Turn Off Lenovo Low Battery Sound?

I own a Lenovo Thinkpad Yoga S1 and I'm really annoyed by the low battery sound. I'm aware that there's a way to turn it off, but I was wondering if there was a way to change the sound.

Yes. Right click the volume control and then click sounds. Scroll down to low battery and click the browse button. Browse to the folder that you have custom sounds and choose the sound you want. There are literally thousand of wavs online you can download. Just type wavs and look for what you want.
