Inspiron 5559 13 months old - ac type & wattage cannot be determined....

Have the following 2 symptoms:

  • When turning it on, I get an error from BIOS which says AC type and wattage can't be determined and thus battery won't charge.
  • I have a spare battery which when inserted shows that is is 62% charged. But even with that, if I pull the power cord, the laptop doesn't stay on.

I have seen few posts regarding updating BIOS which I did. Doesn't seem to make a difference. Any suggestions.

This symptom started happening on this laptop at least 2 months ago when the laptop was in warranty. Unfortunately, I was a little late in calling Dell and the awesome Dell support says it is 25 days out of warranty so won't fix anything :-( So much for my 6th Dell laptop.

First step:  try a new OEM  Dell AC adapter.

If that doesn't solve the issue, replace the DC power jack:

One of those two parts should solve the issue -- if not, it's the mainboard that's bad.
