I just go a new Inspiron E1505 and it came with a PA12 AC adapter.  I have a number of PA10 adapters that I used with my Latitude D600 and Inspiron 8500.  I think the biggest difference is the PA10 is 95W adapter whilte the PA12 is a 65W adapter.  Does anybody know if the PA10 will work with the E1505.  I contacted Dell email support and did not get an answer except to call.
