To enable the super to function in Unity as 'normal'.
Remove the dell package
sudo apt remove dell-super-key
Install CCSM to modify the Unity Shell settings
sudo apt install compizconfig-settings-manager
In the "unityshell" plugin, under the tab "Launcher" there is an option for "Key to show the Dash, Launcher and Help Overlay". Ensure that this is set to "<Super>"
Every two minutes the wifi connection slows, this is observable when running these commands (one on a server and one on the laptop)
nc -lk 2112 >/dev/null dd if=/dev/zero bs=16000 count=62500 | nc -v $SERVER_IP 2112
And then use nload to monitor, every two minutes you'll see the graph of network throughput drop dramtically.
nload -t 64 -i 300
The solution is to set the BSSID of the wifi profile, so that network manager doesn't scan.
To do this edit the wifi connection, ensure the BSSID has the value from the drop menu selected.

Sometimes after resuming from suspend the bluetooth stops working, the only way to solve it is to do a full shutdown (not a restart)
When there is heavy load on the GPU or when charging, there can be an audiable noise coming from the machine - which is apparently coil whine.
