So I have an Acer Predator Helios 300 laptop. Back in August I was using it and suddenly display freezed and when I restarted it, it just showed black screen, means it wasn’t working. But using HDMI I was able to use on other display .I went to nearest service centre and he told me that the display has issues and we need to change that part but RN we don’t have that in warehouse. And then I waited almost 2 months and still he said the same. Then I mailed company and did some things but still one more month passed. I again took out my laptop just to charge and update . Because I was about to go to service center tomorrow. All this time I kept it in cupboard. Now out of the blue , it just started and display started working . Everything working, all colors and refresh rate and all. So please tell me how is this possible. Suddenly it started working. My friend to me maybe it had heating issues.
