I think you have no choice but to wait for the BIOS update.
I bought the v13 with intel core 2 duo 7300, 4gb ram, 320gb 7200 hard drive and Windows 7 32 bit. I think the product is fantastic but having a problem ? the fan is constantly staying on from boot. This contradicts all the reviews I have read about this laptop being quiet and energy efficient. I contacted dell but all they said was a bios update may be released in the next two weeks and that should sort it.
Has anyone else experienced this or have any advice? I love the v13 and its a brilliant product but if I cannot sort the fan issue its going back.
