I have a Latitude D620 and my battery stopped charging . I found the error code" 3600:0649 Invaild AC Adapter reported".  Luckly I had a second adaptor so when I changed AC adaptors my battery starting charging again.

I don't think the adaptor is my problem, I have 2 Inspiron 6400, I have no problem with the other laptop using the same adaptor.  The adaptor seems to be charging the battery without problem.

I fixed my problem by getting a different AC adapter.  Sometimes the adapters go bad.

I have an Inspiron 6400 and I'm getting the same error code. The laptop freezes on the initial windows page, and won't load windows (7 upgrade from Vista). The BIOS is A13 and I know there is a version A14, but I have no idea if this part of the problem, and I'm at a loss to figure out where to go from here. Do I reformat and resinstall all software, or is this even necessary? Is the motherboard finished? Or am I missing the boat here?
