Question Dell G15 getting power but not turning on

[hydro210]

2 days ago out of nowhere my G15 5520 decided not to turn on. I plugged the charger in and it still had the led telling me that it's charging. I suspect it had something to do with sleep mode (i only closed the laptop but didnt shut it down, ik u should turn it off but i was very tired and i just closed the laptop and left it like that overnight). I've been charging it for a while and it still doesn't turn on. Doing any sort of activity (like pressing a key or the power button) just makes the charging light blink once (white charging light is on, disappears for a second, white light is back). I've already tried hard resetting as well and nothing. Any help?

how did you hard reset it?

took out the battery and held the power button for 30 secs

 

[helpstar]

remove the HDD/SSD and try powering on, pressing the F12 button multiple times

remove one RAM stick (one still seated), exchange the slots with one stick

check charging port
try different charger with same voltage and at least the same current/wattage or more

replace battery (check the battery voltage with a multimeter)
