Hi, I got a new aftermarket battery for my laptop (Sony Vaio VGN-NR260E). Original was 6 cell, I got a 12 cell. The new battery shows a charge but will not power laptop at all. BIOS is updated and I do NOT get the "battery not detected" message. I also tried disabling "ISBUtility" in the System Configuration Startup list to see if that would work (read it online) but it didn't. Original OS was Vista Home, now Windows 7 (updated by pro long before I got the new battery). Computer runs fine on AC adapter. Anyone know how or if I can get the new battery to work? By the way, I know some stuff when it comes to computers but i'm a bit of a novice too.
