Wake with Mouse from sleep but not hibernate

I have a Dell Optiplex 380 Desktop. Running Windows 7 Professional 64 bit. I have been able to wake the system up from sleep mode using the mouse or keyboard, but can only wake from hibernate using the start button on the front of the tower. That tells me that I probably have the right selections made in the Power options and in the Device Manager. In the BIOS, I have disabled the Low Power Mode. In fact, I have tried many different combinations of settings, but to no avail. Any suggestions would be appreciated.

there is no way to awake the computer with either mouse or keyboard when in hibernation state.

hibernation is the same then turning the computer off. Except that the state the computer was in when going into hibernation mode is written to the hibernation partition/file which will allow for faster boot.

Thank you for the reply. I was getting ready to disagree with you based on what I thought was happening on my Windows 8 computer. I always use the keyboard or mouse to come out of what I thought was hibernation. Turns out I had both sleep and hibernate selected after 30 minutes, so the computer was probably going to sleep, and never made it to hibernation. Manually hibernating the computer required pushing the start button on the front of the tower. I do understand the differences between hibernate/sleep/hybrid sleep, and the hibernate file that gets created, but my settings involved user error on my part. I was never hibernating, just thought I was.
