Legion Y740 The screen turns off and on

2019-12-25, 9:46 AM

While working from the battery the screen suddenly goes black and then turns on again. Happened several times already.

Hybrid mode is ON,

Drivers are up to date

 

Any ideas?

Hi NotDFined!

 

We'd like to know more on what is happening on your computer. Does the issue only happen when Hybrid mode is turned On?

Does it also happen when you are on the BIOS of the computer for us to isolate the case between software and hardware?

 

Regards,

Jerry_Lenovo

Ever figure this out? Mine just started doing this, but I AM NOT on battery power. The screen will turn off then come back on with a brighter screen setting...

Hi icer22x,

No, but it doesn't happen anymore either on the battery nor on the power supply. Don't know what it was :(

Glad to hear that it is no longer happening anymore on your computer. It seems that it might be related to the drivers of the Intel Graphics card. Was there an update or a change on its drivers?
