open the case and look at the capacitors on the motherboard. if their caps are bent outwards or have gunk coming out of them you need to solder new ones or get a new motherboard. dell's are notorious for putting in cheap capacitors that blow up (check if theres a recall)

you can also try to re-seat the ram/cpu/gpu. if you take the ram out and power up it should give you beep codes.

if that is not the case it could be a failed power supply (not giving enough juice.

I have fixed several power sockets on Dells - You don't know until the battery goes so low the system cuts off.

.  It may be blinking a code telling you what is wrong. Check your manual or go to Dell's website for more info.
