Re: Inspiron 1545 AC Adapter Not recognized

I agree EJN63.  That person's response is arrogant, uninformed and useless (to say the least).  I too, have worked on thousands of computers over 30 years and within the last few years, have noticed an obvious degradation in the Dell brand -- specifically their laptops.  This "AC Adapter  = Unknown" message found in the BIOS is one that has been well documented for the past few years with their Latitude laptop line.  Contrary to the assertion that this problem is primarily caused by the consumer's "rough handling of the power supply and/or power jack" is erroneous.  Use your Search Engine and you'll see lots of technical possibilities that can be at the root of this particular model's seemingly inherent flaw.
