Issues with Power On

[dunnb]

Hi! In June at the end of the last school year, I had all of my laptops set up to Power On with no problems using Veyon. Since we've been back to school, however, I seem to lose that control with a few machines every time I use Power Off. They all respond to all commands including Power Off, but then a few will power back on automatically and can no longer be powered on using Veyon.

Any ideas what might be happening? Thanks in advance!
