:9 ratio correctly, but with a large black frame around it. And 16:9, the "auto" setting, gives the problem above).
So I have two questions:
1. Is there a setting on the T430 that I can adjust to resolve this issue so that the black bars are suppressed for 16:9 video replay?
2. If I switch to using the more expensive T430 minidisplay output (via an HDMI adapter) and connect that way, is it likely to fix this issue? I don't want to go to the expense of the adapter and HDMI cable if it will give essentially the same result.
This only applies to videos. That is, when I close down the video, the 16:9 desktop that shows on the TV is identical to that on the T430 and aspect ratio is not squished on either display.
So it's something to do with how the machine sends out the video streams via RS232 that's screwed up somehow.
I wanted to go today and get an adapter for my Lenovo Thinkpad T430 and first I thought I should do some research. This is how I found out that most of the Thinkpads do not send audio over DP, as I would have expected.
I have the T430 (no discrete graphics, just the integrated one) and Mini Dock Series 3 with USB 3.0 (EU1) docking station. The laptop has mini-DP and the docking has a normal DP. The normal DP works fine with my monitor, but it doesn't have any speakers in it , so can't test the audio part.
I checked in Audio properties in Windows (7 x64) and I don't see the video card there, so I am assuming it is not supported. I don't want to buy adapters if the laptop is unable to send audio over a DP-> HDMI adapter.
I have a 3-yr old Thinkpad T500 laptop w/ XP. My on-screen volume and brightness displays have recently disappeared. Spoke with customer support and was advised to download all the machine updates....did that, but still not working.
I bought this computer which is running 7win64 to update my T60 which I use with my home TV, a samsung digital running at 1360x768 resolution. The computer's native resolution is 1920x1080. I bought an hdmi adapter for the displayport from lenovo when I ordered the computer. Initially, the display works and at first it ran long enough to get everything set for a nice crisp display that fits the screen perfectly. The sound is there too, and is passed on to my receiver by the TV. Very nice. But then it begins to blink off until it doesn't work at all (the sound is cut off too). Lately it won't stay on long enough to review settings.
All updates are in place, both from microsoft and from lenovo. This has Intel 4600 graphics built in, and intel has graphics drivers available, but won't install them because of the lenovo supplied drivers.
I can't get any support from lenovo support because another device is involved.
I read online of some early users who had this problem with a docking station and i guess the problem was resolved with an updated driver.
I tried to do fn + f7 to toggle display modes as I want only laptop or monitor display, not both. But when I do fn + f7, the small window pop up ask me if I want to turn on caret browsing or not. How to toggle display modes between laptop or monitor for t440p, window 8.1?
My T530 (a month old) is driving me crazy with this issue: Depending on which application is in the foreground, it will dim/undim the built-in screen (1600x900 version). I have turned off adaptive screen brightness in the power options, and I've turned off Film Mode Detection and Adaptive Contrast Enhancement in the Intel Graphics and Media Control Panel, but this "feature" won't go away.
How in the world can I get the screen to be on 100% brightness, unless I manually change it?
I have a T420 Thinkpad and have 2 external monitors connected; one using VGA into the docking station and one using DVI into the docking station. The laptop does not recognize the mobile PC display as an option when I attempt to extend to a 3rd monitor. The ultimate goal is 3 monitors extended: 2 external and 1 (the laptop display). Is this possible?
Lenovo T400 to install Windows XP on it..It previously worked fine with windows 7 and 8.1.so it boots in windows XP preinstall screen, it formats hdd and like usual installation automatically restarts after that BUT its black screen, lights and sounds show that it works and goes to next screen BUT the screen is still black. Powering down and turn on again is not showing any screen picture. Opened it removed Bios battery, turned up after few on and off it starts it reset bios.
So now there is picture and it goes on the next screen of windows instalation like normal, after installing devices and stuff it automatically restarts like usual BUT it has NO screen again, black screen, lights and sounds again show that its loading windows end instalation screen but no picture on the screen. Reset BIOS again, it starts normaly and this time it shows BSoD with code 0x7B, after BSOD Black screen again..Maybe its a BIOS setting?!? tried installing with drivers for AHCI and tried installing without drivers for Compatible , what else can it be? Updated the bios to latest version, same result. To say it again - it works fine with other windows, but XP must be installed
I am using T440. I just upgrade the operating system from windows 7 to windows 8 using recovery disk. I upgrade according to the manual paper in the box.
The issue is, the windows 8 is installed in my HDD with capacity 500GB and the SSD 16GB are not detected. My question is, it should be installed in my 500GB HDD or the SSD drive? What are the correct steps to do recovery if I 500GB HDD and SSD drive?
I cannot install Windows 8.1. I have a T430. I go into the app store, start installing 8.1, it downloads, starts installing, and fails just after that point -- at 54% -- with the error message 0x80070002. That apparently means "File not found", but the Windows Update logs don't point to which file is not found, only giving:
