Yesterday night i turned off the laptop. It said "windows is getting ready dont turn off", I did the same and left it to take its time. then checked again after a while it was turned off. Then day when i turned on the laptop. It turn on with same dell splash screen and all, but then it turned in to a black screen with out even prompting me to give the login pin, as in windows 10. Then I turned it Off, Since thennnn i am trying, it isn't turning on at all. When i plug the charging cable its charging, LED turn off briefly and turns on back as it happen always when ever charging is plugged while laptop is off. But when i press the power button i get the "kirrr" sound from CD-Rom and very brief blink of LED, but it never turns on. I tried the Hard reset method of removing battery and pressing power buttom for 30s and putting the battery back, but it didn't turn on. Instead of 30s i kept pressed power button for 5min even then it didnt turn on. I tried by removing the battery and just turning on the laptop on AC with charger plugged. But again the same, "kirr" sound and it fails to turn on. I also tried to Open hardware diagonastic with Fn + power button, in both ways, with battery and without battery on AC, but it didn't responded there was nothing. Its just charging thats it. Please help me with this
