Switching in the usual mode requires pressing of the button start. But periodically single pressing doesn't work. It is necessary to press several times the button start, only then windows 10 is started. But in this case scrolling of the touchpad doesn't work. How to deal with this problem?

To open the "Run Command Box", press the Window key(+) R key together then type rstrui.exe and hit enter
The button is not worn out. The sound buttons are not different. Laptop new. Sometimes doesn't pass from the sleeping mode. For inclusion it is required to press several times and to wait.

Power on the system, quickly tap F12 continuously every second. It should take you to Advanced boot options.
