I just updated to Windows 10. Starting after I updated, my computer has started to shut itself down after waking from sleep mode. This only happens when I have the computer in sleep mode for a long period of time, i.e. overnight. I have not had this problem when putting my computer in sleep mode during the day and then waking it.
When I try to power my computer up in the mornings, it powers down instead, as if the power cut off. I have tried running the Power troubleshooter but that has not worked.
Anyone have any ideas?
