Product Name: HP - Envy Touchsmart 17 Notebook
Model Number: m7 - j020dx
After upgrading to Windows 8.1, when my laptop enters sleep mode (from inactivity) and I touch the mousepad to awaken it, the laptop shuts off. It proceeds to try restarting but while loading it shuts off again. This will occur indefinately until I either manually shut it off and restart or sometimes if I just close the screen. I've reset the laptop twice after upgrading to Windows 8.1 because I thought that it would solve the problem, but it has not. The laptop was purhased in January '14 and is under warranty.
