So doing a dance show and I'm sitting next to my sound tech when without any warning the MacBook running QLab literally passes out (AKA goes to sleep). Track stops. Panic ensues from the dance staff. We wake it up and the track resumes.
In the following moments I googled possible issues since the laptop was on AC power and had all the power saving features disabled. Turns out placing certain magnetic devices on the palm rest will convince the laptop that you've closed the lid and it subsequently shuts down.
My tech's glucose monitoring device has a magnetic component in it and that did the trick. Just thought I'd share. Apparently this also happens with some phones.
