start system

HP Recommended
HP ZBook 15 G3
Microsoft Windows 10 (64-bit)

Hi Good day.
I have a 15g3 hp zbook.
When I shut down Windows (it completely shuts down) and try to turn it on again, something special happens to it:
All the keyboard lights and keys flash at once, and the screen light turns a little white, and the fans start working for a moment. This happens several times and finally the system comes up. When it is on, it has no performance problems and works normally.
The interesting thing is that this only happens when, for example, I turn it on again until an hour after the Windows Shotdone, and if the time interval between half and an hour passes from the Shotdone, it will turn on normally and there will be no problem. does not have. If you need more information, let me know. Otherwise, thank you for your help. Where is the problem and how can I fix it?

the first thing i would do is run HP Image Assistant and do BIOS (most important) and driver updates, and see if the problem goes away... i would also go into the BIOS (F10 at power on) and set it to Default settings

I work for HP. However, all opinions and comments are my own.
