Black screen on a lenovo Thinkpad T420

• I started having problems with the wireless mouse and the carpet of my laptop - Lenovo ThinkPad T420 mouse.

  Original title: right click on the mouse itself activating

  I borrowed a USB to a person at work and I started having problems with the wireless mouse and the carpet of my laptop - Lenovo ThinkPad T420 mouse. The left click of two devices works normally, however, sometimes she does not respond to clicks and it takes a few seconds to work. The left button was constantly starts to turn on, as if he was stuck. After that I hit Alt + Tab and modify windows it stops for a few moments and starts at a later date. I havo not found a specific condition or a combination of keys that may trigger the fault.

  I read a few posts on discussion forums, but all say that it could be a hardware problem, which I think is not, because both devices have the same problem and I'm sure it all started with the insertion of the borrowed memory stick. I scanned the readers to help Symantec's EndPoint Protection and installed Microsoft Security Essentials and performed a full scan, but found nothing. I even restored the system, but the problem remains.

  Should I get a different antivirus? How can I find the cause so I can find a better targeted solution?

  Try to install the drivers from this link and check.

• Black screen on computer Lenovo Yoga Pro 2 after the opening session in Windows 8 screen

  I return this laptop Lenovo Yoga Pro 2 about a month and it has Windows 8. I start the laptop and once I enter username and password, I have a black screen with the mouse pointer. Lenovo support has been useless. They asked me to run c:\windows\system\restore\rstrui.exe by using the Task Manager, but I get the file not found. When I go to the command prompt by using the Task Manager and check dir listing in the directory of restoration, it shows empty.

  Very frustrated. Can someone please help here on the Microsoft Forum?

  Thank you in advance.

  It seems to me a solution, it worked for me, so hopefully it will work for you as long as you experience the same problem.

  Because you can always go to the sign in screen, do the following:

  Click on the power icon in the lower right to open the menu,

  Hold down the SHIFT key while clicking the button of /restart/ once.

  A screen will appear after a few moments.

  Click and follow the instructions /Refresh/ and let him go during its cycle...

  all fixed!

• Lenovo X 201 laptop computer black screen and LCD does not detect after windows startup

  Suddenly, my Lenovo Thinkpad x 201 shows only a black screen. I checked the LCD screen with a light and I could see a dark image of the Thinkpad logo and then it go completely black. But when he is on safe mode, I saw my desk in black screen (when I use a light).

  I've updated the BIOS also using an external monitor. But still the same. I'm completely at a loss. Please someone help me to slove this problem...

  It is due to the inverter of the screen which has stopped working, it controls the backlight of the LCD/LED screen part when it breaks it causes the backlight to turn off and wont go on then you would need to have ups re-place with a new one.

  Here's an example of how it looks like:

  

  It may seem different on each model, but that's just one example of a lenovo T41.

• ThinkPad Yoga - black screen

  After reading question formidable black screen for other models, I check if the Thinkpad Yoga also has the black screen problem. Since this happened just within one month after the expiration of the warranty, if it proves to be the hardware problem this has strong changes as the latest product lenovo belonging to the family.

  Question: I'm back a work House to wake up my sleeping Lenovo. Noticed that he seemed to be in mode black screen with nothing appear. So tried to press a few buttons and then finally turned off using the button. To restart, I could see the sign of Lenovo and the option to press ENTER to check the other options and I ignored as usual scenario happy path and let it go. At the time, that it usually starts showing the Windows screens, I don't see anything happen. A black screen with all the lights on the keyboard still works but no screen. Connected to the projector to see if the login screen displays, but it didn't. Tried to reboot several times, reset using the hole of pin down, ran Diagnostics and tried to update the system etc using the options of troubleshooting, checked BIOS settings - that appear on the screen and the LCD like a charm test pass, but when Windows starts does not work.

  ThinkPad Yoga 15 running on Windows 10 pro. 20DQ type of machine.

  The frustarting thing is guaranteed just expired in late July, phone support will not even discuss the issue since he arrived at expiration. I spent the right amount of days thinking about spending a lot on this laptop last year only to reach a point in a year I might have to spend little more just to save her. Help, please!

  Hello. Is it possible that system has gone through an automatic update to Windows 10 anniversary? If Yes, I have experienced the same problem - it will not start and show only black screen. For me, the previous generation ASR failed also. Here are my options:

  (1) I managed to complete the update after you follow this procedure - https://support.lenovo.com/cz/en/solutions/ht501760

  (2) if that is not enough at this point (I don't know if this setting is needed before a failed installation), I was able to recover a previous version:

  -on another computer, download Microsoft media creation tool and create and install USB offline media

  -boot from media by pressing F12 at startup and on the second screen (I think) at installation, you can decide not to install the system, but recover the system - there is a link on the lower left corner. This brings you to the recovery screen where you can revert to a previous version

  I would like to know if it's completely irrelevant, or it is useful.

• Lenovo black screen randomly Y50-70 times

  Hi everyone I have a very strange problem with my laptop. Here's the Specs (copy-pasted from amazon because I'm lazy):

  Lenovo Y50-70 39.6 cm (15.6 Zoll UHD IPS)
  Intel Core i7-4710HQ, 3.5 GHz
  12 GB OF RAM
  Hybrid SSHD 1 TB (8GB) NVIDIA GeForce GTX 860 M / 4GB

  Since I bought it (about 1 1/2 months of passes) after I installed Windows 8.1 and improved to 10 I sometimes get a black screen, no cursor as has happened repeatedly after upgrading to w10, always helped restart and everything was brilliant.

  The thing is that my screen will not turn off, it's all black, but always on (visible by the light light is always built). It started to happen very rare, perhaps after a week or so, but today I get the problem constantly with different models:

  through normal startup:

  -Start-up of the PC-> black screen

  -Start-up of the PC-> "LENOVO" appears-> black screen

  -Start-up of the PC-> "LENOVO" appears-> Windows load-> black screen

  -Start-up of the PC-> "LENOVO" appears-> Windows load-> welcome-> black screen screen

  -Start-up of the PC-> "LENOVO" appears-> Windows load-> the Welcome screen->-> connection-> black screen

  -Start-up of the PC-> "LENOVO" appears-> Windows load-> the Welcome screen->-> connection-> after a random time: you guessed it - black screen

  The list is repeated several times today which made me crazy enough then and now, also restart does not power more...

  The same phenomenon occurs during Advanced Start (the small button to the left of the power button), even when I asked for a Startup Recovery. It works well is that during safe mode.

  I tried several things, such as the removal of the Intel graphic card, which gave me access to the normal mode of the system. Here I have updated the BIOS to 3.0.3. Now, I'm testing the Nvidia Driver (relocation etc.). Interestingly, I have observed a disturbing "PnP-screen (standard)" which had a yellow flag next to it in Device Manager, although no second monitor is plugged into the machine. Maybe it's the a boring me severa hours today.

  Also, I am plugged to my TV right now which helps me get at least a photo. During this State, there are also 2 'pnp front (standard)' listed in the Device Manager, none of them with the flag...

  Guys do you know something about this problem, anyone has stumbled across it too much and THE TIPP to save me and my sanity?

  Kay, gentlemen.

  After calling amazon (seller) and Lenovo and "help" from a friend, I decided to return to win8.1. I reinstalled the drivers, settled everything back the way I needed her, saved our day by finding our Starbound universe still exists and! No black screens no more. It seems that this unit has still some problems with the operating system most recent Microsofts then Yes, I'll wait... even though I liked 10... :/

  Cases can be considered resolved and thanks for everything the world where with me on this quest. Cheers on you guys!

  I have a new Lenovo Z50-75 with FreeDOS: I made a Windows 8.1 installation, and everything went well.

  After installing the approximately 70 updates - at one point it restarts and I get a black screen, just after few see the Lenovo Logo (enter the BIOS works).

  It is not all Windows start - I can't get fashion so safe, and I don't get any cursor.

  The behavior is reproducible, 2 times. Also when it crashes at the black screen, the van get reall busy, Levy and the laptop gets hot.

  Anyone working on this issue, or has any idea what should I do?

  Thank you

  Updating the BIOS is not always my first option (risk, performance vs).

  Anyway... It works, everything is good.

• Plug the VGA cable causes the crash or black screen on my Thinkpad. Help!

  On my newly purchased W530, a cable VGA-causes a crash or a black screen on my Thinkpad.

  The foregoing happens whenever I have insert the cable VGA which is quite annoying, because I use it with my projector every day.

  Accidents seem to occur more often when I closed the lid and insert the VGA cable. If I open cover more often get a black screen (which remains black even when I leave the cable again).

  I could try to fix this problem?

  Which driver (or other) would be the most likely cause?

  Thanks Adam! :-)

  Yes, as I mentioned, accidents have disappeared after installing the latest driver Nvidias own site.

  Remaining problems are small problems which I can live with to what NVidia fixes if all goes well with an updated driver.

  But it was really great to see instructions on how to start in safe mode on Windows 8. I always wondered who. Thanks again Adam! :-)
