G751JT How to prevent shutdown when screen is closed.

[Shadowthorn]

I am trying to repurpose my old G751JT as a home server.
But I can't find how to stop it going to sleep/shutdown when the screen is closed.

It is running Proxmox so all the windows based answers I keep finding are irrelevant.

Is it possible to do in BIOS?

Never mind. It is done in Proxmox config.

You can’t disable lid sleep directly in BIOS on most ASUS laptops. Since you’re using Proxmox (Linux-based), you’ll need to edit system settings — for example, add HandleLidSwitch=ignore in /etc/systemd/logind.conf, then run systemctl restart systemd-logind. That’ll keep it running with the lid closed.
