From past few days i am facing very peculiar problem. Whenever i hibernate my laptop, the screen goes black and it wont turn off completely even after hours. I have to manually turn it off by pressing power key for few second. I have tried restarting but the problem resurface on hibernation. Whats interesting is the process of saving the hibernation files seems to get completed properly because whenever i turn on the laptop next time it resumes properly. Any way i can find out whats hampering the windows to turn off? Using Windows 10 Pro Dell Inspiron 3542.
