Okay, this seems to be consistent with the manual I linked to in my previous message. > Pressing the E button brings up some kind of Energy saving applet and > pressing the I button brings up an applet telling me about the hardware > in my laptop and its current state. These hotkeys should already work fine under Linux, i.e. pressing them should generate input events which you can assign to any action you please. If they do not work for you, please let me know so that we can debug further. > Please tell me if I can provide more Information. If I did not miss anything in your reports, there are two issues that require some work: - Fixing radio LED detection. I have an idea how to do this, but please mind that I am quite busy lately and cannot guarantee any specific time frame for submitting a patch. - Investigating the E LED. This requires taking a look at the DSDT dump from your laptop and searching for clues as to how this LED is handled. I will be happy to do that, but again, no promises about how much time it will take. (And given the nature of this task, I cannot promise I will find anything reasonable at all. I also might ask you to do some further experiments as I do not have an E751 myself.) -- Best regards, Michał Kępień
