> PTP [image] A lot of questions are asked about PTP. In this post a short explanation about PTP. What does PTP mean? PTP means Pull The plug. Make sure the power is off so not connected anymore. Pull the plug out of her! Now don’t put it back in too soon. Some say a few seconds is enough but experiance is learning that we need to power her down for at least 10 minutes. On the forums and on Slack u can see a lot of “11.2 minutes” power down. This ofcourse is a joke. The minimum of 10 minutes…
