To start my PC or to resume from hibernation, I usually tap the spacebar on my keyboard.
No apparent starting/running issues starting from a cold boot or if NOT using the hibernate feature.
However, if resuming from hibernate, I am often unable to enter the password at the logon screen (The keyboard doesn't respond to attempts to type the password, but the mouse works).
After hitting the reset button on the box, the PC occasionaly has some issue, then seems to run fine after scandisk or another reboot process.
In the interm, I have disabled hibernation, but would like to use it for power savings and convenience.
