to change 'quick start' settings (no effect).

The only way to wake up the computer is hard shut down first and then power up. I tried to set power options to hibernate on lid close but after lid close (waiting till it gets completely in hibernation mode) and then open lid nothing works at all, the computer feels like dead. (EDIT: also noticed, if I have USB device in and try to remove during screen is black, I hear USB remove sound, so something is working) I tried changing in power options that on lid close computer won't go to sleep, but after closing and opening the lid screen is black and again unresponsive, but I hear the computer working while it doesn't go to sleep mode. The only way out of it is hard shut down (by 10s holding power button). If I try to put finger on fingerprint sensor (because I already tried any kind of key combinations) I see laptop waking up (ventilator starts spinning) and keyboard backlight light up too (weird), but the screen stays black and nothing else more happens, the keyboard simply does not respond to any commands ( neither 'Fn' shortcuts work, like trying which off keyboard backlight) it feels like windows frozen and completely unresponsive. When I press any button (like space button or any other) it does not wake up the computer, by pressing the power button also show no response. Then I close lid computer goes to sleep, as it set in additional power options ' Choose what closing the lid does', later I open the lid and I see power button slowly blinking stating sleep mode.

so everything works fine till I close the lid and try come back later. I just bought Lenovo Yoga S740-15IRH i7-9750H 15' and after getting everything set up and updated I noticed one annoying problem.ĭoes someone had a problem when the laptop screen is black after closing and opening the lid?
