Hey, Everyone!
I've recently have installed Laptop-Tools in Kali via:
Code:
apt-get install laptop-mode-tools
nano /etc/laptop-mode/laptop-mode.conf 
/etc/init.d/laptop-mode restart
and I have changed the settings so that the tools will run even with AC apter plugged in with:
ENABLE_LAPTOP_MODE_ON_AC=1
Code:
/etc/init.d/laptop-mode restart
laptop_mode start

Output:

Laptop mode 
enabled, 
active [unchanged]
After this, I've rebooted my laptop and normally when my laptop boots up there are no checking messages ( [OK] SOMETHING or [DEPEND] SOMETHING ) but this time there were some! and Kali didn't Boot up the last one was a positive one. Then I've Pressed CRTL+ALT+F2 and logged me in and typed: reboot and Kali bootet up this time normaly!

Please help me fix this! And if you know what the issue is please explain it to me! Thanks very much!
