In the past 3 days I have experienced 2 potentially related problems with my school acer chromebook (CP713-2W-P5GP)
1) When I use my laptop, I find vertical lines appearing on my screen, distorting it and becoming larger and more apparent as time goes by. At half of the maximum brightness, it takes 5 minutes for the lines to become visible. I've found that decreasing the brightness of my screen causes the lines to take much longer to become visible (Over 20 minutes at 1/4 brightness), and increasing it does the opposite. I've also found that ¨resetting¨ my screen eg by closing the lid or shutting off the laptop causes the whole cycle to reset, making the lines disappear and come back after the aforementioned time.
2) There are also horizontal white lines at the top of my screen, also distorting it. At first, there were only one or two lines but now it takes up about 8-10% of my screen and has slowly increased to double in size over the past few hours. I've also noticed that they flicker occasionally, changing in brightness.
Here is some other information which may be important:
I first noticed the problems in the same 10 minute period of me using the laptop.
There have been 2-3 unfortunate points in time where I have left the laptop in my school bag and then dropped the bag from about a 15cm distance on the floor when I reached home before I noticed the problem occurring, so my carelessness could be the cause
I have tried to power on and off the laptop a number of times as well as press and hold the off button, both to no avail.
If anyone could help me with this problem I would be very grateful.
