Hello, I'm using dell Inspiron 3521..
Today, I looked at my laptop and noticed that charging light (white) is on and charger was not even connection... I clicked power to swich on my laptop but it didn't and meanwhile the charging light was on..
then I removed the battery and pressed the power button for 30 sec and the. reattached it and tried to on it..
But it didn't..
Please help me out...
That would leave the mainboard as the faulty part - if under warranty, contact Dell; if not, it may not be worth repairing a low-end system that's now about four years old.
