This is a 2015 model of Samsung notebook 9 (purchased new 2016 Nov). Problem occurs only in battery mode not when connected. Screen will show static, go black, and then computer shuts down. Comes back on when I reboot, and will function fine for a while until problem repeats.
Thanks. But my display allows only 60 hertz, and is the same for both modes. Also, I realize I was not clear in my posting, and have revised it now. It's not just the display going blank but the system itself shuts down.
You might want to try checking the settings in "Control Panel", "Power Options", "Change plan settings" and then "Change advanced power settings. Check all the different options listed, as it could be one or more of them that is having an effect. Once you have made all your changes then click "Apply" and then "OK".
