Debian 9+ - Laptop suspends on boot and shutdown if lid is closed, laptop suspends if lid closed on login screen

I encountered a very irritating problem on a Acer Aspire E1-571 using Debian 9.

Starting it or shutting it down with the lid caused the system to suspend instead and wait with an orange blinking light.

I found a workaround:

Edit /etc/systemd/logind.conf

Uncomment and edit the following lines so they end in ignore:

HandleSuspendKey=ignore
HandleLidSwitch=ignore

Update for Debian 11+

A similar problem and solution for Debian 11, the laptop suspends if the lid is closed on the login screen (LightDM).

Edit /etc/systemd/logind.conf

Uncomment and edit the following lines so they end in ignore:

HandleLidSwitch=ignore
HandleLidSwitchDocked=ignore
