Comment 2 for bug 199682

Thank you, Greg. I think the link https://wiki.ubuntu.com/LaptopTestingTeam/HotkeyResearch should be listed on LaptopTesting wiki page found at https://wiki.ubuntu.com/LaptopTesting page. That was my starting point for laptop testing, as directed by www.ubuntu.com web site. The guide was of great help, and now I have the complete log of events generated by special keys. Hope this helps.

There are also Wireless and Bluetooth LEDs that should be properly controlled. With asus-acpi kernel module, they all worked as they should. After switching to asus-laptop kernel module, ScrollLock LED only works in console but not in X, wireless and bluetooth LEDs are always on. This model does not have any bluetooth adapter, as nVidia chipset allows either wireless or bluetooth to be instaled. The details about the system are below:

$ sudo dmidecode -s system-manufacturer
ASUSTeK Computer Inc.
$ sudo dmidecode -s system-product-name
F5N
$ sudo dmidecode -s system-version
1.0

and the requested lspci -vvnn command output is attached.
