Dell inspiron 15 3521 won't start, battery light flashes on and off even on charger

I haven't used it in about 2 months (battery was in) I decided to turn it on and the boot screen came on for some seconds and then it went off. 

Even with the charger plugged in the battery lights just flash but it doesn't turn on.

I have few questions which would help us narrow down the issue to the faulty component.

When you press the power button, Do you get the Dell logo or nothing at all?

You may try entering the diagnostics mode to check if it lets us run the hardware diagnostics at least.

Remove the battery and charger. Hold down the power button, While you're holding the power button, Plug in the charger and let the button go. The battery is still out.

That should take you to the diagnostics screen. Let us know if you're able to get there.

Should the diagnostics fail, Please reply with the Error message and validation code, we shall take it further.
