∙ 14y agoIf there is no power to a computer then it will cease to function just like any other electronic device. normally this will not cause an issue unless the computer was sending data to be recorded on the hard drive, in which case loss of power can cause random garbage to be written to the drive. This in turn can cause the system not to initialise during the next switch on.
Use of a UPS (uninteruptable power supply) will reduce the likelihood of damage cause this way.
