Product: HP ProBook 455 G7 Notebook PC

Hello folks,

 

I have 455 G7. All is up to date. When i turn on my laptop in the morning, sometimes I have a black screen. I see HP logo and next UEFI should be loading Windows. CPU fan working normal and there is a light on keyboard and screen of course.

Earlier it was Windows 10 and everything was fine even I changed RAM from 8GB to 16GB. Long pressing power button and pressing it again helps of course and laptop is rebooting normally.

 

It's started when I installed Windows 11 on new NVME PCI 3.0 drive (changed from PCI 4.0 because its not big deal on data charts). Any ideas? Maybe there is a mess in this new BIOS update.
