I have looked up for a solution on several forums but can't find it, hope I didn't miss it ! I have a laptop and I am used to turn it into sleeping mode by pressing the physical power button that is on the right of the laptop. But for a few days this button is acting as if I pressed ctrl+alt+delete (same screen with lock computer / switch user etc.). I have checked the parameters in the control panel / choose what the power buttons do and they are correct : sleeping mode ! I can change it but it doesn't change anything. I have checked in the control panel / power option / change advanced power settings : everything seems to be OK and if I change it nothing change for real.
I can't remember changing anything this precise day or the day before it happened...
Does anybody have an idea ?
Don't hesitate if you want anymore information
Thank you for reading and for your answer :)
