I can log to the lattitude e6430 when i boot it but when my computer goes to sleep and ask for a password again box will not show up. This computer is new nothing is installed yet just windows with the last update 1607 i think. I cant remove the lock screen because we are more then one user on this computer. I try all the old fix i think but nothing help i flash the bios, i install the laptop new driver, i contact dell they give me garbage support with an answer that doesn't fit at all my problem. I forgot my sister have the same exact computer and she have the same problem.
