Hi

Could you please expand on the

MAKE, MODEL, OS and SKU?

1st Please try a Hard Reset
This is valid for most notebooks, and some desktops.
Press and Hold the PWR off button for 4 seconds to force a PWR off.
Unplug from the wall.
IF you see a battery compartment door, then your computer has a removable battery.

IF NOT then you do not have a removable battery.

Remove any removable battery.
Press and hold the power button for 15 seconds to complete the reset.

(Re-insert any battery you removed).

Turn off the notebook.
Plug the notebook into a power source using the power adapter.
With the notebook off, press and hold the Windows logo key and the B key at the same time (WinKey +B).

NB: On some notebook models, it might be necessary to press and hold the Windows logo key and the V key (WinKey +V).

While pressing those keys, press and hold the Power button on the computer for 2 to 3 seconds, and then release the Power button but continue to hold the Windows logo key and the B or V key until the HP BIOS update screen displays or you hear a beeping sound (usually 8 beeps).

ESC and then F2 for a Diagnostic if you can.

and if you need a W10 OS for re-installation...

ISO images of various Microsoft OS's are available.

They can be be downloaded (sometimes you need a licence key other than the HP OEM key)
and 'burnt'/expanded to a DVD/USB. They WONT contain appropriate HP software, like drivers etc.
But may enable a repair to be started.
