I recently changed the button battery on the hard drive of my XPS 420, as the battery was low. I now understand I need to know the BIOS settings/system setup info, for the computer to boot to windows. I checked in the manual, and it only tells you to write down the BIOS settings before changing the battery...ugh! wish I looked there first...I'm presently using windows 7.
I tried doing a search for this info, but found nothing.
Any help would be appreciated!
