Hi all
Dell Studio XPS 1640, Windows 7, 64-bit, Home Premium SP 1, Bios A10 factory, I have tried, bios updates A12, A14 and A15, all will the result: error, cannot continue because… 1. no battery, , yes battery was at full charge, This has been going on for 9 months, I have posted this question to Dell Forums: no help at all, Called Dell Tech support: she checked everything and said the battery was bad, but would not warranty it because it was one year old. last week I bought a new battery and tried the Bios updates again, same problem, and yes battery was at full charge, have tried doing bios update in safe mode, no help, have used Dell and non Dell Drivers, used DriverMax to make sure all driver was up to date. old battery was Dell 6 cell factory, new battery non Dell, 9 cell, I used the Dell recommended battery model # for my laptop for new battery. Everything works fine, with or with out the battery & no AC
Also this laptop came from the factory as Vista, and the Windows 7 software came from Dell.
