As the title says, I've got a Predator Helios 300 PH315-53: it turns electrically on, the kb lightens up and stays on, the fan spin for a moment and then they stop but the PC stays on.

Apart from this, no other vital signs: no signal on screen, no beeps, nothing.
The Power and battery LED turn on blue. If I keep it on without the PSU, the battery starts discharging and it correctly charges when the PSU is reconnected (LED becomes orange, then blue again once charged).

I've alredy tried unplugged anything I could: RAM, SDD, HDD, Battery, CMOS battery:
no changes, it stays on, kb on, with no other vital signs.

Plugging an external screen either via HDMI or via DP, doesn't change anything.
Any idea? I've been considering replacing the CMOS battery…
