Hi Louis, You should not try to disable ACPI these days. It was a recommendation in some cases probably ~15 years ago, but for many years now modern systems depend on ACPI for proper operation. I have no idea what causes crash in your case, but I would not expect it to end up good any way. I know nothing about GNOME, haven't touched it for many years, but it must be it what makes your laptop to sleep. FreeBSD itself does not implement such automatic policies.
