Starting the computer when its power is turned off. To perform a cold boot if the computer is running, select Shut Down. Once the machine is off, turning it back on performs the cold boot. Show If the computer locks up, a cold boot is necessary because a restart ("warm boot") may not be sufficient. A cold boot removes power and clears memory (RAM) of all internal data and counters that keep track of operations, which are created by the OS and applications when they run. Erratic program behavior is often cured with a cold boot, also known as a "hard boot." Remove the PowerEven when shut down, computers may occasionally retain settings in RAM. The only way to absolutely guarantee RAM is cleared is to remove the power source, which means unplugging a desktop computer or removing the battery in a laptop. Laptops with non-removable batteries are typically cold booted (reset) by holding down the power button for 10 or more seconds. Sometimes another key or button must be pressed along with the power button. A/V EquipmentTVs, A/V receivers and set-top boxes generally draw power when turned off, and they must be cold booted by removing their power cables to reset them. Contrast with warm boot. See boot, clean boot and hard reset. When a user presses the power button on their computer, it initiates the process known as "booting," which loads and starts the operating system. Booting can also be thought of as a series of actions where the ROM of the computer is accessed in order to load the startup instructions. After that, the operating system is loaded from the disc that is now being used to boot the computer. A primary option for the boot disc is frequently the local hard drive. The process of booting the computer is finished when the operating system is loaded; at this point, the computer is ready for usage. There are two types of booting − cold booting and warm booting. Read through this article to find out the difference between cold and warm booting. What is Cold Booting?To do a cold boot on a computer that is already operational, select the Shut Down option. In order to complete the cold booting procedure, the computer must first be powered down and then restarted. If the computer locks up, you will need to do a cold reboot because a reset (also known as a "warm boot") may not be sufficient. During a cold boot, the computer is powered off and its random-access memory (RAM) is flushed clean of any confidential data and registers that were created by the operating system and applications while they were in use. It is common practice to perform a cold boot, sometimes known as a "hard boot," in order to remedy erroneous behavior exhibited by software. In order to guarantee that all of the data in the RAM has been removed, it is necessary to disconnect the power supply, which means turning off a desktop computer or removing the batteries from a portable computer. To perform a cold boot on a laptop with a battery that cannot be removed, it is common practice to hold down the power button for ten seconds or longer. In addition to the power switch, it's possible that another key or button has to be pressed. What is Warm Booting?When a computer is hanging and not working properly, you can restart it so that it can function normally again. Warm boot does not turn off and does not erase data when powered on. It makes a big difference when paired with a cold boot. Before putting the system to use, it performs a self-diagnosis, also known as a POST, and loads all necessary drivers. Even before the operating system begins to run, the computer goes through a number of steps that are collectively referred to as "booting." On the other hand, the term "warm boot" refers to the process of resetting a computer to its initial state while simultaneously maintaining the power supply. Warm booting is more prevalent than cold booting due to the fact that consumers frequently leave their computers in a sleep mode even when they are not using them. The power-on self-test is skipped during warm booting, although the remainder of the boot procedure is finished normally. All of the software files on the system that have been updated since the last time it was rebooted will also be loaded. It suggests that you are beginning the process of resetting the computer by simultaneously pressing the "Ctrl, Alt, and Delete" keys. You can also perform a warm boot by selecting "Restart" from the menu bar and hitting the button. After a few seconds, your computer will eventually go back to where it was initially and finish the process. Difference between Cold and Warm BootingThe following table highlights the differences between Cold Booting and Warm Booting −
ConclusionThe boot process that you select is actually contingent on the issue or error that the system is producing, which can be anything from a frozen program to an application that is unable to respond to a required system reboot following an upgrade in the system's firmware. If an application does not react, a simple reset command will be enough to put the system back to its initial state during a warm boot. This means that the power supply will not need to be turned off throughout the process. On the other hand, a cold boot is particularly effective against system crashes, which would otherwise require you to undertake a thorough system diagnosis by forcibly rebooting the system. A cold boot begins the computer in its normal operating state. One of the drawbacks of doing a cold boot is that it initializes all of the hardware from scratch, which results in the loss of all of the user's stored data.

What is iDRAC power cycle system cold boot?Power Cycle System (cold boot) — Turns off and then reboots the system. When prompted to confirm the action, click OK. The managed system performs the selected power operation.
What is the difference between warm boot and cold boot in iDRAC?The technique of restarting a system from a power-off state and returning it to normal function is known as cold booting. On the other hand, Warm booting is the technique of restarting an already-on system without completely turning it off. Cold booting conducts a more thorough system reset than warm booting.
What is the difference of warm boot and cold boot?Rebooting a computer through the menu option or the keystroke combination is sometimes referred to as a warm boot, perhaps because it is more gentle than the alternative cold boot (simply pressing the computer's power button once to turn it off and then again to turn it back on).
How do I reboot from iDRAC?In order to reset the iDRAC, without rebooting the operating system, press and hold the System Identification button for at 16 seconds. Stop pressing the button when the cooling fans start spinning at full speed and the front LCD (if present) is turning off. Now the iDRAC restarts without changing any saved settings.
