On my laptop, what is Hibernation Mode ?
Your laptop doesn't have an on-off switch, it has a power button.
Although that button may seem frustrating at times, it actually has one nice benefit, You get to control what happens when you press that power button.
Hibernation mode is a power-saving mode that conserves battery, but allows for a quicker resumption of operation than by fully turning the computer off and then back on.
When hibernation mode is activated, all current applications running in memory are saved to your disk, and the computer is turned off.
When resuming full operation, by pressing a button or clicking the mouse, the applications are read from disk and appear in the same state as before. You may hear from people that using this mode puts strain on your Hard drive, but most hard drives today in laptops simply turn off or 'Go to sleep' without putting any strain on them.
I personally don't like the hibernation option as it can cause problems restarting your Laptop or desktop even so I always turn off my computer if I am going to away from it for +4hrs or more, it also takes the strain off your built in fan.
It may take a little longer to restart if you turn OFF your computer/laptop but keeping control of what starts up makes it worth while.
