[Tails-testers] Error in 3.0 Alpha 1

on a lenovo Ideapad Y570 on a DVD or USB created using Tails installer
the laptop does not securely erase the ram & shut down, I did check the
known and long standing issues but this did not happen on 2.7 & any
other Tails OS I have tested

Because it did work but does not work now I assume something could be
changed to fix this as something was changed which broke it

The caps lock button does flash like stated on the known issues page
