I had heat problems with Dell X200 after upgrading to pre-5.1 kernel.  It
hapened with both APM and ACPI. I suspect that booting with the ACPI left 
the system in a funky state, so turning off ACPI didn't help
Downgrading to 5.0 release and booting once into win/xp seems to have
fixed it, but I haven't tested it extensively..
