[ubuntu-uk] It Hibernate better than switching off?

[Tyler J. Wagner]

I don't believe you can instruct a suspended laptop to wake itself up. That 
would take at least a BIOS feature, I think.

A suspended laptop doesn't make a copy of anything. It just syncs the 
filesystems (writes changes to media), and puts the hardware into a low-power 
state. That basically means that RAM remains powered and everything else is 
effectively off. When you restore, the data is still in RAM.

Regards,
Tyler
