It sounds like it is not resuming from Sleep mode, which is a known issue with the latest Windows 10 1903 update, and was probably installed as part of those Windows updates, so try this step to get it back up and running.
On the bottom of your laptop there is a very small Emergency Reset hole next to the center screw (see image below).

With the AC adapter unplugged, use a bent paperclip etc. to gently press and hold the button for about 5 seconds, then re-attach the AC adapter, power up the laptop, and with any luck it will boot normally.
Your system probably has both the Intel UHD Graphics 630 in processor, and the discrete NVIDIA GeForce GTX 1050 Ti, so you need to get the latest drivers for both of them installed.
Intel's driver installer checks to see if you are running an OEM (e.g. a Lenovo) driver, and if so will give you a compatibility error and direct you to Lenovo, so to install the latest DCH driver from Intel, you must first switch to the Microsoft Basic Display Adapter driver as detailed below.

Before starting, download the latest Intel DCH driver for your graphics adapter and disconnect any external monitors etc. for the time being.
Right-click on Start and select Device Manager
Click on "Display Adapters" to expand, and then double-click on your Intel HD Graphics adapter
Select the Driver tab -> "Update Driver" -> "Browse my computer for driver software" -> "Let me pick from a list of available drivers on my computer"
Select “Microsoft Basic Display Adapter”
Click “Next” (note that your screen resolution will likely change when it switches to the Microsoft Basic Display Adapter driver).
Close Device Manager
- Reboot if prompted
You should now be able to install the latest Intel DCH driver installer successfully.

I usually uncheck the option to install their GeForce Experience application during the installation since it is mostly tailored to gamers, but you can read more about it here and make your own choice.
Best of luck,
