"Don't do that."
Use hibernation or just shut down.
I just bought a refurbished HP laptop off Newegg and I'm having some issues with it. After I close my laptop and it goes into sleep mode for while, it stops responding upon re-opening it and I have to hard restart it. It is becoming very annoying. It doesn't happen EVERY time I close my laptop, only after being shut for an extended period like overnight when I am asleep. I am running Windows 7 by the way. Can somebody please help me solve this issue?
