Borrow and swap in another PSU of the same or greater wattage and see...

NOTE if its an older DELL unfortunately you need a DELL PSU...

I replaced batteries in my electric razor because I thought they were faulty.  I failed to realize that the power plugs were dead.  Thank goodness my GF tried to fire up the hair drier before I tossed out the razor.  Lack of sleep tends to mess up my troubleshooting.

I'm simply trying to say check the power plug source is good.
