I recently bought a used Sony PCL-384L laptop. OI am hoping now it isnt stolen.... Opps!! Anyway, after system boots it goes to the windows login screen asking for password. Problem is, I have no clue as to what it is and cant contact seller. I know, it was/is a crazy deal on my end. I took it apart but could not locate a cmos battery, did i not look hard enough? What is the best, cheapest way to make the computer useable? I dont have any previous Vista info nor CDs. I have tried burning a few bootable CDs on a XP machine for help but they wont boot the system from the CD. Lost here......... Help please.
