Avoid Painful Data Loses; Why You shouldn’t turn off your Computer by long pressing the Power button.

Some people ask if there is any harm in shutting down their computer by just pressing the power button for a few seconds, rather than going through the Windows shutdown procedure.


Besides both methods shut the PC down. As a matter of fact, holding the power button down for a few seconds is faster. The question remains, is it a good idea to do this?

To get straight to the point, it is a very, very bad idea to shut down your computer by holding the power button.

Before I start, let’s consider a bit about what a computer does during a standard windows shutdown procedure.


During normal running,

  1. A computer hard disk is rotating thousands of times a minute
  2. The little arm that reads and writes data to the hard disk is moving backwards and forwards all the time
  3. Windows may be reading and writing to the system registry

During a normal shutdown, (amongst doing many other things)

  1. Windows closes any files it was reading or writing
  2. Windows closes any access it has to the system registry
  3. The little hard disk arm is parked carefully at one side of the disk

So in comparison, what does holding the power button for a few seconds do?

Pressing the power button for a few seconds cuts power immediately to the whole computer.

What effect does this have?

  1. Any files that Windows was writing to may now have incomplete or corrupt data, because you didn’t allow it to finish writing properly.
  1. If Windows was writing to the registry, the system registry may now have incomplete or corrupt data because you didn’t allow it to finish writing.
  1. The hard disk arm, not being allowed to park by the side of the disk, may scratch or damage the spinning disk, causing data to become corrupt.


Each of these things can cause hard disk data corruption. So what’s the big deal about that?

Well, for a long time you might get lucky and the data corruption may be in an area of the disk that you don’t notice, or a file that you can do without.

But one day, probably when you need your computer most, you might find that one of your important programs no longer works because an important file is corrupt.

Or worse, Windows will no longer boot because the registry has become corrupt.

Even worse again, the hard disk might have so many physical problems that it has to be replaced, potentially losing all your treasured photos, videos and documents that you always meant to backup but never got around to do.


I bet you don’t want any of the above to happen to you.

So please, for the sake of your data, and to avoid a costly computer repair, take a few seconds at the end of the day to shutdown your computer properly.

Catch you all later for more exciting updates.
