Press your power button for as long as it takes to make the machine switch off completely. Start it up again and press your Windows key and R together. In the Run box that shows up, type cmd
then press the Enter key.
At the C:\ prompt in the black form that shows up and type
powercfg hibernate off
then hit Enter again.
You should see a success message but even if you don't, it will prevent the laptop from deep sleeping when you don't want it to.
