I have recently ordered a new battery from Dell for my Inspiron 9300 laptop. I have both a 90W power adapter and a 130W power adaptor. The computer will run correctly on AC power, but the battery will not charge above 36%. When the AC adaptor is unplugged, and then plugged in again, it says that a 90W adapter is required...even though the adapter used is 90W. I have gone through the BIOS, and both 90W and 130W adapters show as unrecongnized power sources.

Anyone have any ideas?
