Mi book air ubuntu 1804 - the laptop does not wake up after blocking, how to overcome it?

Question

laptops

Hello.
I bought a xiaomi mi book air 2018 laptop, it has windows 10 home preinstalled, just in case I decided to leave it.
Ubuntu 1804 installed side by side.
The essence of the problem is below:
I block the system, the screensaver turns on, after half a second the screen goes blank. I try to wake the system from the keyboard - nothing happens, every other time. Tried to include terminal desktops - not an option. Saves only reset. It is critical for me to be able to lock my laptop and quickly unlock it. Ideally, he would not turn off the screen at all, but show the splash screen in a locked state. Help, please, to overcome a problem. What can be wrong? bios is extremely truncated, there is nothing like it, except for "waking up from the keyboard", which is set to ON.

Install Windows 10 ltsc and ubuntu via wsl.
