It seems to me that if I have the Logos 4 application open, go to Standby Mode with my computer, then return from Standby to use the computer again, the computer consistently crashes / gives me a blank dark screen. After this, I need to power-down / power-up the computer. Please note that 1) I have a windows password that I need to log back in with after my computer returns from Standby, and 2) I was using an external monitor (HMDI connection) for the laptop.
