Updated everything on my 9550 after following the Dell recommended install guide.
1. Only way dock works is by connecting to dock after a complete shut down and restart of windows. If connected while hibernating only the monitor works. The USB and Ethernet do not. USB audio is very glitchy - sometimes it will remain connected sometimes it wont.
2. No stability. After "working" for a variable amount of time 5 min to 30 min... monitor will flicker (displayport connection) and dock will drop all USB connections and ethernet.
3. Fan constantly running on low in the background. If on AC adapter... Fan shuts off.
4. Once connections are dropped. Laptop needs to be completely restarted before it will even consider connecting. Then if connects it will constantly drop USB/Ethernet and constantly try to reconnect.
Update is effectively useless. Dell needs to fix this or I will be forced to return it.
