Hi

We are running more than200 dell computers in our company. lately we purchased E7240 for some users but it looks like the AC adapter does not work with the Dell E-Port docking station we have and that cause the USB hubs not to function at all.

currently the workaround is to plug the AC adapter to the laptop instead of the docking station. is there anyone who had the same problem ? can give more information ?

our BIOS is updated to the latest version. also a message comes up when the ac adapter connected to the docking station before the windows boot up saying the ac adapter won't charge :()

Appreciate your help.
