I may have a solution to the very annoying low battery alert sound that plays @ 40%. i have done this on my phone and am @ 40% with no alert sound. if somebody could also verify it working that would be great.

using your regedit of choice go to:
HKCU/controlpanel/soundcategories/battlowalert

i changed initvol to 0 and default sound to a file that doesn't exist (e.g. nophonelowbat.wav).

i am using wm 6.5 so this may not work on 6.1.

let me know if it works.
