There are many reasons
for a laptop screen to go
black, and most of these
causes can be fixed
easily. Major technical
failures are harder to identify, and expensive
to repair, but you may
want to try these
solutions first.If you find that your laptop
screen has gone black
suddenly, you must know
that there are a number of
possible reasons for this. It
would be impossible to accurately ascertain the
exact cause by mere
speculation, as there are
many wires, connectors, and
devices, that need to
function properly, to keep the screens of laptop
computers working
properly. If the screen turns
black randomly then you
must not panic, and should
follow a systematic troubleshooting procedure
SCREENSAVER:The most obvious reason
why this happens, can be a
screensaver. This is a mode
into which the computer
progresses if it is left idle for
a stipulated amount of time. In order to get the machine
out of the screensaver mode
all you need to do is move
the computer mouse around
a bit, or hit any random key
on the keyboard. You can also change the settings of
the amount of time a
computer must be idle
before it goes into the
screensaver mode. To do this,
right click on your desktop, select 'Properties', choose the 'Screensaver' tab, and then change all the settings that you wish to change.
Hibernate or Standby ModeIf your laptop is left idle for
a long time, it sometimes
slips into hibernate or
standby mode automatically,
in order to preserve power
in the laptop battery. All you need to do in this case is
press the power button, and
the laptop will switch back
on. In most cases, you will
reach a screen where your
computer will be locked, and you will have to choose one
of the user icons that you
see. If you have enabled
password protection then
you will have to enter your
password as well. If your screen turns black after a
few minutes then you must
press the power button, and
see what happens.
Computer CrashOne of the most complicated
reasons the screen goes black
is a crash. This could occur for
a variety of reasons, and is
often difficult to fix. You
will have to take the machine to a computer repair
shop, and they will open up
the laptop there to find the
cause. Needless to say, this
could set you back by a few
hundred dollars as well. The crash could be caused by
overheating, or maybe even
a loose power supply cable.
One solution for you is to
play an audio file if the
laptop goes black. If it does not play at all, then
something is wrong with
the entire system, but if the
audio file plays, then it is just
the laptop screen that is
troubled.
Virus AttackThere are a few computer
viruses that can cause this
problem, but most antivirus
programs can effectively
deal with such a virus.
Update the antivirus software regularly, and
make sure you download all
possible firmwares, and this
sort of virus will be
successfully thwarted. If
your machine is infected with such a virus then your
video drivers will most
certainly be affected, and
even your video card could
get contaminated. All these
results in the computer screen going black, and in
some instances, the screen
may even go blue.
Outdated Drivers and ProgramsThe video drivers are crucial
for making the computer
monitor function properly.
On some occasions though,
these programs can stop
functioning due to various reasons. If your screen turns
black after startup on a
consistent basis, then maybe
it is your video drivers that
are malfunctioning. To avoid
this situation, you should constantly upgrade your
video drivers, and should
also refrain from using
pirated ones. Spend those
extra bucks on getting
licensed drivers, and you will save a lot of unnecessary
expenditure in the future.
Also, update your video
drivers, as and when the
new updates roll out. These
updates are usually meant to iron out the little issues that
may pop up now and then.
