I want to replace the Battery in my Sony clie UX50. I have been told that I need a T6 torx screwdriver, but it does not seem to fit. I have also tried a T3 T4 T5 and T6. but with no luck. The battery came with a screwdriver that says 630, but no luck with that either. By the way Sony quoted me 200 for replacing the battery, how crazy is that!

If you can help, thanks.
