I have a (seemingly rather exotic) Dell Latitude XT2 notebook running Lubuntu 12.04, fresh install.
Tried to get the power button to work as expected (opening lubuntu-logout, just as I think it was meant to be out-of-the box), but no success: power button does nothing but forced power-off on long press.
Here some more information, please ask if something more could help:
Ubuntu is working very well on this laptop with the exception of the suspend function. The laptop will suspend and come out of suspend without a problem if it does not sleep too long. When I leave the laptop in suspend overnight however, the laptop light will blink like it was in suspend but will not wakeup pressing keys or by pressing the power button lightly.
My power button is broken but I'm not sure it's the power button because I somewhat opened it there is a stripped screw so the volume side doesn't come off. When i put a battery in it turns on automatically and i even removed the power button from the motherboard little power button & tried pressing that power button
I have a 5 year old acer laptop, it was working fine untill about a week ago. The problem is that once its connected to power it takes 2-3 mins for the battery light to power and for a weird reason while thats off the power button doesn't work.
I just uninstalled OpenSuSE 12.2 from my Sony Vaio laptop because the OS offered no "Shutdown" button on the desktop. I had to log out, and then just hold the laptop's Power button down 'til the laptop shut off.
i`ve just upgraded 11.04 to 11.10 in my laptop. before upgrade , no buttons or power issues at all. but when i the upgrade finished, i discovered:
1. my button power doesn`t work, to shutdown (before upgrade worked perfectly)
2. brightness button doesn`t work (fn+f9 or fn+f8), so i used Screen in system setting
