Hello Timothy, Thank you for you answer. I really didn't inform all that it is necessary to expose my problem. I had already configure “battery and brightness” how you indicated. > What desktop environment are you using? I installed KDE and Gnome but I am using only KDE.

It will be S2 and S3 in BIOS. Yes, I disabled suspend via grub. The computer's BIOS is very simples (!) and it don't have config suspend item available (!!). Or it is hid an I don't still found it. > > When the device suspends I take it that you are not able to wake the device > properly by pressing the power button? No, without to disable suspend via grub, my laptop turned off by itself and when I pressed power button it turned on, it resumes working from the point where it stopped, but it does this action indefinitely. I disabled suspend via grub and this problem finished. However, when I started it and tried to log in or simply I wait, the screen turned off (black screen). When I get login system work without problems. > >> Enviado do meu iPhone > > > > -- > ⢀⣴⠾⠻⢶⣦⠀ > ⣾⠁⢠⠒⠀⣿⡁ Debian - The universal operating system > ⢿⡄⠘⠷⠚⠋⠀ https://www.debian.org/ > ⠈⠳⣄⠀⠀
