Display blank after opening lid

2020-07-28, 12:27 PM

I have Ideapad 720S-141KB.

This problem started yesterday after I updated the LENOVO BIOS and to the new Windows 10 2004 version.

If I close the lid, the laptop goes to sleep but after opening back the lid the pc seems to start (fan noise) but display is blank.  Pressing the power button does not help.

If I go to sleep mode by pressing power (not closing the lid), then when after pressing again the display works.

I set power saving settings to default but it did not help.

Same problem happens when the laptop is plugged-in or on battery.

Thx.

Did you find a fix already? I do have the same problem after firmware update.

You need to back flash to BIOS firmware. This fixes the problem!
