Can just restore drivers directory?
I have an Acer Travelmate 3200 laptop which the screen is now blank when
it boots up. Even if I redirect the screen output to an external video screen
or TV, nothing shows up.
However, if I boot up this laptop using Acronis boot CD (which comes with
its own video driver), it was able to display on the screen as well as on the
external display devices.
Looks like the video drivers or certain drivers are now corrupt.
I have taken an Acronis backup (full image) about 6-7 months ago
when everything was still working. However, I don't want to restore
everything as some new data & applications have been installed
the last few months (including Canon drivers). So I just want the
drivers directory (& if possible video-related drivers & drivers for
the CPU to communicate to video) to be restored.
Where's the drivers' directory & can I just restore like this & it
will work or some registry entries need to be updated as well?

>I just restored using Acronis a backup taken about 6 months
>back & it could not output to an external display
Type correction to the above: I meant it COULD output
to an external display.
I'm pretty sure it's not LED as this is a 5 year old laptop,
Acer Travelmate 3200 (& LED technology is not prevalent
yet at that time).
If I boot up from an Acronis boot CD several times, sometimes
this Acer laptop's built-in LCD display fine, sometimes not.
So intermittent kind of issue.
Currently I'm using an external display.
>Is the screen correct (brightness)
I've pressed the required FN key to set brightness to the max,
no joy.
I'll try out the instructions in the 2 links below:

& it could not output to an external display but the laptop's LCD
itself is extremely extremely dim even if I press the FN key to
set it to the brightest.
Looks like LCD issue?
then I boot into safe mode & try to redirect the display back to
the LCD screen by pressing FN F7, it still outputs to the external
display & on the LCD, it's still extremely dim (you've got to strain
your eyes to be able to see a little dimly lit display).
If I were to get a working (used) Dell LCD to replace this Acer's LCD,
would it work?
