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:
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
I installed SMXI on my laptop and ever snce then I've noticed an intermittent problem where it will not power off.Shutting down the laptop gives the appearance that everything is shutdown, i get the text display after selecting shutdown and the the screen goes black. To the casual observer it would appear that the laptop has switched off, however the power LED on the side of the laptop
