That's it, really. Two tightly-knit black lines a quarter of the way along the top and two tightly-knit 2" lines a quarter of the way down, a third of the way across.

Is my laptop about to die?

Thanks!

Yeppoon, QLD, Australia.
a picture of the screen may be helpful too.

but no, your laptop is not about to die, I've seen people use theirs with this issue for years.
it is a sign that the monitor data cable running up through the hinges is flaky.
worn? corroded? old? - don't know.
or the screen lattice work of cells has failed in parts.

any chance it's been dropped, knocked, stood on, abused recently? :)

is it under warranty still?
do the lines change if you (gently) twist and bend the screen?
what about if you poke the areas slightly?

Hello, and thanks. Hasn't been knocked, dropped, and so on, not under warranty, and nothing happens when poke or twist.

I've tried several ways to produce screenshot, but the lines don't reproduce.

Half and inch from the top, starting at the left edge, there's a single extremely thin black line 4" long. Halfway along it and for about an inch-and-a-half there's a second extremely thin line directly underneath.

Nearly three inches down, four inches from the left are two extremely thin adjoined lines an inch-and-a - half long.

All are increasing slowly in length.

It's a Lenovo G50-80, by the way.

Thanks!

How's this?

By the way, just in case anyone might be interested, that is the sun setting between remains of Mulberry HarView attachment 5001bour on Gold Beach, Arromanches on the evening of the 70th Anniversary of D-Day!

Sorry, I missed the specs request earlier. I know this is a silly question, but where do I find those?

Have you tried hooking up the notebook to an external screen to see if the issue is replicated on that screen.

As an asides ennnceee, noticed in Speccy that you have multiple AV installed, bad idea :(

Antivirus
Avast Antivirus
Antivirus: Enabled

Virus Signature Database: Up to date
Windows Defender
Antivirus: Disabled
Virus Signature Database: Up to date
Malwarebytes
Antivirus: Enabled

Virus Signature Database: Up to date

Windows 8, 8.1 and 10 come with an improved Windows Defender, it offers the same real-time anti-virus/anti-malware protection as Microsoft Security Essentials. Windows Defender also shares the same malware signature definitions as Microsoft Security Essentials, and Forefront Endpoint Protection. Technically, Microsoft Security Essentials has not been renamed Windows Defender, or combined with it in Windows 8, 8.1 and 10.

Having more than one AV installed on your computer is bad, it will slow down the computer, cause internet connection problems and leave you with no AV protection at all if they cancel each other out as they fight for resources.

If any AV product that you have is a paid for version you should always make sure that you have a copy of the product key kept somewhere safe just in case you ever wish to reinstall it.

You can uninstall Avast in the Control Panel but should you have any problems see Avast clean removal info here Please create a new system restore point first.

Malwarebytes removal info here

Thanks, have uninstalled Malwarebytes, and will investigate with external monitor.

It is 100% hardware related then :(

Screen most likely but to see if it could be the MB to screen video cable, using your thumb and two finger in the the middle of the top cover try gently partially closing and reopening the top cover while the notebook is on just enough to be able to see if the lines move as the lid is opened and closed.

Can I ask that you do not quote replies, it really does not help any and just makes for unnecessary reading, thanks.

I wasn't aware I had, format somewhat confusing (to me).

No, lines don't move.

Thanks.

The fact that the lines do not move goes some way to suggesting that it is the screen that is bad, if it were the video cable you would expect a change in the display, flickering or the black lines getting larger etc.

Quite a big job swapping the display and not something that a complete novice should undertake, take a look at the example dismantle guide here

You are welcome btw :)

Not really. I couldn't try it myself, so guess I need to get someone who knows what they're doing to look at it.

Interestingly, the top line has dissipated to quite an extent, although the other one is very slightly bigger.

Does it seem to you to be something that requires urgent attention?

You could keep using the notebook as it is if you can live with it, the alternative is to have the screen replaced with something like the example here

If you do order a screen you need to confirm for yourself that you are ordering the correct one, we only had the Lenovo G50-80 info that you provided to go on.

Thanks. I'll live with it for the moment and then go for the replacement if it gets too much. Strange that the top line/s have faded to an extent, perhaps the other will as well. We'll see! Thanks for your help.
