So I recently booted up my old XPS to give to my brother in law and the external battery will not hold a charge, nor will the computer start with it connected. I get the following error: Warning: The battery attached can not power the system. The system will not boot with this battery plugged in. Press F1 to shutdown the system.
When I disconnect the external battery and keep the a/c power connected the computer will run fine. I updated the bios to a newer version (A05), and when I went into the bios to check on the battery it said it was not compatible. Now, we did order a new one straight from Dell, and it came 80% charged, but it still said that battery was not compatible either.
I was able to wipe every thing and install Windows XP Professional on it (damn 2 gb ram), but besides that I have not touched anything but the updated bios.
