The battery monitor icon should show up if you select "Show Battery
Monitor" in the "Battery" tab of the "Control Center > Power Control >
Laptop Battery" menu. The "Start Battery Monitor" button on the bottom
of that tab should work as well.
It will not show up, however, if you (accidentally) disabled the system
tray of the panel. You can activate the system tray by right-clicking on
the panel and selecting "Add Applet to Panel... > System Tray". If the
system tray is already active it might be worth a try to remove it
("Remove From Panel > Applet > System Tray") and add it again. Still no
luck? Check your ~/.xsession-errors log for error messages which might
be related to the battery monitor.

If you press the key combination while acpi_listen is running you should
see something like this:
hotkey ATKD 00000030 00000002
The "00000030" would be the keycode which you need; the other number is
a counter which is incremented every time the key combination is
pressed. I can post an example script here to help you set up the volume
control, but it will not be of any use to you if your system does not
recognize the ACPI event. Like I said before, many laptops offer only
partial ACPI support under Linux, thanks to the Windows-centric
manufacturers and their broken ACPI implementations. Upgrading to the
newest version of the BIOS can sometimes improve the situation. (Please
keep in kind that I have no specific knowledge of your particular laptop
model.)
