Dell Laptop Slow on Docking Station

Posted on 2016-08-15

I have a user with a Dell E5540 Laptop connected to a Dell E-Port Plus II. The laptop runs extremely slow when on the Docking Station. When removed from the dock it runs fast with no lag when opening docs or web pages etc. The laptop used to run fine on the docking station.
I replaced the Docking Station with a new one, but this did not help. I also updated the Video card drivers, but again, no change.

Has anyone experienced this same issue and found a solution?

Are you using the same network cable on the laptop as on the docking station? Is the laptop wireless when not in the dock. If the latter, is the network cable good?

Besides, are you using the bundled power adapter which comes with the docking station?

Install the latest smart connect drivers to see if that helps

1. The laptop uses a network cable connected to the dock when on the Docking Station and operates wireless when off the dock.
2. I am using the larger power brick that came with the Docking Station.

Did you check the network / cable / switch setup?  You tried two docking stations.

What happens when you take the laptop out of the dock and connect it by Ethernet?

Thanks to everyone for all the excellent suggestions, but the problem no longer exists. For some inexplicable reason, the problem has disappeared. The  user told me that when she connected to the dock yesterday the problem did not occur and it has not recurred since then.

Thanks again,
Mark
