After I close the lid of the laptop it doesn't enter in suspend mode. This happened immediately after an update of Ubuntu 18.04. I use the setting suspends when the laptop lid is closed OFF until I find a solution.
Why it doesn't suspend mode work?

In Ubuntu 18.04 Gnome desktop, there’s no option in Settings utility for configuring laptop lid close actions. And Gnome Tweaks only offer a switch to enable/disable ‘Suspend when the laptop lid is closed.
Follow the steps:
- Open Terminal
- Paste the following command in the Terminal
sudo gedit /etc/systemd/logind.conf - Provide your system password if it asks.
- Now you need to find the line #HandleLidSwitch=suspend & uncomment it (Remove the # from the beginning).
It will be like the below image:
Save and exit the file.
- Now restart the Systemd service using the following command:
systemctl restart systemd-logind.service
That's it, This method will fix your issue.

I was also facing the same issue. So you may have switched to Nvidia graphics drivers. If that's the case, just switch back to Intel and restart.
