Legion 5-15ARH05 - Black Screen on Sleep and Startup

2020-09-03, 14:31 PM

I've had my Legion 5-15ARH05 (AMD Ryzen 4600H, GTX 16050-Ti) for just under a month.

 

Almost every time the screen turns off or the computer goes to sleep, the screen will not turn back on when I resume using it.  Keyboard indicator lights will be on, and I can hear the fans running, but nothing I do seems to get the screen back on, and I have to force a hard reset by holding the power button down.

 

Lately, the issue has also started occurring regularly on start-up.  That is, when starting the computer for the first time, fan, keyboard backlight and indicator lights all turn on as though it is going through a normal boot-up cycle, but the screen will not turn on.

 

I have installed the most current Windows Updates and updated the BIOS.  I've also deactivated Windows fast start-up.  Nothing seems to have addressed the issue.  

 

Any suggestions?  Thanks!

I don't have a solution, but I not long ago posted almost exactly the same story from me with a month old legion machine!    Seems too much of a coincidence to me!

Both issues seem to indicate that the graphics set is not waking up (technically resetting) after sleep mode.

 

First, try reinstalling the integrated intel graphics drivers.  There are several posts that indicate the drivers seem to get corrupted.  Don't worry about the nvidia drivers, just reinstall the intel drivers.

 

Then, try the suggestions in this article:

https://windowsreport.com/windows-10-black-screen-sleep-fix

 

I'd be specifically curious to know if the, "much lesser known shortcut" to reset the graphics driver, works while you are sitting there waiting for the black screen to change.  Windows key + Ctrl + Shift + B is supposed reset the graphics card.

Thanks very much for the suggestions!  My Legion is running on an AMD Ryzen processor; would reinstalling the integrated Radeon drivers address the same issue even though it's not an Intel chip?

Hello, I have a 10980hk/2080s and also experienced this black screen that you can't get out of but there's power going to the pc. I'm unsure what to do and was wondering if anyone reached out to lenovo?

Hi,

 

 I have a Legion 7-15IMHg05 and the same thing happens. Every time the computer's screen goes off, it won't come back and I have to manually shut it down and boot it back up. I changed the option so that the screen never turns off. Has someone been able to find a solution for this?

Happens the same with a 1 day old machine, difference is... I cannot even get into Windows, restarting does not work.

 

I let it all night shutdown, opened it up in the morning and booted up OK, then closed it for 5 minutes, when I came back it was all black and inaccessible again.

 

I guess it is warranty time, hope it does not happen again with a newer machine.

I had the same problem with my Legion 7i on intel platform.

Whenever my screen would turn off it wouldn't turn back on untill i forced a reboot, however everything started working like it sgould when i changed the graphics device in the bios to dynamic graphics.

In the bios(f2 to enter)

Go to Configuration 

Graphics Device 

Change from discrete Graphics to Dynamic Graphics

The screen should start working again.

Thank you

There was an issue with previous nvidia graphics driver I had exact issue on my legion 7i. Updating to the latest driver fixed my issue.
