Whats the difference between Hibernate and Stand by on laptops?

Question

and can they be dangerous or affect my laptop ?

Answer 1

While it is slightly different for every manufacturer...
Normally in Stand By, the computer continues to run, but at a reduced state. It powers down the monitor, hard drive, network card, etc., and about the only thing it keeps running is the memory, which holds the currently programs and data. When you "wake up" the PC, it repowers everything and continues to run Windows and your programs. While in stand by the computer contiues to use power. If it should run out of power (battery goes dead), it will save the memory to a file and switch to hibernation instead.

When you "hibernate", the computer first saves its memory to a file on the hard drive. Then it powers down everything including the memory. During hibernation the computer does not use an power. When you wake up the computer, it restarts. Only instead of reloading Windows and everyhting like a normal boot up, it reloads the file dump of its memory and then can continue to run from the same point where it was put into hibernation.

Answer 2

hibernate saves all the application data onto the hard drive and shuts down then reboots with the same data it saved bringing up the stuff that was there before
standby just turns off the monitor and any unused components and sits there until it has input eg you press a button or move the mouse

Answer 3

In standby mode, the computer isn't off, it just has the various peripherals (monitor, HDD, etc) powered down.

In hibernate mode, the system takes a snapshot of what is in the RAM memory and writes that to your HDD and actually powers down. When you start the next time, instaed of having to reload Windows and all your programs, it just reloads this snapshot and you;re ready to go.
