Warm Boot

Definition – What does Warm Boot mean?

The warm boot is also known as a soft boot that means restart a computer. It is used in contrast to a cold boot that refers to starting-up a computer that is turned off. Typically a warm boot is started from the operating system, by pressing a button on the computer itself. In order to perform a warm boot on a Windows operating system, you may need to choose option Shut Down or Restart from the Start Menu. If you use a Mac OS, you can perform a warm boot by choosing Restart option from the Apple Menu.

Glossary Web explains Warm Boot

Warm booting is a more common term than the cold booting since most computer users leave their PC in sleep mode when they do not use them. While a home PC may not need to be turned off for months, it may need to be restarted every few days in order to complete new software installations. Even though a warm boot doesn’t contain a power on self-test like a cold boot, it performs the rest of the boot and loads any system files that were installed before the PC was restarted.
