Y50 Black Screen and no ability to enter safe mode

My Y50 recently went to black screen and does so upon starting and showing the 'Lenovo' name. So before the login screen.

 

  • I am able to access the Troubleshooting and have tried earlier restore points with no success. It tells me it has successfully restored an earlier point and returns to the black screen. 
  • I have checked it is not pointing to the wrong output by using Windows button and P. 
  • I have tried entering the various safe modes, through the troubleshootiong route and again, it just moves on to the black screen and not into safe mode. 
  • looking at the restore points available, it seems an update to Windows 10 may have occured on around the time the trouble began.

Any other suggestions that i should try?

Re: Y50 Black Screen and no ability to enter safe mode

Hi james227,

 

Welcome to the Community Forums.

 

You can still try to force shutdown 2-3 times for the advance boot option to enter safe mode as indicated here

 

Otherwise you may take the option to back up your files first by manually removing your drive and placing it on another machine or external enclosure if needed. 

 

Then you can safely proceed with repair install or custom install if reset and other advance option stilll fails.

 

Update us how it goes best for you.

 

Regards

Re: Y50 Black Screen and no ability to enter safe mode

Thanks. I have entered the troubleshooting via the forced shutdown method but still unable to enter safe mode. 

 

I did run a 'reset pc' and it went through the process but then during the windows install this error message came up:

 

"Windows setup could not configure Windows to run on this computer's hardware"

 

does this help you at all?

Further update; when the reset failed the system went through a 'undoing changes' process. After that and for the first time in days it reached the login page. However, it will not accept my Windows's password and when I choose "I forgot my password' it shows the error " Windows couldn't connect to the ProfSvc service"

Hi james227,

 

Greetings.

 

Back up your files as I suspect corrupted system files that may lead to repair /upgrade install if not resetting to factory image via novo key as last option.

 

Regards
