Prefer Hibernate over Sleep Mode

Normally while we do not use our computer for short period of time we choose to take the computer in sleep mode or normally the computers come with that feature ( by default), but it better to make it hibernate than sleep.

What happens when a computer goes to sleep? 

When you put your computer on sleep mode, it saves "significant electrical consumption compared to leaving a device fully on and idle, but allows the user to avoid having to reset programming codes or wait for a machine to reboot. Many devices signify this power mode by a pulsing LED power light."

 What happens when a computer goes to Hibernate mode?

"Hibernation in computing is powering down a computer while retaining its state.Upon hibernation, the computer saves the contents of its random access memory (RAM) to a hard disk or other non-volatile storage. Upon resumption, the computer is exactly as it was upon entering hibernation.
When used to save power, hibernation is similar to sleep mode and saves more power at the cost of slower resumption."

So next time you want to put your computer on idle mode make it hibernate mode rather than sleep.

How it can be done?

For XP user:

They can enable Hibernation in the power option found in the control panel.
  1. Click start >>Turn off computer, the buttons “Stand By”, “Turn Off” and “Restart” will appear. 
  2. Now hold the shift key Standby will change to hibernate!

The windows 7, windows vista can directly do it from start button.

By default when you close the lid or push the main power button your computer goes in sleep mode. Change it to hibernate by going to power option

  • go to control panel-> power options-> and then choose from left side option as to what to do when you close the lid or choose what the powers button do and change it accordingly.
