Its from dell vostro. I use the same system on dell vpstro and hp zbook. The slider disapprered on dell vostro after this versiom update on that machine. Not loaded the os on zbook after update yet. Before upgrade the value did not stick between restarts on vostro. I was carrying the ntb while upgrading and it stopped responding with black screen and I had to force stop upgrade. I fixed the os after and finished upgrading from the version before.
