Having the computer in Hibernate mode is not a good thing. Majority of the people that has hdd failure to often becayse of that. Speacially if you do it everyday. If you think about it. Your HDD spins around 7200 rpm. When the computer goes not hibernate mode. It stops. When you touch the mouse, your hdd has to spin at 7200 at instant from the start.Thats not a good thing. Leave the computer on, keep the screen saver or turn of monitor. Turn off once a week for few hours, to clean the ram memory and let the computer cool down.
