johnoo Posted September 6, 2015 Report Share Posted September 6, 2015 Set to go to sleep after 30 minutes.But when I go to wake it nothing happens.Have run the Lenovo Diagnostic system & no faults found.Also ran Microsoft "Troubleshooting for "Power" & again no faults found.Only way to restart is to unplug from mains supply & then do new restart which takes place with no problems.AS interim measure have set computer so that it never sleeps, but how do I cure this problem?
