If the battery "goes dead" after sitting for several hours, but only when key is left in the ignition, in the "off/lock" position. The problem may be with the stereo amplifier staying on. Our technicians tell us reprogramming the affected control module can remedy this problem.Google+

Saab 9-3 The Battery May Go Dead After Sitting For Several Hours
Saab 9-3 Problem
I have pretty much the same problem except it dies with the key in or out. I have to jump it almost daily after sitting over night. Once I jump it I have no problem all day but going to start it the next day, its dead all over again! My radio went out, screen and sound but seems to still be on even with the fuse pulled and the car off. Ever since that happened ive been having this problem! This is so frustrating and no one know exactly whats wrong or causing my car to die. How do you reset it? I would love to give it a shot, hopefully it will save me the constant headache!!
