KDMann Posted June 23, 2015 Posted June 23, 2015 When the computer goes to sleep the board loses connection. When we wake the computer the connection is still lost and the PC needs a restart. This has become a site issue and have been looking for solutions. Please advise
NB9457 Posted June 23, 2015 Posted June 23, 2015 What board is it? We have a similar issue with the latest Smart Boards that have a separate PSU instead of being powered by USB. Usually for us turning the plug for the board on and off fixes it, but it i in no way ideal and I've tried to find a fix (reimage, new drivers, old drivers, different PCs) but it seems site wide with the new boards.
Network_Boy Posted June 23, 2015 Posted June 23, 2015 Have you tried disabling USB selective suspend? Go to control panel > power options > change plan settings > change advanced power settings > USB settings > USB selective suspend settings > set to disabled.
mikeprice Posted June 23, 2015 Posted June 23, 2015 rubbish solution - but extending the timer so it doesn't go to sleep during the day would get round the problem until you find a proper fix

I also had a problem like this last week with one of the same generation boards with separate PSU. I reached the same conclusion - take out the power lead to the board and put back in. Voila. Not an ideal solution, mind.

It is a pain as the teachers look at me like I'm stupid, they think it's broke, when technically it isn't, just seems of a poor quality.

NB9457 Posted June 23, 2015 Posted June 23, 2015 I'd say the best route may be to disable sleep mode, stop USB ports going to sleep and disable hibernate too, only allow screen off/shutdown. That's why I tend to do, it's not ideal, but sleep mode in the past has caused me too many headaches, plus if someways away from a computer long enough for it to sleep, it should be off in my eyes.
