[WinXP, Ubuntu] (PanP4) Can't Disable Annoying Low-Battery Beep

I've got a pangolin performance, which I purchased december 2008, and it's been great so far, except for one thing: when I'm on battery power, if my power level reaches 9%, the system begins to emit a very high-pitched, very LOUD beep every 2 seconds or so. This doesn't seem to be a very useful feature... one beep would be plenty to warn me. I don't want my laptop beeping at full volume while I'm in a seminar.

I've tried going into sound settings in both winxp and ubuntu, and disabling ALL sounds, but the low-battery BEEP BEEP BEEP persists unless I actually mute my volume. I've checked the BIOS settings, and there is a "low battery beep" option, but it's disabled.

Has anyone had this issue? What can I do, beyond simply turning my sound off once my laptop battery hits 10% power (not a satisfactory option).

Please try the various suggestions in this thread...

They didn't fix it in Hardy (8.04), but, at the end, it is reported to have been fixed in Intrepid.

What about winxp? Am I stuck with the beep if I'm booted into windows?

To be honest, I don't know my way around WinXP to tell you how to disable it.

I googled "disable low battery beep windows xp" and it pulls up quite a few threads dealing with that issue. You might give that a try.

Or, 76ers? Anybody out there dual-booting a PanP4 and experiencing this problem?
