Can somebody tell me what a cold start is?

I was looking up ways to keep my laptop running as long as possible... & they said one of the main killers of a laptop is a cold start. So naturally I looked it up (they only place that actually seemed to talk about it in a computer sense was unfortunately wikipedia) & it was so damn technical that I could barely understand a word of it.

Can somebody PLEASE put it into layman's terms?

  • Hard reboot
    A hard reboot (also known as a cold reboot, cold boot or cold start) is when power to a computer is cycled (turned off and then on) or a special reset signal to the processor is triggered. This restarts the computer without first performing any shut-down procedure. (With many operating systems, especially those using disk caches, after a hard reboot the filesystem may be in an "unclean" state, and an automatic scan of on-disk filesystem structures will be done before normal operation can begin.) It may be caused by power failure, be done by accident, or be done deliberately as a last resort to forcibly retrieve the system from instances of a system freeze, critical error or virus-inflicted DoS attack. It can also be used by intruders to access cryptographic keys from RAM, in which case it is called a cold boot attack.[19] The attack relies on the data remanence property of DRAM and SRAM to retrieve memory contents which remain readable in the seconds to minutes after power has been removed.[19]

    In short, shutting down your PC without properly shutting down your PC will kill your PC.

    In essence, don't use the off-button. Use the shutdown procedure of your OS (Operating System, like Windows, Mac OS or Linux).

  • Well, it's technically used for the situations where a machine tries to run a procedure (either hardware or software based, it doesn't even have to be computer-related) when its components are not prepared yet, causing an imbalancedly timed turn of events that may cause various problems.

    It also sounds like a case of an insufficient start of a sexual confrontation, but I'm not the one for slangs.

  • So basically never turn on the PC directly after turning it off?

  • Or, never turn your PC off without actually shutting it down.

    E.g. don't ever touch the power button. Unless it's on your keyboard. UNDER THE FREAKING DELETE BUTTON.

    Okay... good then because I NEVER use the power button to turn the Laptop off. Thanks for your help guys :D

    Is yours like this? It's a really ackward design...

  • Yes. There were times I nearly wanted to throw my keyboard out of the window, but here in the Netherlands, you can get fined for that. Throwing junk out of your window.

  • Mine is right over it, but pressing it asks me if I want to shut off the computer, hibernate, etc.
    I do unplug it when it freezes, though. Which happens often.

    I had a friend living there. Sometimes he was talking about how much of a hellhole where he lives is, and I wasn't able to believe how similar it was to my country. Today I finally found a difference.

    I'm able to throw my bloody handkerchieves or whatever out of window simply because where I live is simply one large dumpster.

  • Yeah, when I hit the power button, it just causes Windows to go through its normal shutdown procedure. Now holding it for five seconds...well, my computer has a tendency to lock up every once in a while (and it's almost always because the graphics driver triggered a bluescreen), so I have to force it to shut down every once in a while. Mostly whenever I'm trying to play a Bioshock game.
