One of my laptops is finally dying. At least, the screen is; it has a
beautiful magenta tint.
I'm running openSUSE 13.1 on it (I upgraded two days ago) and I'm pretty
sure it will run a second monitor through the VGA socket on the side. My
question is, therefore, has anyone here tried to remove a laptop screen
and then boot the machine?
I have a feeling it will fail POST, but does anyone know different?
BTW It's a Toshiba A110-274

I haven't tried removing the screen and booting it, but replacing a
laptop screen isn't difficult - I think I found a spare for an old Dell
laptop I have around here on eBay for pretty cheap. I know I found
motherboards there as well.

Good point. However, firstly the only screens I can find are in the £60
range and the machine ain't worth that (data's all backed up, so no loss
if scrap it). Second, I was thinking of letting The Feegle have it to
watch Peppa Pig on. If I put a box round it, it would look like Pappi's
machine and he'd feel very grown up. :-)

If the whole screen looks fine apart from the lack of a green component
in every pixel, then I'd say the issue is before any of the electronics
actually inside the screen. It might be worth re-seating the flat
cable(s) between the screen and the main board in their connectors first
to see if that fixes it. Or if you're unlucky there might be a break in
the tracks on the actual cable - but that should be easy to test for (if
you have a meter that can measure resistance) and you might be able to
pick up a spare.

I don't see any reason why it shouldn't work, but can't you just disable
the internal screen in the OS?

It's an uneven magenta tint with a bright green spot in the top left
corner when I mouse-over it.

The problem is POST. I can set the OS to ignore the internal screen.
I'll try some experiments this weekend providing that The Feegle gives
me some space.

I'm not sure about laptops, but IIRC the classic POST just checks for
the precence of a graphics card (or the onboard equivalent), and gives a
damn whether there's actually a display connected to it.

That is very encouraging. I'm still not going to try until the weekend -
a laptop in pieces would be too tempting a target for The Feegle.

You mean the colour tint changes depending on where you move the mouse?
If you want, post a photo of the screen whilst displaying a plain white
and then plain green background, and I'll see if I can figure out what
has happened.
