G50-70 graphics problems since windows 10 update

2018-01-12, 21:07 PM


I have G50-70  (80DY59421797) which has has problems since a recent windows update. It boots up to the login screen, then shortly after signing in and displaying the desktop, it goes to a black screen with cursor. Also fails to show display on external monitor. At one point it would work ok on one user account but not the other.

A couple of days ago I booted into safe mode, rolled back to windows restore point of 2nd Jan 2018, and it worked fine - until today when windows update re-installed. Again, gets as far as initial screen after login, then goes black.

Can't submit a detailed eventlog online as mailing this from another computer, but wondered if a problem with graphics driver being incompatable with very latest windows update.

currently at Windows 10 home, version 1709 Build 16299.192  . The version after I did the system restore (when it did work) was build 16299.125

Current graphics driver is Intel Corp Driver 28/3/2017 version

Tried to install the Lenovo driver at https://pcsupport.lenovo.com/gb/en/products/LAPTOPS-AND-NETBOOKS/LENOVO-G-SERIES-LAPTOPS/G50-70-NOTEBOOK-LENOVO/80DY/59421797/YB06190232/downloads/DS103877 but computer wouldn't let me as that driver is older than the one installed.


Help..... What other diagnostics should I rund, and how can I fix the problem


Thanks for any suggestions

It sounds like the update resets the resolution for the display driver to a setting the LCD cannot work with.

Boot into Safe Mode, then check driver, apply any update and set screen refresh rate and resolution to standard.

When it reboots, it should pick up on that change and clear out the problem. If not, boot back into safe mode, roll back then get the info on the update that is causing the issues and post it to Microsoft TechNet to see if they can get something going on it.

Good luck.

I have a similar problem, So after each boot I go to the Device Manager and update to one of the display drivers

on my computer manually. The computer runs normally until next boot.
