Black screen after sleep mode and open lid

2020-08-16, 16:30 PM

Hi everybody

 

I have a problem when I close the lid of my ideapad 720s

 

After sleep mode closing the lid,  I open it, the screen remains off, even though the computer is activated, since I hear the sounds of the notifications. If I close the cover again and open it, the display is activated. All this started after updating to the latest 4VCN52WW(V2.18) bios drivers (ideapad 720s 14IKB)

 

I'd appreciate it if someone could help me, because it is very annoying to open the lid twice to reactivate the display

 

Thanks 

 

Andre.

The same happened to me after the BIOS update and can only reset by holding the power button. I had a similar problem when I bought the laptop and it was solved by replacing the SSD.

 

What happens when you return from sleep but without closing the lid? It also freezes for me, too.

 

I ran Lenovo Vantage Hardware Scan and it detected an error on the SSD.  The system stores the active session in the disk when putting it to sleep, so it makes sense that they are related. I have a SSD INTEL SSDPEKKW256G7 - 238.47 GBs

 

I also tried this:

and had a lot of trouble when rebooting. The scan could not complete and then the laptop couldn't find any bootable session. Then it boot, but couldn't login. I finally could reboot without problems after pressing the Recovery Button on the side.

Any solution to this black screen issue. I have the exact same problem for a one year old E480. All updates have been done.

I have the same issue and it started JUST after the BIOS update. I contacted lenovo support and they told me that I can take it to their support center.

 

It is pretty obvious that the issue is the BIOS update, which is outrageous considering it is such a grotesc issue which really makes everything a pain.

 

Hope Lenovo releases an update soon.

The same issue with Lenovo Yoga Slim 7 14ARE05.

And it's BIOS issue, I agree.

I've installed linux (Fedora 32) on the laptop and faced with the same problem.

I don't have this problem on my huawei matebook d14 on the same OS.

I do also experience this problem as I updated the BIOS to version 4VCN52WW, The only possible way to reset is by a forced reset (power button). Extremly annoying as documents and information might be lossed each time the computer go into sleeping mode. 

 

Lenovo staff need to fix this asap! 

 

Thanks!

Hello,

 

I am still having this issue with my Lenovo 720s (80XC) running Bios version 4VCN52WW. Is there any way to submit a support request to have this bios fixed?
