Screen blank requiring hard restart

[Sandy19821]

Hi I have HP Pavilion - 15-cc123cl. For the last few months , if I leave the computer unattended for more than 10- 15 minutes, the screen go blank/black, harddrive light is not blinking, no mouse cursor on the screen. This only happens when I am not using the computer. And once it happends the only way is to hard restart or let the battery go completely off.  It can work for extended periods if I am actively using the laptop. The work around I am using is putting it to sleep or hibernate or turn off before next use. I updates the BIOS as per HP. Please help with what next steps I could take

Thank you

Win10 has enabled a new hibernation process known as Fast Startup -- which is enabled BY DEFAULT. This is different from Fast Boot, which is a BIOS/UEFI option.

Fast Startup is supposed to dramatically speed up the booting process, but in some PCs, it actually slows it down or causes it to hang. It's also a new form of hibernation known as hybrid sleep -- and this causes battery drain to maintain the state of the PC while turned off.

Disabling Fast Startup might fix booting and shutdown problems.

There are two ways to disable FastStartup in Win10: (1) through the Control Panel, and (2) through an elevated command prompt.

Control Panel - Open Control Panel --> Power Options.
Select "Choose what the power buttons do"
Select "Change settings that are currently unavailable"
At the bottom of the Window, under Shutdown settings, uncheck the box regarding fast startup

Elevated command prompt - run the following command:
REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power" /V HiberbootEnabled /T REG_dWORD /D 0 /F

In both cases, reboot Windows.

NOW, FastStartup is disabled.

See if that helps.

Have the same issue with my Envy 360, and it's not the fast start up because mine was already disabled. I also updated the BIOS, graphics software and then I reinstalled windows (even deleted all of my files and started from scratch), and I still have this issue.
