What harm does it do when the computer runs out of power directly?
Directly related to power on the machine damage, is actually a misunderstanding, somebody has done a test, as long as the hard disk does not work directly off the power will not have what harm, said before was directly related to power is actually refers to the hard disk harmful, if the hard disk read and write data is suddenly cut off the electricity or press the POWER key to shutdown, at this time hard disk from the disk and is in high gear, it is easy to make the head hit on the disk so as to cause the hard disk damage and data loss, it is terrible consequences, so a lot of people summed up is not directly shut down, in fact, hard drive manufacturers have taken many protection techniques to avoid the occurrence of such a situation, occasionally power off or crash directly after the restart will not bring much harm, as long as it is not in the format the hard disk, hard disk partition, upgrade motherboard BIOS or GHOST recovery When the mirror is turned off, there will be no problem, but for the sake of insurance, it is not recommended to turn off the power directly, or to shut the computer in accordance with the normal shutdown sequence! Will hurt a lot of things, but most of the hard disk or hard disk, die quickly, reduce the hard life that will leave the wrong file in the system tray, and cause the machine to run slowly or even wrong, sometimes even delete the error file can not be deleted, it may also affect the system, or the motherboard power burn and this occurs randomly, because the current may increase instantly, burn out the motherboard or other hardware, if you often do not circuit a few months of your hard drive or CPU hardware are not breakdown, not normal shutdown can be said to be hard hit.
When the computer is running, unplug the power directly, which will cause the following consequences:1, the user is running data can not be saved, resulting in data loss;2, the running download task, installation task, etc. can not be completed, resulting in download and installation failure.3, the running system update task can not be completed, it may lead to failure to boot.4, there may even cause the boot file is lost, which leads to not boot.
If the switch is by the power of the chassis, the normal shutdown is equivalent to the "start" - "off", because the Windows default settings, press this button is equivalent to a safe shutdown, and computer power are now using the ATX standard, so press the switch button is not immediately forced shutdown, to forcibly shut down must hold down don't put the button for 4 seconds (against the crash). If the old machine, the use of AT standard power, that button is equivalent to the ordinary power switch, and press it off, with the following destructive:
The killer of computers is the first to shut down the power, whether it is power failure or crash, or unplug the computer itself, so that the computer instantly cut off power. Light damage to data (if the system files are damaged will be able to start), heavy damage to the computer hardware (hard disk, power, motherboards, etc.), these hard physical scratches inside the hard disk is very easy to appear
