Ok so my Asus x200m notebook pc screen wont turn on but the cpu is on coz I can see three lights.. on the lightbulb symbol, on the battery symbol and on the tower symbol..what does that mean..and I cant remove the battery coz it has an internal one....and it doesnt turn on if I dont plug it...this started when I was working on a project while I was plugging it on ac.. then suddenly there was a blackout on our city but my laptop should stay on right coz it has a battery.. but now all I see is a black screen
