Product: EliteBook 840 G1
Operating System: Microsoft Windows 7 (64-bit)

Hi All, 

 

I have an EliteBook 840 G1 with a docking station. When I have the laptop connected to the docking station the network is fine. 

 

If I leave the laptop connected to the docking station, turn the laptop off and then undock it, and then turn it back on, once the laptop has logged on, it runs incredibly slow, and the CPU has a 100% usage. If I then reconnect it to the docking station or connect a wired network connection to it, it suddenly starts working normally again and CPU usage drops to a normal amount of usage. 

 

So it's a wired network issue. Can I fix this? No I don't seem to be able to.  I can only find A temporary fix, which is to uncheck LAN/WLAN switching. This is not ideal as we need to switch to LAN when docked to access certain shared drives.

 

Things I have tried: 

 

Updating Network drivers

Updating Docking station drivers

Updating BIOs

Uninstalling Network drivers and reinstalling them 

Disabling network card and re-enabling it 

Updating the Windows 7 image 

Turning LAN/WLAN switching on and off (restarting in between)

Updating Various other drivers that were long shots at fixing the issue. 

 

Any ideas? other than turning off LAN/WLAN switching?
