Latitude E5420 won't work with external mouse on dock
I have an E5400 and an E5400 and two docks. Same models external mouse and keyboard on both. The E5400 works fine on both. The E5420 works only on one of them.
The E5420 won't detect the external mouse on one dock. Any suggestions?

Hi,
Thank you for reaching us.
Not suspecting any hardware failure as both the docks works fine with E5400, And E5420 works fine with one of the docks.
Can you check for firmware or driver for the dock which isn't working with E5420? That should help .
Thanks.
