Kali has issues with Booting

[Vladik Y.]

Hey, Everyone!
I've recently have installed Laptop-Tools in Kali via:

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

/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!

I'd check the output of dmesg and in /var/log. Take a look at the latest entries in both, you should see error messages pertaining to your problem.
