It seems this feature is provided by

acpi-support:

"scripts for handling many ACPI events

This package contains scripts to react to various ACPI events. It only
includes scripts for events that can be supported with some level of
safety cross platform.

It is able to:
 * Detect loss and gain of AC power, lid closure, and the press of a
   number of specific buttons (on Asus, IBM, Lenovo, Panasonic, Sony
   and Toshiba laptops).
 * On some laptops, set screen brightness."

Perhaps you could check in Synaptic - acpi-support -
Properties/Installed Files if your notebook brand is listed.
