TP Power Manager/Battery Gauge Modification

[Stadsport]

I know this is a long shot, but does anyone happen to know where the files for the taskbar battery gauge is stored on Windows 7? I've peaked through all the binaries (with ResHack) at C:/Program Files/ThinkPad/Utilities/ and found tons of graphics used in the actual Power Manager utility, but none for the battery gauge itself.

Basically, I'm looking to modify the graphics to make them fit with my Windows theme a little better.

If anyone could point me in the right direction, I would be really appreciative!
