I normally close the lid of my laptop at night but it remains on.Yesterday I forgot to do so. It shuts off the display but is set not to shut down or sleep or turn off harddrives.When I move the mouse I see a white vertical Band exactly the 1/4th the size.Now to be clear the problem does not exist anymore It has become allright But i want to know what caused it if it is a hardward problem as my laptop is still under warranty I can replace the laptop if the next time it does the same thing.So I don’t have screenshots or photos but I recreated them in photoshop as it was pretty simple.Here is what happened in sequence.1. I have a another monitor connected which was working perfectly This Laptop display showed this and would not turn on nothing would appear.
Then I was fiddling around I tried touching the edges tapping it to see if there was any loose connected but it did not seem like it. Nothing changed from what I did I could see a lot of bleedeing from the edges which became more prominent and now 4 bands appeared of equal width like below by itself as I was browing the internet on the extended monitor looking for some solutiosn.
Then I restarted the laptop and I could see the Bios logo with the same band but now it was bit lighter Then the desktop was visible everything was fine the band was lighter.Like this
Here I found that The Laptop screen is using the Intel graphics card. while the Extended Monitor is using the Nvidia Graphic card. So I found there was a driver update for the intel and updated it.There was no change I restarted the laptop a few times it started to get lighter the band or at least it seemed.I work no the extended display. So when I was searching online for help I noticed the band had changed it had dropped from the top around a centimeter like below.
Then I kept searching for more then I pressed my screen after a few minutes when I looked back at my laptop screen it was gone. I restarted the laptop a couple of times Even the Bleeding now is less (as much as it was when I got the laptop there is a slight bleed of white light on the right which I checked is pretty normal for this range laptops) Then the laptop was idle so the screen turned off when I turned it on it was perfect.So If anyone faced this I would please like to know what causes this. If it is a weakening Display card (In this case the intel which is embedded in the Motherboard) then maybe the next time it happens I should try to get a replacement?Is something causing it.Just for the record nothing fell on it the laptop was working find at night I just went to lie down and fell asleep in the same room the laptop was not touched at all no chance anything fell on it.Thanks.
