Whats the difference between a cold boot and a warm boot for PC/Mac systems?
The cold and warm boot perform slightly different functions. A warm boot is “restarting” the computer while it is already in the “powered on” state. The power to the system is never turned off. This type of reboot is also called a “soft reboot.” Most times when a system is not responding or in a hung state, a warm boot will suffice to reset the system. Warm booting gives your system a chance to reload the operating system and reset your software. A cold boot is performed when you turn the power off on the computer. It is also called a “hard reboot.” This type of boot takes longer than a warm reboot. I usually recommend that you leave the system “powered off” for a few minutes (about 2-3 minutes) before powering the system on again. A cold boot is especially helpful if you have tried a warm boot and your system is still having the same trouble.
