What to do if the laptop is in hibernate mode?
When you press a key on your keyboard and your computer is in Hibernate mode, it will trigger a “wake up” signal restoring your machine to operational state. In Microsoft Windows XP, there are two sleep options available: Hibernate and Stand By. Stand By is the more traditional sleep mode. This type of sleep mode lowers down the power your computer uses to almost nothing.
When you’re in Stand By mode, the power to your peripheral devices, hard drive, and screen gets cut off but the power to your computer’s physical memory or the physical RAM remains allowing your files to stay open. In Hibernate, the computer saves an image of your desktop which includes all open files and windows and then it shuts down your computer.
When you turn your computer back on, all the files and windows are open just as you left them. In Hibernate mode, it is safe to unplug the power of your CPU but in Stand By mode, you will lose data if you unplug the machine. When your computer is in Hibernate mode, you don’t need to freak out when the system is coming back online.
The noise you hear is just the processing of the system. In a desktop computer, Hibernate is not enabled by default. But when you’re using a laptop, Hibernate is enabled by default because it is mobile and it often runs on battery.
