The BIOS normally wakes up the machine, and this can vary between laptops. (Even in Windows.) I have a Toshiba laptop that will wake up with ether the power button, or opening the lid. I have an older Thinkpad that will only wake up if you hit the power switch. I have also used laptops that would wake up if you hit any key on the keyboard. Exactly what wakes up the laptop may be a setting in the BIOS, or you may have to run a setup program to set things up. On a lot of machines, you have to install a utility package specific to that laptop before it works right in Windows. This sometimes prevents you from upgrading Windows on the laptop because the utility does not work on the newer version of Windows. Because you usually don't have the program for Linux, you end up having to do a bit more configuration to make it work. Now, it can get even more interesting setting up hibernation - a lot of laptops create a file that the BIOS uses to store the information during hibernation. Few laptops have Linux utilities to create this file, and tell the BIOS about it. But Linux does have suspend to disk option that will use the swap partition to save the information. You have to use the resume= option in your kernel command line when you boot. This causes the kernel to check that partition for resume information at boot, and if it finds it, it will then restore from there.
