S440 black screen with flickering cursor after Windows 8.1 update


I have an S440 and havee had it for one week. Two days ago I downloaded the Windows 8.1 update from the store.

Since then, when I start up the computer, it doesn't even taken me to the 'sign in' screen. There's just a black screen. When I move the cursor, it briefly appears, flickers, then disappears again.

I understand this is an issue with the graphics drivers. So I ran Windows in safemode and disabled Intel R HD Graphics family and AMD Radeon HD 8600 series graphics drivers.

This, unfortunately, hasn't fixed the problem. It still boots to a black screen with an occasionally flickering cursor. I'm currently running in safemode.

Any advice?


This issue may be affecting the systems below:

  • ThinkPad S431
  • ThinkPad S440
  • ThinkPad S531
  • ThinkPad S540
  • ThinkCentre M93z


To resolve the issue

  1. Boot into Safe Mode to uninstall and delete the AMD display adapter driver from Device Manager.
  2. Then, reboot into Windows and run Windows Update to automatically install the proper AMD display adapter driver.


Detailed instructions:

  1. At the black screen, press and hold the power button until the system powers off. This typically takes 5-8 seconds.
  2. With the system still powered off, press and hold the Shift and F8 keys.
  3. While still holding Shift and F8, press and release the Power button. Continue to hold Shift and F8.
  4. The Lenovo logo should appear on the screen followed by Please Wait. Release Shift and F8 at this time.
  5. The Recovery screen should appear. If only a blank screen appears and not the Recovery screen, retry steps 1-5.
  6. From the Recovery screen, click on See advanced repair options.
  7. Click on Troubleshoot.
  8. Click on Advanced Options.
  9. Click on Startup Settings.
  10. Click on Restart.
  11. The PC will now reboot to the Startup Settings screen.
  12. Press 4 to Enable Safe Mode as prompted.
  13. The PC will now boot to Safe Mode.
  14. Enter your user name and password as prompted to log into Safe Mode.
  15. Open the Start screen.
  16. Type “devmgmt.msc” and press Enter to start Device Manager.
  17. Double-click on Display Adapters to expand the Display Adapters category.
  18. Right-click on the specific AMD Radeon HD device and choose Uninstall from the menu.
  19. At the Confirm Device Uninstal prompt, check the box Delete the driver software for this device and then click on OK.
  20. Restart the PC.
  21. The PC will now boot to Windows normally.
  22. Enter your user name and password as prompted to log into your PC.
  23. Make sure your internet connection is working and then run Windows Update. Choose to install all available updates.
  24. The PC should now be functioning normally.

Another solution i tried and it worked well.


Restart your Laptop then click F8 before the windows screen --then Repair your Computer-- System restore --then delete the last updates your system installed and choose one of the latest restore points--this will restor then restart your laptop.If you faced any problem restoring from a point just choose another restoring point.


I had this problem with 31 lenovo Yoga laptops after some system updates.Hope it works with you
