No surprise if you were using hibernation. Hibernation saves the 
entire contents of memory to disk, in hiberfil.sys (a hidden system 
file), then powers off. When you power on, it restores the memory and 

The default of standby simply reduces the power consumption. As a 
result losing power during standby requires a full reboot.

Resuming from hibernate can cause problems for VA if the environment 
has changed, for example you've plugged in or unplugged the network 
cable, or the wireless network has changed. Under these circumstances 
VA may need restarting.

Apart from that, it is sometimes necessary to press alt-enter a few 
times to get the display back.
