Windows 10 suddenly quit waking up from sleep mode-- the only thing that would do it was pressing the power button for a moment--not too long or it would shut off. This continued for 2 or 3 months then it suddenly started waking up again when I hit space bar on the keyboard--which worked for a couple of weeks now it has gone back to the previous condition(requiring me to press power button to wake it).
What the heck is going on and how do I fix it?
