As branded laptops can have a different set of keys to do certain things, but...
Windows 10 doesn't have the old 'Safe Mode' that previous Windows did. However, you can try to enable a set of troubleshooting options at boot.
Try booting the computer, and as soon as it starts to load, tap the F8 key a few times. Hopefully this will bring you to a blue options screen - I can't remember exactly what it says but you can:
-Boot normally
-Browse advanced options
In the advanced options you will find settings to roll back updates, try a system restore and a few other things. If F8 doesn't work and you have web access, this link will explain how to enable F8. https://www.drivereasy.com/knowledge/how-to-enter-safe-mode-in-windows-10/
Between you and I, I wonder if a recent update hosed your laptop - just yesterday I had a bad crash on my desktop machine and cannot diagnose the fault. I put it down to age and possible overheating of the CPU but this is starting to look a bit suss!
Good luck.
