Hi Alexandre, I think the issues I may have had are from the screensavers. If I let the screen timeout on it's own and just blank things seem to work OK if I activate the Screensavers doesn't seem to matter which one I pick weird things happen. Can anyone else confirm this? I do usually use a screensaver I have two machines one I use at work for meetings and testing that runs 8 hours a day but usually only gets used a couple of hours unless I have a massive amount of meetings. The screensaver on this one is more for security so I can lock the screen. The other is used at home ( it is a larger unit don't like to carry it around ) usually that gets used an hour to three a night 5 days a week and shut off each day. On the weekends I usually leave this machine on all day so I can use it whenever I want without having to wait for it to boot, so I usually leave a screensaver on that one as well but not usually locked. Both machines are Intel CPU's with Intel graphics. I believe both are based on the Sandy bridge chip set. I will continue to test and see what I can find. Overall the new version is very nice.
