I have a Acer Predator Helios 300 - PH315-52 model gaming laptop (The blue one, with blue backlight keyboard). It was working last December 30, 2019. Today after turning it on, the LED screen of the laptop and light of the logo predator at the back of it does not work at all. But when I plug it on a different monitor as extended screen through Windows 10, all were running good except the laptop screen and predator logo light of the laptop cover. What do I need to do, please help. I've checked the BIOS version and date, currently it is BIOS version 1.02 and the date was April 2019. The laptop was a new release last year of 2019.
